How to install the lifting column? Tongda Zhi explains the steps of the lifting column installation process

The choice of installing the lifting column is generally to prevent the vehicle from forcibly passing through restrictions on passing vehicles, so that pedestrians and electric vehicles can pass well, and the traffic order and the safety of major facilities and places are guaranteed. For the installation of the lifting column, many security personnel have some doubts, so how to install the lifting column in the end, what is the process flow? Today, Tongda Zhi explained the installation steps and process specifications of the lifting column in detail:

1. Construction site materials and equipment preparation before installation of Tongdazhi lifting column

1. Stone: The bottom of the foundation ditch is covered with a layer of 3-5 cm in diameter and 20 cm in thickness.

2. Sand: 20 cm above the water seepage layer of the foundation ditch. The amount of stone and sand is calculated by multiplying the length of the ditch by the width of the ditch. The width of the road pile equipment is 1 m, and the distance between the ditch and the center of the installed pile is 1 m. Or according to the length of the site construction.

3. Reinforcement: The underground piles of the road piles are used to reinforce the welded steel bars. The diameter of the 1.4mm threaded steel bars is 6 pieces according to the length of the groove. According to the width of the groove, each of the pre-embedded barrels is slightly longer when welding. It needs to be inserted into the four walls of the foundation trench, which is stable and not displaced after the equipment is buried in the barrel.

4. Concrete: Calculated according to the base area of ​​the base and multiplied by 90cm, the pavement recovery cement or asphalt stone is calculated according to the field usage.

5, 1 inch thick-walled polyethylene plastic pipe, according to the distance of each road pile to the control box on the site and make a reservation, each road pile is the root, the control box is required to be buried between the power box and the cable box. Pipe protection.

6, cable: control box input main voltage 220v (RVV 3 * 4) 380V input: (RVV 3 * 4 + 1), cable. Control box to road pile equipment cable (the road pile with warning light cable is RVV7*2.5; the road pile without warning light cable is RVV5*2.5; also can use two lines, road pile with warning light RVV3*2.5+ RVV4*1.0; road pile without warning light RVV3*2.5+RVV2*1.0), one for each road pile. One roadblock equipment grounding wire (BVR4). The required cable lengths are reserved at both ends of the distance between the site control box road pile equipment and the control box to the power supply equipment.

7. Cable wiring tape: electrical plastic tape, high-pressure waterproof tape, asphalt tape, prepared according to the number of field devices.

8. Tools and equipment: welding equipment, pavement cutting equipment, electric picks, foundation trench excavation machinery, and other electrical and civil construction tools and equipment, and on-site safety construction facilities.

9. After the on-site installation materials and our company's equipment are ready, follow the relevant safety construction standards and do site construction safety measures. Determine the installation location of the road pile equipment: no pipelines, cables and other facilities that affect the construction, refer to the construction standards of the relevant local facilities.

10. After the site has the construction conditions, determine the installation and construction date, arrange the technicians as needed, and guide the installation remotely or on site.

Second, Tongda Zhi lifting column equipment installation foundation construction standards

1. Foundation trench excavation construction: foundation groove depth (1.4 m), width (0.7 m - 1 m), length (the total length of the center distance installed by the road pile equipment is 1 m). It is required to do the necessary construction plan before construction to avoid damage to the road surface and other facilities outside the construction area.

2. Draw the construction area of ​​the foundation ditch on the ground of the installation site according to the design plan. If the road surface is a hard pavement such as cement or asphalt, first use the electric saw to saw along the four sides of the construction area of ​​the foundation ditch, and then use the electric raft. The electric equipment removes the ground above the area to avoid affecting the ground outside the construction site, which brings inconvenience to the road surface after installation.

3, the basic ditch requires four walls vertical ground leveling specifications.

4. If there is frequent water accumulation at the construction site or the groundwater level is high, our technicians will set up the corresponding drainage facilities according to the site conditions. If our personnel are not on site, please contact our technical staff to develop a solution.

5. After the foundation trench is dug, the bottom is filled with 3-5 cm of stone, and the thickness of the seepage layer is 20cm----30cm and then filled with fine sand with a thickness of 10--20cm. Evenly flat, does not affect the placement of the ultra-flat base of the next pre-buried barrel.

Third, the equipment embedded parts installation

Insert one end of the 1 inch threading tube into the pre-embedded barrel and hold it with waterproof tape. Insert the depth to about 30MM, and the other end to the equipment control box, one for each pre-embedded barrel. When laying the threading pipe, it is required to ensure smooth threading and cable replacement when there is a fault.

2. Threading and grounding: Each barrier device is individually driven by a cable (the barrier is illuminated with RVV7*2.5 cable; the non-lighting strap is RVV5*2.5 cable or other specification cable), to the control. A separate threading pipe is required for each cable. It is required that no cable is inserted into the pre-embedded bucket, and it is taken out from the pre-buried bucket to the top of the pre-embedded bucket, and is 1.3 meters above the top of the pre-embedded bucket. 0.7 m, the grounding wire uses a BVR24 alone. One end of the wire is connected to the grounding bar of the control box, and the other end is connected to the welded steel bar of the pre-embedded copper. A m8 screw is welded on the reinforcing bar and pressed with a screw cap.

3. Control box power supply connection: a cable is laid from the control box to the power take-off box. The input voltage of the control box is 380V, RVV4*4 is selected, 220V is selected as 3*4 cable, and the threading pipe is separately prepared. The cable is required to be inside the control box. The lead is reserved for 1 meter, and the length of the power take-off box is reserved according to the terminal in the power take-off box.

4. External controlled button box wiring: If the user requests to configure external manual button control, lay a (RVV*1.5) cable along the control box to the manual control box, and lay the threading tube separately, and the cable at the bottom of the control box must be reserved. Less than 1.2 meters, there are external control terminals in the control box, open, close, stop, and common four terminals. The three lines of opening, closing and stopping are respectively connected to the corresponding normal opening points of the manual control box, and the common line is connected at the same time. At the other end of the normally open point corresponding to the three buttons

V. Welding pre-embedded barrel reinforcement

1. Rebar welding process: After the cable is laid, it is necessary to reconfirm the intersection line between the pre-embedded barrel and the foundation ditch, and start welding after height, vertical and concentric level.

2. The first layer; welded with a steel bar into a well-shaped fixing frame centered on the pre-buried barrel, welded and firmly welded three layers, requiring two ends of the steel bar to be inserted into the four walls of the foundation ditch, the first layer is from the bottom of the pre-buried barrel

30 cm, after the welding is completed, the pre-buried barrel is corrected again, and it is determined that the second layer is welded after being prepared, otherwise the pre-buried barrel cannot be corrected after the second layer is welded.

3. The second layer is the same as the first one, welded in the middle part of the pre-embedded barrel, and the third time is 20 cm from the upper part of the pre-embedded barrel (the welding method of the steel bar can refer to the product technical guide to install the welding schematic)

Sixth, the wiring part of the process
