Hydraulic bollard installation steps and construction specifications
Hydraulic bollard installation steps and construction specifications
1. Equipment installation foundation construction standards
1.1. Foundation trench excavation construction: foundation trench depth (1.4 meters), width (0.7 meters-1 meter), length (according to the total length of the center distance of the piling equipment installation plus 1 meter). It is required to make the necessary construction plan before construction to avoid impact and damage to the road surface and other facilities underground and outside the construction area during construction.
1.2. Draw the construction area of the foundation trench on the ground of the installation site according to the design plan. If is a hard pavement such as cement or asphalt, first use an electric saw to cut along the four sides of the construction area of the foundation trench, and then use an electric pick. The similar electric equipment clears the ground above the area to avoid affecting the ground outside the construction site and causing inconvenience to the restoration of the road surface after installation.
1.3. The foundation ditch requires four walls to be vertical and the ground leveling specifications.
1.4. If the construction site often has water accumulation or the groundwater level is high, our technicians will set up corresponding drainage facilities according to the site conditions. If our personnel are not on site, please contact our company's technicians in time to develop solutions.
5. After the foundation trench is dug, fill the bottom with stones of 3-5 cm in between, make the water seepage layer with a thickness of 20cm----30cm, and fill in fine sand with a thickness of 10-20cm cm. The thickness of each layer is required. Evenly and flat, does not affect the placement of the outer cylinder in the next step.
2. Installation of equipment embedded accessories
2.1. Laying equipment installation horizontal line: along the center of the vertical ditch [ditch length direction] of the foundation, draw a straight line with a rope at both ends horizontal to the ground, and horizontally [ditch width direction] according to the center of the installation position of each equipment and the ground level. One line forms a cross positioning line for equipment installation. Both ends of each line are required to be fixed and tightened with steel nails without shifting.
2.2. According to the height of the outer cylinder of each equipment, backfill or clean the fine sand at the bottom of the base tank to make the height of the outer cylinder of each equipment above the base tank consistent.
2.3. Equipment installation link: put the rising bollard into the excavated foundation pit and level it, and place the overall piling equipment vertically and stably to avoid loss of personnel and equipment. It is required to be consistent with the upper horizontal line, to ensure that the center of the outer cylinder and the intersection of the center line are consistent and vertical. Use steel bars to weld and fix it first to prevent the outer cylinder from shifting when the lower tube is threaded.
3. Laying the threading pipe and threading
3.1. Laying of prefabricated threading pipes: pay special attention to [there is a pre-embedded pipe on each side of the outer cylinder of the equipment, the lower is the drain pipe, and the upper is the wire tube. Do not connect the threading pipe to the lower drain pipe, otherwise the equipment Other units will not be installed]! ! ! ! ! Insert one end of the 1-inch threading pipe into the outer tube and hug it tightly with waterproof tape. The insertion depth is about 5--10MM and fix it with waterproof tape. The other end is placed in the control box of the equipment, one for each outer tube. Requirement when laying the threading pipe: ensure that the threading is smooth, and the cable can be replaced smoothly when there is a fault
3.2. Wire threading and grounding link: each barricade device separately thread 2 or 3 cables into the control box. On the end of the control box, mark the serial number in advance according to the order of the columns. Each cable goes through a threading tube separately, and each cable is required to pass into the outer tube and lead out from the outer tube to the top of the outer tube. It is 1 meter higher than the top of the outer cylinder, 0.5 meter is reserved for the lead out of the control box, and a BVR 2m㎡ is used separately for the grounding wire. 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 outer cylinder, and an M8 screw is welded to the steel bar and pressed with a screw cap.
3.3. Control box power connection link: Lay a cable from the control box to the power-taking box. Use RVV4*4m㎡ for the input voltage of the control box for 380V, and 3*2m㎡ for 220V. 1 meter is reserved for the lead-out inside the box, and the side of the power-taking box is reserved for the length of the terminal in the power-taking box.
3.4. External controlled button box wiring: If the user requires external manual button control, lay a cable (RVV4*1.5m㎡) along the control box to the manual control box, and lay the threading pipe separately. The cable at the bottom of the control box is required to be pre-wired. The length should not be less than 1.2 meters. There are external control terminals in the control box, four terminals for open, close, stop, and common. The three wires of open, close and stop are respectively connected to the corresponding button normally open points on the manual control box, and the common line Simultaneously connect to the other end of the corresponding three key normally open points
4. Welded outer cylinder reinforced steel bars
4.1. Rebar welding process: After the cable is laid, the cross line between the outer cylinder and the foundation trench must be reconfirmed, and the height, vertical, and concentric level will start welding.
4.2. The first layer; the outer cylinder is the center and welded with steel bars to form a well-shaped fixing frame. The three layers are welded firmly. Both ends of the steel bars are required to be inserted into the four walls of the foundation trench. The first layer is 30 cm away from the bottom of the outer cylinder. Calibrate the outer cylinder again, and weld the second layer after making sure that it is ready, otherwise the outer cylinder cannot be calibrated after the second layer is welded.
4.3. The second layer method is the same as the first one, welded in the middle part of the outer cylinder, and 20 cm away from the upper part of the outer cylinder for the third time (the steel bar welding method can refer to the installation and welding diagram of the product technical guide)
