Embodiment 1
[0032] A construction method for a municipal comprehensive pipeline channel, comprising the following method steps:
[0033] Step 1: Locate the coordinates and direction of the pipeline according to the requirements of the construction drawing of the pipeline design, and perform piling and laying out to determine the position, width and depth of the trench;
[0034] Step 2: Use mechanical grooving for piling and laying out. If there is a pipeline below, use manual grooving near the pipeline;
[0035] Step 3: Tamp and level the groove, and lay a waterproof cement mortar bonding layer;
[0036] Step 4: On the basis of protecting the anti-corrosion layer of the pipe body and not damaging the concrete, the personnel will use the high-strength nylon belt to hoist the prepared prefabricated U-shaped pipe for mechanical lowering;
[0037] Step 5: Appropriately add sand bags to both sides of the assembled U-shaped prefabricated pipeline placed below to stabilize the assembled U-shape...
