Connection integration pipe trench construction method on pipe trench

Abstract

The invention relates to a connection integration pipe trench construction method on a pipe trench. The method comprises the steps that 1, steel plate pile supports are inserted into the two sides ofa trench to be excavated, and the top ends of the steel plate pile supports are fixed by adopting easily-detachable temporary supports; 2, the trench is excavated; 3, steel rails are laid at the two sides of the trench; 4, an integration swing frame is placed on the steel rails; 5, an adjustable butt-joint frame is placed on a steel base plate; 6, a connecting bolt is used for penetrating throughbolt holes in flange plates of adjacent pipes, and the adjacent pipes are fixedly connected; 7, the integration swing frame is used for swinging the connected pipes; 8, the easily-detachable temporarysupports are disassembled, the pipes are laid down into the trench, and the trench is backfilled with backfill materials. The method has the beneficial effects that the pipes are supported on the trench through the adjustable butt-joint frame, the pipe connection precision can be effectively improved, and the structure reliability can be improved.

Description

technical field [0001] The invention relates to the pipeline construction of the drainage pipe ditch, in particular to a method for constructing the overall lower ditch with the upper connection of the pipeline ditch. Background technique [0002] Drainage trenches are generally constructed by excavating trenches first and then installing drainage pipes. The pipeline is transported to the bottom of the trench by hoisting section by section, and then lengthened section by section. However, there are many problems in this construction method: the pipeline is not tightly connected, and water leakage is prone to occur at the interface; under the long-term erosion of water flow, the soil around the pipeline is easy to be hollowed out, causing pipeline settlement and collapse; If it is carried out at the bottom of the ditch, the operator needs to have enough space for the connection operation. Generally, it is necessary to over-excavate a part of the soil, which increases the cro...

However, there are many problems in this construction method: the pipeline is not tightly connected, and water leakage is prone to occur at the interface; under the long-term erosion of water flow, the soil around the pipeline is easy to be hollowed out, causing pipeline settlement and collapse; If it is carried out at the bottom of the ditch, the operator needs to have enough space for the connection operation. Generally, it is necessary to over-excavate a part of the soil, which increases the cross-sectional area of ​​the ditch, thereby increasing the workload of the earthwork; the overall slope of the pipeline is difficult to control, so Affect the drainage effect and cause sedimentation in the pipeline, which will easily block the pipeline after a long time
