Pipe jacking construction process

Abstract

the invention discloses a pipe jacking construction process. The pipe jacking comprises steel pipes. The pipe jacking construction process comprises the following steps of: excavating a steel pipe groove; respectively fixing a winch on the left and right of the rear of the steel pipe groove; excavating a soil tank vertical to the steel pipe groove on the top of the steel pipe groove, arranging channel steel in the soil tank, and fixing iron piles on two sides of the channel steel; welding a steel pipe connecting sleeve at one end of the steel pipe; sleeving a conical head on the head of a first steel pipe, sleeving a cap on the tail of the first steel pipe, and hanging and connecting a movable pulley, wherein the movable pulley is connected with the winches and is connected with the steel pipe through a linkage device, and a fixed pulley is fixed to the iron pile; twisting a plurality of circles of steel wire rope on the winches; and jacking the first steel pipe, detaching the cap, sleeving the head of a second steel pipe on the tail of the first steel pipe, arranging the cap on the tail of the second steel pipe, and repeating the process until the steel pipes are jacked to pass through the road surface. The pipe jacking construction process can reduce the damage to the road surface, reduce application of large vehicles and environmental pollution, has short construction time and low cost, and has the characteristics of energy conservation, emission reduction and efficiency improvement.

Description

technical field [0001] The invention relates to a construction technology, in particular to a construction technology for pipe jacking used for cable construction. Background technique [0002] With the development of social economy, power cables are widely used due to their safe operation, less maintenance, and beautiful appearance. In traditional cable construction, excavating the road surface to lay cables is a common method, but it is difficult to restore the road surface to its original state after the construction is completed. Most of the low-voltage user projects are small, and large and uniform pipe jacking equipment is used. Due to the large size and heavy weight, the construction area is large, and the greening on the roadside is often damaged. The pre-dug pits seriously affect the mud. The appearance of the city has been damaged, and the environment has also been polluted to a certain extent; this construction method takes a long time and costs a lot; at the sam...

In traditional cable construction, excavating the road surface to lay cables is a common method, but it is difficult to restore the road surface to its original state after the construction

Most of the low-voltage user projects are small, and large and uniform pipe jacking equipment is used. Due to the large size and heavy weight, the construction area is relatively large, and the greening on the roadside is often damaged. The pre-dug pits seriously affect the mud. It also caused some pollution to the environment; this construction method takes a long time and costs a lot; at the same time, it is also limited by the progress of the project and the geographical location.
