Description
Technical Field
The invention relates to the technical field of underground pipe gallery construction, in particular to a new and old pipe gallery connection method for reducing uneven settlement.
Background
With the development of society, more and more cities begin to conduct the construction of utility tunnels. Along with the popularization of the utility tunnel, criss-cross utility tunnel nets can be gradually formed. However, due to the difference of the time of the construction of the pipe gallery, the natural sedimentation of the pipe gallery which is firstly built after one year or more tends to be stable, and the sedimentation amount of the newly-built pipe gallery is difficult to control. How to reduce the uneven settlement of new and old piping lane hookup location becomes the problem that awaits solution urgently. Regarding the connection method of new and old pipe galleries, a method for realizing the connection of pipe galleries by adopting an extensible end well (CN 201710407764.6 a comprehensive pipe gallery extensible end well and a construction method thereof, under the condition that the comprehensive pipe gallery is built in different periods, the problem that the traditional pipe gallery end well cannot be connected with a long-term pipe gallery can be solved. In the aspect of considering the uneven settlement, a fixing structure for preventing the uneven settlement of the pipe gallery joint (CN 202020746908.8 a fixing structure for preventing the uneven settlement of the pipe gallery joint, wherein the fixing structure is arranged at the joint of two pipe gallery sections and comprises a cushion layer and a micro pile, the cushion layer is arranged at the bottom of the joint of the two pipe gallery sections, and the cushion layer limits the lower part of the joint of the two pipe gallery sections to prevent the two pipe gallery sections from settling), and the micro pile is adopted, so that the cost is increased, and the construction is complicated. The cast-in-place pipe gallery is connected through setting up the steel limit waterstop (CN202011355026. X bury formula steel limit waterstop structure and construction method in cast-in-place pipe gallery expansion joint) in the expansion joint department, also does not consider new and old pipe gallery and connects the uneven settlement problem, and does not have reversibility if the waterstop protection is improper, influences water-proof effects.

Adopt machinery to add artificial mode, carry out the earthwork excavation below the piping lane bottom plate of having built. Digging 400mm deep, digging 1000mm inwards from the cross section of the built pipe gallery, digging 1500mm more on two sides of the outer wall of the built pipe gallery to serve as a reserved operation space;
Binding steel bars according to the connecting part of the bottom plates and a reinforcement arrangement diagram of the bottom plate of the newly-built pipe gallery;
After the steel bars are bound, installing templates at the connecting part of the bottom plates and the newly-built pipe gallery bottom plate;
After the templates are installed, welding water-stop steel plates at the connecting positions of the bottom plates and the central line positions of the side walls of the bottom plates of the newly-built pipe gallery, then performing concrete pouring, forming the connecting positions of the bottom plates and the bottom plates of the newly-built pipe gallery into a whole, reserving construction joints at the connecting positions of the bottom plates as same as the bottom plates during concrete pouring, and arranging the construction joints 500mm away from the surfaces of the bottom plates;
step 5, binding of side wall steel bars
Binding steel bars according to the side wall joints and the side wall reinforcement map of the newly-built pipe gallery;
step 6, side wall and top plate template installation
After the steel bars are bound, mounting the side wall joints, the side walls and the top plate templates;
step 7, binding of steel bars of top plate
After the top plate template is installed, binding steel bars at the joint of the top plate and the top plate;
step 8, installing the template at the joint of the top plate
After the steel bars at the joint of the top plate are bound, installing a template;
(9) side wall and top plate concrete pouring
After the formwork is installed, concrete is poured on the side walls and the top plate (including the connecting part) at the same time to form a whole.
According to the invention, the new and old pipe galleries at the joint are integrated by adopting a hard joint mode at the joint of the new and old pipe galleries, so that the purpose of reducing uneven settlement at the joint of the new and old pipe galleries is achieved. Compared with a simple method of arranging a steel-edge water stop belt at a construction joint, the method has the remarkable advantage of reducing uneven settlement. The method is simple and convenient to operate, cost-saving and good in effect, has more obvious advantages compared with a method for arranging the micro-piles at the connecting positions, can be suitable for connecting new and old pipe galleries, and the structure for arranging the micro-piles only aims at the connection of a newly-built pipe gallery.
