Embodiment Construction

[0036] The present invention will be further described below in conjunction with the examples. The description of the following examples is provided only to aid the understanding of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0037] refer to figure 1 As shown, the composite repair construction of the inspection well with in-situ pouring lining includes the following construction steps:

[0038] 1) Construction preparation: remove debris from inspection well shaft 1, water delivery pipe 2 and inspection well foundation 61, and prepare devices and materials required for construction;

[0039] 2) Setting of water pipe sealing pockets: set a water pipe sealing pocket 3 in the water deliv...

Abstract

The invention relates to a composite restoration construction method of in-situ pouring lining of an inspection well, comprising the steps of: 1) construction preparation; 2) setting of a water pipe sealing bag; 3) lifting support frame support; 4) spraying and scouring of the inspection well shaft; Inner lining layer spraying and repairing construction; 6) Inner lining layer steam pressurized curing. The beneficial effect of the present invention is that: the present invention respectively sets a water pipe sealing bag in the water delivery pipe on both sides of the inspection well shaft, and can apply a lateral jacking force to the two water pipe sealing bags synchronously through the transverse brace ribs, reducing the water delivery. The efficiency and difficulty of water pipe sealing construction; the invention can control the height of the water spray ring pipe by lifting the boom, and can use the water filtration recovery tank to synchronously recover the residual water during the construction of the wellbore flushing of the inspection well, and use the water filter support plate to filter and inspect The solid particles produced in the flushing construction of the well shaft improve the efficiency of the flushing construction of the inspection well shaft and prevent the flushing water from polluting the water delivery pipe.

Description

technical field [0001] The invention relates to a composite restoration construction method for in-situ pouring lining of an inspection well, which can improve the effect of spraying water on the shaft of the inspection well, improve the construction quality and efficiency of the inner lining layer, and protect the construction environment, and is suitable for inspection wells in municipal engineering or water conservancy projects Maintenance works. Background technique [0002] During the operation and use of inspection wells, due to the influence of factors such as high humidity and high temperature stress in water pipes, the inner lining of inspection wells often breaks and falls off. [0003] In the prior art, there is a field-formed inspection well lining repair structure and method. The repaired inspection well has a structure of "old inspection well + lined inspection well", and the "lined inspection well" is still deformed. It can independently bear various loads; t...
