Embodiment 1

[0029] A method for repairing urban groundwater drainage pipe network, the operation steps of the method are as follows,

[0030] S1. Prepare for the repair of the groundwater drainage network, determine the location of the repaired groundwater drainage network, measure the repaired pipeline, measure data and repair requirements;

[0031] S2. Clean the groundwater drainage network, drain the sewage in the groundwater drainage network, and clean up the silt in the groundwater drainage network to meet the repair requirements;

[0032] S3. Laying of repair materials, first lay a layer of plastic film on the bottom of the pipeline to be repaired, and then put the repair lining material in place by mechanical traction;

[0033] S4. The repair material is cured. Install ultraviolet curing equipment at the mouth of the repair lining material and inflate the lining pipe so that it is close to the pipeline to be repaired. The ultraviolet curing equipment irradiates the lining pipe to c...

Embodiment 2

[0037] On the basis of Example 1, the preparation for the repair of the S1 groundwater drainage pipe network uses the urban underground drainage pipe network detection device before the repair to detect the smoothness of the repaired groundwater drainage pipe network on the spot and prepare the size of the repair materials. Fully understand the situation of the damaged pipeline before repairing, and formulate a comprehensive plan.

Embodiment 3

[0039] On the basis of Example 1, the S2 groundwater drainage pipe network is cleaned, and the water blocking air bag is used to temporarily block the drainage upstream of the repair pipe, and then the high-pressure water gun provided on the urban underground drainage pipe network detection device is used to detect the wellhead from the upstream. Entering and moving to the downstream detection wellhead and cleaning repeatedly until the pipeline meets the repair requirements, the pipe wall can be clean and clean, and there will be no sewage to affect the repair process.

Abstract

The invention relates to the technical field of drainage, and in particular relates to an urban groundwater drainage pipe network repair method which comprises the following operation steps of draining sewage in a groundwater drainage pipe network, and clearly cleaning sludge in the groundwater drainage pipe network to reach the repair requirement; laying a layer of mulching film on the bottom ofa pipeline to be repaired firstly, and then enabling a repair lining material to be in place by adopting a mechanical dragging manner; mounting ultraviolet curing equipment at a pipe mouth of the repair lining material, performing inflation on a lining pipe to enable the lining pipe to cling to the pipeline to be repaired, and illuminating the lining pipe with the ultraviolet curing equipment to enable the lining pipe to be cured to form a new pipeline; cutting a tying head of the pipe mouth with a cutting tool, and performing mouth plastering and edge sealing with rapid hardening cement; anddisassembling a water blockage air bag, and putting the pipeline into water passing use. The urban groundwater drainage pipe network repair method can realize that a great quantity of excavated groundis avoided during groundwater drainage pipe network repair, improves the working efficiency of repairing the pipeline and saves the cost.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a method for repairing urban groundwater drainage pipe networks. Background technique [0002] Various pipelines buried under the road are indispensable infrastructure in our life. Due to the vibration of vehicles on the road, the poor foundation of the pipeline itself, and the influence of corrosive sewage and harmful gases, underground pipelines will have cracks, damage, dislocation of pipe joints and corrosion in pipes, and timely repairs are required to avoid road subsidence. It will cause harm to traffic safety and the life and property of citizens. If the damaged pipeline is repaired by the general excavation construction method, it is necessary to excavate a large area of ​​the road. Such a construction method has a long construction period, will generate a large amount of waste, and has a great impact on road traffic, which is harmful to our living env...
