Problems solved by technology

After the construction is completed, the end materials at both ends of the pipeline need to be cut off, so that about 5 meters of lined hose used for pressurization from the introduction tube for turning over to the bottom of the inspection well on the side of the construction well is cut off and becomes waste, which increases the construction cost
At the same time, the lining hose material needs to be manually turned 90 degrees before being introduced into the pipeline to be repaired during the flipping construction, which wastes time and manpower and increases construction risks
In addition, because the material directly lining the hose doubles as a booster tube, it is impossible to install a water level observation tube at a suitable place, which is inconvenient to check the booster water level when the material is turned over in real time, and the construction process is cumbersome

Embodiment 1

[0059] Such as figure 1As shown, the specific construction process is as follows: After the lining hose material is tied up with the rope pre-passed in the device, it is pulled to the lower opening of the turning cylinder, turned over and fixed on the turning cylinder by straps, and then put the turning cylinder into the After checking the nozzle position of the pipeline to be repaired in the well, add water to pressurize the turning device through the water inlet and outlet pipes. Under the action of 2-3 meters of water pressure, the lining hose material will automatically turn over and enter the pipeline to be repaired until the material is turned over and put into the pipeline to be repaired. The design of the device is reasonable, and it is easier for the lining hose material to enter the pipeline through the turning device, saving costs, and 5 meters of lining hose material can be saved each time. Easy to use, you can add water directly through the water inlet pipe, no n...

Embodiment 2

[0061] Such as image 3 As shown, after using the improved process of the present invention to complete the overturning construction, enter the heating cycle construction, first tie the water pipe of the second water pipeline to the tail of the lining hose material, and complete the construction and layout with the overturning of the lining hose material , secondly, through the second water pipeline connected to the resin hose material, the hot water from the hot water boiler is sent to the reversed lining hose material, and the mixed warm water is pumped out by the hot water pump through the water inlet and outlet Send it to the boiler to continue heating, keep the water pressure of 5 meters in the turning device, and circulate the heating until the lining hose hardens. In the circulation heating process, the hot water pump can be used to directly draw water through the water inlet and outlet pipes, without putting the water pipes into the device from the top to draw water. ...

Abstract

The invention discloses a pipeline non-excavation integral lining repair method. The pipeline non-excavation integral lining repair method relates to CIPP overturning and equipment. The related equipment comprises a lead-in barrel (1), a folding pressurizing sleeve (3), a first water pipeline (5) and a second water pipeline (6), wherein the folding pressurizing sleeve (3) is connected with the lead-in barrel and a turnover barrel (4) in an arc-like shape; one side of the first water pipeline (5) is inserted into the turnover barrel, and the first water pipeline (5) is used for pouring water and turning over a hose material used for a lining; and the second water pipeline (6) is led in from an opening of the lead-in barrel and located in the turnover barrel, and the end of the second water pipeline (6) is connected to the tail of the material subjected to turning over. The pipeline non-excavation integral lining repair method comprises the following steps of S1, pulling in of the hose material used for the lining; S2, turning over of the hose material used for the lining; and S3, hot water curing. By means of the pipeline non-excavation integral lining repair method, on the one hand, the using cost of the lining repair material is reduced, and on the other hand, the automatic turning over requirements of the lining repair material can be met.

Description

technical field [0001] The invention relates to drainage pipes in municipal engineering, in particular to a non-excavation integral lining repair method for pipes. Background technique [0002] Urban drainage pipe network is an indispensable and important infrastructure for modern cities, a basic industry with overall and leading influence on urban economic development, a backbone facility for urban water pollution prevention and control, urban drainage and flood control, and a measure of the level of modern cities. important sign. At present, there are three types of pipeline trenchless repair technology, one is to use resin curing methods to form new drainage pipes inside the pipeline, such as CIPP on-site curing process, etc.; the other is to use small pipes to penetrate large pipes. Small drainage pipes are placed inside the pipes to solve urgent needs, such as short pipe lining, U-shaped pipe dragging and other processes; the last type is to use spiral pipe making to f...
