therefore, when the worker needs to install the inspection well, the worker finds out the well-installed position, shovels away foreign matters such as soil or stones at the position, shovels away the reserved space capable of accommodating the inspection well, then places the inspection well into the shoveled-away pit position, inserts the joints of the pipelines into the well pipe 2, enables the air bag ring 4 to surround the pipelines, starts the air pump, fills air along the other end of the air inlet 11 through the air pump, enters the expansion cavity 41 along the air inlet 11, increases the air pressure in the expansion cavity 41 along with the increase of the air in the expansion cavity 41, expands the air bag ring 4 under the action of the air pressure, reduces the inner diameter of the expanded air bag ring 4, enables the inner wall of the air bag ring 4 to be tightly abutted against the outer wall of the pipeline along with the action of the inner air pressure, seals the joint of the well pipe 2 and the pipelines through the air bag ring 4, and stops the air pump at the same time, the other end of the air inlet pipe 11 is immediately blocked by a sealing plug to prevent the gas in the expansion cavity 41 from leaking, finally, the well cover 3 is covered on the well body 1, soil or stones are filled outside the well body 1, and then the installation of the building-free inspection well device can be completed, when maintenance is needed, only the well cover 3 needs to be opened, when the building-free inspection well device needs to be replaced, only the sealing plug at the other end of the air inlet pipe 11 needs to be pulled down, the elasticity of the balloon ring 4 can contract per se, so that the gas in the expansion cavity 41 is discharged along the other end of the air inlet pipe 11 under the action of the balloon ring 4, and the purpose of expanding the diameter of the inner wall of the balloon ring 4 can be realized, and the sealing formed by the balloon ring 4 and the pipeline can enable the pipeline to be pulled out of the well pipe 2, namely the disassembly of the building-free inspection well device is completed;
wherein, the air pump can be replaced by the pressure regulating component 5, after the operator pulls the pipeline to the inner side of the sac ring 4 of the well pipe 2, the operator only needs to press the pressurizing block 53 by foot or hand, when the operator needs to pressurize the expansion sac, the pressurizing block 53 slides along the pressurizing groove 52 close to the bottom of the groove, the air in the pressurizing groove 52 is extruded by the pressurizing block 53 to open the second check valve 57 to enter the other end of the air inlet 11, and finally enters the expansion cavity 41 along the air inlet 11, so as to expand the sac ring 4, when the operator releases the pressurizing block 53, the pressurizing block 53 moves along the pressurizing groove 52 away from the bottom of the groove under the action of the spring 54, and forms negative pressure in the moving process, so as to open the first check valve 56 along the air inlet hole 55 to enter the pressurizing groove 52, thereby supplementing the air in the pressurizing groove 52, and then the operator presses the pressurizing block 53 again, the process is repeated, so that the purpose of pressurizing the gas in the expansion cavity 41 is achieved, when the gas in the expansion cavity 41 needs to be depressurized, only the J-shaped rod 59 needs to be pushed to slide along the sliding groove 58, so that the first check valve 56 is poked by one end of the J-shaped rod 59, the second check valve 57 is poked by the other end of the J-shaped rod 59, the air bag ring 4 contracts by self due to the elasticity of the air bag ring 4, the gas in the expansion cavity 41 is pressurized and then discharged along the air inlet 11 and the pressurization groove 52 and finally along the air inlet 55, and the purpose of depressurizing the gas in the expansion cavity 41 is achieved;
the cross section of the sliding chute 58 is round, so that when the inspection well is used, the short end of the J-shaped rod 59 is downward under the action of gravity, and the short end of the J-shaped rod 59 is staggered with the air inlet 55, so that even if the J-shaped rod 59 slides, the two ends of the J-shaped rod 59 cannot contact with the first check valve 56 and the second check valve 57 under the obstruction of the outer wall of the pressurizing block 53, and the first check valve 56 and the second check valve 57 are prevented from being opened due to the fact that foreign matters drive the J-shaped rod 59 to slide, and finally the adverse effect of gas pressure relief of the expansion cavity 41 is caused; when the first check valve 56 and the second check valve 57 need to be opened simultaneously, the purpose of opening the first check valve 56 and the second check valve 57 can be achieved only by rotating the J-shaped rod 59 to enable two ends of the J-shaped rod 59 to be aligned with the first check valve 56 and the second check valve 57 respectively and pushing the J-shaped rod 59 to slide along the sliding groove 58, and the air inlet 55 is blocked by the plug when the well lid 3 is closed at ordinary times;
when one end of the pipeline enters the well pipe 2, the outer wall of the pipeline can be in contact with the elastic sheet 6, and the elastic sheet 6 can scrape the outer wall of the pipeline, so that impurities on the outer wall of the pipeline fall off under the action of scraping; in the process that the pipeline extends into the well pipe 2, the elastic sheet 6 is bent by the outer wall of the pipeline, the balloon ring 4 is expanded through the pressure regulating assembly 5, a part of the expanded balloon ring 4 presses the outer wall of the pipeline through the elastic sheet 6, and after the masonry-free inspection well device is installed, the friction force between the outer wall of the pipeline and the elastic sheet 6 with the anti-skidding strips 61 needs to be overcome when the pipeline is subjected to pulling force; after being bent, the elastic sheet 6 is extruded by the balloon ring 4, so that one surface of the elastic sheet 6 is attached to the outer wall of the pipeline, the other surface of the elastic sheet 6 is attached to the outer wall of the balloon ring 4, and the friction force between the balloon ring 4 and the elastic sheet 6 is increased through the arrangement of the clamping strip 42 and the anti-slip strip 61 on the inner side of the elastic sheet 6; the two well pipes 2 are connected by the bag pipe 7, so that impurities such as sludge and sewage are left in the well body 1 as much as possible.
