Description

Technical Field

[0001] The utility model relates to a lining structure, in particular to an inspection well lining structure, belonging to the technical field of inspection wells. Background Art

[0002] Inspection wells are set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines. They are easy to install and are generally located at pipeline intersections, turns, changes in pipe diameter or slope, and at certain intervals on straight pipe sections. Inspection wells are mostly used in building communities (residential areas, public building areas, factory areas, etc.) where buried plastic drainage pipes have an outer diameter of no more than 800mm and a buried depth of no more than 6m. They are well-shaped structures made of plastic one-piece injection molding or bricks for the convenience of regular inspection, cleaning and dredging or downhole operation inspection. As time goes by during the operation of the pipeline, inspection wells often experience leakage and structural corrosion, which eventually causes the inspection well structure to rupture or even collapse, causing safety accidents. Therefore, it is necessary to install an inspection well lining structure inside the inspection well to increase the service life of the inspection well.

[0003] Among them, the inspection well lining structure with application number "CN202223531383.4" is installed on the inspection well wall according to the structural specifications and dimensions of the inspection well. The speed grid pad can be supported in advance with materials such as wooden boards and steel pipes to make the speed grid pad fit the inspection well wall, and then the grouting material is poured into the gap between the speed grid pad and the inspection well wall to fill the gap. When the grouting material solidifies, the speed grid pad can be firmly fixed to the inspection well wall through the anchor key of the speed grid pad to form a lining structure as a whole; because the speed grid pad has good anti-seepage performance and chemical corrosion resistance, the formed lining structure can achieve the purpose of repairing the inspection well. The role of the well wall. Further search found that an inner liner structure for repairing an inspection well with application number "CN200920207862.6" does not require excavation of the ground. The pre-prepared small boiler, hot water tank, air compressor and lining materials for repairing the inner wall of the inspection well can be used to quickly repair and plug the inner wall of the inspection well, which not only saves repair time but also does not pollute the environment, and correspondingly reduces the labor of construction personnel, with low overall cost. The utility model repair method is an inspection well liner structure and its repair method that can be used in conjunction with non-excavation repair of underground pipelines through engineering technology, and the advantages and effects are particularly significant.

[0004] However, the above two types of methods still have certain shortcomings when used. Since the depths of different inspection wells are different, the depths of the inspection well linings required to match are also different, which makes it inconvenient to adjust the depth.
