Abstract

The invention discloses a sinking-prevention structural body of a well peripheral composite material. The structural body comprises a base and a well lid seat. The base is a table body, wherein the center of the table body is provided with a through hole matched with the well lid, and the base is embedded on the roadbed on the periphery of a well hole of an inspection well. The well lid seat is arranged on the base and is flushed with the road surface. The base is made of concrete composite materials and comprises, by weight, 300 parts to 500 parts of cement, 30 parts to 50 parts of expanding agents, 1500 parts to 2000 parts of aggregate and 8 parts to 10 parts of water reducing agents. According to the sinking-prevention structural body of the well peripheral composite material, the load diffusion area is increased so as to obviously reduce shaft stress, and the phenomena of well periphery sinking and the like caused by damage of a brick body of the shaft are avoided.

Description

technical field

[0001] The invention relates to a building prefabricated component, in particular to a composite material anti-subsidence structure around a well. Background technique

[0002] The inspection well is a well-shaped structure located on the underground pipeline. It is an operating space for checking the operation of the pipeline and dredging. It is used to connect professional pipelines with different elevations, different slopes, different pipe diameters, and different directions. It is an underground pipeline project. Essential municipal facilities. The inspection wells on the motorway mainly include water supply inspection wells, rainwater inspection wells, sewage inspection wells, electric power inspection wells, communication inspection wells, etc. According to the shape of the wellhead, inspection wells are divided into circular inspection wells and rectangular inspection wells. At present, the vast majority of these inspection wells are circular brick ...

Embodiment Construction

[0027] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the present invention provides a composite material anti-subsidence structure around a well, including a base 1 and a well cover seat 13. Set on the subgrade around the wellhead of the inspection well, the manhole cover seat 13 is arranged on the base 1 and is flat with the road surface; in the present invention, the base 1 is made of concrete composite material, and its composition is in parts by weight It includes: 300-500 parts by weight of cement, 30-50 parts by weight of expansion agent, 1500-2000 parts by weight of aggregate and 8-10 parts by weight of water reducing agent. The swelling agent and the water reducer are commercially available conventional products. But preferably, the aggregates include fine aggregates and coarse aggregates, and the weight ratio of the fine aggregates to the co...
