Construction process for simply plugging outer wall reserved sleeve in underground structure area

Abstract

The invention discloses a construction process for simply plugging an outer wall reserved sleeve in an underground structure area. The construction process comprises the following steps that firstly,an outer wall column and the reserved sleeve in the underground structure area are completed; a handrail and a baffle plate are arranged on the inner side and the outer side of the reserved sleeve respectively, and the handrail on the inner side and the baffle plate on the outer side of the embedded sleeve are fixed through tie rods; after the baffle plate is fixed, a waterproof layer is additionally arranged on the outer side of the baffle plate; and finally, backfilling and tamping of the waterproof protective layer and earthwork layer by layer are conventionally organized. When pipelines are connected inside and outside an underground structure, water stop filler is embedded between the outer wall of a connecting pipe and the inner wall of the sleeve. The problem that mud and rain leakinto an underground structure after earthwork backfilling of a fertilizer tank is solved, and the purposes of facilitating construction, saving materials and reducing labor consumption are achieved.

Description

technical field [0001] The invention relates to a construction technique for simple sealing of reserved casings for outer walls in underground structure areas, in particular to a construction technology for simple sealing of reserved casings for outer walls in underground structure areas. Background technique [0002] With the continuous development of building construction technology, it has become normal to ask for space underground. There are often pipes passing through the outer wall of the underground structure to realize the connection between the inner and outer pipes of the underground structure; however, the installation of the pipes is much later than the earthwork backfilling on the outside of the underground structure. [0003] In order to improve the working environment of the structure construction, usually after the construction of the underground structure is completed, the excavation of the excavation of the excavation of the earthwork of the pipeline trench...

AI Technical Summary

Problems solved by technology

Due to the limitations of concrete or soft materials and other characteristics, it cannot be well combined with the reserved casing, so mud and rain will still leak into the underground structure along the defect between the walls of the reserved casing.
