Abstract

The invention relates to a municipal inspection well and a back excavation construction method thereof. The municipal inspection well is composed of a well cover, a well seat and a well barrel. The municipal inspection well is located in a road face structural layer, the road face structural layer comprises a road face bottom base layer and a road face compaction structure which are arranged from bottom to top sequentially. A ring beam is arranged on the well barrel, the bottom of the well seat is fixed to the ring beam through an expansion bolt, and the well cover is arranged on the well seat; concrete is poured between the inspection well and the road face compaction structure as well as between the inspection well and the road face bottom base layer, a rebar framework is pre-buried in the concrete at the ring beam, a glass fiber soil engineering grid layer and an asphalt concrete layer are arranged above the concrete and the road face compaction structure from bottom to top sequentially, the asphalt concrete layer is flush with the upper surface of the well cover, and the bottom of the concrete is 50-55 cm deeper than the bottom of the road face bottom base layer. The municipal inspection well has the characteristics of being safe, suitable and the like, has good popularized and practical values, and can produce good economic benefits after being widely applied and promoted.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and relates to inspection wells on roads, in particular to a municipal inspection well and a reverse excavation construction method thereof. Background technique [0002] With the continuous development of urban roads, the maintenance pipe enclosure of inspection well covers on the road is becoming more and more prominent. Traffic safety accidents caused by cracking and damage between the well cover and the road surface are not uncommon due to the displacement and damage of the manhole cover. At present, the existing problems in the prior art are as follows: 1. The conflict between rigidity and softness around the shaft is relatively large, and the phenomenon of protrusion of the shaft or subsidence around the shaft is obvious. 2. The side of the shaft is subjected to uneven earth pressure for a long time, and the masonry shaft is easily broken. 3. The cost of using a prefabricated shaft is r...
