Novel municipal inspection well structure and construction method

Abstract

The invention belongs to the technical field of municipal engineering, and specifically relates to a novel municipal inspection well structure and a construction method. The novel municipal inspectionwell structure composed of a prefabricated pitshaft, a manhole cover, a base course reinforcement layer, a force holding well ring, color steel fiber concrete and the like, wherein the base course reinforcement layer is located on the periphery of the prefabricated pitshaft and at the bottom of a road base course at the same time; and the force holding well ring is inlaid in the road base course,the manhole cover is fixed to the force holding well ring, and the color steel fiber concrete is arranged on the periphery of the manhole cover with the same color as the road surface. According to the novel municipal inspection well structure and the construction method, intensity on the periphery of an inspection well is improved, the construction efficiency, quality and durability of the inspection well are improved, the accuracy of the mounting height of the well ring is realized, and unification of the color on the periphery of the manhole cover and the color of a road surface structureis realized.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to a novel municipal inspection well structure and a construction method. Background technique [0002] As an important part of municipal pipeline engineering, urban road inspection well is also the difficulty and focus of municipal engineering quality control. Under the repeated action of vehicle loads on urban road inspection wells, the road surface will be damaged to varying degrees related to the inspection well, such as the sinking of the inspection well cover, cracks and damage in the asphalt layer around the well, etc., requiring frequent maintenance, which is a waste of time and money. A waste of manpower affects urban traffic order.

Problems solved by technology

Under the repeated action of vehicle loads on urban road inspection wells, the road surface will be damaged to varying degrees related to the inspection well, such as the sinking of the inspection well cover, cracks and damage in the asphalt layer around the well, etc., requiring frequent maintenance, which is a waste of time and money. Waste of manpower, affecting urban traffic order

[0003] Aiming at the traditional municipal inspection well construction technology, the Chinese patent with application number 201710846639.5 titled "A Municipal Road Heavy Manhole Cover Well Circle Reinforcement Structure and Its Construction Method" discloses a inspection well reinforcement process of prefabricating the well circle at the top of the wellbore. The wellbore of this method is a traditional brick structure, and the durability of the wellbore is poor; the contact surface of the prefabricated well circle and the concrete is an inclined plane, and the two are prone to relative displacement, and at the same time, the concrete will be pulled and cracked; within the scope of the subgrade The periphery of the wellbore is backfilled with graded sand and gravel, and the plate quality of the graded sand and gravel is not as good as that of cement stabilized aggregates. In addition, the low-density polyethylene foam board is a flexible structure. After the road surface receives vehicle loads, the inspection well structure will produce vertical strain. After a long time, the asphalt surface layer will produce fatigue damage and cracks, which will affect the durability of the structure; the Chinese patent application number 201720144293.X, titled "A Reinforced Inspection Well", discloses a method of pouring plain concrete around the wellbore to strengthen the inspection well. Well technology, this method is one-time pouring of plain concrete, which affects the regular paving of the base

In addition, the bottom of the plain concrete is located on the soil roadbed, and after being impacted by the vehicle load for a long time, it will partially settle, and then cause defects such as road surface damage
