Asphalt Pavement Inspection Well Masher Construction Method

Abstract

The invention discloses a well raising construction method for an asphalt pavement inspection well acted to an asphalt pavement. The asphalt pavement comprises a pavement and a roadbed. The method comprises the following steps: setting a prefabricated well; preventing deviation of a temporary well lid; paving an intermediate layer; passing through a well raising space; putting an adjustable hanging mold system; preparing a well raising ring; mounting a steel well seat; and mounting the well lid. According to the well raising construction method for the asphalt pavement inspection well disclosed by the invention, a deviation-preventing technology of the temporary well lid is matched with the adjustable hanging mold technology, so that defects of conventional well raising construction methods are avoided, the construction efficiency is improved, and the method has relatively good economic and technological benefits.

Description

technical field [0001] The invention relates to the field of municipal road construction, in particular to a construction method for raising an inspection well on an asphalt pavement. The construction method for raising a well for an inspection well combines a temporary manhole cover anti-deflection technology and an adjustable hanging formwork technology. Background technique [0002] Today, when environmental protection has become a global concern, asphalt pavement projects are being carried out on urban roads in my country. Asphalt pavement has the advantages of dust prevention, pollution-free, noise reduction, and beautiful appearance, so it is loved by the majority of city builders and people. However, another major feature of urban roads is that there are many underground pipelines, which has led to a rapid increase in the number of road inspection wells, especially for rainwater and sewage inspection wells on the roadway or power and telecommunications inspection wells...

Problems solved by technology

However, another major feature of urban roads is that there are many underground pipelines, which has led to a rapid increase in the number of road inspection wells, especially for rainwater and sewage inspection wells on the roadway or power and telecommunications inspection wells in residential areas. Many, these inspection wells are indispensable for urban municipal infrastructure, but also become a difficult point when laying asphalt pavement

[0003] With the development of transportation, the increase of motor vehicles has increased the rolling of inspection wells on asphalt roads. However, the asphalt pavement has the characteristics of insufficient compaction, which leads to the repeated action of vehicle loads on the inspection wells on asphalt roads. Under the repeated action of rainwater, there are common diseases such as falling, damage around the well, and shifting, which will cause water infiltration on the road surface and repeated quality problems.

However, the decline of these inspection wells will bring many problems. First, it will affect the appearance of the urban road surface. The depression of the inspection wells will cause potholes on the road surface. Second, it will affect the driving comfort. When the owner drives the vehicle through the inspection of the drop When the well is in the well, it will suddenly sink and affect the driving comfort, and may even cause a safety accident

For example, when the depression of some inspection wells is serious, it may cause the vehicle tires to slip or sink, which will cause immeasurable safety accidents. Third, it will cause quality problems of underground pipelines. When the inspection well is sunken or damaged, at this time Moisture or other substances on the road surface will enter the underground pipeline, thereby oxidizing or corroding the underground pipeline, and sometimes the substance directly enters the underground pipeline from the side gap, causing safety problems for the underground pipeline, and fourthly affecting the stability of the pavement structure

[0004] However, the traditional Masui construction method has many problems such as low construction efficiency, low installation accuracy, and high economic cost. That is to say, the traditional Masui construction method leads to a long Masui project period due to construction problems, which affects the normal operation of the road surface, and has low safety accuracy.
