Asphalt pavement well lid with adjustable base and installation method

Abstract

The invention discloses an asphalt pavement well lid with an adjustable base. The asphalt pavement well lid with the adjustable base comprises a cover body, annular well rings and a base. The base comprises a support base with an annular groove, a top plate arranged on the annular groove and moving up and down relative to the support base, and an elastic support mechanism for connecting the top plate and the support base so as to elastically support the top plate; multiple layers of annular well rings are arranged; the thickness of each layer of annular well ring is prefabricated according tothe thickness of each layer of asphalt; the annular well rings are placed in an annular groove of the support base; the cover body is placed on the annular well rings; and a fastening piece penetratesthrough the cover body, the annular well rings and the top plate so as to fixedly connect the cover body, the annular well rings and the top plate. According to the asphalt pavement well lid with theadjustable base provided by the invention, the well lid in asphalt concrete road construction can be conveniently risen and constructed.

Description

technical field [0001] The invention relates to the technical field of well covers, in particular to an asphalt pavement well cover with an adjustable base and an installation method. Background technique [0002] In the construction of urban asphalt concrete roads, many municipal manhole covers are located in the center of the asphalt road. The traditional method is to temporarily fix the manhole cover under the asphalt layer of the asphalt pavement to be paved, first carry out the asphalt paving construction, and after the asphalt paving is completed, carry out the manhole cover raising well construction. [0003] The construction process of raising the well includes: finding the position of the manhole cover under the asphalt, chiseling off the asphalt covered on the manhole cover, installing the manhole ring skeleton, manhole cover, pouring the manhole ring concrete, and concrete curing. The process is complicated and the cycle is long. Moreover, the following problems ...

Problems solved by technology

[0003] The construction process of the well includes: finding the position of the manhole cover under the asphalt, chiseling off the asphalt covered on the manhole cover, installing the manhole ring skeleton, manhole cover, pouring the manhole ring concrete, and concrete curing. The process is complicated and the cycle is long

Moreover, the following problems occurred during the construction of the well: the position of the manhole cover was not well marked or buried by asphalt, so it was impossible to accurately find out all the manhole covers and their positions, and it was easy to miss; the area of ​​asphalt concrete removed was large, and a large amount of asphalt concrete waste would be produced; The process of raising the well involves cutting out asphalt, installing the well ring and steel fixing frame, pouring the well ring and the concrete around the well cover, and concrete maintenance. The construction period is long and the construction cost is high.
