Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a maintenance device and method of use for road inspection wells and road surfaces around the wells. On the basis of the investigation of pavement diseases around the well, the prefabricated reinforced cement concrete prefabricated structure in the factory, the prefabricated structure is quickly and accurately installed by the hoisting head, and the prefabricated structure and the lower old pavement structure are connected, and the prefabricated structure and Apply or inject modified emulsified asphalt binder at the junction of the old pavement on the side to increase the integrity of the prefabricated structure and the substructure as well as the old and new pavement structures, effectively solving the problem of poor quality and low efficiency of the existing inspection wells and pavement around the wells. question

Embodiment 1

[0045]In a typical embodiment of the present invention, such as Figure 1-Figure 9 As shown, a maintenance device for road inspection wells and pavement around wells is proposed, including: a prefabricated reinforced concrete structure layer 6 (ie, the second structure layer) and a prefabricated fiber composite modified asphalt concrete structure layer 5 (ie, the first a structural layer).

[0046] The reinforced concrete structure layer is a cement concrete structure with continuous reinforcement, which is the main load-bearing part of the vehicle load. The main function of the fiber composite modified asphalt concrete structure layer is to ensure the driving comfort of the inspection well and the road around the well.

[0047] The reinforced concrete structure layer is located at the lower part of the fiber composite modified asphalt concrete structure layer, which are produced in the factory according to the design size, and the two form a prefabricated structure for the ma...

Embodiment 2

[0091] This embodiment proposes a method for using a maintenance device for road inspection wells and road surfaces around the wells, specifically as follows:

[0092] Step 1: Carry out disease range detection on the inspection wells and pavement around the wells that need to be maintained, and provide data support for selecting the size of the assembled structure of the inspection wells and the pavement around the wells;

[0093] Step 2: On the basis of the data obtained in Step 1, prepare prefabricated blocks of road inspection wells and pavement prefabricated structures around the wells with suitable dimensions in the factory and transport them to the construction site;

[0094] Step 3: Use a milling machine to mill the pavement around the well. The milling radius is slightly larger than the radius of the prefabricated block in step 2, so as to facilitate the installation of the prefabricated block;

[0095] Step 4: After the milling is completed, remove the road waste, tri...

Abstract

The invention discloses a maintenance device and method for a road inspection well and a road surface around the well, belongs to the technical field of road engineering road surface maintenance, and can solve the problems that an existing inspection well and the road surface around the well are poor in maintenance quality and low in efficiency through the arrangement of an overall structure. According to the technical scheme, the device comprises a first structural layer and a second structural layer which are adjacently arranged up and down, the first structural layer and the second structural layer are each of an annular structure, a connecting piece is embedded in the top of the second structural layer, the top of the connecting piece is embedded in the first structural layer, and a fastener is fixedly arranged at the top of the connecting piece; and the second structural layer comprises a cylindrical frame structure, and concrete layers are arranged inside and outside the frame structure.

Description

technical field [0001] The invention relates to the technical field of road engineering pavement maintenance, in particular to a maintenance device and method for road inspection wells and pavement around wells. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the construction of urban infrastructure, the urban pipeline network is an important part of the urban infrastructure, and the inspection well is an indispensable part of the urban pipeline network. Due to the difference between the structure of the inspection well and the road structure, the inspection well is prone to settlement. And under the repeated action of vehicle loads, the pavement around the inspection well (referred to as "the pavement around the well") is prone to various diseases such as subsidence and cracking, resulting in poor overall road smoothness and bumpy driving, whic...
