Problems solved by technology
[0004] Based on the technical problems existing in the background technology, the present invention proposes a drainage type municipal road and its construction method, which has the characteristics of avoiding the blockage of the drainage pipe and ensuring the normal drainage of the road, and solves the problem that the existing drainage type municipal road cannot avoid the blockage of the drainage pipe. Therefore, the problem of normal drainage of the road cannot be guaranteed

Embodiment 1
[0023] Earthwork works first, and when there is filling on the top of the soil subgrade, it will be constructed at the same time as the pipeline project to reduce the amount of earthwork excavation, and then the pipeline project will be excavated, the foundation will be treated, the pipe will be lowered, the pipe foundation will be poured, and the inspection well will be built locally. Backfilling, closed water test, all backfilling, then construction of the road subbase, excavation after completion, construction of rainwater connection pipes, installation of curbs at the same time, then base construction, and finally pavement construction, sidewalk construction at the same time as base and pavement construction , Install flow meters and alarms and other equipment after the construction is completed.
Embodiment 2
[0025] In embodiment one, add following operation:
[0026] After the construction of the mixture is completed, it should be maintained in time to maintain a certain humidity. It should not be too dry or too wet. The curing period should not be less than 7 days, and it should be covered with geotextiles.
[0027] Earthwork works first, and when there is filling on the top of the soil subgrade, it will be constructed at the same time as the pipeline project to reduce the amount of earthwork excavation, and then the pipeline project will be excavated, the foundation will be treated, the pipe will be lowered, the pipe foundation will be poured, and the inspection well will be built locally. Backfilling, closed water test, all backfilling, then construction of the road subbase, excavation after completion, construction of rainwater connection pipes, installation of curbs at the same time, then base construction, and finally pavement construction, sidewalk construction at the same t...
Embodiment 3
[0029] In embodiment two, add following operation:
[0030] When rolling the subgrade, follow the principle of "light first and then heavy, first edge and then middle, first slow and then fast".
[0031] Earthwork works first, and when there is filling on the top of the soil subgrade, it will be constructed at the same time as the pipeline project to reduce the amount of earthwork excavation, and then the pipeline project will be excavated, the foundation will be treated, the pipe will be lowered, the pipe foundation will be poured, and the inspection well will be built locally. Backfilling, closed water test, all backfilling, then construction of the road subbase, excavation after completion, construction of rainwater connection pipes, installation of curbs at the same time, then base construction, and finally pavement construction, sidewalk construction at the same time as base and pavement construction , After the construction is completed, install flowmeters, alarms and ot...

Abstract
The invention discloses a drainage type municipal road and a construction method thereof, comprising a roadbed, a cushion layer is laid on the top of the roadbed, a base layer is laid on the top of the cushion layer, a surface layer is laid on the top of the base layer, the The top of the surface layer is laid with an asphalt layer, and the inside of the roadbed, cushion, base layer, surface layer and asphalt layer is provided with a drainpipe, and the top of the drainpipe is equipped with a cover plate, and the surface of the inner wall of the cover plate is fixedly connected There is a filter plate, the surface of the inner wall of the cover plate is fixedly connected with a flow meter at the bottom of the filter plate, a sundry collection tank is reserved inside the asphalt layer and at the position corresponding to the drain pipe, and the inner wall of the sundry collection tank is The bottom is fixedly connected with a pressure sensor. The present invention solves the problem that existing drainage-type municipal roads cannot avoid drainage pipe blockage and thus cannot ensure normal drainage of the road through the cooperation of filter plates, flow meters, sundry collection tanks, pressure sensors and alarms.
Description
technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a drainage type municipal road and a construction method thereof. Background technique [0002] Pavement refers to one or more layers of road structure paved on the top surface of the roadbed with road construction materials for vehicles to drive directly on its surface. Regardless of whether it is concrete or asphalt pavement, various damages, deformations and other defects will appear one after another after it has been opened to traffic for a period of time. These are collectively referred to as pavement diseases. After cracks appear on the asphalt pavement, the pavement will seep underwater and soak the pavement structural layer, reducing the bearing capacity of the pavement. On the one hand, the water reduces the adhesion of asphalt, which leads to the reduction of the strength and stiffness of the asphalt mixture, and makes the asphalt peel off from the aggre...
