Problems solved by technology

[0002] Through the investigation and analysis of the urban road drainage system, it is found that the direct paving of asphalt concrete pavement or cement concrete pavement on the ordinary road surface is due to inaccurate control of the elevation of the rainwater outlet, poor road surface smoothness, and non-standard construction of the longitudinal slope of the road. It often leads to the occurrence of pavement water phenomenon. Due to poor drainage of asphalt concrete pavement, subsidence, cracking, loosening and potholes will occur; and as water continuously infiltrates into the pavement surface from cracks, the adhesion of asphalt decreases and blocks The mutual bonding of asphalt and aggregate further damages the integrity of the structure, cannot guarantee the sufficient strength and stability of the road surface, shortens the service life of the road, and brings a lot of inconvenience to traffic after rain

Embodiment Construction

[0021] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a PP-R water supply pipe 1, on which several through holes are arranged at intervals of several distances, on the water supply pipe 1 is wound a gauze 2 for blocking the through holes, and poured a water-permeable structure outside the gauze 2. Concrete 3; the permeable concrete 3 is made by mixing cement and crushed stone, wherein the mass ratio of cement and crushed stone is 1:7, and the particle size of crushed stone is 5-10mm; Three through holes are evenly arranged, and the diameter of the through holes is 5 mm.

[0022] (1) Construction procedures for seepage blind ditches at the edge of urban roads:

[0023] Drilling holes for PP-R water supply pipes → fixing gauze with wire ties → cutting grooves in the asphalt bottom layer → installing seepage pipes → pouring permeable concrete → curing → asphalt top layer.

[0024] (2) Working principle of components

Abstract

The invention relates to the technical field of city road construction, in particular to a city road edge pervious ditch and a construction method thereof. The city road edge pervious ditch comprises a PP-R feed pipe and is characterized in that a plurality of through holes are formed in the feed pipe every other certain distance, the feed pipe is wound by a gauze used for blocking the through holes, and pervious concrete is poured outside the gauze. According to the city road edge pervious ditch and the construction method thereof, operation steps are simple, materials for use are easy to purchase, cost is low, the city road edge pervious ditch is particularly suitable for being used in engineering with low terrain, small longitudinal slopes and high requirements for road surface draining, accumulated water on the edge of the road surface can be rapidly and effectively drained into a rainwater opening, and therefore the water accumulating rate of the road is greatly reduced.

Description

(1) Technical field [0001] The invention relates to the technical field of urban road construction, in particular to a seepage blind ditch at the edge of an urban road and a construction method thereof. (2) Background technology [0002] Through the investigation and analysis of the urban road drainage system, it is found that the direct paving of asphalt concrete pavement or cement concrete pavement on ordinary pavement is due to the inaccurate control of the elevation of the gullies, the poor flatness of the road surface, and the non-standard construction of the longitudinal slope of the road. It often leads to the occurrence of pavement water phenomenon. Due to poor drainage of asphalt concrete pavement, subsidence, cracking, looseness and potholes will occur; and as water continuously infiltrates into the pavement surface from cracks, the adhesion of asphalt decreases and blocks The mutual bonding of asphalt and aggregate further damages the integrity of the structure, c...
