Problems solved by technology

However, water still accumulates in the low-lying places caused by the rolling of vehicles on the road surface. Over time, these accumulated water will erode the road surface, causing damage to the road surface and roadbed, which will bring many unfavorable factors to the bearing capacity and service life of the road.

Embodiment 1

[0022] Embodiment 1 of the present invention: a reinforced subgrade pavement for preventing stagnant water, constituted as figure 1 As shown, it includes permeable asphalt pavement layer 1, volcanic ash permeable reinforced road base 2, anti-seepage geotextile water-resisting layer 3 and foundation stone layer 4 arranged in sequence from top to bottom. The anti-seepage geotextile water-resisting layer 3 The upper part is provided with permeable pipes 5 at equal intervals, and several permeable holes 6 are opened on the permeable pipes 5. The pipe head of the permeable pipes 5 is connected with a water delivery pipe 7, and the end of the water delivery pipes 7 that is not connected with the permeable pipes 5 Connected under the water surface, the water surface can be a drainage ditch with water all year round or a rainwater storage tank, etc. Even if it is a drainage ditch that is usually dry, when it rains, the water level of the ditch rises, which can also meet the water level...

Abstract

The invention relates to the technical field of highway construction, in particular to an anti-ponding reinforced roadbed pavement. The structure comprises a water-permeable asphalt pavement layer, avolcanic ash water-permeable reinforced roadbed layer, an anti-seepage geotextile water-resisting layer and a foundation stone layer which are sequentially arranged from top to bottom; permeable pipesare arranged on the upper portion of the anti-seepage geotextile water-resisting layer at equal intervals, a plurality of permeable holes are formed in the permeable pipes, and pipe heads of the permeable pipes are connected with water conveying pipes; the ends, not connected with the permeable pipes, of the water conveying pipes are connected under the water surface, and the water conveying pipes located at the permeable pipe ends are higher than the water surface. According to the reinforced roadbed pavement, accumulated water on the road surface can be reduced, and infiltrated water can be smoothly discharged out of the roadbed, so that the safety of the roadbed and the road surface is guaranteed, and the service lives of the roadbed and the road surface are prolonged.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a waterlogging-proof reinforced roadbed pavement. Background technique [0002] Whether the pavement and the internal drainage of the roadbed are smooth or not directly affects the overall strength of the roadbed and pavement structure, thereby affecting the bearing capacity and service life of the road. The surface drainage of the road surface is mainly to drain the water that falls on the shoulder surface and the road surface, so as to reduce the damage of the road surface water; the traditional roadbed pavement generally adopts the drainage ditch on both sides of the roadbed for drainage. However, water still accumulates in the low-lying places caused by the rolling of vehicles on the road surface. Over time, these accumulated water will erode the road surface, causing damage to the road surface and roadbed, and bringing many unfavorable factors to the road's carryin...
