Problems solved by technology

[0002] Existing highways can only rely on the bottom layer for self-seepage, and a lot of water on the surface layer cannot seep into the ground in time
The pavement is soaked by rainwater for a long time, and it is easy to break, resulting in frequent damage to the pavement of the highway. Repeated maintenance will not only affect the opening of traffic, but also increase the cost of maintenance

Embodiment 1

[0016] A construction method for a self-seepage highway. The method includes four steps. The first step is to treat the base soil layer first, and pre-embed a conical seepage cement pipe in the base soil layer, and pre-embed a conical seepage cement pipe per square meter -2, the depth of the conical seepage cement pipe buried in the foundation soil layer is 350-450mm, and the conical water seepage cement pipe buried in the foundation soil layer has a tapered water seepage opening set obliquely downwards, the second step foundation The conical seepage cement pipe with the soil layer upward is connected to the rebar, and the rebar is evenly distributed 4-8 around the circumference of the conical seepage cement pipe, and the concrete is poured. The third step is to lay a 400-800 mesh filter on the top of the seepage cement pipe, and filter The diameter of the net is 200mm larger than the diameter of the upper opening of the conical seepage cement pipe. The fourth step is to lay th...

Embodiment 2

[0020] In the construction method of the self-seepage highway described in embodiment 1, the first step in the first step is to first dig a pit, place the bottom of the conical seepage cement pipe into the pit, and then lay the foundation soil layer with a thickness of 150-200mm compaction, and then lay a cushion layer with a thickness of 150-200mm for compaction. The cushion layer is a mixture of stones and soil, the ratio is 1:2, and the particle size of the stones is 18-20mm.

Embodiment 3

[0022] The construction method of the self-seepage highway described in embodiment 1, the second step of pouring concrete is first pouring concrete around the conical seepage cement pipe, the edge of the concrete is slope-shaped, and is compacted with a vibrating rod. Then lay concrete in a large area, so that the concrete around the conical seepage cement pipe is integrated with the concrete poured afterwards, and then vibrate and compact with a vibrator again, and the concrete thickness is 300-400mm.

Abstract

The invention discloses a construction method of a self-seepage road. An existing road can realize self-seepage through a base course only, and much water on a surface course cannot seep into the ground timely. The construction method is characterized by comprising four steps, firstly, treating a base soil layer and pre-burying conical seepage cement pipes into the base soil layer, wherein 1-2 conical seepage cement pipes are pre-buried in every square meter area, the conical seepage cement pipes are buried in the base soil layer by depths of 350-450mm, and the conical seepage cement pipes buried in the base soil layer have conical seepage ports which are arranged downwards obliquely; secondly, connecting deformed steel bars to the conical seepage cement pipes which face upwards on the base soil layer, and pouring concrete; thirdly, paving a filter screen of 400-800 meshes at the tops of the seepage cement pipes; fourthly, paving a surface course, wherein the seepage cement pipes are 10-20mm lower than the upper surface of the surface course, and 6-10 deformed steel bars which are distributed at different heights are connected to the conical seepage cement pipes on the section. The construction method disclosed by the invention is used for building roads.

Description

Technical field: [0001] The invention relates to a construction method of a self-seepage road. Background technique: [0002] Existing highways can only rely on the bottom layer for self-seepage, and a lot of water on the surface layer cannot seep into the ground in time. The pavement is soaked by rainwater for a long time, and it is easy to break, causing frequent damage to the pavement of the highway. Repeated maintenance not only affects the opening to traffic, but also increases the cost of maintenance. Invention content: [0003] The purpose of the present invention is to provide a self-seepage highway construction method that can well make the rainwater on the road surface penetrate into the ground and ensure that the road surface will not be soaked by rainwater. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A construction method for a self-seepage road, characterized in that: the method includes four steps, the first step is to ...
