Problems solved by technology

Under normal circumstances, poor concrete is often used to pour the base layer, which is simple and rough. Even if the surface layer is made of permeable pavement materials, it is difficult for water to penetrate from the surface layer into the base layer and spread downward through the base layer.
To put it simply, the imperviousness of the base leads to a lot of false permeable pavement, which loses its practical significance

Embodiment Construction

[0013] The present invention will be further explained below in conjunction with application examples.

[0014] The implementation steps of the present invention are as follows:

[0015] Step 1. Process a hollow prism template from wood, bamboo, PVC board or plastic bucket profile;

[0016] Step 2. Place the template evenly and spacedly on the cushion;

[0017] Step 3. Pour the base course with lean concrete or cement stabilized gravel;

[0018] Step 4. Open the top cover of the template, fill gravel to the top of the template to construct a permeable column, and then take out the template;

[0019] Step 5. Spray the infiltration column with emulsified asphalt or cement mortar;

[0020] Step 6. Fill the gaps after removing the template with medium coarse sand.

[0021] In the step 1, the height of the prism template is the same as the set base layer, and the diameter of the circumscribed circle of the horizontal cross section is 20-40 cm; in the step 2, the outer edge of the template is se...

Abstract

The invention provides a porous base layer construction method of a light-load road, and belongs to the field of garden and road engineering road building maintenance. The method is mainly characterized in that wood, bamboo materials, PVC plate materials or rubber barrel materials are processed into hollow prismoid templates; the templates are uniformly fixed and distributed on a pad layer at intervals; lean concrete is used for casting or cement stable clastic rock is used for spreading a base layer; a template top cover is opened; the clastic rock is filled to the top surface of the templates to form a seepage post; then, the templates are taken out; the seepage post is sprayed and coated by emulsified asphalt or cement mortar; gaps after the templates are taken out are filled with medium coarse sand.

Description

Technical field [0001] The invention relates to a construction method for a permeable base layer of a light-load road, belonging to the road construction and maintenance field of gardens and highway engineering. Background technique [0002] Light-load roads are mostly involved in garden engineering, municipal engineering and highway engineering, and are mainly pavement structures for pedestrians. It is generally composed of a surface layer and a base layer, or a cushion layer. This structure is mainly suitable for pedestrian loads, but also compatible with car loads, and has both the need for drainage in rainy days. The current concept of sponge city is gradually gaining popularity among the people, requiring garden trails, non-motorized vehicle lanes of municipal roads, pedestrian passages within red lines, and highway hard shoulder passages to have appropriate "surface penetration and underground water storage" functions. Under normal circumstances, lean concrete is often us...
