Permeable brick paving ground and construction method

Abstract

The invention provides a permeable brick paving ground. The permeable brick paving ground sequentially comprises a non-sand permeable concrete cushion, a dry-sand leveling layer and a surface layer from an original earth road foundation from bottom to up, wherein the dry-sand leveling layer is a coarse sand layer; the surface layer comprises grid face bricks and permeable bricks in various grid units formed by the grid face bricks in an encircling manner. A construction method of the permeable brick paving ground comprises the following steps: constructing a draining canal in an earth road foundation; constructing the non-sand permeable concrete cushion; paving the grid face bricks to divide a square ground into a plurality of grid units; then vertically building the permeable bricks of the surface layer in the grid units; finally, carrying out dry-sand seam sweeping to compact brick joints. According to the permeable brick paving ground, all the structural layers have the ventilated and permeable function; meanwhile, water seepage on the ground and the draining canal in the ground are combined together to form a perfect ground rainwater drainage and seepage system; when the rain is relatively light, rainwater directly seeps underground through the ground; when the rain is relatively heavy, rainwater is removed by mainly adopting the draining canal, and is assisted by ground water seepage; the permeable brick paving ground is good in effects of water drainage and seepage.

Description

technical field [0001] The invention belongs to the technical field of large-scale square ground engineering construction, and in particular relates to a permeable brick-paved ground and a construction method. Background technique [0002] The brick paving ground of large squares usually uses concrete as the cushion, and then cement mortar is used to lay the brick surface. Usually there are some deficiencies as follows: 1. Rainwater is discharged to drainage pipes or ditches through the slope of the ground, and the way of rainwater discharge is too single. When the rain is heavy, water will often accumulate on the uneven ground; therefore, we need to improve the rainwater drainage system on the ground of the square. 2. With the development of the city and the requirements for environmental protection, the application of permeable ground is becoming more and more extensive. How to make the tiled floor have a good water permeability requires us to study in depth. Convention...

There are usually some disadvantages as follows: 1. The rainwater is discharged to the drainage pipe or ditch through the slope of the ground, and the way of rainwater discharge is too single

Conventional brick-paved ground basically does not have the function of water permeability. First, the ordinary plain concrete cushion directly blocks the penetration of rainwater. Hardening will also seriously affect the penetration of rainwater
