Embodiment 1

[0037] An ecological permeable concrete pavement, including a surface layer, a structural layer, a base layer and a base layer arranged from top to bottom, the structural layer is fly ash ceramsite concrete; the base layer is recycled aggregate; the fly ash ceramsite concrete includes the following weight Raw material composition: 450 parts of cement, 700 parts of fly ash ceramsite, 260 parts of recycled aggregate, 6 parts of water reducing agent, and the balance is water.

[0038]A preparation method of ecological permeable concrete pavement, the fly ash ceramsite concrete is made by the following method:

[0039] S1. Fully soak the fly ash ceramsite, and then air dry for 20 hours;

[0040] S2. Put fly ash ceramsite and recycled aggregate into the mixing device, mix for 2 minutes, add cement, water reducing agent and appropriate amount of water and mix for 2 minutes, and finally add all the remaining water and mix for 4 minutes;

[0041] S3, using a rolling tool for rolling ...

Embodiment 2

[0044] refer to Figure 1-10 , a method for preparing an ecological permeable concrete pavement, the mixing device includes a box body 1, the bottom inner wall of the box body 1 is connected to a chassis 2 through bearing rotation, the top of the chassis 2 is fixed with a mounting rod 3 by bolts, and the top of the installation rod 3 is fixed with a bolt The top plate 4, the top plate 4 is connected with a driving mechanism, a plurality of evenly distributed sleeve rods 11 are hinged on both sides of the installation rod 3, and a filling cavity 20 is opened on the outside of the sleeve rods 11, and an inner rod 12 is arranged in the filling cavity 20. The outside of the rod 12 is fixed with an impact block 18 by bolts, and the inner wall on both sides of the box body 1 is fixed with an impact block 19 by bolts. Both the impact block 18 and the impact block 19 are arranged in a hemispherical shape. Plate 13, the rear end of positioning plate 13 is provided with the first chute ...

Abstract

The invention belongs to the technical field of pavements and particularly relates to an ecological permeable concrete pavement and a preparation method thereof. The ecological permeable concrete pavement comprises a surface layer, a structural layer, a base layer and a base layer which are arranged from top to bottom, wherein the structural layer is made of fly ash ceramsite concrete; the base layer is made of recycled aggregate; the fly ash ceramsite concrete is prepared from the following raw materials in parts, by weight, 450 to 580 parts of cement, 700 to 900 parts of fly ash ceramsite, 260 to 380 parts of recycled aggregate, 6 to 14 parts of a water reducing agent and the balance of water. When the fly ash ceramsite concrete is prepared, raw materials are mixed and stirred through the mixing device, the speed of the sleeve rod is changed in the stirring process, the sleeve rod swings, meanwhile, the inner rod is drawn in the sleeve rod, and therefore overall mixing efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of pavements, in particular to an ecological permeable concrete pavement and a preparation method thereof. Background technique [0002] Permeable concrete is a kind of porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate, and the surface of coarse aggregate is covered with a thin layer of cement paste to bond with each other to form a uniform cavity. Honeycomb structure. On the one hand, in terms of heat absorption and heat storage functions, it is close to the ground covered by natural vegetation, which can adjust the temperature and humidity of urban space and alleviate the urban heat island effect; on the other hand, permeable concrete has good permeability and can effectively reduce Surface runoff and replenishment of groundwater resources will play an important role in improving urban waterlogging caused by frequent rainstorms in our country. It is ...
