Embodiment Construction

[0042] Below in conjunction with embodiment the present invention is further described.

[0043] As shown in the attached figure, it is a cast-in-place guide hole permeable concrete. The guide hole permeable concrete is composed of a guide hole permeable structure layer and a porous water permeable surface layer. A permeable guide hole is made in the guide hole permeable structure layer, and the guide hole is permeable. The structural layer accounts for 80-90% of the pavement thickness. The permeable structure layer of the guide hole permeable concrete adopts the method of artificial guide holes, which eliminates the generation of invalid pores, the size of the pores and the distribution of pores can be adjusted freely and has little effect on the strength, which solves the incompatibility between the strength and water permeability of traditional permeable concrete The problem.

Abstract

The invention discloses cast-in-place perforated pervious concrete and a preparation device and process thereof, and belongs to the technical field of construction of a cast-in-place pervious concretepavement. The cast-in-place perforated pervious concrete consists of a perforated pervious structural layer and a porous pervious surface layer. The preparation device is a drivable preparation device body mainly composed of a pore-forming device, a support system and a walking system. The preparation process of the cast-in-place perforated pervious concrete pavement includes the preparation of the perforated pervious structural layer and the preparation of the porous pervious surface layer. The cast-in-place perforated concrete produced by the invention can be used for laying sidewalks, bicycle lanes, community grounds, garden landscape grounds, city squares, swimming pools and stadium grounds for the driving of non-motor vehicles, and can be used for laying outdoor parking lots and light and heavy roads for the driving of motor vehicles. The problem of incompatibility between traditional pervious concrete strength and water permeability is completely solved.

Description

technical field [0001] The invention relates to a guide hole permeable concrete and a preparation device, which is especially suitable for the construction of cast-in-place permeable concrete pavement. Background technique [0002] At present, with the acceleration of urbanization, the number of concrete pavements is also increasing. While bringing convenience to travel, it also brings a series of problems such as: (1) urban waterlogging is prone to occur; (2) groundwater cannot Get timely replenishment, leading to the drop of groundwater level; (3) produce "heat island effect" and so on. In order to solve the above problems, my country vigorously promotes the construction of sponge cities. The traditional permeable concrete pavement still has two main problems of low strength and poor water permeability, which are one of the main factors restricting the development of sponge cities. Contents of the invention [0003] In order to overcome the deficiencies of the above-me...
