Problems solved by technology

[0003] However, permeable bricks need to be prefabricated in the factory, and then transported to places where municipal permeable pavement is required for construction. In this process, a series of problems such as factory building system, brick stacking, storage, and transportation are faced, which is not only uneconomical, but also creates More emissions are not environmentally friendly; and the permeable pavement using permeable bricks will make it difficult to improve the strength of the entire pavement material due to the splitness between the permeable bricks and the splitness between the permeable bricks and the sub-base material

preparation example Construction

[0039] Preferably, the pre-coated sand is pre-coated sand treated with a hydrophilic modified resin, which is obtained by stirring the sand, hydrophilic modified resin, curing agent and silane coupling agent, and then pulverizing it. The sand described above is sand with a particle size of 60-80 mesh, and the hydrophilic modified resin is E44 or E51 epoxy resin that has undergone hydrophilic modification through Tween 20 or Tween 80, and the curing agent is selected from the grade It is the aliphatic curing agent of 701, 702, 703 or 593, and the described silane coupling agent is selected from KH550 or KH570 silane coupling agent, and the mass ratio of the described curing agent to the hydrophilic modified resin is 3:10, The mortar-sand ratio is 0.5:100, and the usage amount of the silane coupling agent is 10% of the usage amount of the cementitious material. The preparation method of a kind of four-in-one permeable pavement comprises the following steps:

Embodiment 1

[0049] The four-in-one permeable pavement of the present embodiment, such as figure 1 As shown, it is a continuous integrated structure prepared by sequentially using gravel layer 2, permeable concrete layer 3, permeable mortar layer 4 and resin-based permeable surface layer 5. On-site construction forms.

[0050] In this embodiment, it is preferable to use crushed stones with a particle size of 9.5-19 mm for the crushed stone layer. In this embodiment, the permeable concrete layer preferably adopts a bulk density of 1577kg / m 3 , with an average particle size of 7.4mm and a crushing index of 3.9% basalt. The sand used in the permeable mortar layer in this embodiment is preferably 18-20 mesh single-grade sand, and the cement is Portland 525 cement with a grade of P·I.

[0051] The preparation method of the above-mentioned four-in-one permeable pavement comprises the following steps:

[0052] 1. On the bottom layer of the construction site (such as soil 1), evenly spread a g...

Abstract

The invention relates to a four-in-one water permeable pavement and a preparation method thereof. The four-in-one water permeable pavement is a continuous integrated structure which is formed by usinga crushed-rock layer, a water permeable concrete layer, a water permeable mortar layer and a resin-based water permeable surface layer in sequence; and the resin-based water permeable surface layer is constructed on the surface of the well-molded water permeable mortar layer on site. Compared with the prior art, the four-in-one water permeable pavement has the advantages that problems that the surface layer is cut apart and the surface layer and a base course are cut apart to reduce the strength by using water permeable bricks in a traditional water permeable pavement; a continuous road prepared by using a silica sand material is provided in a revolutionary manner; and meanwhile, a series of economic and environmentally friendly problems, such as workshops, equipment, storage and transportation, needed by preparing traditional water permeable materials are solved.

Description

technical field [0001] The invention relates to the field of "sponge city" permeable pavement, in particular to a four-in-one permeable pavement and a preparation method thereof. Background technique [0002] The advancement of the urbanization process has caused many ecological and environmental problems after the development of the city. Among them, the environmental problem that has the greatest impact on human settlements is the excess hardened road surface. Although cement, concrete, asphalt and other roads are convenient for people to travel, this problem It also directly leads to insufficient water seepage in the city in the face of rainfall, and the insufficient water seepage further causes a series of problems such as urban waterlogging, traffic paralysis, and water pollution. In order to solve such problems, the country proposed the concept of building a "sponge city" in 2012. The so-called "sponge city" requires the city to pay attention to the collection, discha...
