Preparation method of polymer pervious pipe for building sponge city

Abstract

The invention provides a preparation method of a polymer pervious pipe for building a sponge city. The preparation method comprises the following steps: (1) preparing a polymer pervious concrete according to a matching requirement; (2) installing a mold; (3) moving the well installed mold to a vibration platform; (4) casting the prepared polymer pervious concrete into the mold, and feeding while vibrating; (5) moving the well casted pervious pipe and the mold into a steam curing chamber, and using steam for steam-curing, wherein the temperature of water steam is 115 DEG C, and the time for steam curing is 1.5 hours; (6) demolding after completing steam curing, wherein the steam curing lasts for 35 minutes, and the temperature of water steam is 103 DEG C; (7) moving out from the steam curing chamber, and stacking. The polymer pervious concrete has the advantages that half-smooth gaps and closed gaps produced in the forming process of the polymer pervious concrete are reduced, the number of smooth gaps is large, the water permeation is good, and the strength is high; due to the introduction of a polymer, set cement is good in flexibility and deformation resistivity and better in anti-frost property.

Description

technical field [0001] The invention relates to the field of urban drainage systems, in particular to a method for preparing polymer permeable pipes for building sponge cities. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good flexibility in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and releases the stored water when needed, and makes use of it. . At present, the sidewalks and squares of urban roads are mostly paved with permeable bricks or permeable concrete to solve the problem of water seepage and seepage. In order to give concrete a water-permeable function, the original concrete structure needs to change the compactness of the concrete, which greatly affects the frost resistance of permeable bricks or permeable concrete, and the unilateral cost of the product to solve the problem of frost resistance is very high. For example,...
