[0035] b. Preparation of modified absorbent cotton filling block:

[0036] b 1 . Put the absorbent cotton in the cement mortar and soak it, so that the cement mortar fully soaks the absorbent cotton, and obtains the cement mortar soaked absorbent cotton. Specifically, the cement mortar consists of cement, fine sand and water, wherein the mass ratio of cement to fine sand is 1: (1-3), and the particle size of the fine sand is optimally 60-100 mesh. The cement mortar The consistency is 10-20, so that the cement mortar can enter the pore structure of the absorbent cotton, so that the absorbent cotton can harden and have a certain supporting strength.

[0037] b 2 . Soak the cement mortar with absorbent cotton and dry until hardened. For example, the absorbent cotton is soaked in cement mortar for 10-48 hours, then taken out, drained and dried naturally until the cement mortar in the absorbent cotton solidifies and hardens.

Embodiment 1

[0051] Cement is used as an adhesive, a mixture of coarse sand, fly ash, and crushed construction waste is used as a supporting aggregate, and a foaming agent is used as a pore-forming agent to form a permeable skeleton 100 by using a mold. The thickness ratio of the bottom, water-retaining part and top of the permeable skeleton is 1:1:1. A large water-retaining chamber is set in the water-retaining part, and the water-retaining chamber is filled with modified absorbent cotton filling blocks. The modified absorbent cotton filling block is prepared by the following method: the waste sponge is placed in cement mortar and soaked for 48 hours, so that the cement mortar fully soaks the waste sponge to obtain the cement mortar soaked absorbent cotton; the cement mortar soaked absorbent cotton is naturally drained, Naturally dry until the cement mortar is solidified; according to the shape and size of the water-retaining chamber, the hardened cement mortar is infiltrated with water-ab...

Embodiment 2

[0053] Cement is used as an adhesive, a mixture of coarse sand, fly ash, and crushed construction waste is used as a supporting aggregate, and a foaming agent is used as a pore-forming agent to form a permeable skeleton 100 by using a mold. The thickness ratio of the bottom, water-retaining part and top of the permeable skeleton is 1:2:2. A large water-retaining chamber is set in the water-retaining part, and the water-retaining chamber is filled with modified absorbent cotton filling blocks. The preparation method of the modified absorbent cotton filling block is the same as that in Example 1.

Abstract

The invention provides a water permeable brick and a preparation method thereof, and belongs to the technical field of sponge cities. The water permeable brick comprises a water permeable skeleton anda water-retaining lining, wherein the water permeable skeleton is formed by pressing water permeable aggregate, the water-retaining lining is wrapped by the water permeable skeleton, the water-retaining lining is made of modified water-absorbing cotton, and the modified water-absorbing cotton is water-absorbing sponge fully infiltrated with cement mortar. The water-retaining lining and the waterpermeable framework are connected into a whole, the hollow sign does not exist, and the strength of the water permeable brick is guaranteed. The water-absorbing sponge maintains most of the water-absorbing and water-permeable performances, so that the water-permeable brick has a strong water-retaining function. According to the water-retaining lining made of the modified water-absorbing cotton, inthe rainwater absorption and release process, the macrostructure of the water-retaining lining cannot be changed or is difficult to change, so that the service lifetime of the water permeable brick is effectively prolonged, and the duration time of the water-retaining function of the water permeable brick is prolonged. Meanwhile, due to the characteristics of the modified water-absorbing cotton,the water permeable brick is endowed with good moisture retention, noise reduction and sound absorption properties and warm-keeping and cold-resisting properties.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and in particular relates to a permeable brick and a preparation method thereof. Background technique [0002] Permeable bricks refer to a type of ground paving material that has a high porosity of the bricks and rainwater can penetrate into the ground through the bricks. As an important part of sponge city construction, permeable bricks can absorb, store, infiltrate, and purify rainwater, which is of great significance for alleviating the pressure of urban flood discharge, reducing the phenomenon of rainwater overflow, and changing the local environment and climate. [0003] With the innovation and progress of technology, permeable bricks have been endowed with multiple functions, such as attaching photocatalysts on the surface of permeable bricks to realize self-cleaning of permeable bricks, changing the material of permeable bricks to enhance the strength of permeable bricks. The Chines...
