A new type of water-retaining mud brick

technical field

The utility model belongs to the technical field of building materials, in particular to a novel water-retaining mud brick.

Background technique

There are many rivers in my country, and there are a lot of silt resources in the rivers. At present, large-scale river dredging work is being carried out in most areas. Although the problems of flood control, drainage and navigation of river channels have been solved to a large extent, a large amount of silt generated by dredging has been Dumped into the sea or piled up as waste, resulting in misallocation of resources and damage to the ecological environment.

Most urban drainage mainly depends on the urban drainage pipe network, and severe urban waterlogging is very likely to occur when the rainfall intensity is large, affecting the normal operation of traffic. Most urban squares, commercial streets and other floors are mainly paved with impermeable materials such as cement, granite and marble. When it rains, rainwater cannot pass through the brick body quickly, which is not conducive to the removal of water in the road area, which leads to urban waterlogging and aggravates the city. burden on the drainage system. Even if it is paved with permeable materials, it only promotes the drainage of rainwater in a small amount, and cannot play the role of storing rainwater, nor can it relieve the drainage pressure of the urban drainage pipe network. In addition, although the existing water-retaining bricks have a certain water-retaining capacity, under the conditions of high temperature and dryness, the water is lost rapidly, and the water cannot be continuously added to the atmosphere, which leads to the rapid heating of the road surface and aggravates the urban heat island effect.

Therefore, the rational use of silt to develop new building materials and optimize the brick structure has important practical significance for the utilization of silt and the construction of sponge cities.

The utility model adopts the following technical solutions:

A new type of water-retaining mud brick, comprising a mud-permeable layer (1), an outer layer of mud (2), a water-retention layer (3) and a water storage cavity (4); a protrusion is provided at the bottom of the mud-permeable layer (1) (5), a groove (6) corresponding to the protrusion (5) is provided on the mud outer layer (2); both the mud water permeable layer (1) and the mud outer layer (2) are provided with The longitudinal drainage ditch (7) is provided with permeable holes (8) and a transverse drainage ditch (9) on the outer layer of the silt (2); The holes (8) are connected; the cross-sections of the outer mud layer (2) and the water retaining layer (3) are both U-shaped.

Further, in order to ensure the water permeability effect and strength requirements of the mud permeable layer (1), the thickness of the mud water permeable layer (1) is 1/4-1/3 of the thickness of the water-retaining mud brick.

Further, the water retaining layer (3) is made of superabsorbent resin.

Further, in order to ensure a sufficient volume of the water storage cavity (4), and since the volume of the water storage cavity (4) affects the water storage capacity of the mud brick, the length, width and height of the water storage cavity (4) They are 1/3 of the length, width and height of the water-retaining mud brick.

Further, in order for the water permeable holes provided on the outer mud layer (2) to have sufficient water permeability, the water permeable holes (8) are provided on the outer mud layer (2) every 5-8 cm.

The utility model has the advantages of:

1. The utility model collects rainwater through the water storage cavity and the water-retaining layer, thereby alleviating the pressure of the urban drainage network and reducing the risk of urban waterlogging; after the rainwater is collected and stored in the brick body, it can be gradually dried at high temperature. Evaporate water to the outside to increase air humidity, reduce ambient temperature and alleviate the urban heat island effect.

2. The utility model has simple structure and reasonable design. The river silt is used to make building materials, which better solves the problem of river silt treatment, has good economic benefits, and is suitable for wider application.
