Novel water-permeable brick and pavement construction method thereof

Abstract

The invention discloses a novel water-permeable brick, produced from building waste aggregate, steel slag, Portland cement, pottery sand, machine-made sand, fine clay powder, hollow beads, flyash, a pigment, water and a water reducer. The invention also discloses a pavement construction method of the novel water-permeable brick, comprising the steps of constructing a basic course, constructing a bearing course, tiling water-permeable bricks, cementing joints, maintaining, and clearing a site. The novel water-permeable brick pavement has good drainage and permeability; rain may permeate quickly in the bearing course and permeate directly in underground formations to supplement moisture for the formations, thereby improving growth conditions for surface plants; in addition, the pavement helps relieve the urban 'hot island effect', adjust urban weather, reduce PM2.5 particulate matters in air, prevent pavement ponding, and has good social and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of pavement construction, and in particular relates to a novel permeable brick and a pavement construction method thereof. Background technique [0002] At present, more than 80% of the urban surface is covered by concrete pavements of buildings, and the temperature in urban areas is 2-3 degrees Celsius higher than that in suburban and rural areas, resulting in the so-called "heat island phenomenon". With the advancement of science and technology, human beings have higher and higher requirements for maintaining the harmony between the environment and nature in daily engineering construction. The inability of rainwater to seep into the ground for a long time has brought many social problems to the ecological environment of the city: the groundwater level in the city has dropped, and the replenishment of the underground soil by rainwater has been blocked, thereby affecting the growth of plants on the ground su...

AI Technical Summary

Problems solved by technology

The inability of rainwater to seep into the ground for a long time has brought many social problems to the ecological environment of the city: the groundwater level in the city has dropped, and the replenishment of the underground soil by rainwater has been blocked, thereby affecting the growth of plants on the ground surface, and the urban green area is less, resulting in urban ecology The system is out of balance; the dust increases the PM2.5 particles in the urban air; the excessive rainfall causes the water on the road to seriously block the traffic; etc.
