And step S2, placing a plurality of building blocks in parallel in the groove after the impermeable membrane is paved.
Specifically, referring to fig. 3, a plurality of blocks are placed along the length direction of the infiltration pipe 2 in the groove after the impermeable membrane is laid, and the number of the blocks is matched with the length of the infiltration pipe 2. The bodies 1 of all the building blocks are arranged in parallel and are sequentially arranged, the bodies 1 of any two adjacent building blocks are in close contact, and the grooves of all the building blocks correspond to form a whole groove matched with the length of the infiltration pipe 2.
And step S3, placing the infiltration pipe in the groove of each building block.
Specifically, since the blocks are arranged in parallel, the grooves 11 of the body 1 of each block are also arranged in parallel, and the infiltration pipe 2 is arranged in the groove 11 of each block body 1, namely each block is arranged at the bottom of the infiltration pipe 2.
Step S4, a plurality of building blocks are buckled on the top of the infiltration pipe, and the building blocks on the top of the infiltration pipe are fixed with the building blocks on the bottom of the infiltration pipe; the groove of the building block at the top of the infiltration pipe corresponds to the groove of the building block at the bottom of the infiltration pipe to form a space for accommodating the infiltration pipe.
Specifically, referring to fig. 3, a plurality of blocks are buckled at the top of the infiltration pipe 2, and the number of the blocks at the top of the infiltration pipe 2 is matched with the length of the infiltration pipe 2, i.e. the number of the blocks at the top of the infiltration pipe 2 is the same as the number of the blocks at the bottom of the infiltration pipe 2. The building blocks at the top of the infiltration pipe 2 are arranged in parallel and are arranged in sequence, and the bodies 1 of any two adjacent building blocks at the top of the infiltration pipe 2 are in close contact with each other. Then, ooze 2 top building blocks of pipe and ooze 2 bottom building blocks and be the one-to-one and set up relatively, ooze the body top of 2 top building blocks of pipe and ooze the body top of 2 bottom building blocks of pipe and dock relatively to, the body top of 2 top building blocks of oozing pipe and ooze the body top accessible cement mortar of 2 bottom building blocks of pipe step mutually and dock. The position of the groove 11 of the body of the block at the top of the infiltration pipe 2 corresponds to the position of the groove 11 of the body of the block at the bottom of the infiltration pipe 2, and the groove 11 of the body of the block at the top of the infiltration pipe 2 and the groove 11 of the body of the block at the bottom of the infiltration pipe 2 are butted to form a plurality of accommodating spaces 3, each accommodating space 3 is sequentially arranged to form a whole accommodating space, and the infiltration pipe 2 is arranged in the accommodating space 3.
In this embodiment, the infiltration pipe 2 is circular, the groove 11 of the block body is semicircular, the accommodating space 3 is circular, and the diameter of the accommodating space 3 is slightly larger than that of the infiltration pipe 2.
In this embodiment, the cement mortar for bonding the top of the body of the top block of the infiltration pipe 2 and the top of the body of the bottom block of the infiltration pipe 2 is M7.5 cement mortar.
Step S5, backfilling is performed around the block.
And particularly, gravel backfilling is carried out on two sides and the periphery of each building block, and planting soil backfilling is carried out above each building block on the top of the infiltration pipe 2.
It can be seen that, in this embodiment, through the top at the infiltration pipe and the bottom equipartition building block, the predetermined compressive strength of building block can protect the infiltration pipe effectively, avoid the damage of infiltration pipe, the normal drainage of infiltration pipe has been ensured, especially in the construction of the recessed greenbelt in sponge city, can ensure the smooth discharge of rainwater, avoid the rainwater to soak the death that the plant leads to the plant for a long time, can also avoid the rainwater to soak the road bed, protect the road effectively, simultaneously, the water permeability of building block can make the water on building block upper portion better the seepage flow to in the infiltration pipe 2 and then by the infiltration pipe discharge, and is simple and convenient.
It should be noted that the building blocks, the building block device, the building block system, the building block manufacturing method and the building block construction method for the sponge city in the invention have the same principle, and related parts can be referred to each other.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
