Abstract

A method for putting a water permeable pipe in a plastic sleeve to drain water and prevent water relates to underground engineering roof plates and roofs, which are engineering parts needing rainwater drainage and water prevention. In the prior art, a drain board is connected with a drain pipe to form a closed shape, air in the drain pipe can be discharged by arranging an air outlet pipe on the drain pipe for smooth drainage, a further improvement is continuously made for eliminating the air outlet pipe, and the integral structure method can also replace the function of root puncture resistance. The invention mainly changes the closed drain pipe into an open plastic sleeve pipe, so that an air outlet pipe is not needed to be installed, and a permeable pipe is arranged in the plastic sleeve pipe, so that the main water flow is filtered and then is quickly discharged in the permeable pipe. The waterproof layer of the invention is provided with an integral concrete surface layer, an anti-cracking reinforcing mesh is matched, and a root-puncture-resistant sheet is locally paved on the plastic sleeve, so that the waterproof layer can replace the root puncture resistance, and is a system integrating prevention, drainage and root puncture resistance.

Description

Method for placing water permeable pipe in plastic sleeve for draining water and preventing water

Technical Field

The invention relates to a roof slab and a roof of underground engineering, which are engineering parts needing rainwater drainage and water prevention.

Background

The inventor has applied for the invention of the application number of the method for connecting the drain board and the drain pipe in a sealing way to form a waterproof and drainage system: 2018106255799, the technique is to connect the drain board with the drain pipe to form a closed shape, so that the drain pipe is provided with an air outlet pipe for discharging air in the pipe. In the actual construction of engineering, because the night construction of backfill earthwork truck can cause the damage to the air outlet pipe, in order to cancel the air outlet pipe, further improvement is continuously made, and the integral construction method can also replace the function of root puncture resistance.

Disclosure of Invention

The invention mainly changes the closed drain pipe into an open plastic sleeve pipe, and does not need to install an air outlet pipe, in order to prevent the open plastic sleeve pipe from being blocked by sundries to influence the drainage, a permeable pipe made of plastic messy wires or a permeable pipe wound by steel wires and then sleeved with filter cloth is arranged in the plastic sleeve pipe, so that the main water flow is quickly discharged in the permeable pipe after being filtered. The landscape arrangement on the top of the top plate can be planted and greened, and the specification requires that the waterproof coiled material can resist root puncture, because the waterproof layer of the invention is provided with the integral concrete surface layer which is matched with the anti-cracking reinforcing mesh, and then the root puncture resistant sheet is locally paved on the plastic sleeve, the root puncture resistant function can be replaced.

The specific method comprises the following steps: the method comprises the steps of firstly pasting waterproof materials on a structural top plate, then arranging plastic sleeves in parallel, in a grid or in a fishbone mode at certain intervals, then placing permeable pipes with filtering action diameters matched in the plastic sleeves, pouring concrete at intervals of the plastic sleeves, enabling the concrete to be flat with the sides of the plastic sleeves, enabling the middle of the concrete to be slightly high, then laying a plastic drainage plate on a concrete plane, enabling a supporting point to be upward, finally fully laying geotextile on the whole drainage top plate surface, enabling rainstorm to be converged into the plastic sleeves from the drainage plate through the filtering of the geotextile, and rapidly discharging the structural top plate from the permeable pipes through the filtering of the permeable pipes. The drainage plates extend into the plastic sleeve, and are lapped with each other along the slope, and the lapping parts can be connected by hot melting or glued.

Pouring concrete at the interval between the plastic sleeves, arranging an anti-cracking reinforcing mesh in the middle of the concrete, cutting the concrete surface layer into separate bin seams, embedding factice into the separate bin seams to form an integral reinforced concrete protective layer with root puncture resistance, paving a plastic sheet with the root puncture resistance on the upper part of the water permeable pipe, and enabling the top plate of the integral structure to have the root puncture resistance.

The invention replaces the closed drain pipe with the open drain sleeve, cancels the air outlet pipe, is convenient for the follow-up construction such as earth backfill and the like, protects the quality of the waterproof layer and replaces the root puncture resistance, and is a system integrating the prevention, the drainage and the root puncture resistance.
