Description

Planting surface waterproof system

Technical Field

The invention relates to the field of building roof waterproofing, in particular to a planting surface waterproofing system.

Background

Nowadays, with the further pursuit of people for living quality, people often plant flowers and plants on roofs or indoors, on one hand, the plot can be smelted, and on the other hand, the air environment can be improved.

But when the plants are planted on roofs or indoors, the planting surfaces are required to have good waterproof capacity, otherwise, the quality of houses is influenced.

Current planting face generally sets up drainage pipe, arranges the rainwater collection outward to waterproofing membrane's burden on the reduction planting face, also can reduce waterproofing membrane's use thickness. At present drainage pipe's structure has generally been seted up the infiltration hole for the surface, wraps up the pipeline through the screen cloth, avoids the infiltration hole to be stifled, and the infiltration hole is generally seted up the half-turn, and when laying drainage pipe, the infiltration hole is up. In the mode, because the water seepage is small, rainwater can directly flow to the waterproof coiled material along the drainage pipeline easily, and the waterproof coiled material has heavy pressure bearing (water pressure) and is easy to leak.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a planting surface waterproof system which has good waterproof performance.

The technical purpose of the invention is realized by the following technical scheme: plant face waterproof system, top-down include planting soil layer, filter layer, water drainage layer, look for slope layer, waterproofing membrane, reinforced concrete structure layer, water drainage layer includes drainage pipe, the rubble of packing between drainage pipe that the interval was arranged, drainage pipe includes first semicircle pipe and second semicircle pipe, first semicircle pipe diameter is less than the second semicircle pipe, first semicircle pipe is located second semicircle pipe top and both openings relatively, sets up the infiltration hole on the first semicircle pipe, and the outer wall of first semicircle pipe and its arc extension face form the clearance with the outer wall of second semicircle pipe and its arc extension face, and above-mentioned clearance is sealed through the wire net, covers the cloth that permeates water on the wire net, first semicircle pipe, second semicircle pipe and wire net form a closed loop cavity, second semicircle pipe one end is sealed, and the other end is seted up a drainage mouth.

Water enters the drainage layer from the planting soil layer through the filter layer, and a small part of the water enters the closed-loop chamber through the water seepage holes; because the clearance is larger, most of water enters the closed-loop chamber along the first semicircular pipe through the clearance, the water is accumulated in the second semicircular pipe, and when the water overflows the water outlet, the water is discharged from the water outlet; the gravel can play a certain role in filtering and blocking the soil of the planting layer, the steel wire mesh plays a role in bearing, and although the two-layer filtering system with the filtering layer and the gravel layer is provided, soil particles of the planting layer are possibly brought to flow downwards by water, so that the water permeable cloth is arranged. This scheme is through discharging most water again through the clearance, reduces water and flows to waterproofing membrane's probability along drainage pipe process rubble.

Furthermore, a supporting seat is installed in the closed-loop cavity, and the upper end and the lower end of the supporting seat are respectively abutted to the inner walls of the first semicircular pipe and the second semicircular pipe.

The supporting seat is used for playing a supporting role and reducing the possibility that the first semicircular tube deforms after being pressed.

Further, a limiting plate is fixed to each of the two sides of the supporting seat, one end of the steel wire mesh is abutted to the second semicircular pipe opening, and the other end of the steel wire mesh extends to the upper end face of the limiting plate and is abutted to the limiting plate.

When the steel wire mesh is installed, the steel wire mesh can be directly placed on the second semicircular pipe and the limiting plate, then the first semicircular pipe is placed on the steel wire mesh, and the steel wire mesh is convenient and quick.

Furthermore, the steel wire mesh side forms an extension portion, the extension portion supports against the inner wall of the second semicircular pipe.

When the wire net was placed on second semicircle pipe opening and limiting plate, thereby extension butt second semicircle intraductal wall played the effect of restriction wire net horizontal migration.

Furthermore, the bottom of the supporting seat is provided with a positioning plate, and the inner wall of the second semicircular tube is provided with a positioning groove matched with the second semicircular tube.

The locating plate can play certain restriction supporting seat horizontal migration's effect with the cooperation of constant head tank, also makes things convenient for the quick location installation of supporting seat simultaneously.

Furthermore, a water absorbing piece is fixed in the supporting seat, a water inlet hole communicated with the water absorbing piece is formed in the position, close to the bottom of the second semicircular pipe, of the supporting seat, and the water absorbing piece extends to the planting soil layer.

The water in the second semicircular pipe is accumulated to a certain degree and then discharged from the water outlet, so that certain water is accumulated in the second semicircular pipe, and the water can be supplied to the planting soil layer through the water absorbing piece.

Further, the supporting seat is formed by splicing two supporting parts with the same structure, and the water absorbing piece is clamped between the supporting parts.

Thus, the whole structure is more modularized; because the second semicircle pipe is laminated with supporting seat lower extreme butt, consequently the second semicircle pipe has the limiting displacement to the horizontal displacement of supporting seat lower extreme, and first semicircle pipe is laminated with supporting seat upper end butt, and consequently first semicircle pipe has the limiting displacement to the horizontal displacement of supporting seat upper end, and first semicircle pipe and second semicircle pipe receive the horizontal displacement restriction of rubble, consequently need not adopt screws etc. to connect two supporting parts, can keep the stability of whole structure.

Furthermore, the height from the lower end of the water outlet to the bottom of the inner wall of the second semicircular pipe is 5-8 mm.

5-8mm can keep the basic water storage capacity of the second semi-circular pipe.

In conclusion, the invention has the following beneficial effects: this scheme simple structure, the installation is convenient fast, and can promote waterproof performance.
