Through-hole is offered on the side side wall of pipe；
（4）Step（3）Middle waterproof steel plate top is laid with negative side waterproofing layer, and negative side waterproofing layer is overlapped with bed course waterproof, waterproof
Casing winds water expandable waterstop with waterproof steel plate weld, and the negative side waterproofing layer of water expandable waterstop turns over, waterproof
Layer makes and finishes, and pours fish tail and waterproof layer and building foundation raft plate；
（5）After the installation positioning of underground pipe group, hair is injected with by through-hole in the gap between water string and underground pipe
Polyurethane is steeped, through-hole is blocked equipped with bolt；The gap top of water string and underground pipe be provided, in sequence from bottom to top, with baffle ring,
First of rubber ring, lead oil flax silk layer, second rubber ring and compacting short tube flange, compacting short tube flange and water string
Between by connect bolt fix, then pour ground cushion on building foundation raft plate；
（6）Ground waterproof layer is made in the upper surface of ground cushion, ground waterproof layer is combined with the top of water string, short pipe method
Flame-retardant expanded polyurethane seal is used at blue connection bolt, then does cement protective layer above ground level, facilitates later maintenance.
2. wearing the waterproofing process of building foundation raft plate according to above-mentioned underground pipe group, the underground pipe in the underground pipe group
Underground pipe sleeve bottom in the underground pipe group uses steel plate, and upstream face, back side do integral face waterproof, using PE plastics
Underground pipe.
The waterproofing process of building foundation raft plate is worn according to above-mentioned underground pipe group, compresses short tube and flange plate is all made of state
The gap of mark, baffle ring and underground pipe is controlled in 3 ~ 5mm, and the bottom of baffle ring sets 4 45 ° of poling flow deflectors.
Compared with prior art, the advantageous effect that the present invention obtains：
1. the bottom end full weld of water string is had waterproof steel plate by structure of the invention, the anti-of building foundation raft board bottom portion can be avoided
Occur waterproof layer at jacket pipe to lack and then influence the hidden danger such as basement integral waterproofing；It is offered on the side side wall of water string
Through-hole, is injected with polyurathamc in the gap between water string and underground pipe by through-hole, and through-hole is sealed equipped with bolt
Stifled, which solves the problems, such as that lower half can not fill waterproof filler, waterproof under building foundation raft plate in water string
In gap between casing and underground pipe after injecting glue, bolt seal；The gap top of water string and underground pipe from bottom to top
It is equipped with baffle ring, first of rubber ring, lead oil flax silk layer, second rubber ring and compacting short tube flange, flexible water rubber successively
Add spunyarn between cushion rubber, slight void between filled rubber pad further seals；Using fire-retardant at the connection bolt of short tube flange
Polyurathamc sealing corrosion antirust, is conducive to the maintenance of water-tight device.
2. the gap of structure of the invention guide ring and underground pipe is controlled in 3 ~ 5mm, the bottom of baffle ring sets 4 45 ° of polings and leads
Flow, the structure is convenient for importing underground pipe.
3. using the above structure, the present invention obtains preferably in later maintenance, energy consumption, safety in production etc.
Economic benefit.
