Between pressure release steel sleeve and the middle and lower part of sole plate, inside sealing piece welding position is in pressure release steel sleeve and sole plate
Between middle part, welding form is full weld, answers timely scarfing cinder in welding process, and face of weld is answered smooth, and welding pit should fill up, and ensure
It is completely enclosed between zinc-plated aqueduct and sealing piece；
3）Fine-stone concrete is cast on drain bar 5 and pours pea gravel concreten, and the intensity of the pea gravel concreten is mixed higher than basement bottom board
Solidifying soil one grade of intensity；
4）It includes surfacing steel bar 901 and bottom layer of the reinforcing steel 902 that sole plate reinforcing bar, which binds sole plate reinforcing bar, first binds bottom layer of the reinforcing steel
902, while rectangular steel reinforcement cage is bound in 1 outside of pressure release steel sleeve, then surfacing steel bar 901 is bound, then in 1 outside of pressure release steel sleeve
It is banded with rectangular steel reinforcement cage, steel plate for sealing water 3 is between bottom layer of the reinforcing steel 902 and surfacing steel bar 901；
5）Sole plate concreting
6）It is suitable for reading with adhesive plaster temporary enclosed pressure release steel sleeve 1 before the concreting post-cast strip concreting of post-cast strip, then into
Row concreting, post-cast strip side carry out dabbing and clear up reinforcing bar, and post-cast strip concrete is used than sole plate concrete rank
The microdilatancy pea gravel concreten of a high grade, is checked oneself before the concreting of post-cast strip inside teams and groups, and then supervising engineer checks and accepts
Qualification can pour；In casting process, under vibrating head oblique cutting to steel plate for sealing water 3, the duration of vibrating should be such that concrete surface produces
Capture is starched, bubble-free, and until not sinking, the distance of shift position should be not more than 400mm, ensure not leakage, not cross to shake, and first
Progress is secondary before solidifying shakes again；
7）The pressure release steel bushing 1 for being higher by sole plate concrete is cut to by the embedded and gap closing of aqueduct to be flushed with bottom plate
Afterwards bury aqueduct 8, diversion pipe outer wall be equipped with sealing piece 2, sealing piece 2 between bottom layer of the reinforcing steel 902 and surfacing steel bar 901,
8 bottom of aqueduct extends to 6 bottom of stone layer, 8 stretching post-cast strip concrete surface 50mm suitable for reading of aqueduct or so, aqueduct 8 with let out
Gap between compressed steel sleeve 1 is filled and closely knit with microdilatancy pea gravel concreten；
8）Aqueduct blocks and floor construction is after post-cast strip concrete reaches intensity, is carried out aqueduct 8 using screw pipe cap
It blocks, then carries out floor construction.
The present invention obtains following advantageous effect by using above-mentioned technology：
1. social benefit
1）Basement bottom plate rear pouring tape leakage construction method construction is solved using service sleeve pilot method, efficiently solves basement
The key technical problem of base plate leakage water, it is disposable to solve post-cast strip percolating water problem, largely reduce later stage terrace
The difficulty of construction, while guaranteeing role is played to the construction quality of terrace；
2）The basement space that percolating water probability substantially reduces so that the underground space function of owner is not affected, and effectively reduces
Owner is to the complaint probability of Water Seepage in Basement, to generate extensive social benefit；
3）Basement bottom plate rear pouring tape leakage construction method construction basement bottom plate rear pouring tape is solved using service sleeve pilot method
Closing reaches：Good, the high-quality resultant effect of low cost, perception.
2. economic benefit
For integral construction and later period maintenance, the present invention is even compensated because reducing many grouting for water plugging and later period maintenance
Expense, more traditional post-cast strip closure construction has greater advantage from cost.This engineering method post empiricism is in original traditional cost
About 29.9 yuan/m of upper increase, needed cost summary sheet refers to the following table 1 at a pressure release diversion, and common post-cast strip maintenance cost is about
207 yuan/m, by taking 90 linear meter post-cast strips as an example, conventional construction method post-cast strip percolating water ratio is about 39%（Investigation knot in industry
Fruit）, specific cost is relatively shown in Table 2.
Needed cost summary sheet at the pressure release diversion of the invention of table 1
The cost of 2 two kinds of construction methods of table compares
To sum up compare, this engineering method can saving construction cost about 63%（Large-area backplane leak, terrace cracking expense are not counted）.
3. environmental benefit
Service sleeve pilot method solves basement bottom plate rear pouring tape and leaks construction method, and large scale saves later stage leak stopping on material
And the material of repair, and leak stopping and service material can largely generate environment different degrees of pollution, avoid tieing up because of percolating water
Repair and caused by basement space secondary pollution.Therefore this engineering method is also significant to environmental protection.
