Abstract
The invention discloses a kind of high artesian post-cast strip to be depressured leak-blocking construction method, drainage and step-down is carried out to post-cast strip (A) leakage using stainless steel tube (1), suction hose (2), ring flange (11), water pump etc., the stainless steel tube (1) is directly embedded in below late poured band (A) place again, closes the concrete of existing leak stopping point and hypotensive point.Compared with prior art, present invention process is simple, and speed of application is fast；Built-in fitting is fixed reliably, especially for the higher area of some level of ground water hydraulic pressure, is fully able to meet design and construction code requirement using the construction of this method.
Description
Technical field
The invention belongs to building field, is related in water under high pressure area basement bottom board seepage reduction technology field, especially relates to
A kind of and high artesian post-cast strip decompression leak-blocking construction method.
Background technology
In building construction concrete structure construction, basement post-pouring zone construction processing emphasis, handle not in work progress
When different degrees of Seepage, especially higher in level of ground water and larger hydraulic pressure area will occur, after there is seepage
Due to water pressure problem, very big puzzlement is caused to blocking construction, the quality of leak stopping is not easy to ensure and causes repeatedly to do over again.Once side
Method is improper, and not only can't resolve leakage problems can also increase the construction time limit indefinite duration.Particularly level of ground water higher area from
Right hydraulic pressure is higher, deals with improperly, makes because basement floor has been molded, post-cast strip has poured completion, during post empiricism
Into part and large-scale water leakage, do not reach requirement and design, delay the duration.Trace it to its cause when being post-cast strip concrete construction
Decompression processing is not carried out, and the cement mortar in the concrete of construction is washed away loss by head, is caused inside concrete structure into honeycomb
Shape, formed compared with mass-flow seepage.
The content of the invention
Goal of the invention：Decompression tube caused by order to solve traditional construction technique, which can not fill, forms new seepage at reality and decompression tube
The defects of point, spy develop a kind of high artesian post-cast strip decompression leak-blocking construction method, and technique is simple, and speed of application is fast, built-in fitting
It is fixed reliable, meet design and construction code requirement.
Technical scheme：A kind of high artesian post-cast strip is depressured leak-blocking construction method, utilizes stainless steel tube, suction hose, method
Blue disk, water pump etc. carry out drainage and step-down to post-cast strip leakage, then stainless steel tube is directly embedded in lower section at late poured band,
The concrete of the existing leak stopping point of closing and hypotensive point.
Comprise the following steps that：
1st, at the post-cast strip for seepage occur, 100~200mm width is added to chisel operation well by every side, the straight angle in both sides
Chisel to structure reinforcing bars position, and carry ring flange high-pressure water head position occur and bury a 50~200mm of diameter and one end
Stainless steel tube, the pipe surrounding concrete tight closure of the stainless steel tube, if necessary, using waterproof apron to described stainless
Steel pipe is closed；
The diameter of the stainless steel tube need to be adjusted and determine according to drainage and step-down amount；
2nd, described stainless steel tube one end is connected with suction hose by flange, the suction hose and the water pump phase of outside
Even, do not shut down by water pump pressure draw water, draining, until the post-cast strip surface without bright water, then carry out breakthrough repairing,
Plugging operation；
3rd, after the completion for the treatment of plugging operation, then continue not shut down pressure and draw water, until artesian water can not be flat to operation well surrounding 2
It is non-corrosive in square rice, after other positions to be verified repairing is intact, remove the suction hose that is connected with stainless steel tube flange and
Outside water pump；
4th, at the ring flange of described stainless steel tube one end, sealed with the stainless steel plate and waterproof apron in strap bolt hole
It is stifled；
5th, after the completion of blocking, in the concrete of preparation pouring practice well, appropriate micro-expanding agent will be added and label is tied than former
Structure concrete improves a label, and operation well is poured and closed.
Beneficial effects of the present invention：Compared with prior art, present invention process is simple, and speed of application is fast；Built-in fitting is fixed
Reliably, especially for the higher area of some level of ground water hydraulic pressure, using the construction of this method be fully able to meet design with
Job specfication requirement.
Brief description of the drawings
Fig. 1 is drainage and step-down process diagrammatic cross-section in post-cast strip of the present invention；
Fig. 2 is that post-cast strip drainage and step-down of the present invention completes diagrammatic cross-section.
Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Embodiment：
A kind of high artesian post-cast strip is depressured leak-blocking construction method, using stainless steel tube 1, suction hose 2, ring flange 11,
