Abstract
The invention discloses a method for guaranteeing waterproof construction quality of a deep foundation pit basement. The method is a basement waterproof construction technology without sufficient waterproof working surface. Under the condition of a shorter distance between a deep foundation pit edge and an outer wall structure of a building basement, the waterproof coating and waterproof roll constructions on the outer side of the outer wall are performed after the outer wall of the basement is constructed according to the traditional method, but people cannot enter into a narrow space between the outer wall and the foundation pit wall in such a manner. A construction method without sufficient working surface can be adopted for changing the construction process, so that the problem of insufficient operation surface can be successfully avoided and the waterproof quality and the construction safety can be guaranteed.
Description
Technical field
The invention belongs to technical field of buildings, and in particular to a kind of deep basal pit waterproofing for basement quality of ensure that
Method.
Background technology
With China's rapid urban, urban land katatonosis constantly expose, and are to increase building in land red-line
It is 3 layers ~ 4 layers increasingly common to the utilization rate design of basement in place, but in basement structure outer contour and land red-line
Spacing volume Jing is often less between foundation pit walls, is difficult to construct when external wall structure and waterproof construction.Traditionally under first construction ground
Room exterior wall outside waterproof under construction ground again, workman cannot enter in the case of the deficiency of space between foundation pit walls and outer wall of basement
Enter narrow space construction, most direct consequence is exactly to cause waterproof roll and water-repellent paint construction quality to ensure, if by force
Potential safety hazard may also can be caused into construction, therefore using " one kind makees face for ultra-deep foundation pit basement without enough waterproofers
Way " is moved back construct from outside to inside from outdoor backfill, waterproof, outer wall of basement, there is enough operating surfaces, so as to ensure construction quality
With construction safety.
The content of the invention
It is an object of the invention to provide a kind of method that ensure that deep basal pit waterproofing for basement quality, for super
Deep basal pit basement is without enough work surface working procedures.
What the present invention was realized in：Including outdoor concrete backfill, waterproof construction, external wall construction, specially following step
Suddenly：
The first step：Outer fill concrete and exterior wall boundary line are determined on raft plate, exterior wall edge positions are released, outwards offset 0.5 ~
1cm releases full hall bracing frame vertical rod position, the lateral pressure according to produced by fill concrete as backfill template plate face sideline
Go out the vertical rod row of implantation reinforcing bar needed for vertical rod bottom, set up the full hall frame of template and increase corresponding steel pipe, support body checks and accepts after-pouring
Concrete is simultaneously conserved, and outer backfill needs to be higher by correspondence exterior wall 28 ~ 35cm of height when pouring, it is ensured that waterproof is overlapped；
Second step：Construction waterproof after backfill form removable, water-repellent paint is brushed as requested in backfill, and water-repellent paint is checked and accepted
After the completion of construction waterproof coiled material, waterproof construction according to《Technical code for water proof in underground engineering》GB50108 is performed；
3rd step：Colligation exterior wall reinforcing bar, and check and accept；
4th step：Structure outer inner side one side formwork is installed and checked and accepted, and completes concreting.
Beneficial effects of the present invention：The present invention is for ultra-deep foundation pit basement without enough work surface working procedures, waterproof volume
Material is made on outdoor fill concrete rather than on external wall structure face with water-repellent paint；There is provided " frame is multiplex " full hall simultaneously to support
Frame, maximally reduces the construction cost of working procedure of the present invention.The present invention adopts new working procedure, but in order to ensure the new work
The realization of sequence is made that new adjustment to waterproofing process, water-repellent paint brushing and coiled material is pasted and has been made in outer backfill, and
Effect is preferable.The innovation on one side formwork is fixed improves full hall bracing frame, and structure floor bracing frame is used in twice into vertical list
In the fixation of side template, cost is successfully reduced.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further illustrated, but the present invention must not be any limitation as by any way,
Based on present invention teach that any change for being made or improvement, belong to protection scope of the present invention.
Method of the present invention includes outdoor concrete backfill, waterproof construction, specially external wall construction, following steps：
The first step：Outer fill concrete and exterior wall boundary line are determined on raft plate, exterior wall edge positions are released, outwards offset 0.5 ~
1cm releases full hall bracing frame vertical rod position, the lateral pressure according to produced by fill concrete as backfill template plate face sideline
Go out the vertical rod row of implantation reinforcing bar needed for vertical rod bottom, set up the full hall frame of template and increase corresponding steel pipe, support body checks and accepts after-pouring
Concrete is simultaneously conserved, and outer backfill needs to be higher by correspondence exterior wall 28 ~ 35cm of height when pouring, it is ensured that waterproof is overlapped；
Second step：Construction waterproof after backfill form removable, water-repellent paint is brushed as requested in backfill, and water-repellent paint is checked and accepted
After the completion of construction waterproof coiled material, waterproof construction according to《Technical code for water proof in underground engineering》GB50108 is performed；
3rd step：Colligation exterior wall reinforcing bar, and check and accept；
4th step：Structure outer inner side one side formwork is installed and checked and accepted, and completes concreting.
Outer backfill needs to be higher by correspondence exterior wall height 30cm when pouring, it is ensured that waterproof is overlapped.
Single side formwork support body realizes that a frame is multiplex in 4th step, by the full hall bracing frame of floor of constructing in advance, by support body point
Do not pour support, exterior wall concrete for fill concrete and pour support, floor concrete casting support, the diagonal brace 1 set up leads to
Cross rotary buckle to be connected on the column of support body middle part, increase support body anti-overturning energy.
The horizontal continuity bridging 2 increased on first step fullness in the epigastrium and abdomen hall supporting frame and vertical bridging 5 are used to strengthen full hall
The globality of bracing frame.
Set up in 3rd step embedded bar 3 be for increase support body skid resistance in lateral concreting, it is to avoid support body to
After translate.
The diagonal brace 7 set up is connected and withstands in template with full hall frame steel pipe, once ensures molding and the frame of concreting
The overall performance of body.
Temporary support bar 8 withstands on outboard template backfill by being connected on overall support body when outdoor backfill is poured in the first step
On, temporary support bar 8 is dismountable after the completion of the backfill construction of outside, it is ensured that can continue second in the case that full hall frame is integrally motionless
Step exterior wall returns back to top.
Coiled material is attached to outdoor fill concrete facade by waterproof roll using " viscous in preventing outward " method waterproof 13 in second step,
Exterior wall concrete 11 is poured again.
