Abstract
The invention discloses a kind of longitudinal waterstop mounting method of tunnel side wall basis, step one: longitudinally made in order by the steel limit waterstop after spreading, then pass from the end mould preformed groove on abutment wall basis to be built; Step 2: from the both sides of steel limit waterstop, the end of steel limit waterstop is clamped with two hard metal rods, then tighten respectively with the two ends up and down of iron wire by metal bar; Step 3: squeeze into holdfast on the rear wall on abutment wall basis to be built, the upper end of holdfast is towards rear-inclined, and holdfast and steel limit waterstop are positioned on same fore-and-aft plane; Step 4: be connected by wire rope with the upper end of holdfast by turnbuckle tail end, turnbuckle front end is connected by wire rope with the middle part of two metal bars, then pulls the spanner on turnbuckle, makes the waterstop tension of steel limit exceptionally straight by driving wire rope.Fundamentally improve longitudinal waterstop in tunnel side wall basis and longitudinal linearity and the poor problem of vertical orthostatic are installed, and simple to operate, there is promotional value widely.
Description
Technical field
The present invention relates to method for tunnel construction technical field, be specifically related to the mounting method of longitudinal waterstop in tunnel side wall basis.
Background technology
Longitudinal waterstop on tunnel side wall basis easily need keep straight line to install, but easily occurs not straight, tipping phenomenon etc. in practice of construction process, has a strong impact on engineering guarded drainage quality.Now current, generally adopts and steel clip is installed on steel pipe lives waterstop, or adopt two angle steel to clamp waterstop, or employing spacer bars skeleton clamps waterstop, or employing is set up bar dowel and clamped the methods such as waterstop and fixed.This several method all needs by waterstop at elongated scope internal fixtion, and the part that waterstop is embedded in concrete is very easily disturbed when concreting, its longitudinal linearity and vertical orthostatic poor.
Summary of the invention
The present invention aims to provide one conveniently longitudinal waterstop mounting method, fundamentally improves longitudinal waterstop in tunnel side wall basis and installs longitudinal linearity and the poor problem of vertical orthostatic.
For this reason, the technical solution adopted in the present invention is: a kind of longitudinal waterstop mounting method of tunnel side wall basis, comprises the following steps:
Step one: longitudinally made in order by the steel limit waterstop after spreading, then passes from the end mould preformed groove on abutment wall basis to be built;
Step 2: from the both sides of steel limit waterstop, the end of steel limit waterstop is clamped with two hard metal rods, then tighten respectively with the two ends up and down of iron wire by metal bar;
Step 3: squeeze into holdfast on the rear wall on abutment wall basis to be built, the upper end of holdfast is towards rear-inclined, and holdfast and steel limit waterstop are positioned on same fore-and-aft plane;
Step 4: be connected by wire rope with the upper end of holdfast by turnbuckle tail end, turnbuckle front end is connected by wire rope with the middle part of two metal bars, then pulls the spanner on turnbuckle, makes the waterstop tension of steel limit exceptionally straight by driving wire rope.
Preferred as such scheme, described metal bar and holdfast all can adopt the reinforcement fabrication of job site, draw materials conveniently.
The invention has the beneficial effects as follows: when installing for longitudinal waterstop, common turnbuckle, wire rope, reinforcing bar is only utilized to complete, and fundamentally improve longitudinal waterstop in tunnel side wall basis longitudinal linearity and the poor problem of vertical orthostatic are installed, and simple to operate, there is promotional value widely.
Accompanying drawing explanation
Fig. 1 is the Construction State figure of invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, a kind of longitudinal waterstop mounting method of tunnel side wall basis, comprises the following steps:
Step one: longitudinally made in order by the steel limit waterstop 1 after spreading, then passes from the end mould preformed groove 2a on abutment wall basis 2 to be built, and this step is identical with the first step that existing current longitudinal waterstop is installed.
Step 2: with the both sides of two hard metal rods 3 from steel limit waterstop 1, the end of steel limit waterstop 1 is clamped, then tighten respectively with the two ends up and down of iron wire 4 by metal bar 3, thus ensure steel limit waterstop 1 stress balance in the exceptionally straight process of tension.
Step 3: squeeze into holdfast 5 on the rear wall on abutment wall basis 2 to be built, the upper end of holdfast 5 towards rear-inclined at an angle, and holdfast 5 and steel limit waterstop 1 are positioned on same fore-and-aft plane, be to ensure the longitudinal linearity after waterstop 1 installation of steel limit and vertical orthostatic equally; Directly utilize abutment wall basis 2 to be built to install fixing holdfast 5 simultaneously.
Step 4: be connected by wire rope with the upper end of holdfast 5 by turnbuckle 6 tail end, turnbuckle 6 front end is connected by wire rope with the middle part of two metal bars 3, then pulls the spanner on turnbuckle 6, exceptionally straight by driving wire rope to make steel limit waterstop 1 strain.Turnbuckle 6, from strap wrenches, is common turnbuckle, can commercially buys.
Wherein, metal bar 3 and holdfast 5 all can adopt the reinforcement fabrication of job site.
