Description
Technical field
The utility model relates to technical field of tunnel construction, particularly relates to the stationary fixture of buried water stop in the short abutment wall of a kind of tunnel invert.
Background technology
Waterproof and Drainage Construction of Tunnel, as one critical process, controls to seem particularly important in work progress.By original construction experience technical level construction, middle buried water stop is when concrete built by inverted arch, because of the impact by concrete gravity and mobility, middle buried water stop is very easily distorted, sideslip, reserved size are nonstandard, thus it is comparatively serious to cause constuction joint place to seep water, erosion is caused to construction of tunnel entity quality, during operation, also can leave hidden danger to driving.For guaranteeing engineering entity quality, be strictly on guard against that percolating water phenomenon appears in construction joint of tunnel, buried water stop in how fixing fast and effectively, stop to occur tunnel is carried out to water blockoff, harnesses the river, this just requires guarded drainage construction of will keeping under strict control in work progress.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides the stationary fixture of buried water stop in the short abutment wall of a kind of tunnel invert.
The technical scheme adopted for realizing the purpose of this utility model is:
The stationary fixture of buried water stop in the short abutment wall of a kind of tunnel invert, comprise as longitudinal bracing and two square steel type main joists that middle buried water stop is clamped, along main joist longitudinally every the hard-wired fixture of 30-50cm, the upper end face of two described main joists to be positioned in same level and wherein respectively the reinforcing bar of abutment wall short with inverted arch be fixedly connected with, described fixture comprises crossbeam and is separately positioned on two vertical longerons of horizontal gird both sides, bolt and nut is respectively arranged with bottom described vertical longeron, the inner of described bolt to hold on the lateral surface of main joist and is fixedly clamped by middle buried water stop.
Described fixture is welded to form by angle steel.
Bottom described vertical longeron, be provided with through hole, have internal thread nut in the inner side of through hole or arranged outside.
Described fixture setting space is 40cm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, not yielding, workable; Effectively can control the position of waterstop, expose size and straight degree; Material consumption is little, turnover is convenient, and construction cost is low, uses after terminating and also waste and oldly can utilize section bar, substantially do not have economic loss.Utilize effectively easy working measure, technical ability guarantees the rapid construction of engineering entity quality high-quality, cost-savingly can pay again, realizes maximizing the benefits simultaneously.
Accompanying drawing explanation
Fig. 1 is the structure transverse face figure that the utility model separate type waterstop fixture is installed;
Fig. 2 is the structure front view that the utility model separate type waterstop fixture is installed.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, in the short abutment wall of tunnel invert of the present utility model, the stationary fixture of buried water stop 4 comprises as longitudinal bracing and two the square steel type main joists 1 clamped by middle buried water stop, along main joist longitudinally every 30-50cm, the hard-wired fixture 2 of preferred 40cm, the upper end face of two described main joists to be positioned in same level and wherein respectively the reinforcing bar of abutment wall 3 short with inverted arch be fixedly connected with, the crossbeam 21 that described fixture comprises angle steel formation and the vertical longeron 22 that two angle steel being separately positioned on horizontal gird both sides are formed, bolt and nut 23 is respectively arranged with bottom described vertical longeron, the inner of described bolt to hold on the lateral surface of main joist and is fixedly clamped by middle buried water stop 4, namely bottom described vertical longeron, through hole is provided with, internal thread nut is had in the inner side of through hole or arranged outside, the location realizing fixture and main joist is coordinated by bolt and internal thread bolt.
Hollow square steel formula main joist longitudinal length of the present utility model comparatively designs the long 1m of inverted arch length, each reserved 50cm in termination, both sides, and hollow square steel bottom surface absolute altitude comparatively designs short abutment wall constuction joint height 1cm, and the utility model structure is simple, not yielding, workable; Effectively can control the position of waterstop, expose size and straight degree; Material consumption is little, turnover is convenient, and construction cost is low, uses after terminating and also waste and oldly can utilize section bar, substantially do not have economic loss.Utilize effectively easy working measure, technical ability guarantees the rapid construction of engineering entity quality high-quality, cost-savingly can pay again, realizes maximizing the benefits simultaneously.
When separate type waterstop fixture described in the utility model embodiment is installed, first surveying and locating is passed through, determine middle buried water stop installation site and absolute altitude, by streamlined bone by electric welding mode, as spot welding and existing reinforcing bar are connected and fixed, keel bottom surface is higher than inverted arch short abutment wall constuction joint 2cm, the waterstop tiling that will install launches, longitudinally sprawl along the keel fixed, another bar keel is installed, then utilize equidistant fixture by two bar keels, sealing strap clamp is extremely fixing, will on the same face when two bar keels are installed, faulting of slab ends must not be formed, otherwise can sideslip be there is in waterstop.
The Specific construction technological process of separate type waterstop fixture is as follows: the short abutment wall reinforcing bar binding → inverted arch of inverted arch floats mould and to be in place → another bar keel → sectional fixture of surveying and locating waterstop installation site → a fix main joist → waterstop of mating formation → install → build inverted arch concrete → dismounting fixture and main joist.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
