Description
Technical Field
The invention relates to a construction method of a deformation joint of a pipe gallery, and belongs to the technical field of underground pipe gallery waterproofing.
Background
The construction joint and the deformation joint of the main structure of the pipe gallery are the key points of the structure in water prevention. From the construction aspect, the back-adhered rubber waterstop becomes a technical difficulty in the whole waterproof construction, and is also a key point influencing the construction quality.
As shown in fig. 1, the bottom of the pipe gallery 2 is provided with a bottom plate 1, a buried steel-edge rubber water stop 3 is arranged in plain concrete of a deformation joint of the pipe gallery, a back-attached rubber water stop 6 is arranged on the outer side of the buried steel-edge rubber water stop 3, and a steel plate water stop 5 is arranged at a horizontal construction joint 4. The main structure of the pipe gallery is generally poured in two sections, wherein the first section comprises a bottom plate and a horizontal construction joint from the bottom plate to a side wall, and the second section comprises the rest side wall and a top plate. In the first section of construction, the back-pasted rubber water stop is arranged on the outer side of a steel bar and clings to the outer steel bar, and then a template is arranged and concrete is poured. However, in the second stage of construction, the installation of the adhesive rubber waterstop is difficult, mainly because: (1) the back-pasting rubber water stop belt has a tooth opening facing inwards, and a smooth surface clings to the outer template, but before concrete pouring, a stable fixed surface or a fixed point does not exist; (2) due to the requirement of waterproofness, each annular deformation joint of the rubber water stop is complete and single, cannot be divided or segmented, and cannot be fixed in a segmented mode or fixed in a punched mode; (3) the back-bonded rubber waterstop is limited to be installed on the inner side of the template, and a clamp for installing the traditional waterstop cannot be used for installing the waterstop.
When the traditional construction is carried out at the second stage, the back-attached rubber waterstop is installed by the following steps: before pouring the side wall of the main structure, the water stop belts on the two sides are upwards stretched and fixed and are temporarily fixed at the edge of the foundation pit by binding ropes, after the side wall and the top plate are poured, before the top plate concrete is completely initially set, the back-attached rubber water stop belt upper section is bent and covered on the top plate concrete under the condition that the concrete has certain plasticity, and then the back-attached rubber water stop belt upper section is compacted.
But the back-attached rubber waterstop installation effect of the side wall and the top plate end is poor in the actual construction process. For the side wall, the rubber waterstop does not have transverse fixing and longitudinal compaction, and the phenomena that more waterstops are not tightly attached to concrete, a deflection angle is formed in the transverse direction, and half of the waterstops are buried into the concrete can occur in the actual construction effect. In the roof panel, the rubber waterstop covers the concrete of the roof panel after the concrete is poured, and a gap is easily formed between the tooth opening and the concrete.

and (3) installing the templates, respectively pouring concrete of the pipe gallery main body structures on two sides of the joint-filling plate, and removing the templates after the concrete reaches the form removal strength.
Further, finish in the setting of rectangle back of the body formula rubber stagnant water structure, before concrete placement, bury formula steel limit rubber waterstop in deformation joint department sets up along piping lane length direction, sets up the joint-filling board along the cross section direction.
And further, sealing paste is arranged between the joint filling plate and the template far away from one side of the back-attached rubber water stop structure, and the sealing paste is used for sealing deformation joints at the end parts of the joint filling plate.
Furthermore, add on the rectangle reinforcing bar internal stay ring of storehouse corresponding position department is cut apart to the piping lane and establish vertical support reinforcing bar.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following advantages and positive effects: in the construction, the formula rubber waterstop is pasted along rectangle steel bar support ring encircleed closedly on the back to the back, forms rectangle formula rubber waterstop structure is pasted on the back, has solved the fixed difficult problem of formula rubber waterstop is pasted on the back, and is closely knit between rectangle formula rubber waterstop structure and the piping lane concrete structure on the back in addition, has improved the waterproof ability of piping lane movement joint department.

Detailed Description
The construction method of the deformation joint of the pipe gallery provided by the invention is further described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent in conjunction with the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Known from the background art, because waterproof requirement needs set up back of the body formula rubber waterstop at piping lane movement joint department, then back of the body formula rubber waterstop must whole ring setting and be located the template, the fixed difficult problem of being under construction that becomes of back of the body formula rubber waterstop. The invention provides a construction method of a pipe gallery deformation joint, as shown in figure 2, a rectangular steel bar inner supporting ring 7 is arranged at the deformation joint, a back-attached rubber water stop belt 6 is surrounded and closed along the rectangular steel bar inner supporting ring 7 to form a rectangular back-attached rubber water stop structure, the fixing problem of the back-attached rubber water stop belt is solved, the rectangular back-attached rubber water stop structure and a pipe gallery concrete structure are compact, and the waterproof capacity at the deformation joint of a pipe gallery is improved.
The construction method specifically comprises the following steps:
after the construction of the pipe gallery bottom plate 1 is finished, pipe gallery reinforcing steel bars on two sides of a deformation joint of the pipe gallery 2 are bound, the back-attached rubber water stop 6 is placed on the bottom plate 1 at the deformation joint, allowance is reserved at two ends of the back-attached rubber water stop, and a tooth mouth of the back-attached rubber water stop faces upwards; arranging a rectangular reinforcing steel bar inner supporting ring 7 at a deformation joint, wherein the size of the rectangular reinforcing steel bar inner supporting ring is matched with the cross section outline of the pipe gallery 2, the bottom of the rectangular reinforcing steel bar inner supporting ring is buckled in a tooth opening of the back-sticking type rubber water stop belt, and the rectangular reinforcing steel bar inner supporting ring is fixed on the reinforcing steel bars of the pipe gallery; closing the residual parts at the two ends of the back-attached rubber waterstop along the rectangular steel bar inner supporting ring to form a rectangular back-attached rubber waterstop structure, and buckling the rectangular steel bar inner supporting ring in a tooth mouth of the rectangular back-attached rubber waterstop structure;
