Description
Technical Field
The invention relates to a back-attached rubber water stop structure and a construction method of a pipe gallery deformation joint, 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. For the roof, the rubber water stop covers above the concrete of the roof after the concrete is poured, a gap is easily formed between the tooth opening and the concrete, and the rubber water stop has a lap joint section at the top and water seepage hidden trouble.
