Abstract
The utility model relates to a wet joint anti-seepage device of a bridge pier body. The wet joint anti-seepage device of the cross-sea bridge pier body is characterized in that a water-stop rubber strip (2) is arranged at the connecting position between the top end of a bearing platform (1) and a prefabricated main pier (3). The water-stop rubber strip can be automatically expanded when meeting water, blocks off a water seepage gap, intercepts a water seepage channel, prevents seepage, and has good anti-seepage effect.
Description
Technical field
The utility model relates to a kind of pier shaft wet joint percolator of bridge.
Background technology
Have benefited from the high-quality reliability and high efficiency ratio of prefabricated mounting structure, directly be provided with in the bridge spanning the sea of pier shaft wet joint structure at imperial scale at prefabricated pier shaft and cast-in-place cushion cap and obtained extensive use, but crackle generally occurred building and building in the similar bridge spanning the sea work progress, the bridge structure durability that is in ocean severe environment has been constituted certain threat.Bridge spanning the sea pier shaft wet joint is all built by reinforcing bar and cement and is constituted.It is common and breakneck occurring the crack after cement is built, and when slight gap occurring, needs in time to repair to prevent its crack, infiltration back, slit its safety that widens one's influence.External crack can carry out skin patching by cement etc., but by infiltrating the water of wet joint inside and chlorion wherein just can't eliminate in the crack.
Summary of the invention
Goal of the invention of the present utility model is in order to solve the above-mentioned technical problem that existing bridge spanning the sea pier shaft wet joint exists, and provides a kind of crack infiltration that can prevent cushion cap end face and prefabricated pier shaft junction to cause the bridge spanning the sea pier shaft wet joint percolator of crack expansion.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of bridge spanning the sea pier shaft wet joint percolator, cushion cap top and prefabricated main pier junction are provided with the watertight rubber bar.
As preferably, described watertight rubber bar is many, and its bottom of imbedding cushion cap is provided with a plurality of downward opening U-lags, and place is provided with a plurality of circular holes in the middle of it.
Owing to adopted a kind of bridge spanning the sea pier shaft wet joint percolator of above-mentioned technical scheme, be provided with the watertight rubber bar on cushion cap top and prefabricated main pier junction, when the crack appears in the pier shaft wet joint, water infiltrates when having buried the slit of watertight rubber bar underground, the watertight rubber bar is met water and is just expanded voluntarily, stop up the infiltration slit, block penetrating passage, stop seepage, impervious effective, and have the watertight rubber bar bulk expansion of above-mentioned shape and structure and compress anti-good springiness, speed of expansion is slow, the expansion potentiality are big, and the hydraulic pressure resistance ability is strong, are particularly suitable for using on the pier shaft wet joint of bridge spanning the sea.
Description of drawings
Fig. 1: example structure schematic diagram of the present utility model.
Fig. 2: the schematic diagram of sealing rubber strip among the embodiment of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1-2 the specific embodiment of the present utility model is made a detailed explanation.
A kind of bridge spanning the sea pier shaft wet joint percolator as shown in Figure 1 and Figure 2, cushion cap 1 top and prefabricated main pier 3 junctions are provided with watertight rubber bar 2.Watertight rubber bar 2 is 2, and its bottom of imbedding cushion cap 1 is provided with a plurality of downward opening U-lags 5, and place is provided with a plurality of circular holes 4 in the middle of it.
The crack appears in the pier shaft wet joint, water infiltrates when having buried the slit of watertight rubber bar 2 underground, and watertight rubber bar 2 is met water and just expanded voluntarily, stops up the infiltration slit, block penetrating passage, stop seepage, impervious effective, and have watertight rubber bar 2 bulk expansion of above-mentioned shape and structure and compress anti-good springiness, speed of expansion is slow, the expansion potentiality are big, and the hydraulic pressure resistance ability is strong, are particularly suitable for using on the pier shaft wet joint of bridge spanning the sea.
The foregoing description only is a this patent embodiment preferably, and the structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
