Abstract
The utility model discloses a water-stop rubber seal for fixing a bridge open caisson transverse pile foundation in bridge pier building. The water-stop seal is characterized in that rubber rings 3 are arranged on the peripheral inner side of a hollow ring-shaped frame 1, and a plurality of fixing blocks 2 provided with bolt holes are arranged on the peripheral outer side of the frame 1. The rubber rings 3 are closed ring bodies which are continuously arranged with an extension height larger than the height of the frame, and the contour line of the section shape of the closed ring sequentially consists of a first curved line L1, a second curved line L2, a third curved line L3 and a straight line a. When the rubber seal is impacted by river sediment, the sediment acts on the curved face of the curved line L3 to lead the curved face of the curved line L1 to be tightly pressed onto a transverse pile foundation 5, and the sealing effect is in proportion to water pressure, thereby effectively preventing downdraft of the river sediment. As the curved face of the curved line L1 is tightly attached onto the transverse pile foundation 5, when in secondary concrete cast of a bridge pier, mortar is not easy to leak so as to further ensure steadiness and firmness of building quality of bridge piers.
Description
Technical field
The utility model belongs to the rubber technical field, relates in particular to open caisson and the fixing watertight rubber seal of using of horizontal pile foundation in a kind of bridge bridge pier construction.
Background technology
It is by one section one section casting concrete of sedimentation mould tube side formula that general bridge pile foundation is built, and sealing butt joint difficulty generates dislocation easily between the tube and tube; Concrete, mortar easily leak and muddy water can pour into; Typing back difficulty in decannulation; Pile foundation can be because of ground is not firm, muddy water washes away integral shift; The concrete waste, work efficiency is low, the cost height; Concrete density is high and influence pile foundation intensity, firmness and application life.So the super-huge bridge of present some such as the Yangtze Bridge in the building course of bridge pier in order to improve and strengthen the stability of bridge, by the bridge pier open caisson different depth layer to around be pressed into horizontal pile foundation, but the construction technology of this Xiang Xin must solve the sealing problem between bridge pier open caisson and horizontal pile foundation, otherwise can cause river silt in open caisson, to pour in down a chimney, and cause the leakage of mortar when the bridge pier casting concrete.
Summary of the invention
Problem to be solved in the utility model provides a kind of watertight rubber seal of good airproof performance, can prevent that river silt from pouring in down a chimney in open caisson and make when the bridge pier casting concrete mortar be difficult for leaking.
The horizontal pile foundation of bridge open caisson of the present utility model is fixing with the watertight rubber seal to be: the inner circumferential of hollow round framework 1 is provided with rubber ring 3, and the plurality of fixed piece 2 that has bolt hole is arranged on the external circumferential of framework 1.
Its middle frame 1 is formed by connecting by some flat boards and its profile is " ten " font substantially.Rubber ring 3 be arrange continuously and extended height greater than the closed circle body of frame height, the outline line of its cross sectional shape is made of in regular turn the first curve L1, the second curve L2, the 3rd curve L3, straight line a, length, the pairing chord length of the second curve L2 of the pairing chord length of the first curve L1, the pairing chord length of the 3rd curve L3, straight line a are successively decreased successively, plane, straight line a place and framework 1 are posted by connecting, and the second curve L2 place curved surface points to the center of framework 1 and exceeds framework 1.
When horizontal pile foundation 5 in bridge open caisson 4 outwards during roof pressure, it contacts with curve L1 place curved surface, is inserted easily; When river silt impacts the watertight rubber seal, silt acts on the curved surface of curve L3 place, make curve L1 place curved surface be pressed on the horizontal pile foundation 5, and sealing effectiveness is directly proportional with hydraulic pressure, prevented pouring in down a chimney of river silt effectively, owing to curve L1 place curved surface is close on the horizontal pile foundation 5, during bridge pier second casting concrete, mortar is difficult for leaking, and has further guaranteed the stable and firm of bridge bridge pier build guality.

Fig. 1 is the front view of the utility model rubber sealing seal;
Fig. 2 is the sectional view along A-A line among Fig. 1;
Fig. 3 is the scheme of installation of the utility model and bridge pile foundation.
The specific embodiment
As can be seen from Figure 1, watertight rubber seal of the present utility model is: the inner circumferential of hollow round framework 1 is provided with rubber ring 3, and the plurality of fixed piece 2 that has bolt hole is arranged on the external circumferential of framework 1.Framework 1 is formed by connecting by some flat boards and its profile is " ten " font substantially.
As can be seen from Figure 2, rubber ring 3 be arrange continuously and extended height greater than the closed circle body of frame height, the outline line of its cross sectional shape is made of in regular turn the first curve L1, the second curve L2, the 3rd curve L3, straight line a, length, the pairing chord length of the second curve L2 of the pairing chord length of the first curve L1, the pairing chord length of the 3rd curve L3, straight line a are successively decreased successively, plane, straight line a place and framework 1 are posted by connecting, and the second curve L2 place curved surface points to the center of framework 1 and exceeds framework 1.Wherein the first curve L1, the 3rd curve L3 are the identical and mutually disjoint elliptic curve of bending direction, the first curve L1, the 3rd curve L3 by both the corresponding ellipse of difference 1/4, the first curve L1 corresponding oval minor axis length greater than the corresponding long axis of ellipse length of the 3rd curve L3, the second curve L2 be semicircular circular arc line and with the first curve L1, the 3rd curve L3 is smooth is connected; Fixed block 2 and 1 vertical connection of framework, fixed block 2, the second curve L2 place curved surface lay respectively at the short transverse both sides of framework 1; The length of straight line a equals the height of framework 1.
As can be seen from Figure 3, there are a lot of reservation support holes the side of the king pile base 4 of bridge open caisson, the top pre-buried erection bolt that matches with fixed block 2 of support holes.During use, earlier watertight rubber seal of the present utility model is fixed on the side support hole bolt of king pile base, with horizontal pile foundation 5 roof pressure from inside to outside in the main body pile foundation 4, when interior outside dimension alignment request up to standard, stops then.During roof pressure, laterally pile foundation 5 contacts with the curve L1 place curved surface of watertight rubber seal, is inserted easily; When river silt impacts the watertight rubber seal, silt acts on the curved surface of curve L3 place, make curve L1 place curved surface be pressed on the horizontal pile foundation 5, and the pressure on the curved surface can increase along with the lifting of silt pressute, makes that the sealing performance of sealing ring is better, has prevented pouring in down a chimney of silt effectively, because curve L1 is close on the horizontal pile foundation 5, during bridge pier second casting concrete, mortar is difficult for leaking, and has further guaranteed the stable and firm of bridge bridge pier build guality.
