Abstract
The invention discloses a water stop and guide structure of a bridge expansion joint. The water stop and guide structure comprises a water stop band, wherein a water stop slot is formed in the middle part of the water stop and guide structure; telescopic member mounting tank regions are formed in beam end parts of two sides of the bridge expansion joint. The water stop and guide structure is characterized in that the water stop band is arranged below a telescopic member; two side parts of the water stop band extend into the telescopic member mounting tank regions on the corresponding sides; filling layers for wrapping and fixing the side parts of the water stop band are poured into the telescopic member mounting tank regions. The water stop and guide structure of the bridge expansion joint has the advantages that the side parts of the water stop band are wrapped and fixed by the filling layers, so that rainwater can be prevented from leaking out from combined surfaces between the water stop band and the filling layers, and a complete water sealing effect can be achieved; then the water stop band cannot be stressed by outer force in the later-period using process and is difficult to damage and long in service life; at last, a water guide pipe can guide the rainwater in the water stop slot into a bridge water drainage system or a ground water drainage system, and therefore, the phenomena of leakage and icing of the rainwater, which are caused by a fact that the rainwater is gathered in the water stop band, can be avoided, and the water stop band can be also prevented from directly draining water to two sides of a bridge or the outer side of the bridge.
Description
Technical field
The present invention relates to bridge expansion joint installation, especially relate to a kind of sealing water guide structure of bridge expanssion joint.
Background technology
The Water stop structure of existing bridge expanssion joint mainly contains following form:
1, the waterstop of deformed steel class bridge expanssion joint is " V " shape structure, both sides are mounted in respectively in the mounting groove of deformed steel, in the both sides of bridge or extend the directly draining of bridge outside, or be upturned and do not have a drain function, rainwater amasss and in waterstop, easily produces seepage or icing phenomenon.And in use procedure, all kinds of rubbish (the particularly harder class such as stone) is easily fallen into structure, after vehicle spreading in " V " shape waterstop the super many not easy to clean of ultraproduct, and can cause stretching device to lose its Telescopic, " V " shape waterstop also can, because extruding produces breakage seepage, lose its water stopping function.
2, the Water stop structure of comb plate class bridge expanssion joint is generally arranged on comb plate bottom, or directly additionally arrange in comb plate bottom, erection bolt by comb plate is fixed, or be fixed on the both sides beam-ends at shrinkage joint by anchor structure independently, waterstop is after being used certain hour, and rainwater will be gone out by the anastomotic leakage between itself and beam body.Another waterstop is in the both sides of bridge or extend the directly draining of bridge outside, or is upturned and does not have a drain function, and rainwater amasss and in waterstop, easily produces seepage or icing phenomenon.
Visible, above-mentioned two kinds of different Water stop structures all do not reach desirable effectively sealing, do not possess drain function, cannot meet the thorough Mi Shui in existing urban viaduct, must not occur seepage or in line requirement outside bridge.
Summary of the invention
First technical problem to be solved by this invention is that the sealing water guide structure that can not be subject to the bridge expanssion joint of External Force Acting the thorough Mi Shui of energy in a kind of use procedure is provided for above-mentioned prior art present situation.
Second technical problem to be solved by this invention is for above-mentioned prior art present situation, to provide in a kind of use procedure, not to be subject to External Force Acting, thorough Mi Shui have the sealing water guide structure of the bridge expanssion joint of water guide function.
The present invention solves the problems of the technologies described above adopted technical scheme: the sealing water guide structure of this bridge expanssion joint, include waterstop, the middle part of described waterstop forms water stopping trough, the beam end of bridge expanssion joint both sides forms telescoping member mounting groove district, it is characterized in that: described waterstop is located at the below of telescoping member, the both sides of waterstop are stretched in the telescoping member mounting groove district of respective side, in telescoping member mounting groove district, are cast with the packed layer that waterstop sidepiece is wrapped.
In order to make the close water better effects if between waterstop and packed layer, described waterstop sidepiece is male and fomale(M&F) structure, and described packed layer wraps described male and fomale(M&F).
The male and fomale(M&F) structure of waterstop sidepiece can have various ways, preferably, at described waterstop sidepiece, is provided with sealing ball or sealing post to form described male and fomale(M&F) structure.
In order to prevent rainwater from putting aside rear freezing in water stopping trough, affect the flexible of stretching device, on described waterstop, be provided with and can the rainwater in water stopping trough caused in bridge drainage system or directly cause the aqueduct in surface drainage system.Aqueduct can adopt the various materials such as rubber, plastics to make, and its length can be set according to on-the-spot actual needs.
In order to obtain better water guide effect, described water stopping trough is U-shaped groove, and described aqueduct is many and along the length direction of waterstop, is distributed in the bottom of U-shaped groove.
In order to prevent that rain-water accumulating in water stopping trough from spilling after full, described waterstop extends to the bottom of bridge guardrails of both sides along bridge width direction, and forms the warping part above bridge floor at the two ends of waterstop length direction.
Telescoping member can adopt different structures, as a kind of preferred version, described telescoping member comprises the irregular section bar that is positioned at bridge expanssion joint both sides and is fixed on separately described homonymy packed layer top, the upper surface of special-shaped section and the upper surface flush of packed layer, waterstop member is installed between irregular section bar, and described waterstop is positioned at the below of described waterstop member.This scheme, by waterstop member is installed, not only can realize double-deck stagnant water effect, and can also prevent that all kinds of rubbish from falling into the water stopping trough of waterstop.
Another kind of preferred version as telescoping member, described telescoping member comprises the metal baffle that is positioned at bridge expanssion joint both sides and is fixed on separately described homonymy packed layer top, clamping between metal baffle have an aquiclude, and described waterstop is positioned at the below of described aquiclude.Aquiclude can adopt with the elastomeric material of water stop function and make.
As another preferred version of telescoping member, described telescoping member comprises the comb plate structure being laid on described packed layer, and described waterstop is located at the below of described comb plate structure.In this preferred version, stretching device can be the expansion gap device with changeover portion concrete, can be also the expansion gap device without changeover portion concrete.
Compared with prior art, the invention has the advantages that: first, because waterstop sidepiece stretches in telescoping member mounting groove district and the packed layer of being poured into a mould wraps thereby can prevent that rainwater from going out from the bonding surface seepage between waterstop and packed layer, thereby reach the effect of thorough Mi Shui; Secondly, waterstop can independently be arranged on the bottom of telescoping member, and in later stage use procedure, can not be subject to External Force Acting, not fragile, long service life; Finally, the aqueduct being arranged on waterstop can cause in bridge drainage system by the rainwater in water stopping trough or directly cause in surface drainage system, thereby can not only avoid rainwater to amass in waterstop, producing seepage and icing phenomenon, can also avoid waterstop to the both sides of bridge or the direct draining in the outside of bridge.
