Abstract
The utility model discloses a replaceable water stopping structure for a concrete cofferdam settlement joint. The replaceable water stopping structure comprises a concrete cofferdam and the settlement joint in the concrete cofferdam, and further comprises a U-shaped rubber waterstop, bolts, base plates and press plates, wherein fixing portions are arranged on the two sides of the U-shaped rubber waterstop respectively, the base plates are installed on the lower surfaces of the fixing portions, the press plates are installed on the upper surfaces of the fixing portions, and the base plates and the press plates are connected into a whole through the U-shaped rubber waterstop and installed in the concrete cofferdam. The replaceable water stopping structure for the concrete cofferdam settlement joint has the advantages that due to the fact that the U-shaped waterstop structure is adopted, the replaceable water stopping structure well adapts to settlement deformation of the concrete cofferdam, and the purpose of stopping water is achieved; due to the fact that the bolts on the two sides of the U-shaped waterstop can be replaced and repaired, technical reliability and durability of the water stopping structure are improved, the application range of the water stopping structure is broadened, and the replaceable water stopping structure has the advantages of being simple in structure, safe, reliable and high in practicability.
Description
Technical field
The utility model relates to a kind of replaceable water-stopping structure for concrete cofferdam settlement joint, belongs to building preventing leaking water engineering technical field.
Background technology
At present, according to domestic water electrical engineering, work as dam, factory building foundation ditch is narrow, when Riverbed is deep again, generally take on covering layer concreting cofferdam to meet dash construction requirement, because concrete cofferdam is seated covering layer, therefore settling amount is very large, be often used for the copper seal at concrete cofferdam settlement joint place or rubber strip stroke is less and telescopicing performance is poor, when concrete cofferdam settling amount reaches after certain value, copper seal or rubber strip cannot meet the strain of sedimentation and cause drawing crack to destroy, lose water stopping function, dam, factory building foundation ditch will seep water seriously, affect engineering normal construction and incur loss through delay engineering construction progress, when taking water-pumping/draining equipment to carry out pump drainage to infiltration, increase again construction investment.Therefore, existing concrete cofferdam settlement joint water-stopping structure or not ideal enough.
Summary of the invention
The purpose of this utility model is to provide a kind of replaceable water-stopping structure for concrete cofferdam settlement joint, overcome the deficiencies in the prior art, the sedimentation and deformation that can adapt to preferably concrete cofferdam, reaches stagnant water effect, increases engineering reliability, durability and the accommodation of water-stopping structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of replaceable water-stopping structure for concrete cofferdam settlement joint, comprise concrete cofferdam and the settlement joint that is arranged in concrete cofferdam, it also comprises U-shaped rubber fastening band, bolt, backing plate and pressing plate, wherein, the both sides of U-shaped rubber fastening band are provided with fixed part, backing plate and pressing plate are arranged on respectively soffit and the upper surface of fixed part, and backing plate and pressing plate are linked into an integrated entity and are arranged in concrete cofferdam by bolt and U-shaped rubber fastening band.
In described concrete cofferdam, be provided with the installation step that U-shaped rubber fastening band is installed.
The side that meets water of described U-shaped rubber fastening band is also provided with pitch China fir plate.
The land side of described U-shaped rubber fastening band is also provided with polypropylene foam plate.
Described U-shaped rubber fastening band and bolt top are provided with epoxy mortar layer.
The beneficial effects of the utility model are: adopted U-shaped waterstop water-stopping structure, adapt to preferably the sedimentation and deformation of concrete cofferdam, reach the object of sealing, the bolt of U-shaped waterstop both sides can be changed and keep in repair simultaneously, increase engineering reliability, durability and the accommodation of water-stopping structure, and there is simple in structure, safe and reliable, practical feature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-U type rubber fastening band, 2-bolt, 3-backing plate, 4-pressing plate, 5-pitch China fir plate, 6-polypropylene foam plate, 7-epoxy mortar layer, 8-concrete cofferdam, 9-settlement joint, 10-installation step, 11-fixed part.
Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As Fig. 1, a kind of replaceable water-stopping structure for concrete cofferdam settlement joint, comprise concrete cofferdam 8 and the settlement joint 9 that is arranged in concrete cofferdam 8, it also comprises U-shaped rubber fastening band 1, bolt 2, backing plate 3 and pressing plate 4, wherein, the both sides of U-shaped rubber fastening band 1 are provided with fixed part 11, and backing plate 3 and pressing plate 4 are arranged on respectively soffit and the upper surface of fixed part 11, and backing plate 3 and pressing plate 4 are linked into an integrated entity and are arranged in concrete cofferdam 8 by bolt 2 and U-shaped rubber fastening band 1.
In described concrete cofferdam 8, be provided with the installation step 10 that U-shaped rubber fastening band 1 is installed.
The side that meets water of described U-shaped rubber fastening band 1 is also provided with pitch China fir plate 5, can prevent that so U-shaped rubber fastening band 1 is by current scour.
The land side of described U-shaped rubber fastening band 1 is also provided with polypropylene foam plate 6.
The use of pitch China fir plate 5 and polypropylene foam plate 6, all can increase the stagnant water effect of U-shaped rubber fastening band 1.
Described U-shaped rubber fastening band 1 and bolt 2 tops are provided with epoxy mortar layer 7, can ensure that like this concrete cofferdam 8 flow-passing surfaces are smooth-going, prevent bolt 2 corrosions, ensure the recoverability of U-shaped rubber fastening band 1.
When the utility model is implemented, first polypropylene foam plate 6 is embedded in advance to settlement joint 9 places of concrete cofferdam 8, by pre-buried bolt 2 and build in concrete cofferdam 8; After treating concrete setting, backing plate 3 is inserted in to bolt 2, more U-shaped rubber fastening band 1 is installed on backing plate 3, pressing plate 4 is inserted in to bolt 2 and U-shaped rubber fastening band 1 is compressed firmly; The side that meets water that finally pitch China fir plate 5 is embedded in advance to U-shaped rubber fastening band 1 is built epoxy mortar formation epoxy mortar layer 7, and epoxy mortar layer 7 is by bolt and the sealing of U-shaped waterstop.
