Description

Technical Field

[0001] The present application relates to the technical field of rubber dams, and in particular to a rubber dam fixing pressure plate. Background Art

[0002] Rubber dam, also known as rubber sluice, is a bag-type water retaining dam made of high-strength synthetic fiber fabric as a load-bearing skeleton, coated with rubber inside and outside as a protective layer, processed into rubber tape, and then anchored on the bottom plate to form a closed dam bag, which is inflated with water (air) through the filling and discharge pipeline. The dam top can overflow, and the dam height can be adjusted as needed to control the upstream water level, so as to play the role of irrigation, power generation, shipping, flood control, tide prevention and other benefits.

[0003] The existing patent (Announcement No.: CN218060187U) discloses a new type of rubber dam bag fixing structure, including several pairs of L-shaped anchor nuts, pads, pressure plates, and gaskets embedded in the concrete cushion layer. The pads are embedded on the top of the concrete cushion layer, and the rubber dam bag is laid on the pads and pressed by the pressure plates. The exposed vertical part of the anchor nut passes through the pads, rubber dam bag, pressure plates, and gaskets in turn and is tightened with a locking nut. A nut is screwed on the top of the exposed part of the anchor nut. A water stop strip is provided between the pressure plate and the concrete cushion layer. A water stop pad 1 is provided at the top and bottom of the pad, and a water stop pad 2 is provided at the bottom of the pressure plate. The cross section between a pair of anchor nuts and the locking nut is in the shape of a "J". The utility model has good fixing and anti-seepage effects on the rubber dam bag.

[0004] The above-mentioned fixed structure is provided with a waterstop strip between the pressure plate and the concrete cushion layer, a waterstop pad 1 is provided on the top and bottom of the cushion plate, a waterstop pad 2 is provided on the bottom of the pressure plate, and the cross-section between a pair of anchor nuts and locking nuts is in the shape of a "J". The above-mentioned device locks the anchor nuts through the nuts so that the nuts squeeze the waterstop strip, thereby improving the anti-seepage effect. However, during the flow of water, the vibration generated by the water flow can easily act on the nuts directly or indirectly through the dam bag. When the nuts are loose, gaps can easily appear in the rubber strips, affecting their anti-seepage effect. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a rubber dam fixing pressure plate, which has the advantages of good anti-seepage stability and solves the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a rubber dam fixing plate, comprising a dam body, a downstream groove and an upstream groove are opened on the upper surface of the dam body, the inner bottom walls of the downstream groove and the upstream groove are respectively in contact with a first pad and a second pad, the first pad, the second pad and the upper surface of the dam body are installed with a bottom gasket, a dam bag is installed on the upper surface of the bottom gasket, a gasket is provided above the first gasket and the upper surface of the second gasket, and the bottoms of the two gaskets are in contact with the upper surface of the dam bag;

[0007] Each of the washers is provided with a set of anchoring components inside;

[0009] Through the above scheme, by setting the anchoring assembly, the purpose of stable fixation of the dam bag can be achieved. At the same time, after the fixation is completed, the arc blocks of the first pad, the second pad, the bottom gasket, the dam bag and the leveling plate cooperate with the arc grooves close to them, which can effectively block the penetration of external water. By setting the mortar layer and the double nut setting, the nut can be limited to effectively prevent loosening. By setting the epoxy resin layer, the purpose of protecting the mortar layer can be achieved, further improving the overall anti-permeability.

[0010] Furthermore, the bottom end of each screw is fixedly embedded in the dam body, each pressure plate is in contact with the adjacent gasket, each screw is plugged into the adjacent gasket and pressure plate, each steel washer is sleeved with the adjacent screw, and each nut is threadedly connected with the adjacent top end of the L-shaped screw.

[0011] Through the above scheme and the provision of the anchoring assembly, the purpose of fixing the dam bag can be achieved.

[0012] Furthermore, the outer surfaces of the multiple nuts inside the downstream groove are treated with a waterproof adhesive layer.

[0013] Through the above scheme, the nut inside the downstream groove is treated with a waterproof glue layer, which can prevent the nut from loosening and increase the service life of the nut.

[0014] Furthermore, the interiors of the downstream groove and the upstream groove are both filled with a mortar layer.

[0015] According to the above scheme, the flatness of the dam surface can be ensured by filling the downstream groove and the upstream groove with mortar.

[0016] Furthermore, each of the steel washers is subjected to a galvanizing process.

[0017] Through the above scheme, the galvanized layer of the steel washer can be tightly adhered to the surface of the washer, effectively isolating the washer from oxygen and moisture in the air, thereby preventing the washer from rusting and corrosion.

[0018] Furthermore, the upper surfaces of the first pad, the second pad, the bottom pad, the dam bag and the leveling plate are all provided with a plurality of arc blocks, and the bottoms of the bottom pad, the dam bag, the leveling plate and the pressing plate are all provided with a plurality of arc grooves.

[0019] Through the above scheme, by adapting the arc groove and the arc block, the deviation of the bottom gasket, the dam bag, the leveling sheet and the pressure plate can be slowed down, and the sealing performance can be improved.

[0020] Furthermore, an epoxy resin layer is provided on the two mortar layers.

[0021] Through the above scheme, by providing the epoxy resin layer, the purpose of protecting the mortar layer can be achieved.

[0022] Furthermore, the bottom end of each screw is configured to be L-shaped.

[0023] According to the above solution, the overall anchoring strength can be improved by setting the bottom end of the screw rod to be L-shaped.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] The rubber dam fixing pressure plate can achieve the purpose of stable fixation of the dam bag through the provided anchoring assembly. At the same time, after the fixation is completed, the arc blocks of the first pad, the second pad, the bottom pad, the dam bag and the leveling plate cooperate with the arc grooves close to them, which can effectively prevent the penetration of external water. The mortar layer and the double nut settings can limit the nuts and effectively prevent them from loosening. The epoxy resin layer can protect the mortar layer and further improve the overall anti-permeability. BRIEF DESCRIPTION OF THE DRAWINGS
