Description

Technical Field

[0001] This utility model relates to the field of paste filling technology, specifically to a paste filling baffle device. Background Technology

[0002] When treating mined-out areas, paste filling is used to seal the area. Due to limitations in on-site construction conditions, it is often impossible to seal the entire area using a single piece of sealing fabric. Multiple pieces of sealing fabric are usually spliced ​​together to achieve the desired seal. During the splicing process, poor sealing at the overlap points often leads to grout leakage. Furthermore, during the filling process, the grout compresses the sealing fabric, causing it to tear and detach under vertical tension, resulting in further grout leakage. Summary of the Invention

[0003] This invention addresses the problems of poor sealing at the joints of the sealing cloth used to seal the paste during paste filling in mining areas and the ease with which the sealing cloth is damaged by the vertical tension of the paste. It provides a paste-blocking device that can improve the sealing effect of the paste and extend the service life of the sealing cloth.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A paste-filling slurry-blocking device includes a baffle plate supported by a bracket on its rear side, and further includes a sealing cloth and a buffer cloth. The sealing cloth is provided on the front side of the baffle plate. The sealing cloth is composed of multiple connecting cloths connected in sequence. In two adjacent connecting cloths, the left end of the right connecting cloth is bonded and fixed to the right end of the adjacent left connecting cloth. The upper and lower ends of the sealing cloth are bonded and fixed to the upper and lower sides of the baffle plate, respectively. Each connecting cloth has a buffer cloth on its upper and lower front sides. The buffer cloth is composed of an adhesive part and a force-bearing part. The lower end of the force-bearing part is fixedly connected to the connecting cloth. The adhesive part is located between the force-bearing part and the connecting cloth. The lower end of the adhesive part is fixedly connected to the connecting cloth. The upper end of the adhesive part is connected to the upper end of the force-bearing part. The adhesive part and the force-bearing part are integrally formed. The rear side of the adhesive part is bonded to the front side of the connecting cloth through an acrylic adhesive layer.

[0006] Furthermore, in the two adjacent connecting fabrics, the left end of the right connecting fabric covers the front side of the right end of the adjacent left connecting fabric, and the left end of the right connecting fabric and the right end of the adjacent left connecting fabric are bonded together with an epoxy resin adhesive layer.

[0007] Furthermore, the upper and lower ends of the sealing cloth respectively cover the upper and lower sides of the baffle, and the upper end of the sealing cloth is bonded to the upper side of the baffle and the lower end is bonded to the lower side of the baffle with epoxy resin adhesive.

[0008] Furthermore, the bonding strength of both the first epoxy resin adhesive layer and the second epoxy resin adhesive layer is 10000 mPa·s.

[0009] Furthermore, the lower end of the adhesive portion of the same cushioning cloth is higher than the lower end of the force-bearing portion.

[0010] Furthermore, in the same connecting fabric, the lower end of the force-bearing part of the upper buffer fabric is close to the upper end of the force-bearing part of the lower buffer fabric.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] In use, the two adjacent connecting cloths are connected by an epoxy resin adhesive layer to prevent the paste from leaking at the connection point between the two adjacent connecting cloths. The sealing cloth is connected to the baffle by an epoxy resin layer to improve the connection strength between the sealing cloth and the baffle and prevent it from falling off.

[0013] When the buffer cloth of this invention is subjected to a vertical tension of the paste, the adhesive part of the buffer cloth separates from the connecting cloth, ensuring that the force-bearing part of the buffer cloth has a margin for downward movement after being subjected to force. This buffers the vertical downward force of the paste, preventing the sealing cloth from breaking or falling off due to the tension of the paste, thus avoiding leakage and improving the service life of the sealing cloth.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-4As shown, a paste-filling slurry-blocking device includes a baffle 1, the rear side of which is supported by a bracket 2. It also includes a sealing cloth and a buffer cloth 3. The front side of the baffle 1 is provided with a sealing cloth, which is composed of multiple connecting cloths 7 connected sequentially. Each connecting cloth 7 is a rectangular sheet. In two adjacent connecting cloths 7, the left end of the right connecting cloth 7 is bonded to the right end of the adjacent left connecting cloth 7. The upper and lower ends of the sealing cloth are bonded to the upper and lower sides of the baffle 1, respectively. Each connecting cloth 7 has a buffer cloth 3 on its upper and lower front sides. The buffer cloth 3 is a rectangular sheet, and it consists of an adhesive part 3a and a force-bearing part 3b. The structure comprises a connecting cloth 7 fixedly connected to the lower end of the force-bearing part 3b, an adhesive part 3a located between the force-bearing part 3b and the connecting cloth, the connecting cloth 7 fixedly connected to the lower end of the adhesive part 3a, and the upper end of the adhesive part 3a connected to the upper end of the force-bearing part 3b. The adhesive part and the force-bearing part are integrally formed. The rear side of the adhesive part 3a is bonded to the front side of the connecting cloth via an acrylic adhesive layer 4. After the acrylic adhesive layer is cured, it exhibits good elasticity and shear properties, and does not contain organic solvents, so it will not damage most substrate surfaces. The cured acrylic adhesive layer is relatively soft and has strong adhesion, but its material mechanical properties are low, making the internal structure of the acrylic adhesive prone to breakage when shear force is applied.

[0021] In the two adjacent connecting cloths 7, the left end of the right connecting cloth 7 covers the front side of the right end of the adjacent left connecting cloth 7, and the left end of the right connecting cloth 7 and the right end of the adjacent left connecting cloth 7 are bonded together by epoxy resin adhesive layer 5.

[0022] The upper and lower ends of the sealing cloth cover the upper and lower sides of the baffle 1, respectively. The upper end of the sealing cloth is bonded to the upper side of the baffle 1, and the lower end is bonded to the lower side of the baffle 1 with epoxy resin adhesive layer 6.

[0023] The bonding strength of epoxy resin adhesive layer 5 and epoxy resin adhesive layer 6 is 10000 mPa·s.

[0024] The lower end of the adhesive portion 3a of the same buffer cloth 3 is higher than the lower end of the force-bearing portion 3b.

[0025] In the same connecting cloth 7, the lower end of the force-bearing part 3b of the upper buffer cloth 3 is close to the upper end of the force-bearing part 3b of the lower buffer cloth 3.

[0026] When in use, the side of the buffer cloth 3 of this utility model faces the area to be filled, and the baffle 1 of this utility model makes the upper and lower ends of the sealing cloth press against the top and bottom surfaces of the area to be filled.

[0027] When the paste is filling the area to be filled, the two adjacent connecting cloths 7 are bonded together by epoxy resin adhesive layer 1, which can improve the connection between the two adjacent connecting cloths 7, making the connection tight and preventing the paste from leaking through the connection between the two adjacent connecting cloths 7. Moreover, the upper and lower ends of the sealing cloth are bonded to the upper and lower sides of the baffle 1 by epoxy resin adhesive layer 2 6, which can improve the connection between the sealing cloth and the baffle 1 and prevent the sealing cloth from falling off the baffle 1.

[0028] Furthermore, during the filling process, the paste first contacts the buffer cloth 3 on the front side of the connecting cloth 7. When the paste applies a vertical downward pulling force to the buffer cloth 3, the force-bearing part 3b of the buffer cloth 3 moves downward under the force. The force-bearing part 3b pulls the adhesive part 3a on the rear side. After the acrylic adhesive layer 4 on the rear side of the adhesive part 3a is subjected to shear force, the internal structure of the acrylic adhesive layer 4 breaks after the shear force is applied. The adhesive part 3a peels off from the connecting cloth 7 from top to bottom, ensuring that the force-bearing part 3b of the buffer cloth 3 still has room for movement in the vertical direction. This buffers the vertical downward force of the paste and avoids leakage caused by the sealing cloth breaking or falling off due to the pulling force of the paste.

[0029] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
