Technical Field

[0001] The utility model relates to the technical field of waterproof blankets, in particular to a seamless overlapping joint structure of a waterproof blanket. Background Art

[0002] Bentonite composite waterproof blanket (GCL) is a new type of geosynthetic material. It is made from a mixture of graded natural sodium bentonite particles and appropriate admixtures. Through a needle-punching process and equipment, the bentonite particles are fixed between a geotextile and a woven fabric to create a blanket-like waterproof roll. Bentonite waterproof blankets combine all the characteristics of geotextiles with excellent waterproofing (and water seepage) properties. They are easy to repair and offer a relatively high performance-price ratio, making them suitable for a wide range of applications.

[0003] At present, the existing waterproof blankets are prone to gaps when overlapped, causing water to seep out, thereby accelerating the loss of water and reducing the waterproof performance of the waterproof blanket, which is not conducive to the market promotion of the waterproof blanket. For this reason, we propose a seamless overlap structure for the waterproof blanket. Utility Model Content

[0004] The purpose of the utility model is to provide a seamless overlapping joint structure of a waterproof blanket, which has the advantage of good overlapping waterproof effect and solves the problem that the existing waterproof blanket is prone to gaps when overlapping, causing water to seep out, thereby accelerating the loss of water, and reducing the waterproof performance of the waterproof blanket, which is not conducive to the market promotion of the waterproof blanket.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seamless overlapping joint structure of a waterproof blanket, comprising an overlapping base, a glue-distributing plate is provided at the middle end of the top of the overlapping base, a glue-distributing groove is provided on the top of the glue-distributing plate, a plurality of glue-through holes are provided at the upper and lower ends of the glue-distributing plate, a plurality of equally distributed connecting rods are fixedly connected to the left and right ends of the top of the overlapping base, a positioning ring groove is provided at the upper end of the connecting rod, and a plurality of equally distributed connecting rods are provided at the left and right ends of the top of the overlapping base. A bentonite waterproof blanket body is provided with a plurality of equidistantly distributed overlapping rings at one end of the bentonite waterproof blanket body close to the glue-distributing plate, and a overlapping cover plate symmetrical to the overlapping base is provided on the top of the bentonite waterproof blanket body. Positioning grooves adapted to the connecting rod are provided at the left and right ends of the bottom of the overlapping cover plate, and a receiving ring groove is provided at the middle end of the inner wall of the positioning groove. An open elastic clamp is provided on the inner side of the receiving ring groove, and a glue injection tube whose lower end is adapted to the glue-distributing groove is fixedly connected to the middle end of the top of the overlapping cover plate.

[0006] Preferably, the glue penetration holes are located on the left and right sides of the glue distributing plate, and the glue penetration holes are connected to the glue distributing groove.

[0007] Preferably, the overlapping ring is made of stainless steel, and the overlapping ring and the connecting rod are adapted to each other, and the two bentonite waterproof blankets are overlapped at the left and right ends of the top of the overlapping base through the cooperation of the overlapping ring and the connecting rod.

[0008] Preferably, the overlapping base and the overlapping cover are two symmetrically arranged U-shaped covers with both left and right ends inclined outward, and the overlapping base and the overlapping cover are both made of stainless steel.

[0009] Preferably, the lower end of the inner side of the open elastic snap ring is a conical surface, and the inner diameter of the open elastic snap ring is smaller than the outer diameter of the connecting rod. At the same time, the outer diameter of the open elastic snap ring is larger than the inner diameter of the receiving ring groove.

[0011] Preferably, a plurality of equally spaced positioning rods are fixedly connected to the middle end of the bottom of the overlapping base, and the lower ends of the positioning rods are tapered.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model facilitates the installation of two adjacent bentonite waterproof blankets on the outer surface of the corresponding connecting rod through the overlapping ring, and with the assistance of the glue-distributing plate, the two adjacent bentonite waterproof blankets are connected and docked at the left and right ends of the top of the overlapping base. The operation is simple and convenient. Then, the overlapping cover is placed on the top of the bentonite waterproof blanket to be docked, and the lower end of the glue injection tube enters the glue-distributing groove, the top of the glue-distributing plate contacts the bottom of the overlapping cover, and the upper end of the connecting rod can enter the corresponding positioning groove, and is affected by the conical surface of the lower end of the inner side of the open elastic clamp, and the inner diameter of the open elastic clamp is smaller than the outer diameter of the connecting rod. The outer diameter of the open elastic snap ring is larger than the inner diameter of the receiving ring groove, so that after the open elastic snap ring is stuck in the receiving ring groove, its outer part is still partially located in the receiving ring groove, thereby positioning the connecting rod and realizing a quick connection between the lap base and the lap cover plate. The overlapping base and the overlapping cover are two symmetrically arranged U-shaped covers with both left and right ends inclined outward, which can squeeze the bentonite waterproof blanket bodies that are connected and then seal the front and rear sides of the overlapping base and the overlapping cover after connection. After the sealing glue is injected into the glue distribution groove through the glue injection pipe, the glue can be evenly distributed into the internal space after the overlapping base and the overlapping cover are connected through the glue penetration hole, thereby ensuring the waterproof performance of the two adjacent bentonite waterproof blanket bodies after connection and connection.
