Description

Technical Field

[0001] The present invention relates to the technical field of corrosion prevention for water treatment equipment, and particularly to a multi-point bonding PE plate protection structure for water fields.

Background Art

[0002] When a multi-point bonding PE plate is adopted as a corrosion protection lining on the inner wall of a concrete water tank in a water field, the joint treatment becomes a weak point of the water blocking system. In actual construction operations in the existing technology, usually after each PE plate is individually bonded and fixed, surface heat fusion welding is performed on the butt joint of adjacent PE plates.

[0003] However, when the above method is actually in operation, if the bonding point is close to the joint, the protruding anchor plate structure will prevent the flat running of the welding tool, easily cause non-uniformity of the welding line quality, and is prone to occur incomplete welding or leakage welding. In addition, the joint is a mechanical discontinuity part of the PE plate system, and the restraint forces generated from the bonding points of each adjacent plate may form complex stress concentrations in the joint area. Cracks in the welding line are easily induced during long-term operation. When there are tiny defects in the surface welding line, the infiltrated liquid may directly spread along the joint interface and further leak through the gap between the bonding point near the joint and the concrete substrate, forming a water leakage path where "point - line" is combined, making it very difficult to investigate the cause and repair.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention discloses a multi-point bonding PE plate protection structure for water fields, aiming to solve the technical problem that there are certain disadvantages in the joint treatment process during actual construction in the existing multi-point bonding PE plate corrosion prevention treatment technology.

Means for Solving the Problems

[0005] To achieve the above object, the present invention adopts the following technical means: A multi-point dotted PE plate protective structure for use in wet areas, comprising dotted plates, and provided with a connecting mechanism that provides connection at the joints of the dotted plates;

[0006] The connecting mechanism includes a plurality of Type II docking devices embedded inside the concrete layer, the tops of the Type II docking devices are jointly connected and fixed to a single sealing strip, insertion grooves are provided symmetrically on both sides of the sealing strip, the edges of the docking plates are inserted into the insertion grooves, and a plurality of uniformly distributed injection ports are provided through the top of the sealing strip, the injection ports are in communication with the insertion grooves.

[0007] Based on existing multi-point PE plate construction technology, a Type 2 stapling tool equipped with a sealing strip structure is added. As the worker lays the stapling plate, a Type 2 stapling tool of a predetermined length is embedded in the concrete layer at the joint of the stapling plate. The sealing strip and stapling plate are connected by combining an insertion method and an insertion groove, and then heat fusion injection molding is performed through the injection port. This forms an integrated structure between the stapling plate and the sealing strip, changing the joint from the conventional "face-to-face butt welding" to "mortise-to-groove fusion welding," and by placing the fused part inside the sealing strip, the two stapling plates are physically integrated, significantly improving the structural strength along the joint area in conventional multi-point PE plate construction.

[0008] In a preferred solution, the body of the type II docking tool is composed of two docking bodies distributed at offset positions, the two docking bodies are arranged in a V-shape and embedded in a concrete layer, the two docking bodies are connected via an additionally installed wedge surface, the tops of the two docking bodies are jointly connected to an adhesive base, and the adhesive base is adhesively fixed to the bottom of the sealing strip.

[0009] The main body of the Type II stapling tool is constructed from a combination of stapling bodies and wedge surfaces distributed at two offset positions. The optimized wedge surfaces generate inward tensile force on the stapling bodies, while the wide structure generates sufficient stapling force, improving the fixing strength of the stapling tool in the concrete layer.

[0010] In a preferred solution, a passage is provided in the middle of the inlet, the passage is through-connected to insertion grooves on both sides, and a passage is opened through the interior of the sealing strip, and the passage is through-connected to the passage.

[0011] By extending and installing the opening and cavity structure based on the injection port, and by connecting the opening, cavity, and insertion groove through each other, the sealing effect during heat-seal injection molding is significantly improved. [Effects of the Invention]

[0012] As described above, the multi-point PE plate protection structure for wet areas provided by this invention has the following improvements and effects compared to existing technologies:

[0013] Based on existing multi-point docking PE plate construction technology, a Type 2 docking tool equipped with a sealing strip structure is added. As the worker lays the docking plate, a Type 2 docking tool of a predetermined length is embedded in the concrete layer at the joint of the docking plate. The sealing strip and docking plate are connected by combining an insertion method and an insertion groove, and then heat-seal injection molding is performed through the injection port. This forms an integrated structure between the docking plate and the sealing strip, physically integrating the two docking plates and significantly improving the structural strength and resistance along the joint area in conventional multi-point docking PE plate construction, while simultaneously perfecting the docking plate construction process.

[0018] The multi-point PE plate protection structure for water areas disclosed in this invention is mainly applicable to waterproofing construction of water tanks and the inner walls of pipes.

[0019] Referring to Figures 1 to 3, the multi-point dotted PE plate protection structure for water areas comprises a dotted plate 1, and a connecting mechanism 2 is provided to connect the joints of the dotted plate 1;

[0020] The connecting mechanism 2 includes a plurality of Type II docking tools 201 embedded inside the concrete layer. The tops of the Type II docking tools 201 are jointly connected and fixed to a single sealing strip 202. Insertion grooves 203 are provided symmetrically on both sides of the sealing strip 202. The edges of the docking plate 1 are inserted into the insertion grooves 203. Multiple uniformly distributed injection ports 204 are provided through the top of the sealing strip 202, and the injection ports 204 communicate with the insertion grooves 203.

[0021] In this embodiment: The operator lays the roll-shaped dotting plate 1 flat on the surface of the concrete layer at the laying position. At the same time, along the end of the dotting plate 1 laid at the same time, the second-class dotting tool 201 at the bottom of the sealing strip 202 is buried together inside the concrete layer, and then the laying of the dotting plate 1 continues along the other side of the sealing strip 202. Then, the adjacent ends of the two dotting plates 1 are inserted into the insertion groove 203 inside the sealing strip 202, and at the same time, while gently moving the top of the sealing strip 202 parallel using a heat fusion machine, a heat fusion adhesive is injection-molded. The heat fusion adhesive flows into the insertion groove 203 through the injection port 204, whereby the three of the two dotting plates 1 and the sealing strip 202 are integrated.

[0022] Here, a plurality of rows of first-class dotting tools 101 are provided at the bottom of each dotting plate ①. When the operator lays the dotting plate 1, it is ensured that the first-class dotting tools 101 are distributed on the surface close to the concrete layer, and the first-class dotting tools 101 are buried inside the concrete layer. Also, the main body of the second-class dotting tool 201 is composed of dotting bodies 2011 distributed with a displacement in two positions, and the two dotting bodies 2011 are arranged in a V shape and buried in the concrete layer. The two dotting bodies 2011 are connected through an additionally installed wedge surface 2012 in between. The tops of the two dotting bodies 2011 are jointly connected to an adhesive pedestal 2013, and the adhesive pedestal 2013 is adhesively fixed to the bottom of the sealing strip 202. Due to the connection between the dotting bodies 2011 distributed with a displacement in two positions and the wedge surface 2012, the wedge surface 2012 generates an inward pulling force on the dotting bodies 2011, and at the same time, the wide structure generates sufficient dotting force, improving the fixing strength of the second-class dotting tool 201 in the concrete layer. The same principle applies to the first-class dotting tools 101.

At the same time, a through cavity 2021 is opened penetrating inside the sealing strip 202, and the through cavity 2021 is connected to the through hole 2041 in a penetrating manner to further improve the flow path of the heat fusion adhesive.

[0024] Working principle: During use, the operator flattens the roll-shaped dotting plate 1, directs the first type of dotting tool 101 located at the bottom of the dotting plate 1 towards the concrete layer, places the dotting plate 1 on the surface of the concrete layer at the laying position, and embeds the first type of dotting tool 101 into the concrete layer. At the same time, along the end of the laid dotting plate 1, the second type of dotting tool 201 at the bottom of the sealing strip 202 is also embedded into the concrete layer, and then the laying of the dotting plate 1 continues along the other side of the sealing strip 202. Then, the adjacent ends of the two dotting plates 1 are inserted into the insertion groove 203 inside the sealing strip 202, and at the same time, while gently moving the top of the sealing strip 202 parallel using a heat fusion machine, a heat fusion adhesive is injection molded. The heat fusion adhesive flows into the insertion groove 203 through the injection port 204, thereby integrating the three of the two dotting plates 1 and the sealing strip 202.
