A rapid assembly cofferdam

Abstract

This utility model discloses a rapid assembly manhole, which includes a manhole panel, connecting components, and reinforcing components. Four manhole panels are provided and connected end-to-end to form a frame structure. Four sets of connecting components are provided, each set consisting of an mounting component and a connector. Each mounting component is placed at the corner of two adjacent manhole panels, while the connector is integrally mounted on the mounting component and inserted into the inner side of the two adjacent manhole panels. In this utility model, a slot-joint connection method is used to connect the various components of the manhole. Compared with conventional connection methods, there is no need for repeated adjustments and alignment as in traditional methods. Operators only need to precisely align the slots of the components to quickly complete the connection, greatly shortening the assembly time. In terms of structural strength, the connection structure formed after slot-joint is tight and stable, effectively resisting the powerful impact of floods.

Description

Technical Field

[0001] This utility model belongs to the field of cofferdam technology, specifically relating to a rapid assembly cofferdam. Background Technology

[0002] Cofferdams are an important emergency rescue facility. They are constructed by enclosing the dangerous area at the site of piping or leakage, and using the rise and fall of the water level inside the cofferdam to create back pressure, which balances the water pressure outside the cofferdam, thereby preventing the groundwater from continuing to gush out or the soil from being lost. This achieves the purpose of controlling the danger and stabilizing the dam, and is a key means of dealing with emergencies such as dam seepage and damage during floods.

[0003] In current flood control and disaster relief practices, cofferdams are crucial facilities for dealing with emergencies such as piping, and their assembly is of paramount importance. However, the current cofferdam assembly process has significant shortcomings. It primarily relies on metal rods inserted through pre-installed circular sleeves along the sides of the cofferdam panel for installation, a method with significant drawbacks. Firstly, its stability is poor; when faced with raging floodwaters, it is difficult to ensure the overall stability of the cofferdam structure, making it prone to loosening and displacement, thus affecting the effectiveness of flood control and disaster relief. Secondly, the sleeve's aperture is too small; during the insertion of the metal rod, operators find it difficult to accurately align the hole, requiring repeated adjustments. This not only consumes a significant amount of time and effort but also severely hinders the achievement of rapid assembly goals. Utility Model Content

[0029] In this embodiment, preferably, the mounting component includes a connecting square column 200;

[0030] The top of the connecting square column 200 is provided with a through-hole 203, and a side groove 201 is provided on the side of the connecting square column 200 facing the outside of the enclosure 100. The side groove 201 is connected to the insertion hole 203.

[0031] The reinforcing assembly is in penetrating connection with the insertion hole 203, and the arrangement of the side groove 201 allows the reinforcing assembly to be directly pushed in from the position of the side groove 201, eliminating the need to insert the reinforcing assembly with a relatively long length from the top of the insertion hole 203, which facilitates assembly.

[0032] In this embodiment, preferably, the plug-in member is a connecting protrusion 202, there are two connecting protrusions 202, and they are distributed on the side surface where the connecting square column 200 is attached to two adjacent surrounding plates 100;

[0037] The inserting rod 302 is integrally formed on the bottom end surface of the vertical rod 300; during assembly, the connecting square column 200 is first inserted into the clamping grooves 102 through the connecting protrusions 202, so as to perform limiting connection on two adjacent surrounding plates 100. At this time, the surrounding plates 100 and the connecting square column 200 should be in a vertical state, then the vertical rod 300 and the knocking block 301 are placed into the gap formed by the side groove 201, so as to realize rapid assembly of the vertical rod 300. After all surrounding plates 100 are assembled, the knocking block 301 is knocked, and the vertical rod 300 is driven by the knocking block 301 to embed the inserting rod 302 into the ground surface, so as to realize final fixed installation.
