Larssen sheet pile locking guide device

Abstract

This utility model relates to the field of engineering construction technology and discloses a Larssen sheet pile interlocking guide device for guiding subsequent Larssen sheet pile interlocks to be smoothly inserted between the flanges of adjacent Larssen sheet piles that have been constructed. It includes a vertically arranged guide plate, a hanging plate, an ear plate, and threaded holes. One side of the guide plate has a guide surface that converges inward from top to bottom. The contour of this guide surface is adapted to the shape of the Larssen sheet pile interlock to be guided. The hanging plate is fixedly connected to the middle of the guide plate, fitting against the Larssen sheet, and is used to position the guide plate on the top edge of the constructed Larssen sheet pile. Through the pre-set guide surface and ear plate, the new sheet pile interlock can be quickly guided to accurate alignment, avoiding repeated adjustments by the crane. The guide structure avoids hard collisions and forced insertion between interlocks, effectively preventing wear and deformation of the interlocks, improving construction efficiency, and reducing construction costs.

Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically to a Larssen sheet pile locking guide device. Background Technology

[0002] Larssen sheet piles are an important type of retaining and waterproofing support structure, widely used in foundation pit, dam, and cofferdam projects. During construction, multiple sheet piles are interlocked one by one through interlocking joints on their edges to form a continuous wall.

[0003] In actual construction environments, the ground is often uneven, and the surface of the sheet piles may be covered with soil or corroded. This makes it very difficult for the interlocks of the subsequent sheet piles to be inserted into the flanges of the already formed sheet piles, easily leading to misalignment, jamming, or even damage to the interlocks. Traditional methods often rely on manual experience or the use of simple tools for guidance, which is inefficient and difficult to guarantee accuracy, directly affecting the construction progress and the overall water-stopping and soil-retaining performance of the wall. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a Larssen sheet pile locking guide device, which can effectively solve the problem of accurate guidance of sheet pile locking.

[0005] This utility model adopts the following technical solution: a Larssen sheet pile locking guide device, used to guide the subsequent Larssen sheet pile locking to be smoothly inserted between the flanges of adjacent Larssen sheet piles that have been constructed and formed. It includes a vertically arranged guide plate, a hanging plate, an ear plate, and a threaded hole. One side of the guide plate has a guide surface that converges inward from top to bottom. The outline of the guide surface is adapted to the shape of the Larssen sheet pile locking to be guided. The hanging plate is fixedly connected to the side of the guide plate in the middle that is in contact with the Larssen sheet, and is used to position the guide plate on the top edge of the constructed Larssen sheet pile.

[0006] The guide plate has symmetrically arranged outwardly extending ear plates on both sides of its top, which are used to guide the flanges of the Larssen steel plate lock.

[0007] The mounting plates are provided in multiple locations, which are fixedly connected to the left, middle and right positions of the guide plate, and each of them is equipped with a hook structure that matches the thickness of the Larssen steel plate.

[0008] The threaded hole is provided through the guide plate for fasteners to pass through in order to fix the guide plate to the constructed Larssen sheet pile.

[0009] The guide plate and the hanging plate are integral components with a one-piece molded structure.

[0010] Compared with the prior art, the advantages of this utility model are: through the preset guide surface and ear plate, the new steel sheet pile lock can be quickly guided to be accurately aligned, avoiding repeated adjustments by the crane. The guide structure avoids hard collisions and forced insertion between locks, effectively preventing wear and deformation of the locks, improving construction efficiency and reducing construction costs.

[0012] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0014] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a Larssen sheet pile interlocking guide device is used to guide the subsequent Larssen sheet pile interlocking smoothly into the flanges of adjacent Larssen sheet piles that have been constructed. It includes a vertically arranged guide plate 1, a hanging plate 2, an ear plate 3, and a threaded hole 4. One side of the guide plate 1 has a guide surface that converges inward from top to bottom. The outline of the guide surface is adapted to the shape of the Larssen sheet pile interlocking to be guided. The hanging plate 2 is fixedly connected to the side of the guide plate 1 that is in contact with the Larssen sheet in the middle, and is used to position the guide plate 1 on the top edge of the constructed Larssen sheet pile.

[0015] The guide plate 1 has symmetrically arranged outwardly extending ear plates 3 on both sides of its top, which are used to guide the flanges of the Larssen steel plate lock.

[0016] The hanging plate 2 is provided in multiple parts, which are fixedly connected to the left, middle and right positions of the guide plate 1, and each of them is provided with a hook structure that matches the thickness of the Larssen steel plate.

[0017] The threaded hole 4 is provided through the guide plate 1 for fasteners to pass through in order to fix the guide plate 1 to the constructed Larssen sheet pile.

[0018] The guide plate 1 and the hanging plate 2 are integral components with a one-piece molding structure.

[0019] One embodiment of this utility model: First, the construction workers directly hang the hook structure formed by the hanging plate 2 across the top edge of the first Larssen steel sheet pile 5 that has been driven into the ground. At this time, the device is initially fixed by its own weight and the constraint of the hanging plate 2. Then, the construction workers use tools to screw in the tightening bolt installed in the threaded hole 4 of the guide plate 1. The first Larssen steel plate 5 has a matching threaded hole 4. Through this operation, the device is firmly locked to the top edge of the first steel sheet pile 5.

[0020] After the device is reliably secured, the crane lifts the subsequent second Larssen sheet pile 6 and third Larssen sheet pile 7 to be inserted. The operator controls the sheet pile to descend, so that the lower end of its interlocking jaw first contacts the flared guide channel formed by the two side lugs 3 and the front of the guide plate 1. This flared entrance allows for easy correction even if there is a slight misalignment in the initial alignment. As the sheet pile 7 continues to descend, its interlocking jaw will slide naturally down the smooth guide ramp on the guide plate 1 and be precisely guided to the correct position between the interlocking flanges of the first sheet pile 5, finally achieving a smooth engagement and forming a complete interlocking state.

[0021] This involves assembling multiple Larssen steel plates to ultimately form a usable construction retaining wall.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
