Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet pile technology, and in particular to a flow-guiding Larssen sheet pile. Background Technology
[0002] With urban development, river-related projects are becoming increasingly common, including bridges, culverts, and communication, power, heating, water supply, and drainage pipelines crossing waterways. Due to the water-carrying characteristics of rivers, these projects require water diversion and drainage during construction. Currently, two common methods for water diversion and drainage are earthen cofferdams and steel formwork cofferdams. However, earthen cofferdams are prone to causing river pollution during construction and are susceptible to siltation and soil erosion; steel formwork cofferdams require the construction of temporary trestle bridges on the riverbed, which is costly.
[0003] Therefore, Larssen sheet piles are used for cofferdams in the existing construction process to ensure the normal progress of construction. However, due to the relatively thin main structure of traditional Larssen sheet piles, and the severe impact of water flow on the middle section of the Larssen sheet piles during construction, without proper flow guidance, the Larssen sheet piles are prone to damage or even breakage under the combined action of the supporting structure. Utility Model Content
[0004] Those skilled in the art have provided a flow-guiding Larssen sheet pile to address the problems mentioned in the background section.
[0005] To solve the above-mentioned technical problems, this utility model provides a flow-guiding Larssen sheet pile, including a Larssen sheet pile body, wherein inclined guide plates are symmetrically arranged on the left and right sides of the outer arc of the Larssen sheet pile body, and the inclined guide plates are welded to the Larssen sheet pile body.
[0006] The outer arc surface of the Larssen sheet pile body is provided with an outer arc guide block, and the outer arc surface of the Larssen sheet pile body is provided with an inner arc guide block. Both the outer arc guide block and the inner arc guide block are integrally made with the Larssen sheet pile body. The upper inclined surface of the outer arc guide block is provided with several first arc grooves at equal intervals, and the upper inclined surface of the inner arc guide block is provided with several second arc grooves at equal intervals.
[0007] In a preferred embodiment: the tail end of the inclined guide plate is provided as an arc-shaped surface, so that the inclined guide plate is provided in correspondence with the outer contour of the two end locking joints of the Larssen sheet pile body.
[0008] In a preferred embodiment: both the outer arc guide block and the inner arc guide block are triangular.
[0009] In a preferred embodiment: an auxiliary support plate is welded inside the inner arc surface of the Larssen sheet pile body, and a slot window is opened in the middle of the auxiliary support plate.
[0010] In a preferred embodiment: a plurality of spacer plates are welded between the auxiliary support plate and the inner arc guide block, and the second arc groove is divided by the spacer plates.
[0011] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0012] 1. In use, this utility model uses inclined guide plates that correspond to the outer contours of the locking ports at both ends of the Larssen sheet pile body to lock and connect multiple Larssen sheet pile bodies. This allows the impact water flow on the inner arc groove of the Larssen sheet pile body to be guided to the side, so that the outer arc guide block is subjected to impact. At this time, the impact water flow will flow to the upper side of the Larssen sheet pile body through the first arc groove opened in the outer arc guide block. At the same time, the impact water flow enters the slot window and, together with the second arc groove opened in the inner arc guide block, guides the water flow to the upper side of the Larssen sheet pile body, thereby alleviating the sinking problem of the Larssen sheet pile body caused by impact and reducing the breakage of the Larssen sheet pile due to excessive impact force.
[0013] 2. When this utility model is used, the second arc-shaped groove is divided by a partition plate, and the connection between the auxiliary support plate and the Larssen steel sheet pile body is stabilized, reducing deformation caused by long-term impact and increasing the fracture resistance of the Larssen steel sheet pile body.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0021] Please see Figures 1-3 In this embodiment, a flow-guiding Larssen sheet pile is provided, including a Larssen sheet pile body 1. Inclined guide plates 2 are symmetrically arranged on the left and right sides of the outer arc of the Larssen sheet pile body 1. The inclined guide plates 2 are welded to the Larssen sheet pile body 1. The tail end of the inclined guide plate 2 is set as an arc surface, so that the inclined guide plate 2 is corresponding to the outer contour of the locking mouth at both ends of the Larssen sheet pile body 1. Thus, when multiple Larssen sheet pile bodies 1 are locked together, the impact water flow on the inner arc groove of the Larssen sheet pile body 1 can be guided to the side, so that the outer arc guide block 3 is relieved of impact.
[0022] The Larssen sheet pile body 1 has an outer arc guide block 3 on its outer arc surface and an inner arc guide block 5 on its outer arc surface. Both the outer arc guide block 3 and the inner arc guide block 5 are triangular, which can effectively enhance the overall strength and stability of the Larssen sheet pile body 1. Furthermore, the outer arc guide block 3 and the inner arc guide block 5 are integrally formed with the Larssen sheet pile body 1, thereby effectively transmitting the impact of the water flow and thickening the middle part of the Larssen sheet pile body 1 to mitigate the impact. The upper part of the outer arc guide block 3 is inclined... Several first arc-shaped grooves 4 are equidistantly provided on the surface of the inner arc guide block 5, and several second arc-shaped grooves 6 are equidistantly provided on the upper inclined surface of the inner arc guide block 5. The first arc-shaped grooves 4 and the second arc-shaped grooves 6 will facilitate the impact of water flow on the middle of the outer arc guide block 3 and the inner arc guide block 5, thereby sending the impact water flow to the upper side of the Larssen steel sheet pile body 1, thereby reducing the impact on the lower side of the Larssen steel sheet pile body 1, alleviating the sinking problem of the Larssen steel sheet pile body 1 caused by the impact, and reducing the breakage of the Larssen steel sheet pile due to excessive impact force.
[0023] An auxiliary support plate 8 is welded to the inner arc surface of the Larssen sheet pile body 1. A slot window 9 is opened in the middle of the auxiliary support plate 8. The size of the slot window 9 can be adjusted and selected for welding according to the construction environment, thereby ensuring the guiding effect of water flow impact. Several spacer plates 7 are welded between the auxiliary support plate 8 and the inner arc guide block 5. The spacer plates 7 divide the second arc groove 6 and increase the connection stability between the auxiliary support plate 8 and the Larssen sheet pile body 1, reducing deformation caused by long-term impact.
[0024] The working principle of this utility model is as follows:
[0025] In use, this invention uses inclined guide plates 2 to correspond to the outer contours of the locking ports at both ends of the Larssen sheet pile body 1, thereby locking and connecting multiple Larssen sheet pile bodies 1 together. This allows the impact water flow on the inner arc groove of the Larssen sheet pile body 1 to be guided to the side, so that the outer arc guide block 3 can withstand the impact. At this time, the impact water flow will flow to the upper side of the Larssen sheet pile body 1 through the first arc groove 4 opened in the outer arc guide block 3. At the same time, the impact water flow enters the slot window 9 and, together with the second arc groove 6 opened in the inner arc guide block 5, guides the water flow to the upper side of the Larssen sheet pile body 1, thereby alleviating the problem of the Larssen sheet pile body 1 sinking due to impact and reducing the breakage of the Larssen sheet pile due to excessive impact force. At the same time, the second arc groove 6 is divided by the partition plate 7, and the connection between the auxiliary support plate 8 and the Larssen sheet pile body 1 is stabilized, reducing deformation due to long-term impact and increasing the fracture resistance of the Larssen sheet pile body 1.
[0026] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
