Description

Technical Field

[0001] This utility model relates to the technical field of road construction, specifically to a modular steel plate support pile that also provides road protection. Background Technology

[0002] In renovation and expansion projects, construction often utilizes existing roads, resulting in damage to the original road surface. Therefore, construction companies typically use measures such as laying steel plates to protect the existing roads. Furthermore, due to the presence of existing buildings, construction sites are often limited, frequently resulting in new building foundation pits being adjacent to construction roads. While steel sheet pile slope protection is a relatively economical method due to cost considerations, its reliance on the inserted portion to resist lateral earth pressure results in poor protection. The passage of construction vehicles adjacent to the road can easily lead to slope collapse. If internal bracing is installed within the steel sheet piles, the construction area becomes smaller, hindering internal construction. Additionally, when protecting existing road surfaces, traditional methods typically involve laying steel plates. These plates are large, difficult to move manually, and require mechanical equipment for relocation. Moreover, they cannot be used near the edge of the foundation pit (vehicle traffic would cause slope collapse). Utility Model Content

[0003] In order to solve one or more technical problems existing in the prior art, this utility model provides a modular steel plate support pile that also serves as a road protection device.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a modular steel sheet support pile that also serves as a road protection device, including a supporting steel sheet pile, multiple road protection steel plates, and multiple anchoring steel plates. The supporting steel sheet pile is arranged vertically and has multiple limiting tenons fixed at its upper end. The multiple limiting tenons are arranged sequentially and at intervals along the extension direction of the supporting steel sheet pile. One end of each of the multiple road protection steel plates is provided with a first insertion hole that can be adapted to and inserted into the limiting tenon. The first insertion hole is a long strip structure perpendicular to the extension direction of the road protection steel plate. The multiple road protection steel plates are all arranged horizontally. One end of each of the multiple road protection steel plates is fitted and limited on the multiple limiting tenons through the first insertion hole. The other end of each road protection steel plate can be detachably connected to a fixing bolt or an anchoring steel plate. The anchoring steel plate is arranged vertically and its upper end is detachably connected to the other end of the road protection steel plate. The height of the anchoring steel plate is not less than 1 meter.

[0005] The beneficial effects of this utility model are as follows: This modular steel sheet support pile, which also serves as a road protection mechanism, ensures the stability of the slope. The road protection steel plates can be used to tighten the upper end of the supporting steel sheet piles, which are then fixed with anchor plates or bolts. This not only allows vehicles to travel along the edge of the foundation pit but also enhances the stability of the supporting steel sheet piles. This utility model also protects the existing road surface from damage. The modular steel sheet support piles can be laid on the road at the edge of the foundation pit, and their lightweight nature makes them easy to transport. While ensuring the stability of the foundation pit slope, it protects the existing construction road, allowing dump trucks, concrete mixer trucks, etc., to approach the foundation pit for easier construction. After construction, this modular steel sheet support pile, which also serves as a road protection mechanism, can be recycled and reused, reducing construction costs. The modular design ensures construction progress and has extremely high practical value and operability.

[0018] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1 like Figures 1-6As shown, this embodiment of a modular steel sheet pile that also serves as a road protection device includes a supporting steel sheet pile 1, multiple road protection steel plates 2, and multiple anchoring steel plates 3. The supporting steel sheet pile 1 is vertically arranged and has multiple limiting tenons 13 fixed at its upper end. The multiple limiting tenons 13 are arranged sequentially at intervals along the extension direction of the supporting steel sheet pile 1. One end of each of the multiple road protection steel plates 2 is provided with a first insertion hole 21 that can be fitted and inserted into the limiting tenon 13. The first insertion hole 21 is a long strip structure perpendicular to the extension direction of the road protection steel plate 2. The multiple road protection steel plates 2 are all horizontally arranged. One end of each of the multiple road protection steel plates 2 is fitted and limited on the multiple limiting tenons 13 through the first insertion hole 21. The other end of each road protection steel plate 2 can be detachably connected to a fixing bolt or an anchoring steel plate 3. The anchoring steel plate 3 is vertically arranged and its upper end is detachably connected to the other end of the road protection steel plate 2. The height of the anchoring steel plate 3 is not less than 1 meter.

[0020] Preferably, in this embodiment, the other end of the road protection steel plate 2 is provided with a second insertion hole that runs vertically through it, and the anchoring steel plate 3 is inserted into the second insertion hole and is detachably connected to the road protection steel plate 2.

[0021] More preferably, the second insertion hole is arranged parallel to the first insertion hole 21, and the extension direction of the second insertion hole is perpendicular to the extension direction of the road protection steel plate 2.

[0022] like Figure 5 As shown, in this embodiment, the upper end of the anchoring steel plate 3 is vertically fixed with a limiting steel plate 31, and the limiting steel plate 31 abuts against the upper surface of the road protection steel plate 2.

[0023] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the limiting tenon 13 is a limiting strip protruding from the upper end of the supporting steel sheet pile 1. The limiting strip is arranged horizontally and a limiting block 14 is provided on the upper end of one side of the limiting strip. The limiting strip is inserted into the first insertion hole 21 and can be limited by the limiting block 14.

[0024] This embodiment utilizes modular steel sheet piles that also provide road protection, ensuring slope stability. Road protection steel plates tighten the upper ends of the supporting sheet piles, which are then secured with anchor plates or bolts. This not only allows vehicles to travel along the edge of the excavation pit but also enhances the stability of the sheet pile support. This embodiment also protects the existing road surface from damage. The modular steel sheet piles can be laid on the road along the edge of the excavation pit, are lightweight, and easy to transport. While ensuring the stability of the excavation pit slope, it protects the existing construction road, allowing dump trucks and concrete mixer trucks to approach the pit, facilitating construction. After construction, the modular steel sheet piles in this embodiment, which also provide road protection, can be recycled and reused, reducing construction costs. The modular design ensures construction progress and has high practical value and operability.

[0025] Example 2 Based on Example 1, this example provides a specific scheme for supporting steel sheet piles. For example... Figure 2 and Figure 3 As shown, in a specific embodiment, the supporting sheet pile 1 has a wave-shaped structure in the horizontal direction. The crests and troughs of the wave-shaped structure are both first flat strips 11 extending in the vertical direction, and the connection between the crests and troughs of the wave-shaped structure is a second flat strip 12 extending in the vertical direction. The angle between the first flat strip 11 and the second flat strip 12 is greater than 90 degrees, and multiple first flat strips 11 are arranged in parallel to each other. The upper end of each of the multiple first flat strips 11 is provided with the limiting tenon 13.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the supporting steel sheet pile 1 is formed by multiple supporting steel plate components 15 arranged sequentially in the horizontal direction and welded or connected in contact to form the wave-shaped structure; the supporting steel plate component 15 includes a first flat strip 11 and two second flat strips 12 integrally connected, and the second flat strip 12 of one supporting steel plate component 15 and the second flat strip 12 of the adjacent supporting steel plate component 15 are located on the same plane and welded and fixed.

[0027] Preferably, the multiple anchoring steel plates 3 are arranged in parallel opposite directions to the multiple first flat strips 11, each corresponding to the other.

[0028] like Figure 2 As shown, the width of the road protection steel plate 2 is greater than the width of the first flat strip 11, and the long sides of two adjacent road protection steel plates 2 abut against each other.

[0029] Preferably, the edges of the second flat strip 12 of the supporting steel plate 15 are provided with flanges, and the flanges of the second flat strips 12 of two adjacent supporting steel plate 15 are hooked together. This hooking together of two adjacent supporting steel plate 15 facilitates disassembly and assembly, and is beneficial to the stability of assembly.

[0030] Example 3 This embodiment also provides a construction method for modular steel sheet support piles that also provide road protection, including the following steps: S1, Positioning and layout: Determine the location of the foundation pit slope according to the construction drawings; S2, using a pile driver, construct the supporting steel sheet piles 1 at the slope of the foundation pit to ensure their verticality; drive the supporting steel sheet components 15 one by one into the soil for support, and the supporting steel sheet components 15 can be fixedly connected by bolts or set independently or welded together.

[0031] S3, a road protection steel plate 2 is laid on the road 4 outside the slope of the foundation pit, so that one end of the road protection steel plate 2 is fitted and fastened to the corresponding limiting tenon 13 through the first insertion hole 21; the limiting tenon 13 is about 5cm higher than the road protection steel plate 2.

[0032] S4, test the flatness and stability of the road protection steel plate during driving. If it fails, readjust the flatness of the road protection steel plate 2 until the driving test is passed. S5. If the side of road 4 away from the slope of the foundation pit is soil, then anchoring steel plate 3 is used for anchoring. If it is concrete, then fixing bolts are used to fix the other end of road protection steel plate 2 to the concrete ground. S6. After the road protection steel plate 2 is connected, the foundation earthwork is carried out at the slope of the pit. After the earthwork is completed, the backfilling is carried out. After the backfilling is completed, the anchoring steel plate 3 or the fixing bolts are pulled out, and the road protection steel plate 2 and the supporting steel sheet pile 1 are recovered.

[0033] The construction method of this embodiment can be laid on the construction road at the edge of the foundation pit. It is lightweight and easy to transport. While ensuring the stability of the foundation pit slope, it protects the existing construction road and allows dump trucks and concrete mixer trucks to get closer to the foundation pit, which is convenient for construction.
