Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel sheet pile retaining device that can be reused and constructed quickly. Background Technique

[0002] For the excavation construction of the grooving support of urban infrastructure, such as the trenches of water supply and drainage pipe networks, culverts, and comprehensive pipe galleries, or the water area pile caps and piers, and construction retaining, in order to stabilize the foundation pit or play a role in blocking water, reduce the impact and damage to surrounding existing buildings, avoid disturbing the underground pipelines, and reduce the occurrence of foundation pit safety accident risks. Based on the construction difficulty, technical maturity, cost saving, and economy, the steel sheet pile support form is often adopted. To ensure the stability of the soil outside the pit or block the scouring of water flow, the "steel sheet pile purlin + horizontal cross brace" method is often used for support and reinforcement in the design. During construction, usually, steel sheet piles are driven on both sides first, steel corbels are cut out, then the steel corbels are welded to the steel sheet piles, the steel corbels support the steel purlins, and then the horizontal cross braces are propped against the steel purlins to resist the horizontal displacement of the steel sheet piles. The gap between the steel sheet piles and the purlins is filled with concrete by hanging formwork to ensure the balanced force of the purlins.

[0003] However, during the installation and removal of components such as corbels and horizontal cross braces involved in the above construction method, a large amount of manual welding and oxygen cutting work are required, especially for dangerous operations such as high-altitude edge operations and hot work, facing risks to personal and financial safety such as fires and high-altitude falls; a large amount of welding and oxygen cutting causes problems of smoke and dust pollution and light pollution. The hanging formwork usually uses cut wooden formwork, and generally, both the filling of concrete and the hanging formwork are removed in a destructive manner, which can only be used once, cannot be sustainable, cannot be continuously recycled, resulting in great waste of resources; and the waste pollutes the environment and does not meet the requirements of green environmental protection. In addition, due to a large amount of manual work, the efficiency is low, it is difficult to meet the timely support requirements of the steel sheet piles. During the period before the steel purlins and horizontal cross braces are completed, the steel sheet piles will have a large irreversible horizontal deformation tendency towards the inside, making it difficult to meet the requirements of rapid construction.

Specific embodiments

[0027] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 - 5As shown in the figure, a steel sheet pile 1 retaining device for reusable and rapid construction provided by an embodiment of the present utility model includes two rows of steel sheet piles 1, a plurality of supporting structures 2, and a plurality of supporting structures 3. The two rows of steel sheet piles 1 are arranged relatively and spaced on both sides of the trench; a plurality of supporting structures 2 are arranged on the steel sheet piles 1 at intervals, and each supporting structure 2 includes a first concave hanging plate 21 and a first supporting plate 22 connected to each other. A first groove 211 penetrating left and right is provided on the first concave hanging plate 21, the notch of the first groove 211 faces downward, a second groove 221 penetrating left and right is provided on the first supporting plate 22, the first groove 211 is used for clamping on the steel sheet pile 1, and the second groove 221 is used for supporting the steel waling 5; a plurality of supporting structures 3 are symmetrically arranged in pairs on both sides of the trench, and each supporting structure 3 includes a second concave hanging plate 31 and a second supporting plate 32. A third groove 311 penetrating left and right is provided on the second concave hanging plate 31, the notch of the third groove 311 faces downward, a fourth groove 321 penetrating front and back is provided on the second supporting plate 32, the notch of the fourth groove 321 faces upward, the side wall of the third groove 311 is fixed to the end of the fourth groove 321, the third groove 311 is used for clamping on the steel waling 5, and the two symmetric fourth grooves 321 are used for supporting the steel pipe 6.

[0029] Through a plurality of supporting structures 2 are respectively hung on the steel sheet piles 1 at intervals through the first grooves 211, and a plurality of second grooves 221 jointly form a channel penetrating left and right to support the steel waling 5; a plurality of supporting structures 3 are symmetrically arranged in pairs on both sides of the trench, and the third grooves 311 are used for clamping on the steel waling 5 or the side wall of the second groove 221, so as to support the steel pipe 6 on the two symmetric fourth grooves 321; in this structure, the steel waling 5 and the supporting structure 2, the supporting structure 2 and the steel sheet pile 1 are all detachably connected, and the steel pipe 6 and the supporting structure 3, the supporting structure 3 and the steel waling 5 or the supporting structure 2 are all detachably connected, and can be reused.

[0030] Compared with the prior art using processes such as welding, this device cancels the process of welding angle steel brackets for supporting the steel waling 5 on the steel sheet piles 1 before and during the trench construction, and cancels the process of flame cutting the angle steel brackets after the construction. The supporting structure 2 and the supporting structure 3 in this device can be combined and used repeatedly with the steel sheet piles 1, improving the utilization rate, and having the advantages of simple process, convenient installation and disassembly, capable of rapid construction, avoiding temporary electricity use, hot work welding operation and high-altitude operation at the construction site in the trench, low cost, and few potential safety hazards. It significantly improves the construction efficiency of the trench steel sheet pile 1 support and is applicable to the steel sheet pile 1 support for trench excavation.

[0031] Specifically, the notch of the second groove 221 is arranged upward. By arranging the notch of the second groove 221 upward, it is convenient to install the steel waling 5, so that when the plurality of supporting structures 2 support the steel waling 5, the steel waling 5 can be directly placed in the plurality of second grooves 221 from the upper notch at the same time.

[0032] Furthermore, the two side walls of the second groove 221 are respectively a supporting web plate 222 and a supporting limiting plate 223. The supporting web plate 222 is arranged close to the first groove 211, and the height of the supporting web plate 222 is higher than that of the supporting limiting plate 223.

[0033] By arranging the height of the supporting web plate 222 to be higher than that of the supporting limiting plate 223, it helps that when installing the steel waling 5, workers can easily lift the steel waling 5 from the trench and cross over the supporting limiting plate 223 to enter the second groove 221. The supporting limiting plate 223 helps to limit and fix the steel waling 5.

[0034] Specifically, referring to Figure 1 and Figure 2 As shown, each row of the steel sheet piles 1 includes a plurality of U-shaped steel sheets 11 connected in sequence and staggered to form adjacent convex parts 12 and concave parts 13 on the steel sheet piles 1. The convex parts 12 are close to the trench, the notch of the concave part 13 faces the trench, and the first groove 211 is clamped on the concave part 13; the supporting structure 2 further includes a filling plate 23, and the filling plate 23 is vertically arranged between the first concave hanging plate 21 and the first supporting plate 22.

[0035] Since the notch of the concave part 13 faces the trench, and the second groove 221 is also arranged on the side close to the trench. Compared with the convex part 12 being close to the trench, clamping the first groove 211 on the concave part 13 helps to increase the stability of the steel waling 5. By setting the length of the filling plate 23 to fill the distance between the concave part 13 and the convex part 12, the side wall of the second groove 221 is flush with the convex part 12 of the steel sheet pile 1, which increases the contact area between the supporting structure 2 and the steel sheet pile 1 to a certain extent, thereby improving the stability of fixing the steel waling 5.

[0036] Furthermore, the supporting structure 2 further includes a reinforcing rib plate 24. The bottom wall of the reinforcing rib plate 24 is fixed on the filling plate 23, and the two side walls of the reinforcing rib plate 24 are respectively fixed to the side walls of the first concave hanging plate 21 and the first supporting plate 22.

[0037] By arranging the reinforcing rib plate 24 on the filling plate 23, it helps to improve the supporting force of the supporting plate and prevent it from bending and deforming.

[0038] Referring to Figure 6 and Figure 7As shown, in another embodiment, it further includes a support structure 4. The support structure 4 includes a hanging portion 41 and a supporting portion 42 which are connected to each other. The hanging portion 41 is used for hanging on the convex portion 12, and the supporting portion 42 is used for supporting the steel collar 5.

[0039] By fixing a support structure 4 on the convex portion 12, the hanging portion 41 is detachably connected to the steel sheet pile 1, and the supporting portion 42 further supports and fixes the steel collar 5, so as to increase the stability of the steel collar 5 and further assist in reducing the stress on the supporting structure 2.

[0040] Specifically, the hanging portion 41 includes a first vertical plate 411, a horizontal plate 412 and an inclined plate 413. The upper end of the first vertical plate 411 is connected to the upper ends of the horizontal plate 412 and the inclined plate 413. The width of the horizontal plate 412 is adapted to the thickness of the concave portion 13. The supporting portion 42 includes a second vertical plate 421 and a supporting plate 422. The upper end of the second vertical plate 421 is connected to the lower end of the inclined plate 413. The lower end of the second vertical plate 421 is connected to one end of the supporting plate 422. The supporting portion 42 is flush with the bottom wall of the second groove 221.

[0041] The angle formed by the first vertical plate 411, the horizontal plate 412 and the inclined plate 413 is used for hanging on the upper side of the convex portion 12 of the steel sheet pile 1. Then, the second vertical plate 421 is connected and fixed to the hanging portion 41. The supporting plate 422 is flush with the bottom wall of the second groove 221. The supporting plate 422 and the second groove 221 jointly support and fix the steel collar 5.

[0042] Specifically, the supporting portion 42 can be in an "L" shape, or two vertical plates can be integrally formed to form a "U" shape. The support structure 4 is integrally formed.

[0043] Specifically, the steel collar 5 is one of an H-shaped steel, a rectangular steel, an I-shaped steel, and a channel steel.
