[0002] Foundation pit retaining piles are divided into bored cast-in-place piles, steel column piles and steel sheet piles. Among them, the steel sheet pile is a profiled steel with a lock, which has the advantages of high strength, easy penetration into hard soil layers, can be constructed in deep water, and good waterproof performance.

[0003] As Figure 1 shown, the two sides of the steel sheet pile 1 are provided with locks 11. The locks 11 of two adjacent steel sheet piles 1 can be buckled with each other to form a cofferdam, which can block water or sediment outside the steel sheet pile 1. In order to prevent sediment or water from applying force outside the steel sheet pile 1 and causing the steel sheet pile 1 to tilt, a bracket member 2 needs to be welded inside the steel sheet pile 1, and then a steel waling 3 is installed on the bracket member 2 to strengthen the stability of the cofferdam formed by the steel sheet pile 1.

[0004] Among them, multiple bracket members 2 need to be provided and on the same horizontal plane before they can support the steel waling 3. After the construction is completed, the bracket member 2 on the steel sheet pile 1 also needs to be removed. Since the bracket member 2 and the steel sheet pile 1 are welded, it is extremely inconvenient to disassemble the bracket member 2.

[0005] In order to facilitate the installation of the bracket member 2, a hanging structure is provided on the bracket member 2, and then the hanging structure of the bracket member 2 is directly hung on the top of the steel sheet pile 2 to replace the conventional welding method to solve the problem that the bracket member 2 is not easy to remove. However, if the insertion depths of adjacent steel sheet piles are not the same, the bracket member 2 cannot be on the same plane, thus making it inconvenient to install the steel waling 3.

[0006] Therefore, how to design a retaining pile that facilitates the installation of the bracket member and the steel waling has become a technical problem to be solved urgently by those skilled in the art. Summary of the Utility Model

[0007] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a foundation pit retaining pile to solve the problem of inconvenient installation of the bracket member and the steel waling.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] This embodiment provides a foundation pit support pile, which mainly solves the installation problems of the bracket component and the steel waling.

[0028] As Figure 2 and Figure 4As shown in the figure, there are several steel sheet piles 1 that form a cofferdam and are wavy. Among them, locking grooves 11 are provided on both sides of the steel sheet pile 1. The locking grooves 11 are arranged along the length direction of the steel sheet pile 1. The locking grooves 11 of adjacent two steel sheet piles 1 are buckled with each other. The several steel sheet piles 1 are connected end to end, and thus a cofferdam can be formed to facilitate normal construction.

[0029] After the steel sheet piles 1 form a cofferdam, as the sediment inside the cofferdam is excavated, the water and sediment outside the cofferdam will exert a thrust on the outside of the steel sheet piles 1, resulting in the risk of the steel sheet piles 1 tilting. Therefore, it is necessary to add steel wales 3 inside the steel sheet piles 1 to strengthen the strength of the cofferdam and prevent the cofferdam from collapsing.

[0030] Under normal circumstances, as Figure 1 shown in the figure, after the sediment is excavated, it is necessary to weld bracket members 2 at the same height on the inside of the steel sheet piles 1, and then install the steel wales 3 on the bracket members 2.

[0031] When the construction is completed, the cofferdam needs to be demolished. At this time, the bracket members 2 are welded to the steel sheet piles 1, resulting in difficulty in disassembling the bracket members 2 from the steel sheet piles 1, which will affect the reuse of the steel sheet piles 1.

[0032] Specifically, as the bracket members 2 are shown in Figure 3 and Figure 5 the figure, they include vertical plates 21, horizontal plates 22 and support legs 23. Among them, the vertical plates 21 are arranged vertically, the horizontal plates 22 are arranged horizontally and welded to the vertical plates 21. At this time, the vertical plates 21 and the horizontal plates 22 are perpendicular to each other; when several bracket members 2 are welded to the steel sheet piles 1, it is necessary to keep the horizontal plates 22 of the bracket members 2 at the same horizontal plane to support the steel wales 3.

[0033] In order to strengthen the load of the horizontal plates 22, in this embodiment, as Figure 5 shown in the figure, the support legs 23 are arranged obliquely. One end of the support legs 23 is fixedly connected to the horizontal plates 22, and the other end of the support legs 23 is fixedly connected to the vertical plates 21.

[0034] Since the bracket members 2 and the steel sheet piles 1 are fixed by welding, it will be difficult to remove the bracket members 2 from the steel sheet piles 1. Therefore, in this embodiment, as Figure 2 、 Figure 3 and Figure 4As shown in the figure, a notch 12 is provided on the steel sheet pile 1, and a hanging part 13 is fixedly provided on the inner wall of the notch 12. Among them, the hanging part 13 is in the shape of a horizontal triangular prism. The hanging part 13 includes a first inclined surface 131 inclined downward and a second inclined surface 132 inclined upward. The included angle formed between the first inclined surface 131 and the second inclined surface 132 is an acute angle. The hanging part 13 also includes a hanging hole 133 longitudinally arranged and penetrating through the first inclined surface 131 and the second inclined surface 132. A hanging block 26 adapted to the hanging hole 133 is provided on the bracket member 2. When the bracket member 2 is installed, the hanging block 26 can be directly inserted into the hanging hole 133. At this time, the outer wall of the hanging block 26 abuts against the inner wall of the hanging hole 133, thereby restricting the shaking of the bracket member 2 and realizing the rapid installation of the bracket member 2.

[0035] It should be noted here that during the process of inserting the steel sheet pile 1 into the ground, a downward force needs to be applied to the top of the steel sheet pile 1, so that the bottom of the steel sheet pile 1 shears the soil to realize the installation of the steel sheet pile 1. Since the hanging part 13 is provided at the notch 12 of the steel sheet pile 1, the setting of the hanging part 13 will block the insertion of the steel sheet pile 1 at this time. However, in this embodiment, since the second inclined surface 132 is inclined upward from bottom to top, as Figure 3 shown, when the steel sheet pile 1 is inserted downward, the soil will be inserted downward at the sharp included angle formed between the second inclined surface 132 and the side wall of the notch 12, reducing the resistance received during the installation of the steel sheet pile 1.

[0036] When the steel sheet pile 1 is removed from the soil, in order to pull out the steel sheet pile 1 upward, at this time, a sharp angle with the tip upward is formed between the first inclined surface 131 and the side wall of the notch 12, and the first inclined surface 131 is used to break the soil layer, reducing the resistance during the extraction process of the steel sheet pile 1.

[0037] In order to facilitate the installation of the hanging block 26, in this embodiment, as Figure 6 shown, it includes a lifting horizontal plate 252. The lifting horizontal plate 252 is horizontally arranged. The hanging block 26 is fixedly installed on the bottom wall of the lifting horizontal plate 252 and extends vertically downward. The lifting horizontal plate 252 is installed on the vertical plate 21.

[0038] Since the hanging hole 133 is vertically arranged and penetrates through the first inclined surface 131 and the second inclined surface 132, when the bracket member 2 is installed, in order to improve the stability of the bracket member 2, in this embodiment, a vertically downwardly arranged lifting side plate 254 is fixedly provided on the bottom wall of the lifting horizontal plate 252. A limiting edge 2541 with the same inclination angle as the first inclined surface 131 is provided on the lifting side plate 254. When the bracket member 2 is installed on the hanging part 13, at this time, the limiting edge 2541 of the lifting side plate 254 fits with the first inclined surface 131, thereby keeping the hanging block 26 in a vertical state.

[0039] When the steel collar 3 is placed on the cross plate 22 of the bracket member 2, a vertically downward force is applied to the cross plate 22, which will cause a torsional moment on the bracket member 2. At this time, the side wall of the engaging block 26 will abut against the side wall of the engaging hole 133, thereby restricting the flipping of the bracket member 2.

[0040] In order to further enhance the stability of the bracket member 2, in this embodiment, a pushing plate 24 extending inwardly into the notch 12 is fixedly provided on the bottom side wall of the longitudinal plate 21. After the bracket member 2 is installed, the side wall of the pushing plate 24 abuts against the side wall of the notch 12. When the bracket member 2 has a tendency to flip, under the limitation of the side wall of the notch 12, the pushing plate 24 cannot tilt, thereby improving the stability of the bracket member 2.

[0041] Since the engaging portion 13 is fixedly installed on the steel sheet pile 1, when the insertion depths of two adjacent steel sheet piles 1 are inconsistent, it is likely to cause the cross plates 22 of the bracket member 2 to be not in the same horizontal position, which is not convenient for the installation of the steel collar 3. Therefore, in this embodiment, it further includes a lifting assembly 25 for adjusting the position of the engaging block 26. The position of the engaging block 26 on the longitudinal plate 21 is adjusted by the lifting assembly 25, and then the cross plates 22 of the bracket member 2 are adjusted to be in the same horizontal position.

[0042] Specifically, as Figure 3 、 Figure 5 and Figure 6 shown, the lifting assembly 25 includes a screw rod 251 rotatably installed on the pushing plate 24. The screw rod 251 is longitudinally arranged and extends vertically upward. A lifting groove 211 recessed inwardly is provided on the side wall of the longitudinal plate 21. The screw rod 251 is located in the lifting groove 211. The lifting cross plate 252 is partially inserted into the lifting groove 211. The side wall of the lifting cross plate 252 abuts against the side wall of the lifting groove 211. The screw rod 251 is threadedly connected to the lifting cross plate 252.

[0043] Through the above arrangement, since the side wall of the lifting cross plate 252 abuts against the side wall of the lifting groove 211, when the screw rod 251 rotates, the lifting cross plate 252 will rise or fall. Since the engaging block 26 is fixedly installed on the lifting cross plate 252, the position of the engaging block 26 can be adjusted at this time. After the engaging block 26 is inserted into the engaging hole 133, the cross plates 22 of the bracket member 2 are adjusted to be on the same horizontal plane.

[0044] In order to facilitate the rotation of the screw rod 251, in this embodiment, as Figure 5 shown, a knob 2511 is fixedly installed at the end of the screw rod 251, and anti-slip threads can also be provided on the side wall of the knob 2511.

[0045] In order to enable the stable lifting of the lifting cross plate 252, in this embodiment, as Figure 5As shown, a longitudinally arranged guide groove 212 is provided on the side wall of the lifting groove 211, and a guide bar 255 inserted into the guide groove 212 is provided on the side wall of the lifting side plate 254. Among them, the outer wall of the guide bar 255 is slidably connected to the side wall of the guide groove 212.

[0046] Specifically, in this embodiment, as Figure 6 shown, a lifting block 253 is fixedly provided on the bottom wall of the lifting cross plate 252, and the lifting block 253 is threadedly connected to the screw rod 251.

[0047] It should be noted here that the steel sheet pile 1 is generally arranged in a C shape. The locking groove 11 is located on both sides of the steel sheet pile 1, and the groove opening 12 is recessed on the steel sheet pile 1. When the crane assists in the installation of the steel sheet pile 1, due to the hard ground soil, the position of the locking groove 11 will deform. At this time, the hanging part 13 is arranged inside the groove opening 12, and the two ends of the hanging part 13 are used to support the side part of the steel sheet pile 1, which can strengthen the strength of the steel sheet pile 1 and reduce the risk of deformation of the locking groove 11.

[0048] Among them, multiple groups of hanging parts 13 can be arranged along the length direction of the steel sheet pile 1, and the installation of multiple layers of steel waling 3 can be realized.

[0049] Through the above settings, the locking grooves 11 of the steel sheet piles 1 can be buckled and inserted into the ground with each other, and then the hanging block 26 on the bracket member 2 is inserted into the hanging hole 133 of the hanging part 13. At this time, the limiting edge 2541 of the lifting side plate 254 abuts against the first inclined surface 131, thereby completing the preliminary installation of the bracket member 2. Then, by rotating the screw rod 251, the relative position of the hanging block 26 and the longitudinal plate 21 can be adjusted, and then the cross plate 22 on the bracket member 2 can be maintained on the same horizontal plane, thus facilitating the installation of the steel waling 3.

[0050] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
