Description

Technical Field

[0001] This utility model relates to the field of foundation pit protection technology, and in particular to a steel sheet pile with built-in foundation pit protection column insertion holes. Background Technology

[0002] Foundation pit protection is widely used on construction sites. However, traditional foundation pit protection is more dependent on the surrounding environment. For example, standardized protective netting requires hardened ground around the site for easy installation, and steel pipe protection requires guardrail posts to be driven into the perimeter of the foundation pit for easy implementation. In addition, the posts need to be fixed to the ground by concrete pouring or other additional measures, otherwise the stability of the foundation pit protection will be affected.

[0003] A search revealed Chinese patent CN214091355U, which discloses a novel protective enclosure for foundation pits, comprising columns, nuts, L-shaped brackets, chains, hardened ground, expansion bolts, and baffles. The hardened ground is located on the ground surrounding the foundation pit. The lower end of each column has a rectangular plate, which is fixedly installed on the hardened ground by multiple expansion bolts and nuts. The L-shaped brackets are fixedly connected to the columns, and studs are provided on the horizontal portion of the L-shaped brackets. The chains are fixedly connected to the side walls of the baffles, with the holes of the chains fitting onto the studs of the L-shaped brackets and secured by nuts. The L-shaped brackets are welded to the columns, and at least two L-shaped brackets are welded to each column.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Although the aforementioned patent can achieve the protection of the foundation pit, the installation of its columns requires fixing them to the ground with bolts, and the ground must be hardened. It is similar to traditional foundation pit protection methods, which are too dependent on the surrounding environment, resulting in poor practicality and thus certain limitations. Utility Model Content

[0006] To address the aforementioned technical issues, this utility model proposes a steel sheet pile with built-in insertion holes for foundation pit protection columns. This allows for rapid prefabricated construction of foundation pit protection without relying on the surrounding environment, enabling the columns to be fixed through the insertion holes on the steel sheet pile. This saves time, makes the construction process convenient and quick, and further improves the level of on-site safety management.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a steel sheet pile with a self-contained foundation pit protection column insertion hole, comprising multiple steel sheet piles 1, with steel sheet pile 2 being clamped between each two adjacent steel sheet piles 1, a pair of collars fixedly installed on the outer side of each steel sheet pile 1, a column being slidably installed inside each pair of collars, and a fastening bolt threadedly connected to each collar, with the end of the fastening bolt abutting against the column.

[0008] Preferably, each of the columns is fixedly installed with multiple fasteners, and multiple crossbars are fixedly connected to one side of the multiple columns through the fasteners.

[0009] Preferably, a casing is fixedly installed on the inner side of each sheet pile, and a bidirectional threaded rod is rotatably installed inside the casing. The bidirectional threaded rod rotatably penetrates the sheet pile, and hexagonal blocks are fixedly installed at both ends of the bidirectional threaded rod.

[0010] Preferably, both ends of the bidirectional threaded rod are connected to clamping rods by threads, and each clamping rod has a clamping block fixedly installed at its end.

[0011] Preferably, a baffle is welded to one side of each sheet pile, and the upper surface of the baffle is in contact with the bottom of the column.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model, by setting a collar and fastening bolts on the sheet pile, can stably fix the column, thus eliminating the need for fixing installation based on the surrounding environment. Utilizing the prefabricated construction concept, the collar does not affect the sheet pile driving process, and after the sheet pile is driven, the column can be fixed with fastening bolts and collars. Horizontal bars are fixed on the column, and protective netting is installed on the column and horizontal bars, quickly forming the foundation pit enclosure and realizing rapid prefabricated construction for foundation pit protection.

[0014] Secondly, this utility model can clamp and fix the column by setting a bidirectional screw and a clamping rod, thereby further improving the fixing effect of the column. In addition, a baffle is welded on one side of the steel sheet pile, which can limit the bottom of the column and prevent the column from loosening and sliding during the enclosure period, thus affecting the protection effect.

[0015] This solves the problem that while existing technologies can protect foundation pits, the installation of the columns requires bolts to be fixed to the ground, and the ground must be hardened. This is similar to traditional foundation pit protection methods, which are overly dependent on the surrounding environment, resulting in poor practicality. Attached Figure Description

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved steel sheet pile with integrated foundation pit protection column insertion holes. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, a steel sheet pile with self-contained pit protection column insertion holes includes multiple steel sheet piles 1. Each pair of adjacent steel sheet piles 1 is connected to a steel sheet pile 2. A pair of collars 4 are fixedly installed on the outer side of each steel sheet pile 1. A column 6 is slidably installed inside each pair of collars 4. Each collar 4 is threaded with a fastening bolt 5. The end of the fastening bolt 5 abuts against the column 6. Through the collars 4 and fastening bolts 5, the column 6 can be fixed without the aid of the external environment, thereby realizing rapid prefabricated construction of pit protection and improving construction efficiency.

[0025] Furthermore, each column 6 is fixedly installed with multiple fasteners 8, and multiple horizontal bars 7 are fixedly connected to one side of the multiple columns 6 through the fasteners 8. The fasteners 8 make it easy to connect the horizontal bars 7 to the columns 6 in a simple and stable manner, which facilitates the subsequent installation of the protective net.

[0026] As a further embodiment of this utility model, a protective sleeve 13 is fixedly installed on the inner side of each sheet pile 1. A bidirectional threaded rod 9 is rotatably installed inside the protective sleeve 13. The bidirectional threaded rod 9 rotatably passes through the sheet pile 1. Hexagonal blocks 10 are fixedly installed at both ends of the bidirectional threaded rod 9. The protective sleeve 13 can provide support for the installation of the bidirectional threaded rod 9, and the hexagonal blocks 10 can not only facilitate the rotation of the bidirectional threaded rod 9 by the workers, but also play a limiting role.

[0027] Furthermore, both ends of the bidirectional threaded rod 9 are connected to clamping rods 11 by threads, and each clamping rod 11 is fixedly installed with a clamping block 12 at its end. The clamping rods 11 and clamping blocks 12 can clamp and fix the column 6 to a certain extent, thereby improving the stability of the protective device.

[0028] Furthermore, a baffle 3 is welded to one side of each sheet pile 1. The upper surface of the baffle 3 is in contact with the bottom of the column 6. The baffle 3 can limit and fix the column 6, effectively preventing the column 6 from sliding down and affecting the protective effect of the protective device.

[0029] The specific working method is as follows: After the sheet piles 1 and 2 are fixed around the foundation pit, the column 6 is installed in the collar 4 on the sheet pile 1 until the bottom of the column 6 abuts against the baffle 3. Then, the fastening bolts 5 are tightened in sequence. Then, the hexagonal stop block 10 rotates the bidirectional threaded rod 9, which in turn moves a pair of clamping rods 11 and clamping blocks 12, thereby achieving the clamping and fixing effect of the column 6, further improving the fixing effect of the column 6, and thus improving the stability of the protective device. After the column 6 is fixed, the crossbar 7 is fixedly connected to the column 6 through the fastener 8. Then, the protective net is installed, thereby realizing the rapid installation of the foundation pit protection device.

[0030] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
