[0002] Excavation pit support, a crucial technical measure in the field of construction engineering, refers to a series of engineering methods and structural measures taken to ensure the stability and safety of the soil surrounding the excavation pit during underground structure construction. It mainly involves reinforcing, supporting, and draining the edges of the excavation pit to prevent landslides, collapses, or excessive deformation, thereby ensuring the safety of construction workers, protecting the surrounding environment, and ensuring the smooth construction of the underground structure.

[0003] However, the existing authorized publication number CN217517608U discloses a foundation pit perimeter retaining structure supported by steel sheet piles, belonging to the field of foundation pit protection engineering technology. The steel sheet pile support is installed around the perimeter of the foundation pit and includes: a structural frame fixedly installed on one side of the top of the steel sheet pile support; retaining components fixedly installed on the side of the structural frame and extending vertically to block personnel or objects on the ground around the foundation pit; and several installation components fixedly installed on the top of the steel sheet pile support to achieve fixed installation between the structural frame and the steel sheet pile support. The installation components include: an installation body, a first fixing member, and a second fixing member. This utility model, by connecting the retaining components and the steel sheet pile support into a whole, can greatly improve the rigidity and strength of the retaining components, thereby enhancing the safety and durability of the retaining structure.

[0004] While the above technical solutions can significantly improve the rigidity and strength of the enclosure components, thereby enhancing the safety and durability of the enclosure structure, most existing fences are assembled from multiple fence units using bolts, a time-consuming and labor-intensive method. Therefore, we offer a modular assembly support structure for foundation pit enclosures. Utility Model Content

[0005] The purpose of this utility model is to provide a modular assembly support structure for foundation pit enclosure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular assembly support structure for foundation pit protection, comprising a first pillar, a second pillar on one side of the first pillar, an assembly groove on the side of the first pillar away from the second pillar, an assembly block on the side of the second pillar away from the first pillar, installation grooves on opposite sides of the first and second pillars, uprights inside the first and second pillars, positioning strips on both outer sides of the two uprights, two fixing grooves on both outer sides of the two uprights, limit plates on the bottom side of the two uprights near the positioning strips, positioning grooves on both inner walls of the first and second pillars, tie rods in multiple slots in the first and second pillars, springs on the outside of the multiple tie rods, fixing blocks on the end of the multiple tie rods near the positioning grooves, a horizontal plate between the first and second pillars, connecting blocks at both ends of the horizontal plate, a protective net at the bottom of the horizontal plate, and fixing mechanisms at the bottom of the two uprights.

[0007] As a further preferred embodiment of this technical solution, the fixing mechanism includes a mounting plate, which is fixedly connected to the bottom end of the upright, and a pre-embedded drill bit is fixedly connected to the bottom of the mounting plate.

[0008] As a further preferred embodiment of this technical solution, the assembly block is connected to the assembly groove, and positioning strips are fixedly connected to both sides of the upright. The two uprights are respectively inserted into the slots opened in the first and second pillars.

[0009] As a further preferred embodiment of this technical solution, the outer side of the positioning strip is slidably connected to the inner wall of the positioning groove, and the limiting plate is fixedly connected to the outer side of the upright.

[0010] As a further preferred embodiment of this technical solution, one end of the pull rod passes through the inner ring of the spring and is fixedly connected to one end of the fixing block, and the other end of the fixing block is engaged with the fixing groove.

[0011] As a further preferred embodiment of this technical solution, both ends of the horizontal plate are fixedly connected to connecting blocks, and the two connecting blocks are respectively fixedly installed to the top of the two uprights by fixing bolts.

[0012] As a further preferred embodiment of this technical solution, a protective net is fixedly connected to the bottom of the horizontal plate, and the two sides of the protective net are respectively connected to two mounting slots.

[0013] This utility model provides a modular assembly support structure for foundation pit enclosure, which has the following beneficial effects:

[0014] (1) By pulling the pull rod provided on the support column, the fixing block can be squeezed against the spring. The upright is inserted into the support column by using the positioning groove and the positioning block. The support column can be limited by the limiting plate to prevent the support column from falling outside the upright. After the pull rod is released, the spring returns to its elasticity and pushes the fixing block to be locked in the fixing groove. Therefore, the upright and the support column will be fixedly limited. The connecting blocks at both ends of the horizontal plate are fixedly installed on the two uprights by fixing bolts. The guard net provided at the bottom of the horizontal plate will be installed between the first and second support columns. Multiple sets of guards can be assembled by using the assembly groove and assembly block, avoiding the traditional use of bolts to assemble and assemble multiple sets of fences.

[0015] (2) This utility model can penetrate deep into stable soil or rock layers through the pre-embedded drill bit, providing stronger pull-out resistance and overturning resistance, and is especially suitable for soft soil foundations or deep foundation pits. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, the modular assembly support structure for the foundation pit includes a first column 11, a second column 12 is provided on one side of the first column 11, an assembly groove 13 is provided on the side of the first column 11 away from the second column 12, an assembly block 14 is provided on the side of the second column 12 away from the first column 11, and installation grooves 15 are provided on the opposite sides of the first column 11 and the second column 12. Uprights 16 are provided inside both the first column 11 and the second column 12, and the outer sides of the two uprights 16 are... Each component is equipped with a positioning strip 17. The assembly block 14 mates with the assembly groove 13. Positioning strips 17 are fixedly connected to both sides of the upright 16. The two uprights 16 are respectively inserted into the slots opened in the first support column 11 and the second support column 12. Two fixing slots 18 are opened on both sides of the outside of the two uprights 16. Limiting plates 19 are provided on the bottom side of the outside of the two uprights 16 near the positioning strips 17. Positioning grooves 110 are opened on both sides of the inner wall of the first support column 11 and the second support column 12. The outside of the positioning strips 17 is connected to the positioning grooves 110. The inner wall is slidably connected, and the limiting plate 19 is fixedly connected to the outside of the upright 16. Multiple slots in the first pillar 11 and the second pillar 12 are each equipped with a pull rod 111. Springs 112 are installed on the outside of each pull rod 111. A fixing block 113 is installed at one end of each pull rod 111 near the positioning groove 110. One end of the pull rod 111 passes through the inner ring of the spring 112 and is fixedly connected to one end of the fixing block 113. The other end of the fixing block 113 is engaged with the fixing groove 18. The first pillar 11 and the second pillar... A horizontal plate 114 is provided between 12. A connecting block 115 is provided at both ends of the horizontal plate 114. The connecting block 115 is fixedly connected to both ends of the horizontal plate 114. The two connecting blocks 115 are fixedly installed to the top of the two uprights 16 by fixing bolts 116 respectively. A protective net 117 is provided at the bottom of the horizontal plate 114. The protective net 117 is fixedly connected to the bottom of the horizontal plate 114. The two sides of the protective net 117 are respectively connected to the two mounting grooves 15. A fixing mechanism 2 is provided at the bottom of the two uprights 16.

[0024] In this embodiment, when the foundation pit support is required, multiple sets of supports need to be assembled. The specific assembly operation requires pulling the tie rod 111 on the support column, which in turn causes the fixing block 113 to compress the spring 112. The upright 16 is then inserted into the support column using the positioning groove 110 and the positioning block. The limiting plate 19 limits the position of the support column, preventing it from falling outside the upright 16. After releasing the tie rod 111, the spring 112 regains its elasticity and pushes the fixing block 113 into the fixing groove 18. Therefore... The uprights 16 and the support columns will be fixedly positioned. After the first support column 11 and the second support column 12 are installed, the connecting blocks 115 at both ends of the horizontal plate 114 will be fixedly installed on the two uprights 16 by fixing bolts 116. The protective netting 117 at the bottom of the horizontal plate 114 will be installed between the first support column 11 and the second support column 12. Therefore, after assembling multiple sets of enclosures according to the above steps, multiple sets of enclosures can be assembled using the assembly slot 13 and the assembly block 14, thereby completing the assembly process of the foundation pit support.

[0025] like Figures 1-4 As shown, the fixing mechanism 2 includes a mounting plate 21, which is fixedly connected to the bottom end of the upright 16, and a pre-embedded drill bit 22 is fixedly connected to the bottom of the mounting plate 21.

[0026] In this embodiment, a pre-embedded drill bit 22 is provided at the bottom of the upright 16 of each support column. The pre-embedded drill bit 22 can penetrate into stable soil or rock layers, providing stronger pull-out resistance and overturning resistance, and is especially suitable for soft soil foundations or deep foundation pits.

[0027] This utility model provides a modular assembly support structure for foundation pit protection, and its specific working principle is as follows:

[0028] During the assembly of the foundation pit support, the uprights 16 of the support column are inserted into the preset positioning slots 110. By pulling the tie rod 111, the fixing block 113 is pressed down on the spring 112, forming a temporary elastic compression state. The limiting plate 19 is used to axially limit the support column to prevent it from slipping out of the uprights 16. After releasing the tie rod 111, the spring 112 rebounds and pushes the fixing block 113 into the fixing slot 18, realizing the rigid locking of the uprights 16 and the support column. Between the uprights 16 of two adjacent sets of support columns, the horizontal connection is completed by the connecting blocks 115 at both ends of the horizontal plate 114 and the fixing bolts 116. The protective net 117 at the bottom of the horizontal plate 114 is installed simultaneously to cover the gap between the support columns. After the above steps are repeated to complete the installation of a single set of support, multiple sets of support units are spliced ​​into a whole along the edge of the foundation pit through the interlocking structure of the splicing slot 13 and the splicing block 14, ensuring that the connection points of each set are tightly fitted to form a continuous and stable support system.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
