Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a deep foundation pit support structure in silty soil strata. Background Technology

[0002] The main functions of deep foundation pit support structures in silty strata include retaining soil, blocking water, and preventing pit wall collapse, ensuring the safe and smooth progress of foundation pit excavation and foundation construction, while protecting adjacent buildings, roads and underground pipelines from damage.

[0003] Chinese patent CN213978979U discloses an ultra-deep foundation pit support structure, including a device body. Support rods are symmetrically connected to the left and right sides of the top of the device body. A fixed seat is fixedly connected to the top of each support rod, and a fixed rod is fixedly connected to the center of the top of each fixed seat. A rotating shaft is located in the center of the front of each fixed rod, and a chain disc is located in the center of the rotating shaft. A chain is provided on the surface of the chain disc. A movable block is located on the opposite side of each support rod. A third groove is formed around the inner wall of a first support pile, which is inserted into a second support column. A second locking block is fixedly connected around the inner wall of the second support column. In this ultra-deep foundation pit support structure, after the servo motor is started, the second support column slides down from the third groove on the surface of the first support pile. When the desired depth is reached, the bottom of the second support column is fixed at the first groove on the surface of the device body, thus achieving fixation and effectively changing the excavation depth.

[0004] After the installation of the support structure is completed, the staff usually need to detect the depth of the deep foundation pit in the silty stratum. Usually, this needs to be done by manual measurement, which is a tedious process and has certain safety risks. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a deep foundation pit support structure in silty strata, including baffles 1, and an adjustment component 2 is provided between the two baffles 1;

[0025] An L-shaped plate 3 is fixedly installed on the top of one of the baffles 1. A drive motor 4 is fixedly installed on one side of the L-shaped plate 3. A winding wheel 5 is fixedly installed at the output end of the drive motor 4. The winding wheel 5 is rotatably connected to the inner wall of the L-shaped plate 3. A measuring ruler 6 is wound around the outer end of the winding wheel 5. A counterweight 7 is fixedly installed at the bottom of the measuring ruler 6. A support component 8 is provided on one side of both baffles 1, and a reinforcing component 9 is symmetrically provided on the inner side of both baffles 1.

[0026] The drive motor 4 drives the winding wheel 5 to rotate, thereby enabling the winding operation of the measuring ruler 6. The length of the measuring ruler 6 can be precisely controlled through adjustment. The counterweight 7 moves the measuring ruler 6 vertically downwards to facilitate the measurement of the depth of deep foundation pits in silty soil strata. This process greatly facilitates subsequent construction work and expands the application range of deep foundation pit support structures in silty soil strata.

[0027] Please see Figure 1 , Figure 2 and Figure 5 The adjustment component 2 includes a storage block 21. Two storage blocks 21 are symmetrically fixedly installed on the inner side of one of the baffles 1. An adjustment block 22 is slidably connected inside each of the two storage blocks 21. A fixing groove 23 is opened on the top of the two adjustment blocks 22. A lead screw 24 is fixedly installed inside the storage block 21. A fixing nut 25 is symmetrically threaded to the outer end of the lead screw 24. One of the fixing nuts 25 is located inside the fixing groove 23.

[0028] This structure allows for adjustment of the spacing between the two baffles 1, facilitating the adjustment of the width of the foundation pit support structure and enabling the equipment to construct foundation pits of varying widths in silty soil layers.

[0029] Please see Figure 1 and Figure 2 The support assembly 8 includes a support plate 81. Two support plates 81 are symmetrically fixedly installed on one side of the baffle 1, and multiple sub-fixing plates 82 are fixedly installed on one side of each of the two support plates 81. Each sub-fixing plate 82 has a ground pin 83 passing through its interior.

[0030] This structure can fix the outer end of the support structure, making the support structure more stable and providing better protection for deep foundation pits in silty soil strata.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The reinforcing component 9 includes a C-shaped seat 91, each C-shaped seat 91 is fixedly installed on the inner side of the baffle 1, and each C-shaped seat 91 has a threaded rod 92 passing through its interior. The outer end of each threaded rod 92 is movably connected to a reinforcing plate 93. The outer end of the threaded rod 92 is symmetrically threaded with a positioning nut 94. Every two positioning nuts 94 are located at the outer end of the C-shaped seat 91. The bottom of the reinforcing plate 93 is fixedly installed with a base 95, and a reinforcing pin 96 is fixedly installed on one side of each base 95.

[0032] This structure can support the inner side of the baffle 1, which can increase the stability of the support structure and make it safer for workers to carry out construction on the inner wall of the deep foundation pit in the silty soil layer.

[0033] Working principle: The worker pulls the adjusting block 22, which in turn adjusts another baffle 1. Both baffles 1 are adjusted to match the width of the deep foundation pit in the silty soil layer. The fixing nuts 25 are then rotated to secure the adjusting block 22. The baffle 1 is placed on the inner wall of the deep foundation pit in the silty soil layer. The ground pin 83 is inserted above the ground surface of the deep foundation pit in the silty soil layer. Then, the reinforcing plate 93 is rotated, which in turn adjusts the base 95. The base 95 is adjusted to the required position, and then the reinforcing pin 96 is used to secure the base 95. To fix the reinforcement plate 93, rotate the positioning nut 94 and use the positioning nut 94 to fix it. When it is necessary to measure the depth of the deep foundation pit in the silty stratum, start the drive motor 4. The drive motor 4 drives the winding wheel 5 to rotate. The winding wheel 5 drives the measuring ruler 6 to adjust. The measuring ruler 6 drives the counterweight 7 to adjust downward. Adjust the counterweight 7 to the bottom of the deep foundation pit in the silty stratum and use the measuring ruler 6 to detect the depth. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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.
