[0002] In trench excavation, traditional sheet pile support systems are susceptible to groundwater and heavy rains in complex geological conditions and loose soil environments. Furthermore, traditional fixed supports require repeated disassembly and reassembly, leading to extended construction periods and high material wastage rates. Operation of large equipment is restricted in confined spaces, and the overlapping of support structure and pipeline installation processes increases the risk of collisions and wear on connectors due to frequent disassembly and reassembly. Fixed support structures also obstruct working space, making it impossible to synchronize support and pipeline installation using traditional methods. Additionally, soil settlement causes support deformation that workers may not perceive during construction, posing safety hazards. Utility Model Content

[0003] This utility model provides a steel sheet pile device for trench support. The interlocking of the grooves on both sides of the baffle enhances the overall waterproofness and resists the infiltration of groundwater and rainwater. The support mechanism can flexibly adjust its length by means of the hydraulic extension and retraction of the support cylinder, which can adapt to trenches of different widths without repeated disassembly and assembly, thus meeting the pipeline installation space requirements. The detection mechanism on the bottom support mechanism monitors the deformation of the baffle in real time through the probe. When the deformation exceeds the safe range, the weak link of the locking rod breaks and triggers the buzzer alarm, improving construction safety.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel sheet pile device for trench support, comprising: multiple baffles, each with a buzzer; a crossbeam connecting the multiple baffles to form an integral structure; a support mechanism connecting the crossbeam and the bottom support mechanism to provide support force; and a bottom support mechanism located at the bottom of the device, on which a detection mechanism is provided.

A second fixing bracket 502 is provided on the second fixing block 5, and the second fixing bracket 502 is connected to the first fixing bracket 402 by a fixing rod nut 503 and a fixing rod 403. The crossbeam 2 is fixed between the first fixing block 4 and the second fixing block 5 by the fixing rod 403 and the fixing nut 503. Grooves are cut on both sides of the crossbeam 2 to fix support vertical beams 301, and the support rods 302 are fixed to the crossbeam 2 through crossbeam holes 201. One side of the supporting vertical beam 301 is connected to the horizontal beam 2, and the other side is connected to the supporting hydraulic cylinder 303 through the hydraulic cylinder fixing bolt 304. The supporting vertical beam 301 has a slot in the middle to connect the supporting rod 302. One side of the supporting hydraulic cylinder 303 is connected to the supporting vertical beam 301, and the other side is connected to the bottom supporting mechanism 7 through the base fixing bolt 718.

[0018] The detection mechanism 701 is connected to the bottom support mechanism 7 via a locking wheel fixing rod 708. The detection mechanism 701 is connected to a torsion spring 704 via a first spring fixing block 705. The torsion spring 704 is connected to the bottom support mechanism 7 via a second spring fixing block 719. A locking wheel 702 is fixed in the middle of the locking wheel fixing rod 708. A pin spring 706 is provided at the bottom of the detection mechanism 701. The detection mechanism 701 is connected to a pin 703 via the pin spring 706. A push button 704 is provided on the pin 703. A probe rod 713 is connected to one side of the detection mechanism 701 via a probe rod fixing bolt 716. The probe rod 713 is fixed to a probe base 714 via a probe base fixing bolt 717. A probe probe 715 is provided on the probe base 714. A probe spring 712 is provided on the probe rod 713. The testing mechanism 701 has an intermediate fixing frame 709 on one side. The intermediate fixing frame 709 is connected to the pin locking rod 711 through the intermediate fixing rod 710. The pin locking rod 711 is connected to the probe fixing base 714 on one side.

[0019] In this embodiment, the baffle 1 serves as the core barrier component of the trench support. Its main function is to prevent sand and soil from flowing into the working space. The baffle 1 has strip grooves on both sides, and the grooves of adjacent baffles can interlock with each other. The tight fit enhances the overall waterproofness and effectively resists the infiltration of groundwater and rainwater. The surface of the baffle 1 has multiple screw holes for connecting the first fixing block 4 and the second fixing block 5, and a buzzer 6 is fixed on it for deformation warning.

[0020] Crossbeam 2 and fixing components: Crossbeam 2 is a long strip steel structure used to connect multiple baffles 1 into a whole, improving the stability of the support. The first fixing block 4 is fixed to the baffle 1 by the first fixing bolt 401, and the second fixing block 5 is fixed to the baffle 1 by the second fixing bolt 501; the first fixing bracket 402 on the first fixing block 4 and the second fixing bracket 502 on the second fixing block 5 are locked by the fixing rod 403 and the fixing rod nut 503, thereby clamping and fixing the crossbeam 2 to the baffle 1. The two ends of the crossbeam 2 are provided with slots that fit the baffle 1, and multiple crossbeam holes 201 are distributed in the middle. The diameter of the crossbeam holes 201 matches the support rod 302. Grooves are opened on both sides of the edge for fixing the support rod 302 and the supporting vertical beam 301, respectively.

[0021] Support Mechanism 3: Support mechanism 3 includes a support vertical beam 301, a support rod 302, a support cylinder 303, and a cylinder fixing bolt 304. The support vertical beam 301 is a vertical steel structure, with one side embedded in the side groove of the crossbeam 2 for fixation, and the other side connected to the cylinder body of the support cylinder 303 via the cylinder fixing bolt 304. A through groove adapted to the support rod 302 is opened in the middle of the support vertical beam 301. The two ends of the support rod 302 are respectively inserted into the crossbeam hole 201 of the crossbeam 2 and the through groove of the support vertical beam 301, enhancing the connection rigidity between the crossbeam 2 and the support vertical beam 301. The piston rod end of the support cylinder 303 is connected to the bottom support mechanism 7 via a base fixing bolt 718. The overall length of the support mechanism 3 can be adjusted by hydraulic telescoping to adapt to pipe trenches of different widths, meeting the pipeline installation space requirements without disassembly.

[0022] Bottom support mechanism 7: It serves as the force base of support mechanism 3. It is connected to detection mechanism 701 through locking wheel fixing rod 708. Locking wheel 702 is welded and fixed in the middle of locking wheel fixing rod 708. Multiple locking holes are evenly distributed on the surface, which are adapted to the pin 703. Detection mechanism 701 is connected to one end of torsion spring 704 through first spring fixing block 705. The other end of torsion spring 704 is connected to bottom support mechanism 7 through second spring fixing block 719. The elastic force of torsion spring 704 can keep detection mechanism 701 in contact with baffle 1.

[0023] The detection mechanism 701 has a pin spring 706 at its bottom. A pin 703 passes through the pin spring 706 and is slidably connected to the detection mechanism 701. A push button 707 is fixed to the top of the pin 703. Pushing the push button 707 allows the pin 703 to be inserted into the locking hole of the locking wheel 702, thereby locking the position of the detection mechanism 701. In its natural state, the pin spring 706 can push the pin 703 to reset. One side of the detection mechanism 701 is connected to a probe rod 713 by a probe rod fixing bolt 716. A probe spring 712 is sleeved on the probe rod 713. Both ends of the probe rod 713 abut against the detection mechanism 701 and the probe base 714, respectively. The bottom end of the probe rod 713 is fixed to the probe base 714 by a probe base fixing bolt 717. A probe probe 715 is installed at the bottom of the probe base 714. The testing mechanism 701 has an intermediate fixing frame 709 welded on one side. The intermediate fixing frame 709 is hinged to the pin locking rod 711 via an intermediate fixing rod 710. The other end of the pin locking rod 711 is hinged to the probe base 714. The pin locking rod 711 has a weak link in the middle and is electrically connected to the buzzer 6 via a signal line.

[0024] Working principle: Outside the construction area, the first fixing block 4 and the second fixing block 5 are pre-installed through the screw holes on the baffle 1. After the baffle 1 is lowered into the trench, the construction personnel place the crossbeam 2 between the first fixing block 4 and the second fixing block 5, and quickly connect the crossbeam 2 and the baffle 1 by tightening the fixing rod 403 and the fixing nut 503. By inserting the support mechanism 3 into the groove of the crossbeam 2, and simultaneously installing the support rod 302 in the through groove of the crossbeam hole 201 and the support vertical beam 301, a rigid connection between the crossbeam 2 and the support mechanism 3 is completed. The support cylinder 303 changes its length through hydraulic extension and retraction, driving the bottom support mechanism 7 to abut against the baffle 1 on the other side, completing the trench support installation.

[0025] When the pipeline installation interferes with the support mechanism 3, the fixed position of the support rod 302 in the crossbeam hole 201 is adjusted, which drives the support vertical beam 301 and the support cylinder 303 to fold, releasing the working space and enabling the support mechanism 3 to be installed simultaneously with the pipeline installation without disassembly.

[0026] After the trench support is installed, the position of the detection mechanism 701 is rotated so that the probe 715 of the detection mechanism 701 is in close contact with the surface of the baffle 1. The push button 707 is pushed, which drives the pin 703 to move towards the locking wheel 702, so that the pin 703 is inserted into the locking wheel 702. At the same time, the pin locking rod 711 is engaged in the groove on the pin 703, so that the pin 703 is locked, thus completing the fixation of the position of the detection mechanism 701. When soil settlement causes slight deformation of baffle 1, probe 715 pushes probe base 714 to move, causing pin locking rod 711 to rotate around intermediate fixing rod 710, disengaging it from the groove of pin 703. Pin 703 rebounds under the action of pin spring 706, and detection mechanism 701 resets under the action of torsion spring 704. Construction personnel can judge the deformation by observing the status of detection mechanism. If the deformation is too large and the pin locking rod 711 cannot be lifted, its weak point will break, and the signal line will trigger buzzer 6 to alarm, forcibly warning of risk.
