Description

A trench excavation support device Technical Field

[0001] This utility model relates to the field of support device technology, specifically a trench excavation support device. Background Technology

[0002] After excavation, the natural stress balance is disrupted, and the interaction of lateral earth pressure and groundwater can easily trigger collapses, landslides, or piping, threatening construction safety and the surrounding environment. Therefore, it is necessary to install support devices on the trench sidewalls during trench excavation to protect the construction site and ensure safety.

[0003] Existing trench excavation support devices typically employ baffles and diagonal braces fixedly combined on-site to form a support system. This traditional structural support system has shortcomings. The on-site support environment is variable; some locations may be high in height, or temporary heightening may be required during construction. Consequently, the height of the support device must be raised accordingly. Traditional support devices have a fixed height, making it inconvenient to quickly raise the support device. Raising the height requires the use of new support baffles for secondary support, which is cumbersome and inconvenient. Therefore, it cannot meet the need for rapid on-site heightening of support. To address the shortcomings of existing technologies, this utility model provides a trench excavation support device to solve the above problems. Summary of the Invention

[0027] 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 scope of protection of the present utility model. Embodiments

[0028] Please refer to Figures 1-4. This utility model provides a technical solution: a trench excavation support device, including a foundation support baffle 1, a connecting plate 2, a diagonal brace 3, a heightening baffle 4, a locking plate 5, and a locking mechanism 6.

[0029] The basic support baffle 1, as the foundation of the entire support device, is set at the target location to provide initial support for the trench sidewalls. It has a limiting groove 11 for inserting the insert plate 41 on the heightening baffle 4.

[0030] The connecting plate 2 is set on the back of the foundation support baffle 1 to provide a connection point for the diagonal brace 3 and enhance the stability of the support device.

[0031] The diagonal brace 3 is installed between the connecting plate 2 and the ground to provide diagonal support for the foundation support baffle 1, preventing the baffle from tilting or shifting due to soil pressure.

[0032] The heightening baffle 4 is movably latched above the foundation support baffle 1, allowing for rapid increases in support height as needed. The heightening baffle 4 has a movable insert plate 41 that latches into the limiting groove 11. The foundation support baffle 1 has reinforcement holes 12, and the heightening baffle 4 has reinforcement columns 42 that are movably inserted into the reinforcement holes 12.

[0033] The locking plate 5 is installed inside the foundation support baffle 1 and cooperates with the locking mechanism 6 to form a locking and limiting state, preventing the heightening baffle 4 from loosening or falling off during use. The locking plate 5 has several sets of locking holes 51 corresponding to the positions of the locking rods 63 on the locking mechanism 6.

[0034] The locking mechanism 6 is mounted on the insert plate 41 and is used to form a locking and limiting state with the locking plate 5. The locking mechanism 6 includes a guide rail frame 61, an adjusting block 62, and several sets of locking rods 63. The guide rail frame 61 is mounted on the insert plate 41 and provides a sliding track for the adjusting block 62; the adjusting block 62 is mounted on the guide rail frame 61 and can slide along the guide rail frame 61; several sets of locking rods 63 are mounted on the adjusting block 62 and are movably engaged inside the locking plate 5. The locking of the heightening baffle 4 is achieved through the cooperation of the locking rods 63 and the locking holes 51.

[0035] Furthermore, a lead screw 64 is threadedly connected to the guide rail frame 61. The lead screw 64 is rotatably connected to the adjusting block 62. A rotating handle 65 is provided on the lead screw 64. By rotating the rotating handle 65, the lead screw 64 can be rotated, thereby driving the adjusting block 62 to slide along the guide rail frame 61, so as to realize the insertion or removal of the locking rod 63.

[0036] When using this trench excavation support device:

[0037] Step 1: Install foundation support baffle 1:

[0038] The basic support baffle 1 is precisely placed at the predetermined position on the sidewall of the target trench, and its vertical stability is ensured through horizontal calibration and bottom compaction. Temporary anchors are used to pre-fix the bottom of the baffle, and the fit between the baffle and the trench wall is checked to avoid gaps that could lead to support failure.

[0039] Step 2: Install diagonal brace 3:

[0040] Secure the diagonal brace 3 to the mating plate 2 on the back of the foundation support baffle 1 with high-strength bolts to ensure that there is no looseness at the connection. Secure the diagonal brace 3 to the ground with expansion bolts or embedded parts to form a rigid fixation with the ground. After installation, use a torque wrench to check the bolt tightening torque and check whether the diagonal brace 3 has elastic deformation.

[0041] Third, depending on the actual needs of the site, a heightening baffle 4 can be installed:

[0042] Insert the bottom insert plate 41 of the heightening baffle 4 vertically along the limiting groove 11 at the top of the foundation support baffle 1, and simultaneously align and embed the reinforcing column 42 of the heightening baffle 4 into the reinforcing hole 12 at the top of the foundation support baffle 1. Gently tap the top of the heightening baffle 4 with a rubber mallet to ensure it is inserted in place, and eliminate installation gaps with anti-slip pads.

[0043] Step 4: Lock and tighten the heightening baffle 4.

[0044] By rotating the handle 65 of the locking mechanism 6, the lead screw 64 is driven to spirally advance within the guide rail frame 61, causing the adjusting block 62 to translate axially along the guide rail, so that the locking rod 63 is precisely inserted into the locking hole 51 of the locking plate 5.
