Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a combined anti-collapse device for water conservancy engineering construction. Background Technology

[0002] During the construction of water conservancy projects, especially during underground excavation, slope construction, foundation pit support, tunnel excavation and canal excavation, the stability of soil or rock masses is a particularly prominent issue. Due to complex hydrogeological conditions, frequent changes in groundwater levels, construction disturbances and external loads, the construction area is prone to safety accidents such as slope instability, loosening of surrounding rock and collapse of pit walls. These accidents not only affect the progress of the project, but also seriously threaten the lives of construction workers and the safety of equipment.

[0003] Traditional anti-collapse measures often employ single support methods, such as timber supports, steel arches, shotcrete and anchor supports, or retaining walls. While these methods can provide stability to some extent, they still have many limitations: for example, they have high structural rigidity and poor adaptability, making it difficult to cope with complex and changing geological conditions; the installation and dismantling process is cumbersome, resulting in low construction efficiency; and the material reuse rate is low, leading to resource waste and increased costs. However, some existing combined support structures still suffer from problems such as insufficient connection reliability and poor overall stability, especially in water-rich strata or weak surrounding rock conditions, where local failures can easily lead to overall instability.

[0004] Therefore, this utility model provides a combined anti-collapse device for water conservancy engineering construction. Utility Model Content

[0005] In order to overcome the shortcomings of traditional and existing combined anti-collapse support, such as high rigidity, poor adaptability, difficult installation and dismantling, low efficiency, high cost, unreliable connection and insufficient stability, this utility model provides a combined anti-collapse device for water conservancy engineering construction.

[0006] The present invention provides a combined anti-collapse device for water conservancy engineering construction, comprising a first support plate, a second support plate, a first pin rod, a second pin rod, a reinforcing plate, fixing screws, a third pin rod, a first connecting block, a second connecting block, and a connecting block. The second support plate is located on the left side of the first support plate. First pin rods are fixedly connected to the bottom of both the first and second support plates. Second pin rods are fixedly connected to the rear of both the first and second support plates. Reinforcing plates are located on the top of both the first and second support plates. Multiple fixing screws are provided on the top of each reinforcing plate. The reinforcing plates are connected to the corresponding first and second support plates via fixing screws. A third pin rod is fixedly connected to the bottom of each reinforcing plate. A first connecting block is fixedly connected to the front left side of both the first and second support plates. A second connecting block is fixedly connected to the front right side of both the first and second support plates. A connecting block is fixedly connected to the left side of each first connecting block.

[0007] In a preferred embodiment of the present invention, the device further includes a mounting plate, a mounting block, a sliding rod, a fixing block, and a spring. The mounting plate is fixedly connected to the left front part of the first support plate, and two mounting blocks are fixedly connected to the right front part of the second support plate. Two sliding rods are slidably connected to the upper and lower sides of the mounting plate. A fixing block is fixedly connected to the other end of each pair of adjacent sliding rods. A spring connects the fixing block and the mounting plate.

[0008] In a preferred embodiment of the present invention, a wave plate is also included, and a wave plate is fixedly connected to the left side of each fixed block.

[0009] In a preferred embodiment of this utility model, the docking block is designed in a cross shape.

[0010] In a preferred embodiment of this utility model, the first pin, the second pin, and the third pin are distributed sequentially from bottom to top.

[0011] In a preferred embodiment of this utility model, both the first support plate and the second support plate are made of low-alloy high-strength steel.

[0012] The beneficial effects of this utility model are as follows: 1. By setting a vertical snap-fit ​​between the docking block and the second connecting block between the first and second support plates, and the synchronous fitting of the fixing block and the mounting block, the two support plates can be quickly positioned and mechanically locked during the top-to-bottom installation process, which improves the assembly efficiency and connection reliability; 2. The first, second, and third pins are used to anchor the bottom, rear, and top reinforcement plates of the support plates at multiple points, which enhances the overall structure's resistance to overturning and slippage.

[0013] 2. By setting up a corrugated plate, sliding rod, spring and fixed block in linkage, the locking mechanism can be manually and quickly unlocked. The operator can push the corrugated plate inward to drive the fixed block to disengage from the installation block and release the mechanical lock between the support plates. No tools are needed and disassembly is convenient. This design makes the device have good disassembly and reusability, which significantly improves construction efficiency.

Detailed Implementation

[0019] 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.

[0020] Example: A combined anti-collapse device for water conservancy engineering construction, such as... Figures 1-4As shown, the system includes a first support plate 1, a second support plate 2, a first pin 3, a second pin 4, a reinforcing plate 5, fixing screws 6, a third pin 7, a first connecting block 8, a second connecting block 9, a mating block 10, a mounting plate 11, a mounting block 12, a sliding rod 13, a fixing block 14, a spring 15, and a wave plate 16. The second support plate 2 is located on the left side of the first support plate 1. Both the first and second support plates 1 and 2 are made of low-alloy high-strength steel. The bottom of both the first and second support plates 1 and 2 are fixedly connected to the first pin 3, and the rear of both are fixedly connected to the second pin 4. The top of both the first and second support plates 1 and 2 is provided with a reinforcing plate 5. Each reinforcing plate 5 has multiple fixing screws 6 on its top. The reinforcing plate 5 is connected to the corresponding support plate 1 and the second support plate via the fixing screws 6. The bottom is fixedly connected with a third pin 7. The first pin 3, the second pin 4 and the third pin 7 are distributed from bottom to top. The first support plate 1 and the second support plate 2 are fixedly connected with a first connecting block 8 on the front left side. The first support plate 1 and the second support plate 2 are fixedly connected with a second connecting block 9 on the front right side. Each first connecting block 8 is fixedly connected with a docking block 10 on the left side. The docking block 10 is designed in a cross shape to prevent it from falling off and to improve stability. The first support plate 1 is fixedly connected with a mounting plate 11 on the front left side. The second support plate 2 is fixedly connected with two mounting blocks 12 on the front right side. The mounting plate 11 has two sliding rods 13 slidably connected inside the upper and lower sides. Each pair of adjacent sliding rods 13 is fixedly connected with a fixing block 14 at the other end. A spring 15 is connected between the fixing block 14 and the mounting plate 11. Each fixing block 14 is fixedly connected with a wave plate 16 on the left side.

[0021] When this device is needed, the operator first places the two reinforcing plates 5 on top of the first support plate 1 and the second support plate 2 respectively, according to the construction requirements, and securely connects them with fixing screws 6 to enhance the overall strength of the support plates. Then, the first support plate 1 is aligned with the second support plate 2 and slowly lowered from top to bottom, allowing the mating block 10 at the bottom of the first support plate 1 to smoothly insert and engage with the second connecting block 9 on the second support plate 2. Simultaneously, the fixing block 14 on the first support plate 1 is also embedded in the corresponding mounting block 12 on the second support plate 2. Now, after locking and assembling, the operator inserts the first pin 3, the second pin 4, and the third pin 7 into the ground soil in sequence to ensure that the entire device is firmly anchored. When it is necessary to disassemble the device, the operator first pulls out the pins, and then manually pushes the two side wavy plates 16 inward to compress the internal spring 15 of the sliding rod 13, causing the fixing block 14 to disengage from the mounting block 12 and release the locking state. After the lock is released, the first support plate 1 is moved horizontally to the right to make the docking block 10 slide out from the second connecting block 9, completing the separation of the two support plates.
