Description

Technical Field

[0001] The utility model relates to the technical field of pebble layer trench support, in particular to a pebble layer trench support device. Background Technique

[0002] When excavating long-distance pipelines in high-water-level sandy pebble strata, in order to ensure construction safety and efficiency, it is necessary to take careful support measures for the excavated trenches. The support measures aim to prevent the collapse of the trench side walls caused by the instability of the sandy pebble layer and the rising water level, and at the same time protect the safety of the surrounding environment and underground facilities.

[0003] In actual applications, the current support devices generally adopt the method of constructing a connection structure between two adjacent support plates and forming a stable support system by fastening these connection points. Due to the dense connection structures between the support plates, these complex connectors occupy a large space. When it is necessary to hoist a prefabricated pipeline into a narrow and obstacle-filled trench, these connection structures often become insurmountable obstacles, increasing the construction difficulty. For this reason, we provide a pebble layer trench support device. Content of the Utility Model

[0004] The utility model provides a pebble layer trench support device, which solves the technical problem that the dense connection structures between the support plates, these complex connectors occupy a large space. When it is necessary to hoist a prefabricated pipeline into a narrow and obstacle-filled trench, these connection structures often become insurmountable obstacles, increasing the construction difficulty.

[0005] The purpose and effect of a pebble layer trench support device of the utility model are achieved by the following specific technical means: A pebble layer trench support device includes two support plates. On one side of each of the two support plates close to each other, a top-holding assembly is provided. Each top-holding assembly includes a support block installed on the side of each support plate away from the trench. On the upper surface of each support block, a threaded rod is rotatably connected. On the outer surface of each threaded rod, a moving plate is threadedly connected. On one side of each moving plate away from the support plate, two top plates are hinged. At the bottom end of each top plate, a first fixing block is hinged. On each first fixing block, a first insertion rod is provided. On one side of each of the two support plates away from each other, a top pulling and holding assembly is provided.

[0006] Preferably, a set of stabilizing rods is slidably connected to each moving plate. The ends of the two sets of stabilizing rods away from each other are respectively connected to the sides of the two support plates close to each other.

[0007] Preferably, each of the top pulling components includes a set of pulling plates hinged to the side of each support plate close to the groove. Second fixing blocks are hinged to the ends of the two sets of pulling plates away from each other, and second insertion rods are provided on each of the second fixing blocks.

[0009] Preferably, slots are formed in the upper surface of each support plate, and baffles are inserted into the interior of each slot.

[0010] Preferably, reinforcing blocks are fixedly connected to the side surfaces of the two support plates close to each other, and reinforcing rods are slidably connected to each of the reinforcing blocks.

[0011] Beneficial effects:

[0012] 1.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] As shown in the attached Figure 1 to the attached Figure 4 figures: A pebble layer trench support device includes two support plates 1. A slot 5 is provided on the upper surface of each support plate 1, and a baffle 6 is inserted into the interior of each slot 5. The slot 5 can stably fix the baffle 6 to ensure that it can remain stable and immovable in various working environments. The baffle plate 6 will form a solid barrier for the pebbles, effectively preventing the pebbles from falling into the trench due to accidental rolling or vibration.

[0022] On one side of the two support plates 1 close to each other, a top holding assembly 2 is provided. Each top holding assembly 2 includes a support block 201 installed on the side of each support plate 1 away from the trench. A threaded rod 202 is rotatably connected to the upper surface of each support block 201. The support block 201 can support and fix the threaded rod 202, and a turning handle is installed at the top of the threaded rod 202, which is convenient for the staff to rotate the threaded rod 202.

[0023] A moving plate 203 is threadedly connected to the outer surface of each threaded rod 202. Two roof plates 204 are hinged to the side surface of each moving plate 203 away from the support plate 1. A first fixing block 205 is hinged to the bottom end of each roof plate 204. A first inserting rod 206 is arranged on each first fixing block 205. When the moving plate 203 moves up and down, it will drive the top end of the roof plate 204 to move, and at the same time, the bottom end of the roof plate 204 will also move synchronously, so that the specific contact position between the first fixing block 205 and the bottom wall of the groove can be flexibly adjusted, thus realizing the dynamic adaptation and precise positioning of the support structure. By inserting the first inserting rod 206 into the bottom of the groove to fix the roof plate 204, the roof plate 204 will form a resistance against the support plate 1. At the same time, enough space will be left between the two support plates 1, providing sufficient operating space for the staff to hoist and arrange pipelines in the narrow groove, greatly reducing the construction difficulty and complexity.

[0024] Reinforcing blocks 7 are fixedly connected to the side surfaces of the two support plates 1 close to each other. A reinforcing rod 8 is slidably connected to each reinforcing block 7. By firmly inserting the reinforcing rod 8 into the bottom of the groove, the structural support of the middle area at the bottom of the support plate 1 is strengthened, and the overall stability of the support plate 1 is significantly improved, enabling it to maintain a stable support posture in the face of various complex geological conditions and external pressures and effectively resisting possible deformation or displacement.

[0025] A group of stabilizing rods 207 are slidably connected to each moving plate 203. The ends of the two groups of stabilizing rods 207 away from each other are respectively connected to the side surfaces of the two support plates 1 close to each other. The stabilizing rods 207 not only enhance the anti-torsion ability of the moving plate 203 during the lifting process, but also effectively limit its unnecessary rotational freedom, ensuring that the moving plate 203 can perform a smooth and non-shaky lifting movement along the preset trajectory under any operating conditions, ensuring the smooth lifting of the moving plate 203.

[0026] Top pulling assemblies 3 are arranged on the side surfaces of the two support plates 1 away from each other. Each top pulling assembly 3 includes a group of pulling plates 301 hinged to the side surface of each support plate 1 close to the groove. Second fixing blocks 302 are hinged to the ends of the two groups of pulling plates 301 away from each other. A second inserting rod 303 is arranged on each second fixing block 302. By pulling the pulling plates 301, the second fixing block 302 can quickly and accurately come into close contact with the upper surface of the pebble layer. By precisely inserting the second inserting rod 303 into the pebble layer to reinforce the second fixing block 302, a pull on the support plate 1 is formed, effectively dispersing the vertical and lateral pressures borne by the support plate 1 and significantly enhancing its overall stability.

[0027] A group of equally spaced retaining bars 4 are fixedly connected to the bottom surface of each support plate 1. The retaining bars 4 can be accurately inserted into the pebble layer at the bottom of the groove, creating a solid barrier between the support plate 1 and the pebble layer. The retaining bars 4 effectively limit the space between the bottom end of the support plate 1 and the pebble layer, forming a stable blocking area that can prevent pebbles from accidentally falling from the bottom of the support plate 1 into the groove.

[0028] Working principle: During use, the support plate 1 is attached to the inner wall of the groove to resist the pebbles. Then, the threaded rod 202 is rotated to adjust the height of the moving plate 203. At the same time, the top plate 204 will drive the first fixing block 205 to move until the first fixing block 205 contacts the bottom wall of the groove. Then, the first insertion rod 206 is inserted into the bottom of the groove, and the top plate 204 will form a resistance against the support plate 1. Next, the pull plate 301 is pulled in sequence to make the second fixing block 302 contact the upper side of the pebbles, and then the second insertion rod 303 is inserted into the upper layer of the pebbles, which will apply a pulling force towards the outside of the groove to the top of the support plate 1. Enough space will be left between the two support plates 1, facilitating the staff to hoist and arrange the pipelines, reducing the construction difficulty.
