Description

Technical Field

[0001] The utility model relates to the technical field of manual dug piles, in particular to a water stop structure for manual dug piles. Background Art

[0002] In river or riverbank areas, the river beach covering layer in the area adjacent to the main river channel is often thin and has strong water permeability. The rock surface in the shoal area is often high. When using pile foundations, the rock penetration depth is large. When using mechanical drilling technology, affected by the rock penetration depth and rock hardness, the construction progress is slow and the construction period cannot be guaranteed. Usually, the hole-forming technology of manual hole digging and rock blasting is adopted. However, when using manual dug piles, the problem of serious water accumulation in the hole during construction, which leads to impossible construction, will be faced.

[0003] After retrieval, a water stop structure for manual dug piles disclosed in a Chinese patent with the publication number CN213805351U. This device is provided with a first cylinder, an annular groove, an annular plate, a second cylinder, an annular groove and a clamping ring, which facilitates the first cylinder to be clamped on the second cylinder through the clamping ring at the bottom. At the same time, the surface of the second cylinder is inserted into the lower surface of the first cylinder through the annular plate to extend the gap and reduce water seepage, so as to achieve the effects of water stop and convenient connection of the manual dug pile.

[0004] However, the above patent still has deficiencies. In the process of implementing the technical solution of the above patent, there is no interaction force between the clamping groove and the clamping ring, so the sealing effect between the clamping groove and the clamping ring cannot be guaranteed. Existing manual dug piles will connect multiple cylinders to achieve the water stop effect, and the connection of multiple cylinders only uses simple insertion, so there is no interaction force between two adjacent cylinders, resulting in small gaps between two adjacent cylinders, leading to poor water stop effect. Therefore, a water stop structure for manual dug piles is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a water stop structure for manual dug piles. By setting a connecting ring, an assembling mechanism and a sealing mechanism, the water stop ring can be inserted into the water stop groove and extruded when two splicable cylinders are connected, so as to ensure the sealing performance of the connection between the two splicable cylinders, and further enhance the overall water stop effect of the structure.

[0006] The technical solution for achieving the object of the present utility model is: an artificial dug pile water stop structure, including a splicable cylinder, a connecting ring is arranged inside the splicable cylinder, a water stop ring is fixedly connected to the upper surface of the splicable cylinder, a water stop groove is opened at the bottom surface of the splicable cylinder, four assembling mechanisms are arranged inside the splicable cylinder, and the assembling mechanism includes a clamping block fixedly connected to the bottom surface of the connecting ring and a clamping seat fixedly connected to the inner wall of the splicable cylinder, and the clamping block is adapted to the clamping seat. A sealing mechanism is arranged inside the splicable cylinder, and the sealing mechanism includes a toothed ring and a plurality of threaded rods rotatably connected to the upper surface of the connecting ring. Threaded moving blocks are threadedly connected to the outer surfaces of the plurality of threaded rods, and the plurality of threaded moving blocks are fixedly connected to the inner wall of the splicable cylinder.

[0007] In some embodiments, a sealing gasket is fixedly connected to the outer surface of the water stop ring, and the water stop ring is adapted to the water stop groove.

[0008] In some embodiments, a spring is fixedly connected to the outer surface of the clamping seat, and one end of the spring away from the clamping seat is fixedly connected to an operation disc.

[0009] In some embodiments, a limiting rod is fixedly connected to one side surface of the operation disc close to the clamping seat. The limiting rod penetrates through the clamping seat and is slidably connected to the clamping seat, and the limiting rod is adapted to the clamping block.

[0010] In some embodiments, gears are fixedly connected to the tops of the plurality of threaded rods, and the plurality of gears are meshed with the toothed ring.

[0011] In some embodiments, a rotating ring is fixedly connected to the bottom surface of the toothed ring, and a sliding seat is slidably connected to the outer surface of the rotating ring. The sliding seat is fixedly connected to the upper surface of the connecting ring.

[0012] Compared with the prior art, the present utility model has the following remarkable advantages:

[0013] First: Through the settings of the splicable cylinder, the connecting ring, the assembling mechanism and the sealing mechanism, the present utility model can insert the water stop ring into the water stop groove and extrude it when two splicable cylinders are connected, so as to ensure the sealing performance of the connection between the two splicable cylinders. Compared with the simple insertion of two splicable cylinders in the prior art, the sealing effect of the connection can be ensured, thereby ensuring the water stop effect of the splicable cylinder.

[0014] Second: With the setting of the assembly mechanism of the present utility model, when two splicable cylinders are connected, pull the operation disc on the lower splicable cylinder to pull out the limiting rod from the clamping seat. At this time, the spring will be stretched. Insert the clamping block of the upper splicable cylinder into the clamping seat of the lower splicable cylinder, and then release the operation disc. Under the elastic force of the spring, push the limiting rod into the clamping block of the upper splicable cylinder, thereby completing the fixation of the connecting ring, facilitating the subsequent connection of the two splicable cylinders.

[0015] It solves the problem in the prior art that there is no interaction force between the clamping groove and the clamping ring, so that the sealing effect between the clamping groove and the clamping ring cannot be guaranteed. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a water stop structure for manually dug piles through improvement. The technical solution of the present utility model is:

[0025] As shown Figure 1 in the figure, a water-stop structure for manually dug piles includes a splicable cylinder 1. A connecting ring 2 is arranged inside the splicable cylinder 1. A water-stop ring 5 is fixedly connected to the upper surface of the splicable cylinder 1. A water-stop groove 6 is formed in the bottom surface of the splicable cylinder 1. Four assembling mechanisms 3 are arranged inside the splicable cylinder 1. The assembling mechanism 3 includes a clamping block 31 fixedly connected to the bottom surface of the connecting ring 2 and a clamping seat 32 fixedly connected to the inner wall of the splicable cylinder 1. The clamping block 31 is adapted to the clamping seat 32. A sealing mechanism 4 is arranged inside the splicable cylinder 1. The sealing mechanism 4 includes a toothed ring 41 and a plurality of threaded rods 42 rotatably connected to the upper surface of the connecting ring 2. The outer surfaces of the plurality of threaded rods 42 are all threadedly connected with internal-thread moving blocks 43. The plurality of internal-thread moving blocks 43 are all fixedly connected to the inner wall of the splicable cylinder 1.

[0026] As shown Figure 2 and Figure 3 in the figure, in one embodiment, a sealing gasket is fixedly connected to the outer surface of the water-stop ring 5. The water-stop ring 5 is adapted to the water-stop groove 6. The cross-sections of the water-stop ring 5 and the water-stop groove 6 are both conical, and the height of the water-stop ring 5 is slightly greater than the depth of the water-stop groove 6.

[0027] In one embodiment, a spring 33 is fixedly connected to the outer surface of the clamping seat 32. One end of the spring 33 away from the clamping seat 32 is fixedly connected to an operation disc 34. The arrangement of the spring 33 can prevent the limiting rod 35 from disengaging from the clamping block 31.

[0028] In one embodiment, a limiting rod 35 is fixedly connected to one side surface of the operation disc 34 close to the clamping seat 32. The limiting rod 35 penetrates through the clamping seat 32 and is slidably connected to the clamping seat 32. The limiting rod 35 is adapted to the clamping block 31. When the limiting rod 35 is inserted into the clamping block 31, it can fix the clamping block 31 and the clamping seat 32.

[0029] As shown Figure 4 in the figure, in one embodiment, the tops of the plurality of threaded rods 42 are all fixedly connected with gears 44. The plurality of gears 44 are all meshed with the toothed ring 41. When the toothed ring 41 rotates, under the meshing action of the toothed ring 41 and the gears 44, it can drive the plurality of threaded rods 42 to rotate synchronously.

[0030] In one embodiment, a rotating ring 45 is fixedly connected to the bottom surface of the toothed ring 41. The outer surface of the rotating ring 45 is slidably connected with a sliding seat 46. The sliding seat 46 is fixedly connected to the upper surface of the connecting ring 2. The sliding between the rotating ring 45 and the sliding seat 46 plays a supporting role for the rotation of the toothed ring 41.

[0031] The specific working method is as follows: when the manual dug pile water-stop structure is used, first place the splicable cylinder 1 into the pit, then place another splicable cylinder 1 into the pit, so that the clamping block 31 of the upper splicable cylinder 1 is connected to the clamping seat 32 of the lower splicable cylinder 1. At this time, the water-stop ring 5 of the lower splicable cylinder 1 is inserted into the water-stop groove 6 of the upper splicable cylinder 1. Then, turn the toothed ring 41. Under the meshing action of the toothed ring 41 and the gear 44, drive the multiple threaded rods 42 to rotate synchronously, thereby driving the upper splicable cylinder 1 and the internally threaded moving block 43 to move downward. The water-stop groove 6 of the upper splicable cylinder 1 will squeeze the water-stop ring 5 of the lower splicable cylinder 1 and the sealing gasket on the surface of the water-stop ring 5, so that the two splicable cylinders 1 are squeezed and sealed. This device can insert the water-stop ring 5 into the water-stop groove 6 and squeeze it when the two splicable cylinders 1 are connected, so as to ensure the sealing performance of the connection between the two splicable cylinders 1.
