[0002] With the country's continuous improvement in the quality of building construction, the use of shallow cast-in-place piles is gradually increasing (such as the foundation of glass greenhouses). Cast-in-place pile foundations have strong adaptability, high bearing capacity, and little impact on the surrounding area during construction, and their proportion in foundation construction is increasing day by day.
[0003] In actual operation, the operator operates the hoist to move the rammer hammer upward. When it reaches a certain height, the rammer hammer falls into the pile hole to compact the concrete inside the pile hole. However, when the rammer hammer falls downward, due to the small opening of the shallow pipe pile hole, the rammer hammer is difficult to fall accurately into the pile hole, and it may also damage the pile hole. Utility Model Content
[0004] The purpose of this invention is to provide a shallow grouting pile foundation compaction device, which aims to solve the problem that the rammer hammer is difficult to accurately drop into the pile hole in the existing technology.

Connecting columns are installed at intervals on the left and right sides of the top of the ramming plate. A connecting plate is installed on the top of the connecting columns. A ramming connecting shaft is set on the top of the connecting plate. Limiting components are slidably installed on the outer circumference of the connecting columns. The limiting components enable the ramming plate to be stably lowered into the pile hole. The fixed plate is equipped with a buffer component, which is connected to the limiting component. The buffer component is used to reduce the impact force of the limiting component on the ground.

[0014] 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.
[0015] Please see Figure 1-4 The present invention provides the following technical solution: a shallow grouting pile foundation compaction device, comprising: a rammer plate 1, a pile hole baffle 10 and a fixing plate 2. The fixing plate 2 is spaced apart on the left and right at the opening of the pile hole. The pile hole baffle 10 is spaced apart on the left and right on the inner wall of the pile hole. The rammer plate 1 is located at one end opposite to the pile hole baffle 10. The rammer plate 1 has a similar function to a rammer hammer, compacting the soil inside the pile hole.
[0016] Connecting columns 11 are installed at intervals on the left and right sides of the top of the rammer plate 1. Connecting plates 12 are installed on the top of the connecting columns 11. A rammer connecting shaft 13 is set on the top of the connecting plate 12. The rammer connecting shaft 13 is connected to the rammer elevator (not shown in the figure). The rammer elevator can drive the rammer connecting shaft 13 to a certain height and then release the rammer connecting shaft 13. This is the existing technology and will not be described in detail here.
[0017] Please see Figure 1-4 A limiting component is slidably installed on the outer circumference of the connecting column 11. The limiting component allows the tamping plate 1 to fall stably into the pile hole. The tamping hoist releases the tamping connecting shaft 13, and the tamping plate 1 falls freely under the action of gravity. The limiting component allows the tamping plate 1 to fall smoothly and accurately into the pile hole, thereby compacting the soil inside the pile hole.
[0018] The limiting component includes a limiting plate 14, a sliding sleeve 15, and a limiting post 16. The limiting post 16 is installed on the top of the fixed plate 2. The limiting plate 14 is slidably disposed on the limiting post 16. The sliding sleeve 15 is spaced apart on the bottom of the limiting plate 14. The connecting post 11 passes through the sliding sleeve 15 and slides out of the top of the limiting plate 14.
[0019] Please see Figure 1-4 The hoist drives the rammer connecting shaft 13 to move upward. The rammer plate 1 moves upward through the sliding sleeve 15, which drives the limiting plate 14 to move upward. The limiting plate 14 slides on the limiting column 16. The rammer connecting shaft 13 is released. Under the action of gravity, the limiting plate 14 and the rammer plate 1 move downward at the same time. The limiting column 16 enables the limiting plate 14 to descend stably, and the sliding sleeve 15 and the connecting column 11 enable the rammer plate 1 to descend smoothly. Finally, the rammer plate 1 falls accurately into the pile hole.
[0020] The pile hole baffle 10 has a vertically penetrating groove 17 at one end, and a slider 18 is slidably installed inside the groove 17. The slider 18 is connected to the rammer plate 1. The rammer plate 1 can slide stably between the pile hole baffle 10 through the groove 17 and the slider 18.
[0021] The distance between the connecting plate 12 and the limiting plate 14 is greater than the depth of the pile hole to avoid the connecting plate 12 colliding with the limiting plate 14 due to insufficient length of the connecting column 11.
[0022] A buffer is provided on the fixed plate 2. The buffer is connected to the limiting member. The buffer is used to reduce the impact force of the limiting member on the ground. The buffer includes support plates 21 that are spaced apart on the fixed plate 2. A hydraulic buffer 22 is provided between two adjacent support plates 21. A buffer groove 23 is opened at one end of the two adjacent support plates 21. A buffer block 231 is slidably arranged inside the buffer groove 23. The buffer block 231 is connected to the limiting plate 14.
[0023] As the rammer plate 1 descends, the buffer block 231 falls into the buffer groove 23, and the hydraulic buffer 22 cushions the limiting plate 14, reducing the impact force of the limiting plate 14 on the ground and reducing the damage to the limiting plate 14. At the same time, the rammer plate 1 continues to fall until it lands inside the pile hole.
[0024] Please see Figure 1-4 Working principle: When in use, the rammer hoist is connected to the rammer connecting shaft 13. The rammer hoist drives the rammer connecting shaft 13 to rise until the rammer plate 1 leaves the pile hole. Then, the operator fills the pile hole with concrete and then releases the rammer connecting shaft 13. Under the action of gravity, the limiting plate 14 and the rammer plate 1 move downward at the same time. The limiting column 16 can make the limiting plate 14 descend stably, and the sliding sleeve 15 and the connecting column 11 can make the rammer plate 1 descend smoothly.
[0025] As the ramming plate 1 descends, the buffer block 231 falls into the buffer groove 23, and the hydraulic buffer 22 cushions the limiting plate 14, reducing the impact force of the limiting plate 14 on the ground and reducing the damage to the limiting plate 14. At the same time, the ramming plate 1 continues to fall until it accurately lands inside the pile hole, thereby compacting the concrete inside the pile hole.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.
