Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, and in particular to an improved invention of a pile cap that can be used to drive cement piles. Background Technology

[0002] When constructing cement piles, pile pads need to be placed on top of the piles. Common types include paper pads and wooden pads. Existing pile caps include upper pile caps, replacement pile caps, and lower pile caps. The inner diameter of the lower pile cap is smaller than that of the upper pile cap, which helps to prevent the replacement pile from falling off. However, during the construction of cement piles, the top of the cement pile and the attached pile pad enter the upper pile cap through the lower pile cap. During the hammering process, the pile pad will expand, that is, the pile pad is flattened and its outer diameter becomes larger. Due to the limitation of the lower pile cap, it remains inside the upper pile cap and is difficult to remove. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pile cap that can be used for driving cement piles.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: The pile cap for driving concrete piles includes an upper pile cap, a replacement pile cap, and a lower pile cap. The replacement pile cap is movable up and down and matched within the upper pile cap. The top of the upper pile cap is provided with a hammering port. The lower pile cap forms a limit for the replacement pile cap to dislodge. The inner diameter of the lower pile cap is smaller than that of the upper pile cap. The feature is that the pile cap also includes a sleeve adapted to the concrete pile. The sleeve has a cylindrical cavity and a top plate. The sleeve is movable up and down, and its outer circle supports and cooperates with the inner circle of the lower pile cap. The top of the sleeve is located inside the upper pile cap and is limited between the lower end of the replacement pile cap and the upper end of the lower pile cap. The top of the sleeve has a limiting outer periphery.

[0005] The outer circle of the sleeve is provided with several circumferentially arranged ribs, which are supported on the inner circle of the lower pile cap.

[0006] The upper end of the substitute is fitted with a hammer pad.

[0007] The beneficial effect of this utility model is that the improved pile cap for driving cement piles is designed with a sleeve that is adapted to the cement pile. The sleeve has a straight cylindrical cavity and a top plate at the top, which effectively prevents the pile pad from expanding and makes it easy to remove the pile pad after use.

[0011] Figure 3 This utility model Figure 2 AA sectional view. Detailed Implementation

[0012] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-3 The pile cap for driving cement piles includes an upper pile cap 1, a replacement pile cap 2, and a lower pile cap 3. The upper pile cap 1 and the lower pile cap 3 are connected by a flange face. The upper pile cap 1 is provided with a lifting point 9. The replacement pile cap 2 can be moved up and down to match the upper pile cap 1. The top of the upper pile cap 1 is provided with a hammering port 4. The lower pile cap 3 forms a limit for the replacement pile cap 2 to come out. The inner diameter of the lower pile cap 3 is smaller than the inner diameter of the upper pile cap 1. The pile cap is also provided with a sleeve 5 adapted to the cement pile. The sleeve 5 has a straight cylindrical cavity. The top of the sleeve 5 is provided with a top plate. The sleeve 5 can be moved up and down. The outer circle of the sleeve 5 supports and cooperates with the inner circle of the lower pile cap 3. The top of the sleeve 5 is located inside the upper pile cap 1 and is limited between the lower end of the replacement pile cap 2 and the upper end of the lower pile cap 3. The top of the sleeve 5 has a limiting outer periphery 6. Preferably, the limiting outer periphery 6 is close to the inner circle of the upper pile cap 1.

[0013] The working principle of this utility model is that the sleeve 5 is placed inside the pile cap and can move up and down. It is limited by the lower pile cap 3 to prevent it from falling out. After the pile pad is placed and constructed, the straight cylindrical cavity of the sleeve 5 prevents the pile pad from expanding and makes it easy to remove the used pile pad.

[0014] For a further improved implementation method, see Appendix Figure 3 The sleeve 5 has several circumferentially arranged ribs 8 on its outer circle, which are supported on the inner circle of the lower pile cap 3 to enhance the structural strength of the sleeve 5.

[0015] For a further improved implementation method, see Appendix Figure 1 Alternatively, 3, the upper end of the substitute hammer 2 is embedded with a hammer pad 7, which mainly plays the role of uniformly transmitting stress during the hammering of the precast pile.

[0016] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
