Description

Technical Field

[0001] This utility model relates to the field of pile driving technology, specifically to a static pile driving machine for building engineering. Background Technology

[0002] A static pile driver is a pressure device specifically used for pile foundation construction in building engineering. It uses a hydraulic system to slowly and evenly press precast piles into the foundation in a static manner, avoiding the vibration, noise, and environmental pollution problems caused by traditional pile driving methods. It is particularly suitable for urban areas, bridges, and engineering environments with strict requirements for construction disturbance. It is highly adaptable and is one of the essential pieces of equipment in modern foundation engineering.

[0003] However, existing pile driving equipment is often constrained by the stability of the base when transmitting pressure in the soil, resulting in insufficient pile driving efficiency. Especially when the soil is relatively soft, the fixation of the base plate is prone to failure, and the pressure plate may shake or shift during the pressing process, affecting the verticality of the pile and the pile driving effect. Therefore, a more stable anchoring mechanism is needed to improve the pressure transmission efficiency in the soil and ensure the stable pile driving. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this utility model is to provide a static pile driver for building construction, which can use a hydraulic press to drive the pressure plate downward to press the movable cone into the soil layer during the installation of the base plate, thereby achieving stable anchoring of the base plate and improving the overall fixing strength and reliability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a static pile driver for building construction, comprising a base plate, a support frame installed on the top of the base plate, a hydraulic press installed on the top of the support frame, a piston rod of the hydraulic press passing through the support frame and fixedly connected to a pressure plate, a circular groove provided on the top of the base plate, a pile hole provided on the circular groove, a plurality of countersunk holes distributed circumferentially on the circular groove, a movable cone passing through the interior of the countersunk holes, and the cross-section of the movable cone being a continuous trapezoid from top to bottom.

[0007] Preferably, the bottom of the base plate is symmetrically fixedly connected to two fixing plates, and the bottom of the fixing plates is provided with two sets of anti-slip grooves.

[0008] Preferably, a hydraulic support is mounted on the top of the support frame, and the hydraulic press is located inside the hydraulic support.

[0009] Preferably, the top of the base plate is symmetrically fixed with four fixed cones.

[0010] Preferably, the top of the base plate is symmetrically threaded with two reinforcing columns, and one end of the top of each reinforcing column is threaded to the top inner wall of the support frame.

[0011] Preferably, the two sets of anti-slip grooves are arranged symmetrically, and the cross-section of the anti-slip grooves is a number of triangles arranged at equal intervals.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the base plate is fixed above the soil layer, and a movable cone with a trapezoidal cross section is installed in several countersunk holes in the circular groove. This cone can transmit pressure and enhance the fixing strength. The hydraulic press drives the pressure plate to press the movable cone downwards and embed it into the soil layer, thereby achieving stable anchoring of the base plate and improving the overall fixing strength and reliability.

[0018] 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.

[0019] Please see Figure 1 An embodiment of this utility model provides a static pile driver for building engineering, including: a base plate 1.

[0020] Among them, such as Figures 1-3As shown, a support frame 2 is installed on the top of the base plate 1, and a hydraulic press 3 is installed on the top of the support frame 2. The piston rod of the hydraulic press 3 passes through the support frame 2 and is fixedly connected to a pressure plate 4. A circular groove 5 is provided on the top of the base plate 1, and a pile hole 6 is provided on the circular groove 5. During operation, the pile is placed in the pile hole 6 in the circular groove 5 on the top of the base plate 1, and the hydraulic press 3 drives the pressure plate 4 to press the pile into the soil layer.

[0021] Furthermore, four fixing cones 7 are symmetrically fixed to the top of the base plate 1, which can initially fix the base plate 1 to the top of the soil layer.

[0022] In this embodiment, as Figures 1-4 As shown, a number of countersunk holes 12 are distributed circumferentially on the circular groove 5. A movable cone 13 penetrates through the inside of the countersunk holes 12. The cross-section of the movable cone 13 is a continuous trapezoid from top to bottom. When the pile driver is installed, the base plate 1 is fixed above the soil layer. The movable cone 13 is installed in the number of countersunk holes 12 distributed circumferentially in the circular groove 5. The cross-section of the movable cone 13 is a continuous trapezoid from top to bottom, which can effectively transmit pressure and improve the fixing strength in the soil layer. When the hydraulic press 3 is in operation, it can drive the pressure plate 4 to move downward and enter the circular groove 5, apply pressure to the movable cone 13, and press the movable cone 13 into the ground. By using its structural shape to embed into the soil layer, the base plate 1 is firmly anchored.

[0023] Furthermore, two fixing plates 10 are symmetrically fixedly connected to the bottom of the base plate 1. The bottom of the fixing plate 10 is provided with two sets of anti-slip grooves 11. The two sets of anti-slip grooves 11 are symmetrically arranged, and the cross section of the anti-slip grooves 11 is a number of triangles arranged at equal intervals. When the base plate 1 is installed on the top of the soil layer, the fixing plate 10 can simultaneously adhere to the top of the soil layer, and the anti-slip grooves 11 are used to increase the grip of the fixing plate 10. The two sets of mutually symmetrical anti-slip grooves 11 can reduce the sliding of the base plate 1 and the fixing plate 10.

[0024] like Figure 1 As shown, the top of the support frame 2 is equipped with a hydraulic support 9, and the hydraulic press 3 is located inside the hydraulic support 9. The hydraulic support 9 can cover and protect the outside of the hydraulic press 3.

[0025] In addition, the top of the base plate 1 is symmetrically threaded with two reinforcing columns 8. One end of the top of the reinforcing column 8 is threaded to the top inner wall of the support frame 2. The reinforcing column 8 can further increase the fixing strength of the top support frame 2 of the base plate 1.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: During operation, the pile is placed in the pile hole 6 in the circular groove 5 at the top of the base plate 1, and the hydraulic press 3 drives the pressure plate 4 to press the pile into the soil layer.

[0027] When the pile driver is installed, the base plate 1 is fixed above the soil layer. Several countersunk holes 12 distributed circumferentially in the circular groove 5 are equipped with movable cones 13. The cross-section of the movable cone 13 is a continuous trapezoid from top to bottom, which can effectively transmit pressure and improve the fixing strength in the soil layer. When the hydraulic press 3 is in operation, it can drive the pressure plate 4 to move downward and enter the circular groove 5, apply pressure to the movable cone 13, and press the movable cone 13 into the ground. By embedding it into the soil layer using its structure, the base plate 1 is firmly anchored, thereby enhancing the overall fixing strength and reliability of the pile driver.

[0028] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
