Description

Technical Field

[0001] This utility model mainly relates to the field of hydraulic foundation pile structures, specifically a hydraulic engineering foundation pile. Background Technology

[0002] In the construction of water conservancy projects, it is necessary to first prepare the foundation, then drill pile holes in the foundation, and finally install foundation piles into the pile holes. Current foundation pile technology generally includes an outer cylinder and an inner cylinder. Reinforcing steel bars are then placed inside the inner cylinder and reinforced with concrete in the gaps, followed by the pouring of concrete. However, this method suffers from low construction efficiency and poor structural stability. Especially under complex geological conditions, it is prone to pile displacement or uneven settlement, and pile collapse can occur due to excessive pressure on the piles. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a hydraulic engineering foundation pile. Its main advantages are: by setting up a foundation pile pipe structure with multiple concrete filling chambers, and further setting up small concrete filling chambers connected to the concrete filling chambers around the foundation pile pipe, the center position of the foundation pile structure can be changed to the lower part by the small concrete filling chambers, improving the stability of the foundation pile; further, by setting up a lifting partition plate and lifting plate structure at the bottom of the foundation pile to separate the concrete filling chambers and the small concrete filling chambers; further, by setting a lifting column at the center of the lifting plate structure, and setting a support plate structure around the lifting column that can fit and support the foundation pile pipe; by raising the lifting partition plate, the concrete filling chambers are separated, and at the same time, the support plate structure moves towards the inner and outer periphery of the foundation pile pipe, providing support around the foundation pile pipe to prevent structural collapse; and further, by setting the lifting support structure as an adjustable structure, the support plate mechanism can be adjusted during subsequent use to cope with the gradually increasing external pressure on the foundation pile.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] Concrete injection baffles are fixedly installed around the inside of the foundation pile barrel. Concrete inlets are opened around the bottom of the foundation pile barrel at positions corresponding to the concrete injection baffles. A concrete box is fixedly installed on the outside of the foundation pile barrel at positions corresponding to the concrete inlets. A concrete baffle is fitted inside each concrete injection baffle and slidably connected thereto. A lifting base plate is fixedly installed at the bottom of each concrete baffle.

[0006] Furthermore, several supporting plate sliding columns are fixedly connected to the concrete injection partition on both sides of the foundation pile bucket at equal intervals. A supporting plate is provided between each concrete injection partition and is sleeved on the outer periphery of the supporting plate sliding column and slidably connected to it. Several supporting plate rotating supporting column seats are vertically fixed inside the supporting plate.

[0007] Furthermore, a lifting column is fixedly provided at the center of the lifting base plate, a lifting sleeve column is sleeved on the outer periphery of the lifting column, and a plurality of lifting rotating support column seats are fixedly provided at equal intervals around the outer periphery of the lifting sleeve column. A rotating shaft sleeve column is sleeved on the outer periphery of the lifting rotating support column seat and rotates in cooperation with it. One end of the rotating shaft sleeve column is sleeved on the outer periphery of the support plate rotating support column seat corresponding to its position and rotates in connection with it. A threaded column support ring is fixedly provided on the upper part of the lifting sleeve column, and a plurality of threaded columns are fixedly provided on the upper part of the threaded column support ring in a circular pattern.

[0008] Furthermore, the pile barrel is provided with a pile barrel cover on the upper part, and a lifting column hole is opened in the center of the pile barrel cover, which is slidably connected to the outer periphery of the lifting column. A threaded column hole is opened at the corresponding position of the pile barrel cover and the threaded column, and a nut is provided on the upper part of the threaded column hole, which is fitted to the outer periphery of the threaded column and threadedly engaged with it.

[0009] Compared with the existing technology, the beneficial effects of this utility model are:

[0010] 1. By setting up a pile pipe structure with multiple concrete filling chambers, and further setting up small concrete filling chambers connected to the concrete filling chambers around the pile pipe, the pile structure can change its center position to the lower part by the small concrete filling chambers, thereby improving the stability of the pile.

[0011] 2. A lifting partition plate and lifting plate structure are installed at the bottom of the foundation pile to separate the concrete filling chamber and the small concrete filling chamber. A lifting column is further installed at the center of the lifting plate structure, and a support plate structure that can fit and support the foundation pile tube is installed around the lifting column. The concrete filling chamber is separated by the lifting partition plate rising, and the support plate structure is moved to the outer periphery of the foundation pile tube to provide support around the foundation pile tube and prevent structural collapse. Furthermore, by setting the lifting support structure as an adjustable structure, the support plate mechanism can adjust the support force during subsequent use to cope with the gradually increasing external pressure of the foundation pile.

[0018] Example: A type of foundation pile for a water conservancy project

[0019] like Figure 1-4 As shown, a type of hydraulic engineering foundation pile has the following specific structure:

[0020] A hydraulic engineering foundation pile includes a foundation pile bucket 1. Concrete injection baffles 2 are fixedly installed around the inside of the foundation pile bucket 1, forming a concrete filling space through the baffles. Concrete openings 3 are opened around the bottom of the foundation pile bucket 1 at positions corresponding to the concrete injection baffles 2. A concrete box 4 is fixedly installed on the outside of the foundation pile bucket 1 at positions corresponding to the concrete openings 3. Concrete baffles 5 are fitted inside each of the concrete injection baffles 2 and slidably connected thereto. A lifting base plate 6 is fixedly installed at the bottom of each concrete baffle 5. The lifting base plate 6 is used to raise and lower the concrete baffles 5 to cover the concrete openings 3, thus separating the concrete box 4 from the inside of the foundation pile bucket 1.

[0021] The concrete injection partition 2 is fixedly connected to the foundation pile bucket 1 at equal intervals on both sides with a number of supporting plate sliding columns 7. A supporting plate 8 is provided between each concrete injection partition 2 and is sleeved on the outer periphery of the supporting plate sliding column 7 and slidably connected to it. A number of supporting plate rotating supporting column seats 9 are vertically fixed inside the supporting plate 8.

[0022] A lifting column 10 is fixedly provided at the center of the lifting base plate 6. A lifting sleeve column 11 is sleeved on the outer periphery of the lifting column 10. A plurality of lifting rotating support column seats 12 are fixedly provided at equal intervals around the outer periphery of the lifting sleeve column 11. A rotating shaft sleeve column 13 is sleeved on the outer periphery of the lifting rotating support column seat 12 and rotates with it. One end of the rotating shaft sleeve column 13 is sleeved on the outer periphery of the support plate rotating support column seat 9 corresponding to its position and rotates with it. The lifting sleeve column 11 rises, driving the lifting rotating support column seat 12 to rise and pushing the rotating shaft sleeve column 13. Furthermore, the rotating shaft sleeve column 13 pushes the support plate 8 to abut against the inside of the foundation pile barrel 1. A threaded column support ring 14 is fixedly provided on the upper part of the lifting sleeve column 11. A plurality of threaded columns 15 are fixedly provided on the upper part of the threaded column support ring 14.

[0023] The pile barrel 1 is provided with a pile barrel cover 16 on the upper part. The pile barrel cover 16 has a lifting column hole 17 in the center and is slidably connected to the outer periphery of the lifting column 10. The pile barrel cover 16 has a threaded column hole 18 at the corresponding position of the threaded column 15. The threaded column hole 18 is provided with a nut sleeve 19 on the upper part and is threadedly engaged with the outer periphery of the threaded column 15. By rotating the nut sleeve 19, the threaded column 15 is driven to rise, which in turn drives the lifting column 11 to rise.

[0024] This solution also includes a controller, the location of which is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication devices, lights, speakers, and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a lithium battery. When a display screen is provided, a graphics card is also included. For the operating principle of the controller, please refer to "Principles of Automatic Control," "Microcontroller Principles and Application Simulation Cases," and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are knowledge well known to those skilled in the art and will not be described in detail here.

[0025] Working principle:

[0026] In use, the foundation pile bucket 1 is first placed inside the pile hole, at which point the lifting base plate 6 is separated from the foundation pile bucket 1, and the concrete baffle 5 is not obstructing the concrete inlet 3. Further concrete is poured into the concrete injection partition 2, where a reinforcing steel structure is placed, and concrete is poured. During the concrete pouring process, a portion of the concrete enters the concrete box 4 through the concrete inlet 3. After pouring is completed, the foundation pile bucket 1 is pushed down further, causing the concrete baffle 5 and the lifting base plate 6 to rise relative to the foundation pile bucket 1, thereby allowing the concrete baffle 5 to obstruct the concrete inlet 3. The concrete inlet 3 separates the concrete box 4 from the interior of the pile foundation bucket 1. The concrete inside the concrete box 4 provides counterweight to the pile foundation bucket 1, improving its stability. The lifting base plate 6 rises, simultaneously pushing the lifting sleeve column 11 to rise, which in turn pushes the support plate 8 to support the interior of the pile foundation bucket 1, providing it with support force. After pouring, the pile foundation bucket cover 16 is installed on the top of the pile foundation bucket 1 to protect its internal structure. Furthermore, the nut sleeve 19 and the threaded column 15 are threaded together, allowing the lifting sleeve column 11 to rise further, strengthening the support force of the support plate 8 on the interior of the pile foundation bucket 1.
