Description

Technical Field

[0001] This invention relates to the field of spiral anchor technology, specifically to intelligent control type spiral steel pipe anchors or piles and their application methods. Background Technology

[0002] Helical anchor foundations are a type of foundation primarily suitable for areas with soft soil conditions such as river networks, swamps, and coastal mudflats. They can withstand both upward and downward pressure, relying mainly on their own weight, the weight of the soil, cohesion, and the bearing capacity of the foundation, with the helical anchor discs providing support. However, stress concentration can occur in individual helical anchor discs, causing the load to be concentrated there while other anchor discs receive insufficient load, potentially leading to structural failure. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent control type spiral steel pipe anchor or pile and its application method. By intelligently controlling the spiral anchor plate, the load is evenly distributed to each anchor plate, thus solving the problem of uneven load distribution.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Intelligent control type spiral steel pipe anchor or pile, including steel pipe for construction structure, spiral anchor plate, hydraulic winding and unwinding device, strain measurement unit and monitoring and control system;

[0006] The steel pipe used in the construction structure has slots on its wall for the spiral anchor disc placed inside to enter and exit.

[0007] The spiral anchor disc is a split component, and the inner diameter of the spiral anchor disc is connected to a hydraulic retraction device, which drives the spiral anchor disc to enter and exit the slot on the steel pipe.

[0008] The hydraulic retraction and deployment device is installed inside the steel pipe. The drive end of the hydraulic retraction and deployment device is connected to the spiral anchor plate, and the oil circuit connected to the top of the hydraulic retraction and deployment device extends out of the steel pipe.

[0009] The strain measurement unit is attached to the inner surface of the steel pipe and arranged circumferentially to monitor the deformation of the steel pipe.

[0010] The monitoring and control system includes a field monitoring device and a computer. The input end of the field monitoring device is electrically connected to the strain measurement unit, and the output end of the field monitoring device is electrically connected to the oil pump of the hydraulic retraction device. The system collects, processes, and stores the deformation data of the steel pipe and transmits it to the computer, as well as receives commands from the computer to adjust the degree of the spiral anchor disc entering and exiting the outer wall of the steel pipe.

[0011] Furthermore, the steel pipe can be replaced with a bearing body made of materials such as fiberglass, concrete, or cement, which has the same groove.

[0012] Furthermore, the spiral anchor disc adopts a multi-piece structure to achieve more precise control.

[0013] Furthermore, the hydraulic retraction device can be replaced by an electric motor.

[0014] Furthermore, the strain measurement unit has multiple components, and each strain measurement unit is attached to a different position on the steel pipe to monitor the deformation at different positions of the steel pipe.

[0015] Furthermore, the on-site monitoring device is electrically connected to the strain measurement unit via wires and communicates with a computer. The computer calculates the load shared by each spiral anchor plate based on the steel pipe deformation data sent by the on-site monitoring device, and sends a command to the on-site monitoring device to control the hydraulic retraction device, adjust the degree of each spiral anchor plate entering and leaving the outer wall of the steel pipe, and thus adjust the load-bearing ratio of each spiral anchor plate.

[0016] This invention discloses an application method for an intelligent control type spiral steel pipe anchor or pile, comprising the following steps:

[0017] (1) Detect underground obstacles in the application area, remove obstacles and backfill soil in a timely manner, level the site, and compact it in layers;

[0018] (2) Excavate the earthwork to the design elevation, measure and set out the location according to the requirements, and make permanent and temporary marks;

[0019] (3) Press the intelligent control type spiral steel pipe anchor or pile with the spiral anchor plate pre-retracted into the internal part at the designated construction location to ensure the anchor or pile position, verticality of the anchor or pile body and elevation;

[0020] (4) After the above steps are completed, release the spiral anchor plate inside the steel pipe. Subsequently, intelligent control of each spiral anchor plate is used to distribute the load evenly according to the load conditions.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] To address the issue of excessive load on a single spiral anchor disc while other anchor discs receive insufficient load, leading to structural damage, this invention proposes an intelligent control type spiral steel pipe anchor or pile and its application method (external hydraulic cylinder insertion). Through intelligent control of the spiral anchor discs, the load is evenly distributed to each disc, resolving the uneven load distribution, improving the structural stress state, enhancing reliability, and providing better load-bearing performance. This invention possesses strong practicality and broad application prospects. Attached Figure Description

[0031] like Figure 1-6 As shown, the intelligent control type spiral steel pipe 1 anchor or pile of the present invention includes a steel pipe 1 for construction structure, a spiral anchor plate 2, a hydraulic winding and unwinding device 4, a strain measurement unit 8 and a monitoring and control system.

[0032] The steel pipe 1 used for the construction structure has a slot 3 on its wall for the spiral anchor disc 2 placed inside to enter and exit.

[0033] The spiral anchor disc 2 is a split component. The inner diameter of the spiral anchor disc 2 is connected to the hydraulic retraction device 4, which drives the spiral anchor disc 2 to enter and exit the slot 3 on the steel pipe 1. The spiral anchor disc 2 adopts a multi-piece structure to achieve more precise control.

[0034] The hydraulic retraction device 4 is mounted on the fixed frame 7 inside the steel pipe 1. The drive end (hydraulic retraction rod 5) of the hydraulic retraction device 4 is connected to the spiral anchor plate 2. The oil circuit 6 connected to the top of the hydraulic retraction device 4 extends out of the steel pipe 1. The piston 5 of the hydraulic retraction device 4 moves back and forth, driving the hydraulic retraction rod 5 to extend and retract, thereby driving the spiral anchor plate 2 to enter and exit the slot 3 on the steel pipe 1.

[0035] The strain measurement unit 8 is attached and fixed to the inner surface of the steel pipe 1 and arranged circumferentially to monitor the deformation of the steel pipe 1. Preferably, there are multiple strain measurement units 8, and each strain measurement unit 8 is attached to a different position on the steel pipe 1 to monitor the deformation at different positions of the steel pipe 1.

[0036] The monitoring and control system includes a field monitoring device and a computer. The input end of the field monitoring device is electrically connected to the strain measurement unit 8, and the output end of the field monitoring device is electrically connected to the oil pump of the hydraulic expansion and contraction device 4 to collect, process, and store the deformation data of the steel pipe 1 and transmit it to the computer, as well as receive commands from the computer to regulate the degree to which the spiral anchor plate 2 enters and exits the outer wall of the steel pipe 1.

[0037] In this invention, the steel pipe 1 can be replaced by a support body made of materials such as fiberglass, concrete, or cement, which has the same groove 3. The hydraulic retraction device 4 can also be replaced by other driving devices such as an electric motor.

[0038] The on-site monitoring device is electrically connected to the strain measurement unit 8 via the wire 9 and communicates with the computer. Based on the deformation data of the steel pipe 1 sent by the on-site monitoring device, the computer calculates the load shared by each spiral anchor plate 2 and sends a command to the on-site monitoring device. The on-site monitoring device controls the hydraulic retraction device 4 to adjust the degree of each spiral anchor plate 2 entering and leaving the outer wall of the steel pipe 1, thereby adjusting the load-bearing ratio of each spiral anchor plate 2.

[0039] This invention discloses an application method for an intelligent control type spiral steel pipe anchor or pile, characterized by the following steps:

[0040] (1) Detect underground obstacles in the application area, remove obstacles and backfill soil in a timely manner, level the site, and compact it in layers;

[0042] (3) Press the intelligent control type spiral steel pipe 1 anchor or pile that has been pre-retracted into the spiral anchor plate 2 at the designated construction location to ensure the anchor or pile position, verticality of the anchor or pile body and elevation;

[0043] (4) After the above steps are completed, release the spiral anchor plate 2 inside the steel pipe 1. Subsequently, according to the load conditions, intelligent control is used to make the load evenly distributed among the spiral anchor plates 2.
