Description

Technical Field

[0001] This utility model relates to the technical field of compaction pile construction devices, and in particular to a compaction pile construction device for collapsible loess soil. Background Technology

[0002] Collapsible loess is prone to structural damage and subsidence when exposed to water. Lime-soil compaction piles are often used for treating poor foundation conditions. The specific construction method involves drilling holes in the ground beforehand and preparing the fill material. After drilling is completed, the fill material is inserted into the holes. The fill material is added to each hole in multiple stages, and compaction is required after each addition.

[0003] The equipment used for compaction is a clamp-and-hammer device. The clamp-and-hammer at one end is lifted and, through free fall or pushing, hammers into the borehole for compaction. The compaction of the pile body is determined by manually observing the number of compactions and the height of the clamp-and-hammer's fall. This process is prone to errors, resulting in insufficient compaction. If subsequent pile foundation testing reveals substandard compaction, rework is required, which is detrimental to shortening the construction period and saving construction costs. Summary of the Invention

[0004] To address the aforementioned problems, this utility model discloses a construction device for compaction piles in collapsible loess soil, comprising a clamping hammer. The upper end of the clamping hammer has an installation groove, inside which a sensor unit is installed. The sensor unit contains a displacement sensor and an inertial sensor, and a magnet is fixedly connected to the back of the sensor unit. During operation, the displacement and inertial sensors acquire the hammer's motion state and transmit it to a host computer. The computer calculates whether the compaction of the soil is adequate. If not, the computer adjusts the height and frequency of the hammer's free fall and the thickness of the fill material to determine the parameters for the next compaction operation. This method provides a clear visual indication of whether the compaction meets construction requirements, which helps shorten the construction period and ensure construction quality.

[0005] A satellite positioning module is fixedly connected to the upper end of the clamping hammer. The use of BeiDou positioning ensures the accurate location of each compaction point.

[0006] Preferably, a protective cover is fixedly connected to the upper end of the clamping hammer, and the sensor unit and satellite positioning module are both located below the protective cover. That is, the protective cover protects the sensor unit and satellite positioning module below it, and the protective cover is made of plastic to reduce interference with the satellite positioning module.

[0007] Preferably, a handle is fixedly connected to the front of the sensor unit. This facilitates pulling the sensor unit to detach it from the clamping hammer.

[0008] Preferably, the construction device further includes a host computer, and the sensor unit and satellite positioning module are electrically connected by a communication cable, the other end of which is electrically connected to the host computer. The host computer receives the motion parameters of the clamping hammer and displays the data on a preset display screen.

[0009] Preferably, the construction device further includes a host computer, and the sensor unit, satellite positioning module, and host computer are all electrically connected to a wireless communication module. Through wireless communication, construction status can be acquired over a long distance.

[0010] Preferably, the wireless communication module is equipped with a battery and an antenna. The battery powers the sensor unit and the satellite positioning module, while the antenna is the component for wireless communication.

[0011] Preferably, a connecting protrusion is provided at the middle of the upper end of the clamping hammer, a connecting rod is provided above the connecting protrusion, a connecting plate is fixedly connected to the lower end of the connecting rod, and several bolts are inserted inside the connecting plate, with the bolts threadedly connected to the connecting protrusion. The connecting rod is the connecting component of the clamping hammer, and a sling is provided at the upper end of the connecting rod, with the other end of the sling attached to the winch.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. After the sensor unit and satellite positioning module are set in the clamping hammer, the pile body data can be collected in real time and accurately. This provides key basis for dynamically adjusting construction parameters such as hammering force, frequency, and filling amount, ensuring stable and accurate pile formation, improving the quality of pile foundation construction, avoiding subsequent rework, and shortening the construction period.

[0014] 2. The sensor unit, satellite positioning module, and host computer can use wired or wireless communication to meet the layout needs during construction. Attached Figure Description

[0023] like Figures 1 to 5 As shown, a construction device for compaction piles in collapsible loess includes a clamping hammer 1, which is lifted and then released for compaction. The upper end of the clamping hammer 1 is provided with an installation groove 6, and a connecting protrusion 5 is provided in the middle of the upper end of the clamping hammer 1. A connecting rod 4 is provided above the connecting protrusion 5, and a connecting plate 3 is fixedly connected to the lower end of the connecting rod 4. Several bolts are inserted inside the connecting plate 3, and the bolts are threadedly connected to the connecting protrusion 5. A portion of the installation groove 6 extends into the interior of the connecting protrusion.

[0024] The mounting slot 6 houses a sensor unit 7, which contains a displacement sensor and an inertial sensor. These sensors acquire data on the changes in the speed and height of the clamping hammer during operation, allowing for the calculation of the compaction depth and force. This quantification provides a clear picture of whether the current compaction work meets construction requirements, facilitating shorter construction periods and ensuring consistency across the entire construction area. A magnet is fixedly connected to the back of the sensor unit 7, meaning it is magnetically attached to the clamping hammer 1. After being placed in the mounting slot 6, the sensor unit 7 is magnetically attracted, causing it to adhere to the connecting protrusion. The structure of the mounting slot 6 is detailed below. Figure 2 As shown, the vertical movement of sensor unit 7 is restricted.

[0025] A satellite positioning module 9 is fixedly connected to the upper end of the clamping hammer 1. During the compaction operation, the satellite positioning module 9 ensures that the clamping hammer 1 meets the landing point requirements of the construction design.

[0026] The upper end of the clamping hammer 1 is fixedly connected to a protective cover 2. The protective cover 2 has a ring structure and a countersunk hole at its upper end. It is also fixed to the connecting protrusion by bolts. The sensor unit 7 and the satellite positioning module 9 are both located below the protective cover 2. The protective cover 2 is used to protect the sensor unit 7 and the satellite positioning module 9. At the same time, the protective cover 2 is made of plastic to reduce signal shielding and ensure the accurate position of the satellite positioning module 9.

[0027] A handle 8 is fixedly connected to the front of the sensor unit 7. The handle 8 is a round rod that has been bent twice. When removing the sensor unit 7, grasp the handle 8 and pull the sensor unit 7 radially. Once the upper end of the sensor unit 7 is no longer obstructed, it can be taken out upwards.

[0028] The construction device also includes a host computer 11, which is equipped with a display screen, a computing unit, etc. The sensor unit 7 and the satellite positioning module 9 are electrically connected by a communication cable 10, and the other end of the communication cable 10 is electrically connected to the host computer 11. Through the wired connection, the data transmitted by the sensor unit 7 and the satellite positioning module 9 is processed and displayed to achieve visualization.

[0029] Furthermore, the difference from the above is:

[0030] The construction device also includes a host computer 11, and the sensor unit 7, satellite positioning module 9, and host computer 11 are all electrically connected to a wireless communication module 13. The use of the wireless communication module 13 enables long-distance acquisition of construction information.

[0031] The wireless communication module 13 is equipped with a battery 12 and an antenna 14. The battery 12 provides power to the sensor unit 7 and the satellite positioning module 9, while the antenna 14 is an essential component for wireless communication.
