Description

Technical Field

[0001] The invention belongs to the technical field of foundation construction technology of building construction projects, and specifically relates to a device for improving full-rotation and full-casing machinery in limestone areas. Background Art

[0002] With the advancement of urbanization, current construction projects face the challenges of various complex geological conditions. In karst landforms (limestone areas), long-term groundwater erosion and the unique geological structure often form caves, soil holes, and fissures. This phenomenon is particularly prevalent in karst areas, resulting in an extremely high frequency of soil holes in projects (over 60%).

[0003] Traditional solutions to these problems include grouting or pile reinforcement. However, facing complex situations like high hole-visibility rates, engineers are now adapting their construction strategies, often employing fully-rotating, fully-cased pile foundations or combining raft foundations with anti-floating anchors.

[0004] However, the following problems still exist:

[0005] 1. Although traditional methods can ensure construction quality, the complexity of underground conditions makes it difficult to control the amount of work, which often leads to later costs significantly exceeding the initial budget target. If prefabricated pipe piles are used, complex geology and the proneness to encountering inclined rock at the bottom of the piles will lead to insufficient bearing capacity.

[0006] 2. Although the current improvement strategy increases costs, it ensures quality while keeping the project volume within the expected range. However, when encountering extremely complex geological conditions, especially in areas near water sources where groundwater is abundant and many soil holes appear, the design of a raft foundation + anti-floating anchor rods often cannot meet the bearing capacity requirements. This requires us to use pile foundation construction. Due to the high hole rate, the bearing layer at the bottom of the pile often has invisible cracks, large fluctuations in the bearing layer, or the bearing layer strength does not meet the design requirements. The stability of the bearing layer at the bottom of the pile cannot be guaranteed, which does not comply with relevant national standards. As a result, the quality of the piles is far below expectations.

[0007] To this end, the present invention provides a device for improving full-rotation and full-casing machinery in limestone areas. Summary of the Invention

When working, the auxiliary drill is used to drill a hole, and the device is fixed inside the drill hole after drilling. The device can effectively solve the problem of insufficient stability of the pile foundation bearing layer and inability to provide sufficient bearing capacity before the full-rotation full-casing mechanical pouring of concrete. , thereby ensuring the safety of the construction process and the quality of the project. When using the device, first use the full-rotation full-casing machine to drill a hole from the ground to the designed pile bottom elevation, then lower the device body 1 to the pile bottom through the drilling and fix it, and the device is used to reinforce the pile foundation. Then, lower the double-tube rotary jet pile driver along the device to the designed pile bottom elevation, and fix the device. Then, start rotary drilling to five meters below the pile bottom elevation, and spray while digging. When the device shows that the treatment within a five-meter range has been completed, remove the device for subsequent concrete construction.

[0036] The monitoring is carried out by an infrared ray meter 6 fixedly installed on the inner wall of the device body 1, and through pre-set parameters, the instrument can detect the stability of the slurry, thereby indicating whether the device can be dismantled. The steel column 3 is designed to ensure the verticality of the rotary drilling machine, and the sinking operation of the device is realized through the steel column 3. The steel plate 2 is fixed to the device body 1 through the clamping component 5, which helps to ensure stability during construction and prevent excessive upwelling of bottom sediment, thereby avoiding excessive sediment at the bottom of the pile, affecting the quality of the project. The steel plate 2 is designed to have a high slope in the middle and low slopes around to ensure that excess slurry can be discharged after the construction is completed, further ensuring the quality of the pile body. The one-way control component 8 makes the leakage net 9 one-way in and out, which can effectively prevent sediment from entering the bottom of the pile and allow excess slurry to enter the interior of the device.
