Description

Technical Field

[0001] This utility model relates to the technical field of drilling construction auxiliary devices, specifically a corrugated pipe pile connection lateral support and limiting device. Background Technology

[0002] Drilled piles are widely used in construction projects in the Jiangsu and Zhejiang regions and are one of the most critical aspects of the construction process, having a profound impact on the entire project. It is not uncommon for projects to experience prolonged work stoppages after the completion of pile foundation work due to various difficulties; some projects require design changes to reduce the difficulty of resuming work, such as changing a two-story basement to a single-story one. Therefore, there is a strong practical need to complete the splicing of drilled piles quickly, safely, economically, and with high quality.

[0003] The conventional method uses corrugated pipes, positioning rings, and square timber. The positioning ring is composed of three 30mm Φ8 steel bars welded together and installed at one-third of the overall height of the corrugated pipe. The square timber is inserted into the groove of the positioning ring for lateral support. However, this simple structure is generally not reusable, and the support and limiting fixture must be remade each time according to the size of the corrugated pipe used. This is cumbersome, wasteful of materials, and the support effect is relatively poor.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

The splicing component includes two side seats, each seat having longitudinally staggered through holes. A support rod is inserted into the through holes at the same height of two adjacent seats, and the support rod has a sliding groove that slides through and is fitted with limiting components.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 The diagram illustrates a corrugated pipe joint lateral support and limiting device, wherein the corrugated pipe 1 joint is located within a borehole, and is further supported and limited by a support and limiting device 3. The support and limiting device 3 employs multiple circumferentially assembled splicing components, each using the same structure, and each splicing component has a hinged inclined rod 4 at its bottom for adjusting the angle of insertion into the outer borehole wall. Specifically, this example uses splicing components assembled sequentially on all four sides.

[0021] like Figure 2-3As shown: The splicing component includes two side seats 7. Each seat 7 has longitudinally staggered through holes 12. Support rods 5 are inserted into the through holes 12 at the same height on two adjacent seats 7. Support rods 5 have sliding grooves 11 and slide through to accommodate limiting members. Four limiting members abut against the four outer walls of the corrugated pipe 1. The position between the seat 7 and the support rods 5 is adjusted to accommodate different diameters of the corrugated pipe 1. Next, the inner side of the seat 7 connecting to the support rod 5 has a slot (enlarging the circular groove of the through hole 12). After adjusting the position, the pressing seat 10 is inserted into the slot. The pressing seat 10 is first fitted onto the support rod 5 and then inserted into the seat 7. Finally, a clamping head 6 is inserted into the outer end of the support rod 5.

[0022] The extrusion seat 10 has elongated slots on both sides that extend through one side, and the rear side of the extrusion seat 10 is wrapped with a padding layer (such as cotton pads or silicone pads), which makes the circumferential radial dimension larger. When it is inserted into the slot of the connector 7, the entire extrusion seat 10 contracts inward circumferentially, thereby securing the support rod 5 to a certain extent. It should be noted that the extrusion seat 10 is normally adapted to the size of the support rod 5.

[0023] The limiting component includes two spaced sleeves 8, one side of which forms a protrusion and is pivotally connected to an insert tube 9. The insert tube 9 is used to engage with the circumferential corrugations 2 of the bellows 1 for limiting, and is supported by the connector at the outer end and the inclined rod 4 at the bottom.

[0024] The outer periphery of the insert 9 needs to be wrapped with a friction pad of a certain thickness to increase the friction with the bellows 1. At the same time, due to the size of the concave part of the bellows 2 on the bellows 1, the friction pad can be squeezed and retracted to fit into the tube.

[0025] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
