Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a cast-in-place pile structure with an overflow hole. Background Art

[0002] Cast-in-place piles are made by forming pile holes in the foundation soil through mechanical drilling, steel pipe squeezing or manual excavation, placing steel cages inside and pouring concrete. This construction method has the advantages of no vibration, no soil squeezing and strong bearing capacity. Cast-in-place piles are an effective underground foundation support structure and are widely used in various civil engineering projects, such as bridges, high-rise buildings, docks, etc.

[0003] The utility model patent with the authorization announcement number CN214695554U discloses a cast-in-place pile structure, which includes a mounting seat placed at the bottom of the pile hole and a steel cage at the top of the mounting seat, a connecting column is rotatably connected to the middle position of the top of the mounting seat, a connecting sleeve is arranged on the connecting column, a mounting groove is opened at the middle position of the top of the connecting sleeve and penetrates downward to the outside of the connecting sleeve, the connecting column passes through the mounting groove, the steel cage is provided with a fixing column for fixing the connecting sleeve, the connecting sleeve is provided with multiple groups of sliding holes at intervals above and below, each group of the sliding holes has two and is respectively located on both sides of the mounting groove, the sliding holes and the mounting groove are connected to each other, and the upper and lower adjacent groups of the sliding holes are perpendicular to each other, the connecting sleeve is provided with a positioning column sliding in the sliding hole, the connecting column is provided with a driving component for driving the positioning column to slide toward the wall of the pile hole, and the mounting seat is provided with a fixing piece for fixing the connecting column. When in use, the positioning column abuts against the wall of the pile hole to correct the position of the steel cage, so that the distance between the steel cage and the wall of the pile hole is in a relatively uniform state.

[0004] Although the cast-in-place pile structure is convenient for correcting the position of the steel cage, the device still has the following problems in actual use: when pouring concrete into the steel cage, during the construction of the cast-in-place pile, the concrete is pumped into the pile hole through the top of the drilled hole. Since bubbles and excess moisture will be generated in the concrete pouring process, if these air and moisture are not discharged in time, cavities or defects may be formed inside the pile body, affecting the quality and bearing capacity of the pile; at the same time, due to problems such as too fast concrete pouring speed or unreasonable pile body design, overpressure may be generated inside the pile body, thereby destroying the pile body structure. In view of this, we propose a cast-in-place pile structure with an overflow hole. Utility Model Content

[0030] In this embodiment, the cross-section of the annular rod 13 is annular, and the annular rod 13 is tightly welded to the fixing rings 12 on both sides. The annular design facilitates the connection and fixation of the annular rod 13 and the vertical rod 11, and the tight welding method ensures the stability of the annular rod 13.

[0031] In this embodiment, a plurality of vertical rods 11 are distributed in a ring shape with equal spacing, and the vertical rods 11 are tightly welded to the fixing ring 12. This design enhances the stability of the overall structure of the steel cage and ensures the bearing capacity of the steel cage.

[0032] In this embodiment, the overflow pipe 15 is arranged horizontally, and the overflow pipe 15 is a stainless steel product. The horizontally arranged overflow pipe can also effectively monitor and control the pouring speed and amount of concrete, thereby improving the construction efficiency and quality. The overflow pipe made of stainless steel not only ensures its strength and durability, but also maintains stable performance under different environmental conditions.

[0033] During specific use, the user uses a crane to lift the steel cage into a hole opened on the ground, and then the user inserts a conduit from the top opening of the steel cage, and injects the mixed concrete into the steel cage through the conduit. As the concrete accumulates in the hole, the moisture and bubbles in the concrete flow out from the inside of the steel cage through the overflow pipe 15 arranged horizontally. When the pouring is completed and the concrete is formed, the cast-in-place pile can be formed. Example

[0034] See also Figure 5-Figure 6In order to perform elevation positioning of the steel cage, this embodiment provides the following technical solutions on the basis of embodiment 1: an elevation positioning part 2 is provided at the top of the cast-in-place pile 1, and the elevation positioning part 2 includes a base 20, and a casing 21 is installed at the through hole at the center of the base 20, the casing 21 is tightly welded to the base 20, and the steel cage passes through the through hole and the casing 21; a plurality of fixed seats 22 are installed at the top circumferential side of the base 20, and a sliding cavity 221 is opened on one end surface of the fixed seat 22 close to the casing 21, and a sliding seat 23 is slidably installed in the sliding cavity 221, and a bearing rod 24 is installed at the end of the sliding seat 23, and the end of the bearing rod 24 passes through the casing 21 and is inserted into the steel cage, and the end of the bearing rod 24 is tightly pressed against the bottom of the corresponding fixing ring 12; a screw rod 25 is also rotatably installed in the sliding cavity 221, and the sliding seat 23 is threadedly connected to the screw rod 25.

[0035] In this embodiment, a hand wheel 26 is installed at the end of the screw rod 25, and the hand wheel 26 is fixedly connected to the end of the screw rod 25 by a bolt.

This guide design can ensure that the sliding seat 23 remains stable and steady when moving in the sliding cavity 221, reduces friction and shaking, and improves the reliability of the overall structure.

[0037] In this embodiment, the slide 23 and the bearing rod 24 are an integrally formed structure, and both the slide 23 and the bearing rod 24 are made of galvanized steel. The integrally formed structure enhances the connection strength between the components, improves the integrity and durability of the structure, and improves the elevation positioning effect of the bearing rod 24 on the steel cage.

[0038] It can be understood that the elevation positioning part 2 is used to perform elevation positioning on the steel cage, which plays a role of limiting the steel cage and preventing the steel cage from sinking in the pile hole, which is conducive to the construction of the cast-in-place pile 1 according to the standard.

[0039] During specific use, the user turns multiple hand wheels 26 on the side in turn, and the hand wheels 26 drive the screw rod 25 to rotate. As the screw rod 25 rotates, the slide 23 slides along the slide cavity 221, and the slide 23 drives the load-bearing rod 24 to move. When the load-bearing rod 24 is inserted between two adjacent ring bodies, the restrictions on the steel cage and the crane hook are released, and the multiple load-bearing rods 24 can carry the steel cage, and the steel cage cannot sink in the pile hole.
