Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to a strong fixing structure of a pile foundation. Background Art

[0002] In civil engineering projects, pile driving and pouring is usually carried out at the construction site by a pile driver. When the soil is relatively loose, a casing needs to be inserted into the soil, and concrete is poured in the casing, and a stable pile foundation is formed through the solidification of the concrete.

[0003] Upon checking, the public announcement number: CN220538693U discloses a pile foundation fixing structure, which can realize pile foundations of different depths by pouring concrete through a detachable casing; however, the above technical solution arranges a connecting rod on the outside of the casing, and the contact area between the connecting rod and the loose soil is small, which causes the casing to tilt when placed downward, and the mutual connection between the casings requires multiple connecting parts, which is cumbersome and inefficient. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a strong fixing structure for a pile foundation, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a strong fixing structure of a pile foundation, including a casing, the inner wall of the casing is fixedly connected with reinforcing ribs, the reinforcing ribs open a through hole inside, the lower end of the casing is fixedly connected with a connecting rod, the connecting rod is arranged on both sides of the through hole, and the upper end of the casing is opened with a connecting hole matching the connecting rod.

[0006] Furthermore, a guard ring is fixedly connected to the upper edge of the protective tube, a guard groove is opened at the lower edge of the protective tube, the guard ring and the guard groove are matched, and the upper and lower connecting end edges of the protective tube are flush.

[0007] Furthermore, a slot is provided at the upper end of the through hole, a plug is fixedly connected to the lower end of the through hole, and the slot and the plug are matched and plugged together.

[0011] Compared with the above-mentioned background technology, the strong fixing structure of the pile foundation provided by the present application includes a pile foundation fixing structure with very mature technology today, and a core component with reinforcing ribs and connecting rods. Its principle relies on that the reinforcing ribs improve the overall hardness and stability of the casing, and the upper and lower ends of the casing are connected to each other through connecting rods and connecting holes, which reduces the number of connecting parts connecting the casings to each other and facilitates operation.

[0012] The utility model provides a strong fixing structure for pile foundation. Compared with the prior art, it has the following beneficial effects:

[0013] The strong fixing structure of the pile foundation can form a stable concrete pile foundation by arranging reinforcing ribs and connecting rods, and the outer wall of the casing and the inner wall of the pile pit are squeezed against each other.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a strong fixing structure for pile foundation, including a casing 1, the inner wall of the casing 1 is fixedly connected with a reinforcing rib 2, the reinforcing rib 2 makes a through hole 3 opened inside, the lower end of the casing 1 is fixedly connected with a connecting rod 6, the connecting rod 6 is arranged on both sides of the through hole 3, and the upper end of the casing 1 is provided with a connecting hole 8 matching the connecting rod 6; the casings 1 are stacked and connected with each other, the reinforcing rib 2 on the inner wall of the casing 1 can increase the overall firmness of the casing 1, and the through hole 3 is opened inside the reinforcing rib 2, the connecting rod 6 at the lower end of the casing 1 is inserted into the pile pit, and a stable plug-in effect is achieved through multiple connecting rods 6. When the upper and lower ends of the casing 1 are connected to each other, the connecting rod 6 is matched with the connecting hole 8 for plugging and connecting to each other. First, the casing 1 is vertically placed into the pile pit, the casing 1 is pressed to make the connecting rod 6 plugged into the pile pit, and then the casing 1 is successively When the piles are stacked together and connected with each other through the connecting rod 6 and the connecting hole 8, concrete is poured into the casing 1. After the concrete solidifies, grouting can be performed through the through hole 3. The casing 1 is pulled out upward while grouting, and the internal space is vacated when the casing 1 is pulled out upward, so that the concrete fills the interior of the pile foundation. The overall firmness of the casing 1 is increased by the reinforcing ribs 2. The connecting rod 6 can not only match the connection, but also can be plugged and fixed with the inside of the pile pit. Multiple connecting rods 6 can be stably plugged to improve stability and firmness. The reinforcing ribs 2 are arranged inside the casing 1, and the outer side of the casing 1 is tightly against the loose soil, so that stable support and solidification can be provided to form a better concrete pile foundation without soil residue mixing. The interconnection between the integrally formed connecting rod 6 and the casing 1 can better improve the efficiency of installation and disassembly.

[0021] like Figure 3 and Figure 4 As shown, a guard ring 9 is fixedly connected to the upper edge of the casing 1, and a guard groove 10 is opened at the lower edge of the casing 1. The guard ring 9 and the guard groove 10 are matched, and the upper and lower connecting end edges of the casing 1 are flush. The guard ring 9 at the upper edge of the casing 1 and the guard groove 10 at the lower edge of the casing 1 are plugged and matched with each other. When concrete is poured into the casing 1, the staggered connection between the guard ring 9 and the guard groove 10 can prevent the concrete moisture from overflowing, thereby achieving a better concrete solidification effect.

[0023] like Figure 4As shown, the lower end of the connecting rod 6 is provided with an inclined insertion surface 7, which is arranged around the connecting rod 6, so that the lower end of the connecting rod 6 is conical. The inclined insertion surface 7 is opened at the lower end of the connecting rod 6, and the lower end of the connecting rod 6 is conical through the surrounding opening, which makes it easier to insert the casing 1 into the pile foundation.

[0024] like Figure 3 As shown, the side wall of the guard ring 9 is provided with a penetrating lifting hole 11, and the number of the lifting holes 11 is set in multiples and the spacing is equal. The lifting holes 11 are set on the side wall of the guard ring 9. When the casing 1 is taken out from the pile foundation, the casing 1 is pulled out upward through the lifting holes 11. The number of the retaining ring 9 is set in multiples and the spacing is equal so that it can be lifted upward smoothly.
