[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a leak-proof casing for bored piles penetrating island walls. Background Technology

[0002] Drilled piles are piles made by forming pile holes in the foundation soil through mechanical drilling, steel pipe extrusion, or manual excavation on the engineering site, and then placing a steel cage inside and pouring concrete. According to different hole-forming methods, drilled piles can be divided into several categories such as driven cast-in-place piles, drilled cast-in-place piles, and excavated cast-in-place piles.

[0003] Piled piles through island walls refer to drilling through retaining walls or revetment structures on islands. This involves underwater or complex geological conditions. Existing drilled piles may experience grout leakage during construction. The rotation of the drill bit during drilling can cause the casing to vibrate and sink, resulting in grout flowing out of the casing, which affects the quality and stability of the hole and may lead to hole collapse. Summary of the Invention

[0004] The purpose of this utility model is to provide a leak-proof casing for bored piles penetrating island walls, in order to solve the technical problem that the casing sinks due to vibration during drilling, causing mud to flow out of the casing and affecting the quality of the hole. The purpose is to fix the casing and prevent it from sinking during drilling, thereby avoiding mud flow.

[0005] To solve the above-mentioned technical problems, this utility model provides a leak-proof casing for bored piles penetrating island walls, comprising: an outer cylinder, the outer wall of which is provided with locking teeth; and a fixing component at the top of the outer cylinder, the fixing component comprising a fixing ring, a connecting plate and a fixing cone;

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example:

[0036] As shown in Figures 1 to 6, a leak-proof casing for a borehole pile penetrating an island wall includes an outer cylinder 1, an inner cylinder 2, and a fixing component 3. The inner cylinder 2 is detachably installed inside the outer cylinder 1, and the outer wall of the inner cylinder 2 is slidably connected to the inner wall of the outer cylinder 1. The fixing component 3 is installed at the top of the outer cylinder 1.

[0037] The outer wall of the outer cylinder 1 is provided with locking teeth 13. After the outer cylinder 1 is placed in the hole, the locking teeth 13 abut against the inner wall of the hole, increasing the friction between the outer cylinder 1 and the hole, making its fixing effect better and preventing the outer cylinder 1 from sliding down. The inner wall of the outer cylinder 1 is provided with multiple slots 11 vertically, the slots 11 penetrate through the top of the outer cylinder 1, and the top of the outer cylinder 1 is provided with multiple insertion holes 12.

[0038] As shown in Figure 6, the fixing component 3 includes a fixing ring 31, a connecting plate 32, and a fixing cone 33. The fixing ring 31 surrounds the top outer wall of the outer cylinder 1, and the bottom end of the fixing ring 31 is provided with an insert ring 34, which is located on the outside of the outer cylinder 1. The outer cylinder 1 is placed in the hole, the fixing ring 31 is placed on the ground, and the insert ring 34 is inserted into the ground to initially fix the outer cylinder 1 and prevent the outer cylinder 1 from sliding and affecting subsequent operations.

[0039] The connecting plate 32 is connected to the side wall of the fixing ring 31, and the fixing cone 33 is detachably connected to the connecting plate 32. The connecting plate 32 and the fixing ring 31 are set horizontally, and the fixing cone 33 penetrates the top and bottom of the connecting plate 32 vertically. The fixing cone 33 penetrates the connecting plate 32 and is inserted into the ground to fix the outer cylinder 1 and prevent it from slipping and causing the mud to flow out.

[0040] In this embodiment, the fixed cone 33 includes a rod 331 and a cone 332. The top end of the cone 332 is connected to the bottom end of the rod 331. The rod 331 is located inside the connecting plate 32, and the cone 332 is located below the connecting plate 32 and inserted into the ground. A handle 334 is provided at the top end of the rod 331, and the height of the rod 331 is greater than the height of the connecting plate 32. A baffle 333 is provided between the rod 331 and the cone 332, and between the rod 331 and the handle 334. The baffle 333 is horizontally located on the outside of the connecting plate 32. The fixed cone 33 slides up and down inside the connecting plate 32 through the baffle 333 to prevent the fixed cone 33 from being lost during the fixing process. The fixed cone 33 and the connecting plate 32 can be connected by threads or by insertion. The handle 334 facilitates the installation and removal of the fixed cone 33, thereby improving the efficiency of fixing the outer cylinder 1.

[0041] In this embodiment, multiple insertion rods 211 are vertically arranged on the outer wall of the inner cylinder 2. The multiple insertion rods 211 are respectively matched with multiple slots 11. The inner cylinder 2 is installed in the outer cylinder 1 by inserting the insertion rods 211 into the slots 11. A waterproof ring 21 is provided at the top of the inner cylinder 2. The inner diameter of the waterproof ring 21 is smaller than the inner diameter of the inner cylinder 2, and the outer diameter of the waterproof ring 21 is larger than the outer diameter of the inner cylinder 2. The waterproof ring 21 covers the top of the inner cylinder 2 to prevent the mud in the inner cylinder 2 from flowing out from the top. Multiple insertion blocks 212 are provided at the bottom of the waterproof ring 21. The insertion blocks 212 are located on the outside of the inner cylinder 2. The multiple insertion blocks 212 are respectively matched with multiple insertion holes 12. The insertion blocks 212 are inserted into the insertion holes 12 to further fix the inner cylinder 2 and prevent the inner cylinder 2 from sliding with the outer cylinder 1 during drilling operations, which would cause the mud to flow out. A waterproof layer 22 is attached to the inner wall of the inner cylinder 2 to prevent the mud from flowing out from the gap between the inner cylinder 2 and the outer cylinder 1.

[0042] In summary, after the hole is drilled, the inner cylinder 2 is inserted into the outer cylinder 1 to connect the inner cylinder 2 and the outer cylinder 1. Then, the outer cylinder 1 and the inner cylinder 2 are placed into the hole. During the lowering process, the insertion ring 34 is inserted into the ground, and the fixing cone 33 is inserted into the ground through threaded connection or pressing, thereby fixing the outer cylinder 1 and the inner cylinder 2. The retaining teeth 13 on the outer wall of the outer cylinder 1 abut against the inner wall of the hole to prevent the casing from sliding down. The waterproof ring 21 and the waterproof layer 22 on the inner cylinder 2 prevent mud from flowing from the inner cylinder 2 into the outer cylinder 1, thereby compromising the stability of the hole. After the drilling operation is completed, the fixing cone 33 is pulled out by the lever 334 to remove the outer cylinder 1 and the inner cylinder 2.
