Description

Technical Field

[0001] The utility model relates to a steel casing rapid pile sinking device. Background Art

[0002] Steel casing is an industrial product used to protect bored piles, commonly used in manual bored pile construction. Because unstable soil conditions make the construction of reinforced concrete retaining walls challenging, steel retaining walls are used to protect the bored piles, prevent collapse, and ensure construction progress and safety. Steel casing is a circular barrel-shaped structure made of sheet metal, hollow at both ends, tailored to the size of the bored pile.

[0003] Steel casings are primarily used to protect bridge piers and other critical areas. They resist erosion from natural factors such as water flow, sediment, and floating debris, reducing the risk of structural damage. Furthermore, they can withstand impacts from external objects such as ships and drifting objects, providing additional safety. In extreme weather conditions such as floods and high winds, steel casings can effectively reduce stress on the structure and mitigate safety risks.

[0004] The steel casing is made of steel, usually with a wall thickness of 10mm. It is cylindrical in shape and is made of iron sheets according to the size of the pile. It ensures that there are no protrusions inside the casing, and it is resistant to tension, pressure, and water leakage.

[0005] When installing steel casing under complex geological conditions with riprap layers, it is difficult to punch and drill holes in the complex geological conditions of the riprap layers, which affects the installation of the steel casing. Therefore, a steel casing rapid pile sinking device is proposed to address the above problems. Utility Model Content

[0006] The utility model aims to overcome the existing defects and provide a steel casing rapid pile sinking device, thereby improving the efficiency of punching and hole guiding construction.

[0007] The technical solution to achieve the above object is: a steel casing rapid pile sinking device, comprising a support tube, a conical drill bit, a plurality of crushing blocks, a drill rod and six steel sections;

[0008] The support tube is connected above the conical drill bit, the center above the conical drill bit is connected to the drill rod, the outer wall of the drill rod is connected to six pieces of steel sections at equal distances, the other end of the steel sections is connected to the inner wall of the support tube, the gap between the inner wall of the support tube and the steel sections is filled with weight blocks, and multiple crushing blocks are evenly distributed and connected to the outer wall of the conical drill bit.

[0009] Preferably, the support tube is formed by welding double-layer thickened steel plates.

[0010] Preferably, the weight block can be concrete or stone.

[0011] Preferably, the support tube and the conical drill bit are connected by welding.

[0012] Preferably, the steel section is connected to the inner wall of the support tube by welding.

[0013] The beneficial effects of this utility model are as follows: the steel casing rapid pile sinking device can be used for multiple purposes, including punching and drilling, as well as for steel casing burial construction, thereby improving construction efficiency. Simultaneously, the weight of the filler and the drill bit can be utilized to quickly penetrate complex geological conditions such as gravel layers, greatly improving construction efficiency. The filler can be sourced locally and reused, reducing transportation and turnover costs. The drill rod length can be adjusted to meet the requirements of casing burial according to different pile types and hole depth requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a steel casing rapid pile sinking device includes a support tube 1, a conical drill bit 2, multiple crushing blocks 3, a drill rod 4 and six steel sections 5; the support tube 1 is made of double-layer thickened steel plates welded together. The support tube 1 is connected above the conical drill bit 2, and the support tube 1 and the conical drill bit 2 are connected by welding. The drill rod 4 is connected to the center above the conical drill bit 2, and six steel sections 5 are connected to the outer wall of the drill rod 4 at equal distances. The other end of the steel section 5 is connected to the inner wall of the support tube 1, and the steel section 5 and the inner wall of the support tube 1 are connected by welding. The gap between the inner wall of the support tube 1 and the steel section 5 is filled with a weight block 6, which can be concrete or stone. Multiple crushing blocks 3 are evenly distributed and connected to the outer wall of the conical drill bit 2.

[0019] Specifically, the support tube 1 is welded and assembled by double-layer thickened steel plates, and its interior is filled with concrete or stones. The conical drill bit 2 is welded to the support tube 1. At the same time, a drill rod 4 is used to connect the top center of the conical drill bit 2 and extend it to the top of the device. Then, six steel sections 5 are evenly distributed and welded to the inner wall of the support tube 1, thereby achieving the lifting force. The double-layer support tube 1 and the conical drill bit 2 are squeezed downward to penetrate the gravel layer under the action of gravity, thereby achieving the purpose of drilling. The steel casing can also be placed on the outer layer of this device. After the casing is in place and the top steel section connection is released, the drill bit and the support tube can be lifted separately, thereby achieving the purpose of burying the casing.

[0020] This steel casing rapid pile sinking device has multiple uses, including punching and drilling, as well as for steel casing burial construction, improving construction efficiency. It also leverages the weight of the filler and drill bit to quickly penetrate complex geology, such as gravel layers, significantly improving construction efficiency. The filler can be sourced locally and reused, reducing transportation costs. The drill rod length can be adjusted to meet the requirements of casing burial, depending on the pile type and hole depth.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
