Description

Steel pile casing for filling pile

Technical Field

The utility model relates to the technical field of building pile driving construction, in particular to a steel pile casing of a cast-in-place pile.

Background

In cast-in-situ bored piles, steel casings are often buried to locate the pile site to be drilled. The pile casing is made of steel, the wall thickness is 10mm, when the pile casing is positioned, the pile position center is used as the center of a circle, the position of the pile casing is determined on the soil according to the radius of the pile casing, and after the pile casing is positioned, the pile casing is buried into the soil by applying pressure for about 50cm. The soil body at the hole site can be dug out to a part firstly, and then the pile casing is placed to be buried underground. During the embedding process, the protection cylinder is checked to be vertical, and if the deflection is found, the protection cylinder is corrected in time. After the land pile casing is buried in place, the outside of the pile casing is backfilled and compacted by clay to prevent water leakage around the pile casing, the backfilling thickness is about 40-45cm, the top height is 0.4-0.6m higher than the ground (water surface), and the deviation of the cylinder position from the hole center is not more than 50m.

The Chinese patent with the application number of 202111505272.3 discloses a steel pile casing of a cast-in-place pile, which comprises two or more cylindrical steel cylinders, wherein the two or more steel cylinders are arranged at intervals up and down, a telescopic net is detachably connected between any two adjacent steel cylinders, the telescopic net encloses a cylindrical structure matched with the steel cylinders, and a plurality of hoisting ropes are connected to the uppermost steel cylinder; the telescopic net is used for blocking karst cave. The steel pile casing of the filling pile is formed by connecting the steel cylinder and the telescopic net, the telescopic net is used for plugging a karst cave in the filling pile, and the telescopic net deforms and protrudes into the karst cave when being subjected to the outward extrusion force of concrete, so that the combination of a pile body and a peripheral soil body is enhanced, and the bearing capacity and the stability of the pile body are improved; compared with the traditional steel pile casing, the cast-in-place pile steel pile casing shortens the length of the casing body, reduces the use of materials, is convenient to manufacture, transport and install, and can reduce the construction cost and improve the construction efficiency.
