Easy-to-use hand-dug pile retaining formwork

Abstract

The invention discloses a hand-excavated pile retaining formwork which is convenient to use. The formwork body is assembled from at least two curved formworks, one side of the two curved formworks is rotatably connected, and the other side is overlapped; There is a bracket in the body; the bracket includes an upper support frame and a lower support frame arranged at intervals in the middle of the formwork body, and the upper support frame includes a first connecting cylinder and a plurality of circumferentially arranged on the first connecting cylinder The upper support cross bar, the lower support frame includes a second connecting cylinder and a plurality of lower support cross bars circumferentially arranged on the second connecting cylinder, one end of the upper support cross bar and the lower support cross bar are respectively fixed at the second The outer wall of the first connecting cylinder and the second connecting cylinder, and the other end is rotatably installed on the inner wall of the curved formwork; a lifting rod that can move up and down and be positioned is arranged in the first connecting cylinder and the second connecting cylinder, and the lower end of the lifting rod The circumferential direction is provided with a plurality of adjusting horizontal bars whose left and right ends are rotatably connected with the lifting rod and the inner wall of the curved formwork respectively.

Description

technical field [0001] The invention relates to an artificial hole-digging pile, in particular to a hand-digging pile wall protection formwork which is convenient to use. Background technique [0002] Manual digging piles are reinforced concrete piles that are excavated by manpower and poured on site. Because of their simple construction equipment, small construction site occupation, no impact on surrounding buildings, reliable pile body quality, and low cost, they are popular at home and abroad. be more widely used. The common construction method is to manually excavate the soil (rock) to form a round hole, and every 1 meter or so to dig a formwork and pour a circle of concrete retaining wall, so as to continue to dig until the depth required by the design. In order to prevent the hole from collapsing and ensure the safety of operation, it is necessary to support the formwork and other supporting devices in the inner hole of the manual digging pile. The traditional formwor...

Problems solved by technology

In order to prevent the hole from collapsing and ensure the safety of operation, it is necessary to support the formwork and other supporting devices in the inner hole of the manual digging pile. The traditional formwork is generally supported by wood or steel formwork in the manual digging pile. The wooden formwork support system has low stability and the formwork The turnover utilization rate is low, and the formwork is time-consuming and wasteful; while the formwork of the steel formwork support system is heavy, it is inconvenient to transfer and assemble, and the assembly efficiency is low

[0003] In order to solve the above problems, the formwork for the pile hole is in the shape of a cone with a large top and a small bottom. When in use, it needs to be adjusted to the bottom for repeated use or when it is lifted up after demoulding, the formwork needs to be disassembled and then lowered separately. Finally, it is used after assembly in the pile mouth. This method of use brings great inconvenience to the construction and consumes work time; at this stage, steel formwork is used instead of wooden formwork. After using steel formwork, it not only has better strength and turnover It is unique and reusable; therefore, it is necessary to innovate a convenient manual digging pile retaining formwork to meet the construction needs
