Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0018] The present invention fully considers meeting the design requirements of manual-dug piles, and sets precipitation wells near the manual-dug piles for centralized drainage to provide a construction environment where there is basically no groundwater when constructing manual-dug piles. When constructing manual-dug piles, 120mm Thick concrete zigzag retaining wall, pile body concrete pouring does not require high cost investment of underwater pouring concrete.

[0019] refer to figure 1 , figure 2 , a kind of well point of the present invention lowers the method for underground water level construction manual hole digging pile and the concrete steps are:

Abstract

The invention relates to the technical field of a construction engineering technology, in particular to a method for method for constructing an artifical dug pile at a reduced well point ground water level, comprising the following steps: a drainage ditch is arranged on the upper periphery of the plane layout of an artificial dug pile; carrying out dewatering well construction at the periphery of the artificial dug pile; pumping water in the dewatering well by a submersible pump; adopting a sawtooth concrete retaining wall for the artificial dug pile; and directly pouring the concrete by a lower reinforcement cage after the artificial dug pile retaining wall is formed. In the invention, the dewatering well is arranged near the artifical dug pile for draining concentrately, and provides a safe construction environment basically having no underground water when the artificial dug pipe is constructed; and the traditional method for constructing single water drawing and chambering in the pile in the process of constructing the artificial dug pile is changed, and high-cost investment of pouring the concrete is not needed. The relative traditional method of the invention lowers the cost and the operation difficulty, and improves the construction efficiency and the safe assurance coefficient.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for manually digging hole piles. Background technique [0002] Manual excavation pile is a pile foundation project that must be designed in all buildings because the foundation soil is soft and cannot reach the design bearing capacity. The method of manually digging piles with a lot of groundwater in traditional construction is: directly dig the hole, and when the next section is dug, there is too much water, and one water pump cannot meet the drainage needs, so the hole is reamed, and more than two water pumps are used to pump water. The disadvantages of this construction method are: the amount of concrete used in the pile body is increased after the hole is expanded, and other corresponding construction materials are wasted; The high cost input of pouring concrete. Therefore, the high cost of constructing this type of hole-digging pile and the safety...
