Example Embodiment

[0045] The present invention will be further described in detail below in conjunction with the drawings.

[0046] Reference figure 1 , Is a construction method of a manual digging pile and a manual digging pile disclosed in the present invention, which includes a protective wall and a steel cage, and the protective wall is arranged in the pile hole 35. In this embodiment, a plurality of protective walls can be provided, and they are arranged along the axial length of the pile hole 35 and spliced ​​in sequence. Each protective wall is composed of four arc-shaped steel plates 2 spliced ​​along the circumference of the pile hole wall, and surrounds a cylindrical grouting channel 1, which is used for placing steel cages and for pouring concrete grout.

[0047] Reference figure 2 with image 3 Specifically, in the above-mentioned protective wall, two adjacent arc-shaped steel plates 2 are provided with splicing convex strips 8 and splicing grooves 9 corresponding to the splicing convex...

Abstract

The invention relates to the technical field of engineering construction, in particular to a manual hole digging pile and a construction method of the manual hole digging pile. The manual hole diggingpile comprises a protecting wall and a reinforcement cage. The protecting wall is arranged in a pile hole and is composed of a plurality of arc-shaped steel plates in a circumferential direction of apore wall of the pile hole to encircle a grouting channel, the grouting channel is used for placing the reinforcement cage, a supporting part for fixing the arc-shaped steel plate is arranged betweeneach arc-shaped steel plate and the pore wall of the pile hole, the reinforcement cage is formed by stacking a plurality of unit cages in the grouting channel successively, a guide ring is arranged at the bottom of each unit cage, a plurality of connecting assemblies are connected between the unit cages and the guide rings, each unit cage is internally provided with a vertically arranged guide bar, the guide bar stretches outside one end of the unit cage, and when two adjacent unit cages are stacked together, the guide ring is arranged on the guide bar in a sleeving manner. The reinforcementcage can be suitable for depth of different hole digging piles, so that the manual hole digging pile is relatively high in flexibility and the invention provides the construction method for construction.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a manual hole-digging pile and a construction method for the manual hole-digging pile. Background technique [0002] Manual digging pile is a kind of reinforced concrete pile that is excavated by manpower and poured on site. Manual excavation piles are generally used for superstructures with fewer bearing floors and higher pressure. [0003] In the existing technology, the manual hole-digging pile is first excavated at the required position to form the pile hole. When it is dug to a certain depth, in order to avoid the hole collapse, a retaining wall is fixed on the hole wall of the pile hole, and the spoil is transported to the pile hole by lifting equipment. Outside the pile hole, continue to dig soil and install the retaining wall, align the prefabricated steel cage with the pile hole and put it into the pile hole, and finally pour concrete slurry to form the...
