Embodiment 1

[0039] Such as Figure 1-2 As shown, the present embodiment provides artificial excavation pile pre-reinforced retaining wall structure, including multiple groups of prefabricated waist beams, a plurality of reinforcement pipes 4, pile well locks 7 and cross braces 5;

[0040] The artificially dug pile pile well 1 is a rectangular structure.

[0041] Multiple groups of prefabricated waist beams are arranged at intervals along the depth direction of the pile well 1. One set of prefabricated waist beams includes two short-side waist beams 2 and two long-side waist beams 3. Two short sides and two long side waist beams 3 are respectively located on the two long sides of the pile shaft 1, and the two short side waist beams 2 and the two long side waist beams 3 are fixedly connected to form a rectangular frame structure. Specifically, multiple groups of prefabricated The distance between the waist beams along the depth direction of the pile well 1 is 0.5-1m. The two short side wai...

Embodiment 2

[0070] Such as image 3 As shown, the present embodiment provides a pre-reinforced retaining wall structure for artificial digging piles, including an annular waist beam 8, a plurality of reinforcement pipes 4 and pile well locks 7;

[0071] The artificially dug pile pile well 1 is a circular structure.

[0072] The annular waist beams 8 are arranged at intervals along the depth direction of the pile well 1. Specifically, the spacing of the annular waist beams 8 along the depth direction of the pile well 1 is 1-3m. Use I-beam, section steel or scrap steel rail, and grid steel frame can also be used.

[0073] A plurality of reinforcement pipes 4 are arranged at intervals along the circumferential direction of the pile well 1, fillers are poured in the reinforcement pipes 4, the tops of the reinforcement pipes 4 protrude from the pile well 1, and the reinforcement pipes 4 are fixedly connected with the annular waist beam 8. Specifically, the reinforcement pipes The layout, sha...

Abstract

The invention discloses a manual hole digging pile pre-reinforcing retaining wall structure and a construction process. The manual hole digging pile pre-reinforcing retaining wall structure comprisesa plurality of reinforcing pipes and a plurality of groups of prefabricated waist beams, wherein the plurality of groups of prefabricated waist beams are arranged on the inner wall of a pile well at intervals in the depth direction of the pile well; the plurality of reinforcing pipes are arranged on the inner wall of the pile well at intervals in the circumferential direction of the pile well; thereinforcing pipes are fixedly connected with the prefabricated waist beams; and fillers are poured in the reinforcing pipes. Through the structure, the waist beams and the reinforcing pipes are prefabricated structural parts, the reinforcing pipes are inserted into the periphery of the pile well before the pile well is constructed to pre-reinforce the pile well, the prefabricated waist beams andthe reinforcing pipes are connected into an integral frame to protect the pile well, the structure can be quickly installed in the pile well, reinforcing steel bar binding, formwork erection, formworkremoval and concrete pouring in the pile well are not needed, the construction of the pile well is not affected, the excavation of the pile well can be continuously implemented, the construction efficiency is improved, the fillers are poured in the reinforcing pipes to increase the bearing capacity, and the safety and stability of the construction are ensured.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a pre-reinforced retaining wall structure and construction technology of manual digging piles. Background technique [0002] In my country, manual excavation piles are widely used in engineering fields such as highways and railways because of their convenient construction, no need for large-scale mechanical equipment, and little interference with the surrounding environment during construction. During the construction process, in order to prevent pile wells from collapsing, flooding and other accidents that threaten the safety of underground personnel, concrete retaining walls are often used for protection. Usually after excavating 2m, the steel bars are bound underground, and the retaining wall is erected and cast in-situ. After the retaining wall concrete reaches its strength, the formwork is removed, and the excavation of the pile well is continued, and so on, until the design...
