Prefabricated cylinder retaining wall for manual hole digging pile and construction method

Abstract

The invention relates to a prefabricated cylinder retaining wall for a manual hole digging pile. The prefabricated cylinder retaining wall comprises a prefabricated cylinder, wherein an annular inserting groove is coaxially formed in the outer edge of one end surface of the prefabricated cylinder, a plurality of inserting rods are movably arranged in the annular inserting groove at equal intervals in a penetrating mode, the axis direction of each inserting rod faces the axis of the prefabricated cylinder, one ends of the inserting rods penetrate into the inner wall of the prefabricated cylinder, an accommodating groove is formed in the inner wall of the prefabricated cylinder in the axis direction of the prefabricated cylinder, springs used for being connected with the inserting rods and enabling the inserting rods to penetrate out of the inner wall of the prefabricated cylinder are arranged in the inner wall of the accommodating groove in the axis direction of the accommodating groove in a penetrating mode, wedge-shaped ends are arranged at the ends, penetrating out of the inner wall of the prefabricated cylinder, of the inserting rods, a plurality of inserting plates are arranged on the outer edge of the end surface, away from the annular inserting groove, of the prefabricated cylinder in the circumferential direction at equal intervals, through holes are formed in the inserting plates in a penetrating mode, and the axes of the through holes face the axis of the prefabricated cylinder. The prefabricated cylinder retaining wall has the effect of shortening the construction period.

Description

technical field [0001] The present application relates to the field of building construction, and in particular to a prefabricated tube retaining wall of artificial digging piles and a construction method. Background technique [0002] At present, manual digging piles are the reinforced concrete piles that are excavated by manpower and poured on site. In most cases, manual excavation piles need to be equipped with concrete retaining walls to protect the stability of the holes. At present, the retaining walls are generally cast-in-place reinforced concrete structures, which need to be excavated and poured again. Because the reinforced concrete structure is formed slowly, the construction period is often delayed in the concrete retaining wall work. [0003] With regard to the above-mentioned related technologies, the inventor believes that there are defects such as slow formation of concrete retaining walls and delayed construction period. Contents of the invention [0004...
