Problems solved by technology
[0004] At present, although there are many studies on the excavation pile retaining wall, and many patent projects are proposed, many patents are mainly aimed at the splicing and forming of the prefabricated excavating pile retaining wall. Due to the lack of integrity of the spliced prefabricated retaining wall, its strength is limited. , especially for the construction of large-diameter excavated piles and deeper piles, there are still greater risks

The invention provides a soft soil foundation pile hole dado construction device and a construction method thereof. The soft soil foundation pile hole dado construction device comprises a supporting rack, the top part of which is horizontally provided with a fixing rack. The fixing rack is horizontally and movably provided with a first vertical elevating assembly and a second vertical elevating assembly. The bottom part of the first vertical elevating assembly is provided with a cement mortar spraying mechanism, and the bottom part of the second vertical elevating assembly is provided with aninstallation mechanism. The cement mortar spraying mechanism is used for spraying the cement mortar on the inner wall of the pile hole, and the installation mechanism is used for installing the reinforced assembly on the pile hole inner wall. The construction process is simple, and the stability and the safety performance of the dado can be improved, and human resource and material resource can besaved.
Description
technical field [0001] The invention relates to a construction device for pile hole wall protection, which belongs to the technical field of construction. Background technique [0002] Soft soil refers to fine-grained soil with high natural water content, large void ratio, high compressibility, and low shear strength deposited in coastal areas, lakes, valleys, and river beaches. It has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and The characteristics of physical and mechanical properties are quite different. [0003] Setting cast-in-place piles is one of the treatment methods for soft soil foundations. According to different hole-forming methods, cast-in-place piles can be divided into drilled cast-in-place piles, immersed tube cast-in-place piles, artificial...
