Embodiment Construction

[0047] The following is attached Figure 1-3 The application is described in further detail.

[0048] The embodiment of the present application discloses a construction process of a constant-thickness cement-soil mixing continuous wall. refer to figure 1 , the construction process includes the following steps;

[0049]S1. Ascertain the geological conditions and survey the soil characteristics in the depth range;

[0050] When the geological conditions are verified, the depth of the rock layer is verified, the construction plan is designed according to the verified results, and the excavation plan is determined according to the characteristics of the soil.

[0051] S2. Carry out double-wheel milling and deep stirring cutting construction, and clean up the gravel in the groove of the underground diaphragm wall;

[0052] Choose the double-wheel milling and deep stirring equipment with strong cutting performance for cutting. Before cutting, dig out the soil layer and place it ...

Abstract

The invention relates to the field of underground continuous engineering, in particular to an equal-thickness cement-soil stirring continuous wall construction technology which comprises the following steps that geological conditions are ascertained, and soil texture characteristics in the depth range are investigated. Double-wheel milling deep stirring cutting construction is carried out, and broken stones in the underground diaphragm wall groove are cleaned. The cutting box is automatically driven for excavation. The underground diaphragm wall groove is filled with lightweight aggregate. A cement-soil stirring wall is built. The cutting box is pulled out and decomposed. According to the construction method, the construction problem of the equal-thickness cement-soil stirring continuous wall in the thick and high-strength dense and hard stratum is solved, the construction efficiency and quality of the underground continuous wall are improved, and material waste is reduced.

Description

technical field [0001] The present application relates to the field of underground continuous engineering, in particular to a construction technique for constant-thickness cement-soil mixing continuous walls. Background technique [0002] Diaphragm wall is a continuous wall constructed by using drilling equipment to form a groove section. It has high structural rigidity and can play a good supporting role. It is suitable for various geological conditions and can be used as a part of the main body of underground buildings. [0003] The cement-soil mixing continuous wall with equal thickness is different from the column-type cement-soil mixing continuous wall formed by the current traditional single-axis or multi-axis auger drilling machine. For cement-soil mixing continuous wall with constant thickness, first insert the chainsaw cutting tool into the foundation, excavate to the designed depth of the wall, then inject the curing agent, mix with the in-situ soil, and continue t...
