Background
While high-rise buildings are developed to unprecedented scale, the development and utilization of underground spaces are more and more paid more attention.
The scale, depth and complexity of a large number of foundation pit projects faced by urban construction and transformation are continuously increased. Especially in soft soil areas, the overall engineering properties are extremely poor due to the low shear strength, low permeability, high water content, high compressibility of soft soil.
While the coastal areas with developed economy, the delta areas of the Yangtze river and the inland coastal areas along the river are widely distributed with soft soil.
These areas have in recent years had to exploit the urban underground space due to the increasing crowding of it.
However, when construction is carried out in urban areas, the direct face is a complex surrounding environment, and therefore safety problems are prominent.
In addition, environmental influence is increased by the concern, and difficulty is brought to soft soil foundation pit engineering.
Due to the special geological structure of the soft soil, the problems of overlarge lateral displacement of the enclosure body, subsidence of the surrounding earth surface, pit bottom uplift and the like often occur in the soft soil foundation due to improper design of foundation pit enclosure, so that the stability of the foundation pit and the safety and normal use of adjacent facilities are influenced.
Therefore, the selection of the foundation pit support structure in the soft soil foundation pit engineering is of great importance, the prior support structure generally adopts deep mixing piles, steel sheet piles, underground continuous walls, cast-in-situ bored piles and the like, but the single support form can not meet the actual engineering requirements in consideration of the characteristics of the soft soil foundation pit, and a foundation pit composite support system is gradually built. The principle of the composite supporting system is as follows: in a plurality of support forms, the optimal combination is searched for so as to achieve the purposes of reasonable technology, safety, feasibility, economy and slope stability. Compared with a single mode, the combined type soft soil foundation pit supporting structure has the advantages that two or more supporting structures are combined to be used, respective advantages are exerted according to the characteristics of the soft soil foundation pit, the purpose of maintaining the stability of the foundation pit can be achieved, and the combined type soft soil foundation pit supporting structure is more economical and reasonable.

The pile descending quantity is less, and the efficiency of the three shaft and the two shafts is lower;
secondly, the pile is not well fixed when being driven, and the function of driving the cement soil mixing pile to adjust the angle is achieved;
the third pile driver adopts tire movement, so that the ground is easily extruded and deformed to be not beneficial to pile driving;
therefore, the high-stability five-axis cement soil mixing pile H-shaped steel positioning device and the construction method are designed to optimize the problems.
