[0002] A soft foundation refers to a foundation composed of silt, silty soil, backfill, miscellaneous fill or highly compressible soil layers. It has low bearing capacity and high compressibility. It is prone to large settlement and deformation under load, making it difficult to meet the requirements of municipal engineering for foundation stability and deformation control.

[0003] There are still the following shortcomings:

[0004] When carrying out engineering construction on soft foundations, since the soft foundation construction needs to be reinforced, the commonly used soft foundation reinforcement method is to use a special drill bit to forcibly mix cement or lime and other curing agents with soft soil to form a cement-soil pile with a certain strength and stability, thereby enhancing the foundation bearing capacity and reducing settlement.

[0015] The present invention discloses a method for constructing a municipal engineering project on a soft foundation, comprising the following steps:

[0016] ① Move the construction device to a suitable location for soft foundation construction, and then insert specific soft foundation fixing nails into the fixed joint to fix the construction device;

[0017] ②. Connect one side of the connecting seat to the supply equipment of external cement, lime and other curing agents so that these materials can enter the mixing shaft through the connecting seat;

[0018] ③. By starting the construction motor B, the construction motor B and the construction shaft B are connected through a bevel gear transmission, and the construction motor B will drive the mixing shaft to rotate through the construction shaft B;

[0019] ④. By starting the construction motor A, the construction motor A will drive the adjustment screw to rotate through the construction shaft A. The rotation of the adjustment screw will drive the construction seat to move downward, so that the construction seat drives the mixing shaft to penetrate the ground. The mixing shaft contacts the ground and sprays out a curing agent such as cement or lime to merge with the soft soil on the ground, thereby forming a certain cement-soil pile body;

[0020] ⑤. By starting the adjustment cylinder, one end of the piston rod of the adjustment cylinder is fixedly connected to the adjustment head. The adjustment cylinder will drive the adjustment bracket to move, so that the construction position of the stirring shaft on the adjustment bracket will change. Then, the construction position of the stirring shaft can be adjusted as needed, thereby improving construction convenience;

[0021] ⑥. When multiple sets of construction devices are required to be used together, the fixing block of the matching pillar can be inserted into the fixing slot, and then fixed by fixing screws between the fixing block and the fixing slot. Four sets of construction devices can be installed and fixed on the matching pillar. The simultaneous use of four sets of construction devices can form a larger cement soil pile body, thereby effectively improving the construction speed.

[0022] The hydraulic gate hoist with controllable steering provided by the present invention has the following beneficial effects:

[0023] Through the cooperation between the construction base and the adjustment bracket, when the construction device is firmly fixed, the adjustment cylinder can be started to enter the construction adjustment mode. The adjustment cylinder is the core driving component, and a high-strength and stable fixed connection method is adopted between one end of the piston rod and the adjustment head to ensure the accuracy and efficiency of power transmission. As the adjustment cylinder is started, the piston rod begins to make reciprocating linear motion. This movement directly drives the adjustment bracket to move horizontally, which enables the construction position of the mixing shaft on the adjustment bracket to be accurately and flexibly changed. In the actual construction process, different geological conditions, construction requirements and project layouts often require the mixing shaft to be in different positions to achieve the best mixing effect. By adjusting the drive of the cylinder, construction personnel do not need to perform tedious manual disassembly and reinstallation. They only need to easily operate the control equipment to quickly and accurately adjust the position of the mixing shaft, which greatly improves the convenience of construction and saves a lot of time and labor costs, thereby improving the uniformity and quality of mixing, making the cement soil more fully mixed, laying a solid foundation for subsequent construction processes, and effectively improving the quality and stability of the entire project.

[0024] When the construction task is large-scale and requires multiple sets of construction devices to work together, the construction workers only need to insert the fixing block of the matching pillar into the fixing slot, and then firmly fix the fixing screws between the fixing block and the fixing slot. This installation method is not only easy to operate, but also has a stable and reliable connection. It can withstand a large construction load and ensure the safety and stability of multiple sets of construction devices during coordinated use. The fixed bracket on the matching pillar gives it a strong load-bearing capacity. Four sets of construction devices can be installed and fixed on it. When the construction position of the construction device needs to be adjusted, the construction hoisting equipment only needs to be connected to the hoisting head set on the matching pillar to easily realize the overall hoisting of the matching pillar. The matching pillar serves as an overall mobile platform, which can simultaneously drive the four sets of construction devices installed on it. The devices move synchronously, avoiding the tedious process of hoisting and adjusting the construction devices one by one, greatly improving construction efficiency and reducing uncertainty and errors in the construction process. Secondly, in the formal construction phase, four groups of construction devices are put into use at the same time. They cooperate with each other and work together to form a mixing area with a larger area and depth, thereby quickly forming a larger cement soil pile body. This large-scale construction method effectively improves the construction speed, shortens the project cycle, enables the project to be put into use faster, and generates economic and social benefits. At the same time, since the four groups of construction devices work at the same time, the uniformity and continuity of mixing are better guaranteed, and the cement soil pile body formed is of higher quality and greater strength, which can better meet the bearing requirements of the project and improve the safety and durability of the entire project.

10. A construction method for a municipal engineering construction device on soft foundation according to any one of claims 1 to 9, characterized in that: The following steps are involved: ①, by moving the construction device to a suitable location for construction on the soft foundation, and then inserting a specific soft foundation fixing nail into the fixing joint (106), the construction device is fixed; ②, connecting one side of the connecting seat (212) to an external supply device for a curing agent such as cement or lime, so that these materials can enter the stirring shaft (211) through the connecting seat (212); ③. By starting the construction motor B (208), the construction motor B (208) and the construction shaft B (210) are connected via a bevel gear transmission, and the construction motor B (208) drives the stirring shaft (211) to rotate via the construction shaft B (210); ④. By starting the construction motor A (202), the construction motor A (202) drives the adjusting screw (213) to rotate via the construction rotating shaft A (203). The rotation of the adjusting screw (213) drives the construction seat (206) to move downward, so that the construction seat (206) drives the stirring shaft (211) to be inserted into the ground. The stirring shaft (211) contacts the ground and sprays a curing agent such as cement or lime to merge with the soft soil on the ground, thereby forming a certain cement-soil pile body. ⑤. By starting the adjustment cylinder (105), one end of the piston rod of the adjustment cylinder (105) is fixedly connected to the adjustment head (204), and the adjustment cylinder (105) drives the adjustment bracket (2) to move, so that the construction position of the stirring shaft (211) on the adjustment bracket (2) changes, and the construction position of the stirring shaft (211) can be adjusted as needed, thereby improving construction convenience; ⑥. When multiple sets of construction devices are required to be used in conjunction with each other, the fixing block (304) of the matching pillar (3) can be inserted into the fixing slot (104), and then fixed by fixing screws between the fixing block (304) and the fixing slot (104). Four sets of construction devices can be installed and fixed on the matching pillar (3). The simultaneous use of the four sets of construction devices can form a larger cement soil pile body, thereby effectively improving the construction speed.
