In addition, the connecting pipe is easily damaged when the drainage pipe is driven, which affects the subsequent drainage effect. Therefore, a rapid solidification treatment device for soft soil foundation of municipal roads is provided. Utility Model Content

[0025] refer to Figure 1 , Figure 2 and Figure 4A bearing seat 6 is fixedly installed near the middle of the inner bottom surface of the drainage pipe pile 1, and a mounting shaft 7 is fixedly installed in the middle of the bearing seat 6. A plurality of mounting discs 8 are fixedly installed on the outer surface of the mounting shaft 7, and a hinge seat 2 9 is symmetrically fixedly installed on the outer surfaces of the plurality of mounting discs 8. A circular push rod 10 is hinged inside the hinge seat 2 9, and one end of the circular push rod 10 away from the hinge seat 2 9 is hinged to the inside of the hinge seat 1 5; through the setting of the bearing seat 6, it is convenient to drive the mounting shaft 7 and the mounting disc 8 to rotate. When the mounting disc 8 rotates, the hinge seat 2 9 will drive the circular push rod 10 to move forward, so that it is convenient to push the hinge seat 1 5 and the connecting drainage pipe 3 forward, so that the connecting drainage pipe 3 extends out from the inside of the drainage pipe pile 1, and multiple mounting discs 8, hinge seats 2 9 and circular push rods 10 can be installed in a staggered manner, so that multiple connecting drainage pipes 3 can be extended to improve the drainage efficiency.

[0026] refer to Figure 1 , Figure 2 and Figure 3 A sealing pipe cover 11 is fixedly installed on the top of the drainage pipe pile 1 by means of provided bolts, a drainage pipe 12 is passed through and fixedly installed on the top surface of the sealing pipe cover 11, the bottom end of the drainage pipe 12 extends to the interior of the drainage pipe pile 1, a connecting pipe 13 is fixedly installed on the top of the drainage pipe 12 by means of a provided flange connection plate, and one end of the connecting pipe 13 away from the drainage pipe 12 is connected to an external water pump; the user starts the external water pump, so that the connecting pipe 13 and the drainage pipe 12 generate negative pressure, thereby facilitating the extraction of water from the drainage pipe pile 1.

[0027] The implementation principle of the embodiment of the municipal road soft soil foundation rapid solidification treatment device of the present application is as follows: under normal conditions, the connecting drainage pipe 3 is located inside the drainage pipe pile 1 to ensure that the connecting drainage pipe 3 is not damaged during transportation. When it is necessary to drain the soft soil foundation of the road, first use a pile driver or corresponding equipment to dig the drainage pipe pile 1 into the soil. Then, the operator uses a motor to cooperate with a coupling to connect with the top of the installation shaft 7, so that the motor drives the installation shaft 7 and the installation disc 8 to rotate. At this time, the hinge seat 2 9 will push the connecting push rod 10 to move forward, so that the connecting drainage pipe 3 extends outward from the inside of the drainage pipe pile 1 to access the water flow in the soft soil foundation. The water flows into the connecting drainage pipe 3 and the drainage pipe pile 1 through the water inlet circular hole. Subsequently, the external water pump is started to discharge the water inside the drainage pipe pile 1 through the drainage pipe 12. This process significantly improves the drainage efficiency of the soft soil foundation of the road.

[0028] After the drainage is completed, the operator starts the motor in reverse, so that the connecting drainage pipe 3 is retracted into the drainage pipe pile 1 under the drive of the connecting push rod 10, so as to facilitate the subsequent removal of the drainage pipe pile 1 from the soft soil foundation of the road. After the drainage pipe pile 1 is removed, the operator can drive a hollow pile into the hole and add materials such as chemical reinforcement agents or cement slurry to promote these substances to diffuse from around the hole, achieve rapid solidification, and enhance the stability of the road foundation;

[0029] The device has a simple structure and a convenient operation process. By connecting the drainage pipe 3 and inserting it into the soft soil foundation of the road, it can not only effectively remove the moisture in the soft soil foundation, but also increase the friction between the drainage pipe pile 1 and the soil, so that the drainage pipe pile 1 will not easily tilt after being driven into the soft soil foundation of the road, thereby improving the stability of the drainage pipe pile.
