[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1-6 As shown, the utility model provides a technical solution: a grouting mechanism for blocking water inrush from a ground source heat pump, comprising a grouting pipe 1, the grouting pipe 1 is connected to a water glass pump and a mud pump through a pipeline, the mud pump can be used to transport mud, the water glass pump is connected to a water glass tank through a pipeline, the water glass can be transported through the water glass pump, the mud pump is connected to the mud pipe through a pipeline, a plurality of grouting ports 3 are provided on one end of the grouting pipe 1, the grouting port 3 can be used to facilitate grouting operations, and the grouting pipe 1 is provided with a plurality of grouting ports 3. A protective structure 2 is provided at one end and on the grouting port 3. The protective structure 2 protects an outer sheath 21. The outer sheath 21 is provided outside the grouting pipe 1. A plurality of grouting ports 22 are provided on the outer sheath 21. The grouting ports 22 are staggered with the grouting ports 3. The outer sheath 21 is covered on the end of the grouting pipe so that the grouting ports 22 are staggered with the grouting ports 3, thereby closing the grouting ports 3. The outer sheath 21 can protect the grouting ports 3 and prevent the grouting ports 3 from being blocked. The outer sheath 21 is made of rubber material, and the rubber material can keep the outer sheath The sealing performance of the sleeve 21 and the grouting pipe is improved, thereby preventing liquid leakage from affecting the displacement control of the outer sleeve 21. The protective structure 2 is communicated with the connecting pipe 5, which passes through the grouting pipe 1 and is communicated with the sealing shell 4. The connecting pipe 5 can play a role in liquid transportation, so that the piston 61 can smoothly control the liquid to enter the outer sleeve 21. A scale 7 is fixedly connected to the top of the sealing shell 4. The adjustment position can be accurately known by the descending position of the pointer platform 63 and the scale 7. The sealing shell 4 is arranged on the grouting pipe 1, and a piston assembly 6 is arranged in the sealing shell 4. The piston assembly 6 includes a piston 61, which is arranged in the sealing shell 4. A connecting rod 62 is fixedly connected to the top of the piston 61. The connecting rod 62 passes through the sealing shell 4 upward and is fixedly connected to the pointer platform 63. The pointer platform 63 corresponds to the scale 7. A nut 64 is fixedly connected to the top of the pointer platform 63. A fixing bolt 65 is connected to the inner thread of the nut 64. The fixing bolt 65 is tightened on the scale 7 by rotating the fixing bolt 65, so that the position of the piston 61 can be fixed.

[0026] The working principle of the utility model is as follows: the ground source heat pump is implemented according to the conventional process. When the buried pipe is lowered, the grouting pipe 1 is tied to the buried pipe to ensure that the grouting pipe 1 is lowered to the water gushing blocking depth, and then the mud pump and the water glass pump are turned on. When mud or water glass comes out of the two pipes in the foundation pit, the pump is stopped, the valve is closed, and then the water glass valve is closed, and the mud valve and the grouting pipe valve are opened. At this time, cement is injected into the buried hole. When cement is reversed on the buried hole, the water glass valve is opened. After a certain period of time, the water glass pump is closed to complete the water gushing grouting.

[0027] During the grouting process, the connecting rod 62 can be driven downward by pressing the pointer platform 63, so that the piston 61 presses the slurry liquid into the connecting pipe 5 and the outer sheath 21, so that the outer sheath 21 moves downward and drives the slurry outlet 22 to move downward, so that the slurry outlet 22 corresponds to the aperture of the grouting port 3 for smooth grouting.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
