Description

Technical Field

[0001] The utility model relates to the technical field of grouting equipment, in particular to grouting equipment for local reinforcement of foundation. Background Art

[0002] Grouting equipment for localized foundation reinforcement is a tool used to strengthen a building's foundation. Grouting is a construction process that involves injecting a specific type of grouting material, such as cement slurry or polymer slurry, to fill voids or weak spots in the foundation, thereby enhancing its bearing capacity and stability. Grouting equipment for localized foundation reinforcement typically consists of a grouting pump, a piping system, control valves, and a control panel. The grouting pump draws grouting material from a storage container and delivers it through the piping system to the location in the foundation requiring reinforcement. The control valve regulates the grouting flow rate and pressure to ensure uniformity and stability. The control panel monitors the operating status and parameters of the grouting equipment.

[0003] The prior art provides a grouting device for foundation reinforcement (Announcement No.: CN217231778U), which includes a base, an N-shaped fixing frame fixedly mounted on the top of the base, and an adjustment frame disposed above the base and below the fixing frame. A groove is disposed on the inner surface of the fixing frame at a position corresponding to the adjustment frame. A screw rod is rotatably connected in the groove. A screw block is threadedly sleeved on the outer surface of the screw rod. The outer surface of the screw block is fixedly connected to the outer surface of the adjustment frame. A rotating wheel is fixedly mounted on the top of the screw rod and located above the fixing frame. A crank handle is disposed near the edge of the top of the rotating wheel. A pipe insertion hole and a slot are disposed on the adjustment frame. In the present utility model, by disposing the base, fixing frame, adjustment frame, screw rod, and other structures, a grouting pipe can be conveniently and stably inserted into the pile groove to be grouted. At the same time, the structural arrangement can ensure the stability of the grouting pipe positioning during grouting, and it is not easy to deviate or twist.

[0004] However, the device still has the following defects:

[0005] When the device is in use, the grouting pipe is directly inserted into the foundation grouting port for grouting, and the foundation grouting port position is not sealed. The unsealed foundation grouting port position will cause mud to overflow during the grouting process, causing waste and environmental pollution. Therefore, we need to propose a grouting equipment for local foundation reinforcement. Utility Model Content

The sealing ring is stuck on the ground outside the grouting port to seal the grouting port to prevent slurry from overflowing. When the grouting pipe is raised, the sealing ring leaves the ground under the tension of the tension spring, and the seal of the grouting port is released. During the lifting process of the sealing plate, the sliding rod plays a guiding role, and the limiting ring plays a limiting role on the sliding rod, so as to solve the problems raised in the above-mentioned background technology.
