Description

Technical Field

[0001] The present application relates to the field of foundation repair, and in particular to a device for repairing cracks in building foundations. Background Art

[0002] The foundation refers to the part of the soil that bears the influence of the superstructure load. The soil or rock under the foundation that bears the entire load of the building is called the foundation. The foundation that has been artificially treated or improved is called an artificial foundation. When the geological condition of the soil layer is good and the bearing capacity is strong, it is called a natural foundation.

[0003] In order to improve the good supporting effect of the foundation, concrete will be poured on the foundation during construction. The foundation and concrete form a whole, which is convenient for building on the foundation. When the foundation is in use, there is a situation where the soil layer sinks or there are voids, which will cause cracks in the concrete on the foundation. In order to ensure the safety and stability of the building, the cracks will be repaired. The repair method is generally to drill a hole above the crack to connect the hole with the void under the ground. Then the operator holds the injection device, extends the feed pipe of the injection device into the hole, and injects the repair agent into it for grouting repair.

[0004] The feed pipe of the existing injection device is generally a long feed pipe, which can only be inserted vertically into the drilled hole. The repair agent will first fill the hole before flowing into the crack, which causes the repair agent to flow slowly into the crack and there is a possibility that the repair agent may not flow into place.
