Description

Technical Field

[0001] The invention relates to the technical field of silt foundation solidification, in particular to silt foundation solidification equipment. Background Art

[0002] Substation site selection often encounters complex geological conditions, such as many soft foundations and abundant groundwater, among which soft soil foundation is the most common. There is often a silt soil layer on the upper part of this type of foundation, which is mostly soft plastic or loose, with high compressibility, low strength, and severe earthquake liquefaction level. In addition, the thickness of the silt layer is relatively large. Under the action of external loads such as site filling, it will produce a large amount of settlement, and the settlement will last for a long time, which poses a great hidden danger to the normal operation of the substation. In the past, substation projects usually used the replacement method to deal with such soft soil foundations, but the replacement method has a long construction period, consumes a lot of resources, and has high construction costs. In addition, the silt is difficult to excavate, transport, and subsequently treat, and secondary pollution is easy to occur during the period, wasting soil resources and damaging the natural environment. The soft soil solidification technology can effectively solve such problems. This technology uses a curing agent to solidify soft soil and other soils in situ, so that the strength of the soil can be improved to a certain extent, making it a high-quality foundation material with good tensile strength, fatigue resistance and water stability. It meets the needs of substation project construction and solves the secondary pollution problem caused by sludge transportation and stacking.

[0003] For example, the patent document with patent publication number CN218465662U discloses a sludge in-situ solidification device, which belongs to the field of sludge solidification technology, including a stirring shaft, a triangular drill bit is rotatably connected to the bottom of the stirring shaft, a bidirectional spiral reamer is fixed on the outer surface of the triangular drill bit, a powerful stirring head is rotatably connected to the stirring shaft on all sides, a hydraulic telescopic rod is fixedly connected to the top of the stirring shaft, and a crawler excavator is fixedly connected to the end of the hydraulic telescopic rod away from the stirring shaft. However, its spray head is installed on the stirring head, which easily causes sludge to block the stirring head, and its stirring range is limited, and the sludge solidification efficiency is low.

[0004] In order to solve the problem of clogging of the sprinkler head, the patent document with patent publication number CN217438894U discloses an anti-clogging sprinkler device for in-situ soil solidification, including a basic tube, a head sleeve and a driver, the head sleeve is slidably sleeved on the front part of the basic tube, and the driver is used to drive the head sleeve and the basic tube to produce relative movement; a long strip of insert is arranged at the front end of the basic tube, and the tail end of the basic tube is connected to the powder spraying pipeline. When working, when the sludge enters the head sleeve of the sprinkler device and causes clogging, the action rod of the control driver is contracted, and the head sleeve is driven to move backward relative to the basic tube, so that the insert at the front end of the basic tube is inserted into the sludge blocked in the head sleeve, and then the action rod of the driver is extended, and the head sleeve is driven to move forward relative to the basic tube to return to the initial position, so that the insert at the front end of the basic tube is separated from the sludge and a plurality of through holes are formed in the sludge, at which time the liquid in the powder spraying pipeline can be sprayed outward through the through holes in the sludge, and the sludge blocked in the head sleeve is gradually discharged outward. However, it requires the use of additional driving devices to remove sludge. The redundant driving devices increase the complexity of the structure and increase the failure rate.

[0005] The existing silt foundation solidification equipment still has the following defects: 1. The stirring range is limited and the stirring float is small; 2. The sprinkler head is easily blocked, and installing a drive device to remove the silt will increase the failure rate. Summary of the invention
