Description

Technical Field

[0001] The utility model relates to the technical field of sludge solidification, in particular to an in-situ solidification device with a telescopic boom. Background Art

[0002] The marine intertidal zone is an important transitional zone between the ocean and the land. With the rapid development of cities, it has great development potential and has become an important land resource that can be utilized. It can not only provide basic support for reclamation and port construction, but also promote the local economic development and prosperity. However, the tidal flat sludge usually has the characteristics of high natural moisture content, high compressibility, high viscosity and low bearing capacity, and cannot be directly used as an excellent foundation. It needs to be treated. Generally, the in-situ solidification technology of the tidal flat can make the tidal flat hard and stable, improve its bearing capacity and stability, so as to meet the needs of various building and infrastructure construction.

[0003] For the coastal tidal flat sludge, through the shallow in-situ solidification process, using Zhongyan material curing agent can make the tidal flat sludge hard and stable, improve its bearing capacity and durability, and can improve the soft foundation into an excellent foundation, meeting the needs of various building and infrastructure construction, which has double significance for environmental protection and economic construction.

[0004] However, in the existing in-situ solidification technology of tidal flat sludge, the mechanical arm of the construction machinery with an in-situ mixing head is short, and the solidification depth is generally less than 5m. It is very difficult to meet the construction requirements for deeper in-situ solidification. If the solidification depth is increased, the length of the boom of the construction machinery needs to be increased, which is bound to increase the tonnage of the mechanical equipment, and then increase the bearing capacity requirements for the uncured tidal flat sludge, increasing the cost of other construction measures, and greatly reducing the economic benefits. And in the existing in-situ solidification technology of tidal flat sludge, the horizontal or vertical extension length of the mechanical equipment is limited, and the single construction range is small. It is necessary to continuously move the mechanical equipment to meet the solidification construction requirements of the new area, which greatly affects the construction efficiency in the block-by-block solidification method and affects the construction progress. In view of this, this application proposes an in-situ solidification device with a telescopic boom. Summary of the Utility Model

This increases the lateral or longitudinal extension length of the excavator boom 2, enlarges the construction range of a single excavation position of the excavator, greatly reduces the excavation frequency, improves construction efficiency, and makes the excavator more flexible in movement.

[0027] Among them, the primary boom 21 is fixedly installed on the top of the crawler excavator main body 1, the primary hydraulic rod 22 is rotatably installed on the top of the primary boom 21, one end of the primary boom 21 is rotatably installed with the secondary boom 23, and the movable end of the primary hydraulic rod 22 is rotatably installed on the top of the secondary boom 23.

Drill blades 621 are fixedly installed on the stirring drills 62. An outlet port 7 is formed at the central position of the stirring head 6. The stirring head 6 rotates, enabling the stirring head 6 to penetrate into the tidal flat silt, and materials are output through the outlet port 7 for in-situ solidification.

[0033] Embodiment 2: Please refer to Figure 4 , on the basis of Embodiment 1, a hydraulic lower arm 5 is sleeved on the surface of the hydraulic upper arm 4.
