Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a large-scale anchor foundation self-propelled multifunctional working platform and a construction method. Background Art

[0002] At present, in the excavation and construction of large-scale foundation projects, underwater soil excavation, wall brushing or concrete pouring operations are often carried out due to the reasons of retaining structures and geological and hydrological conditions. However, traditional underwater soil excavation methods, such as air suction and rotary drilling rig soil excavation, generally require a large slag pool for mud sedimentation, and the air suction method generally turns the soil into mud, resulting in a large mud output and inconvenient handling. In the case of limited site, the mud must be screened or filtered, which has high requirements for post-supporting and may cause pollution to the water environment. If clay or reinforced solid obstacles are encountered during the excavation process, there will be problems of low efficiency and high excavation costs. In addition, traditional methods have difficulty in controlling the height difference of soil excavation at different depths underwater. At the same time, under the condition of large foundation size, it is difficult to brush the retaining structure, and the concrete pouring operation in the center of the foundation pit requires the cooperation of equipment such as tower crane hopper, which has high operation requirements and low efficiency.

[0003] For example, patent CN116145938A discloses a guide rail movable operating platform for grouting support of foundation pit slope, comprising: two translation guide rails for parallel fixing at the top and bottom of the slope; a climbing frame slidably mounted on the two translation guide rails at both ends, with the climbing guide rails fixed on the climbing frame; a climbing trolley slidably mounted on the climbing guide rails, the climbing trolley comprising a standing platform for construction personnel to stand and perform grouting operations, and an adjustable bracket slidably mounted on the climbing guide rails and fixed under the standing platform; sliding components are respectively connected to the two ends of the climbing frame, and the sliding components are slidably mounted on the translation guide rails; this solution can only be used for grouting construction in slope areas.

[0004] Therefore, there is an urgent need for a new underwater soil excavation method for large-scale foundations, which can efficiently and environmentally friendly carry out soil excavation operations for large-scale foundation projects and can achieve precise control of soil excavation height differences.
