Embodiment Construction
[0030] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:
[0031] A kind of earth-lifting type building foundation pit soil-lowering device in a narrow space, such as Figure 1-3 As shown, it includes a rail assembly 200 and a conveying assembly 300. The rail assembly 200 includes several rails 201 arranged side by side on the horizontal plane of the stepped foundation pit 100. In this embodiment, the foundation pit 100 is two stepped horizontal planes, and the rails 201 are respectively fixedly arranged on the upper and lower ladder horizontal planes of the foundation pit 100. The upper and lower rails 201 have the same rail width and are horizontally arranged in parallel. Each rail 201 is provided with a dozer 400, and the bulldozer 400 can be placed on the rail 201. Move horizontally. The soil lifter 400 is a commonly used structure in the field, and will not be described in detail here. The conveying assembly ...

The invention provides a soil lowering device for a narrow space soil lifting type building foundation pit. The soil lowering device comprises a track assembly and a conveying assembly, the track assembly is located on a horizontal plane of the foundation pit, the conveying assembly is arranged on the inclined plane of the foundation pit and comprises a plurality of apron plate conveying tables arranged in series and supporting frames fixed on the two sides of the apron plate conveying tables, the apron plate conveying tables are perpendicular to tracks, the uppermost ends of the apron plate conveying tables are connected with a soil lifter, the supporting frames are arranged on the inclined plane of the foundation pit and enable the apron plate conveying tables to be suspended, the apronplate conveying tables comprise a conveying belt and side plate strips symmetrically arranged in the width direction of the conveying belt, the conveying belt is provided with a through hole assemblyand a baffle assembly, the through hole assembly and the baffle plate assembly are located between the side plate strips, the through hole assembly is used for leaking slurry cement in soil, and a plurality of partition compartments are defined by the side plate strips and the baffle assembly for preventing soil from slipping. The invention further provides a using method of the soil lowering device of the narrow space soil lifting type building foundation pit. Soil in the foundation pit can be rapidly and safely conveyed.
Description
technical field [0001] The invention belongs to the technical field of foundation pit soil-lowering construction devices for building construction, and in particular relates to a narrow-space soil-lifting type building foundation pit soil-lowering device and a use method thereof. Background technique [0002] With the rapid development of urbanization, more and more buildings are appearing in major cities at a faster and faster speed. During engineering construction, the area and depth of building foundation pits show a trend of continuous expansion and deepening. The amount of "earth excavation" shows a continuous growth. While the "earth excavation" of building foundation pits has an impact on the quality of foundation pit construction, it also has an inhibitory effect on the "construction period and quality" of the overall construction of the building. For the construction of deep foundation pits of various buildings, especially the earthwork excavation project sites in ...
