Embodiment
[0039] see Figure 1-2 , which demonstrates a method of uniform settlement of large-area backfill that ensures no gaps leading to subsidence during the backfill process;
[0040] The uniform settlement method of large-area backfill soil includes the following steps:
[0041] 1) At the bottom of the backfill pit 100, a vibrating column 1 with a top stopper 11 is evenly arranged on the top, and the first soil fall board 2 guided by the vibrating column 1 and The second soil falling plate 3, the area of the second soil falling plate 3 is larger than the first soil falling plate 2, and both are provided with soil falling holes (not shown in the figure), and the first soil falling plate 2 and the second soil falling plate Plates 3 are connected by connecting rods;
[0042] 2) The side wall of the backfill pit 100 is provided with a blocking block 4 corresponding to the second soil-falling plate 3, the vibrating column 1 is connected to the vibrating equipment (not shown in the ...

The invention discloses a large-area backfill soil uniform settling method. The large-area backfill soil uniform settling method comprises the following steps: multiple vibration columns with top end stoppers at the top ends are uniformly arranged at the pit bottom of a backfill pit; a first soil falling plate and a second soil falling plate with the vibration columns as guidance are arranged in the backfill pit in sequence from top to bottom; the area of the second soil filling plate is larger than the area of the first soil falling plate; soil falling holes are respectively formed in the first soil falling plate and the second soil falling plate; a stopper corresponding to the second soil falling plate is arranged on the side wall of the backfill pit; the vibration columns are connected with vibration equipment; the first soil falling plate is connected with lifting equipment; in the soil filling process, backfill soil enters the bottom of the backfill pit through the first soil falling plate and the second soil filling plate; at this time, the backfill soil enters the backfill pit through the soil falling holes respectively formed in the first soil falling plate and the second soil falling plate; the falling speed of the backfill soil is uniform; and in the falling process of the backfill soil, the vibration equipment vibrates through the vibration columns to guarantee the backfill uniformity of the backfill soil. The large-area backfill soil uniform settling method can guarantee no collapse gap in the backfill process.
Description
technical field [0001] The invention relates to the technical field of city square construction, in particular, it shows a method for uniform settlement of large-area backfill. Background technique [0002] In the field of urban square construction technology, some occasions need to hollow out the construction area for characteristic foundation construction and then backfill the excavated soil, especially for large-area backfill occasions. The current backfill method cannot guarantee the uniform settlement of the backfill soil. , leading to large gaps in the backfill soil, which may easily lead to subsidence of some areas of the square after completion. [0003] Therefore, it is necessary to provide a method for uniform settlement of large-area backfill to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a method for uniform settlement of large-area backfill that can ensure that there is no gap leading to coll...
