Problems solved by technology
[0005] The purpose of the present invention is: in order to solve the problem of backfilling the pond by riprapping the silt, first all the silt is squeezed to the side of the fish pond through the gravel, and then the silt is removed, and part of the silt is easy to exist in the gap between the gravel Among them, the silt removal is not thorough, and the technical problem of the subgrade strength after the final filling is not high enough. The invention provides a construction method for pond backfilling with riprap and silting

Embodiment 1
[0019] This embodiment provides a pond backfill riprap construction method, including the following steps: select a center point N in the central area of the pond, and then pass through the center point N through three reference lines, and the angle between adjacent reference lines is 60°, the two ends of all reference lines form intersections with the edge of the pond, which are the intersections A, B, C, D, E, and F respectively, and then set up a sludge pump at the intersections A, B, C, D, E, and F pump, while throwing stones into the pond, the silt squeezed to the edge of the pond is sucked away by six silt pumps.
[0020] Furthermore, before throwing rocks, the surface vegetation and construction waste within the throwing range should be removed with an excavator, and at the same time cooperate with manual cleaning.

The invention discloses a construction method of throwing stones to packing sedimentation for pond backfilling and relates to the technical field of earthwork backfilling engineering. The constructionmethod comprises the following steps: selecting a center point N in a center area of a pond; then passing three datum lines through the center point N, wherein the included angle between two adjacentdatum lines is 60 degrees, and two ends of each datum line and the edges of the pond form intersections which are separately A, B, C, D, E and F; and arranging a sludge suction pump at the intersections A, B, C, D, E and F respectively, and pumping out sludge extruded to the edges of the pond through the six sludge suction pumps while throwing stones to the pond. The construction method disclosedby the invention has the advantages of being normative in operation and thorough to eliminate sludge and improving the roadbed strength.
Description
technical field [0001] The invention relates to the technical field of earthwork backfilling engineering, and more specifically relates to a construction method for pond backfilling by riprapping and squeezing silt. Background technique [0002] Rock dumping is a method of treating weak ground. A certain amount of gravel is thrown from the middle to both sides of the road base to squeeze the silt out of the road base to improve the strength of the road base. The gravel used should be large and hard to weather. Stones, generally not less than 0.15m in size. The rock-throwing method is often applicable to thick soft soil layers and lakes, ponds, rivers and other water-logged depressions that accumulate water all year round and are not easy to drain, and where there is no hard crust on the surface, and the soft soil has a large liquid index and a relatively thick layer. Thin and flaky stones can sink to the underlying hard layer. Compared with other reinforcement methods, the...
