Dynamic compaction replacement foundation treatment method and device

Abstract

The invention provides a dynamic compaction replacement foundation treatment method which comprises the steps that S1, a site is leveled, and the elevation of a working face is measured; S2, a pit at the ramming point is dug, the pit is checked and filled; S3, after a construction scheme is determined through trial tamping, point tamping is conducted on all pit points on a large scale; S4, leveling and compacting are conducted through full compaction, the elevation of the working face is measured again after full compaction, the compaction settlement amount is determined, and a cushion layer is laid; and S5, the reinforcement effect is inspected and accepted. The invention further provides a dynamic compaction replacement foundation treatment device, the excavation head of the device is matched with the image obtaining assembly to obtain the image information of the soil layer in the compaction pit, the construction scheme can be conveniently adjusted in time, and the construction efficiency is improved. According to the dynamic compaction replacement foundation treatment method provided by the embodiment of the invention, the problem that the dynamic compaction replacement foundation treatment effect is poor due to the fact that the penetrating power of a dynamic compaction replacement material is poor for a special complex geological foundation is solved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a treatment method and device for dynamic compaction replacement ground. Background technique [0002] The dynamic compaction replacement method is suitable for the treatment of highly saturated silt, soft plastic to flow plastic silty clay, and the replacement material usually requires the use of well-graded block stones, crushed stones and other hard coarse-grained materials, which are commonly used foundations for engineering construction processing means. Due to complex geological conditions, drastic stratum changes and dynamic compaction replacement materials in some construction projects in Southwest China, the ground treatment effect of dynamic compaction replacement is poor and cannot meet the design requirements; the construction efficiency of dynamic compaction replacement is low and cannot meet the construction period requirements; dynamic compaction r...

Problems solved by technology

Due to complex geological conditions, drastic stratum changes and dynamic compaction replacement materials in some construction projects in Southwest China, the ground treatment effect of dynamic compaction replacement is poor and cannot meet the design requirements; the construction efficiency of dynamic compaction replacement is low and cannot meet the construction period requirements; dynamic compaction replacement Problems such as large dispersion of material consumption and difficulty in cost control

[0003] At present, the existing dynamic compaction replacement method cannot solve the above problems, so it is urgent to design a method and device to solve the problem of poor treatment effect of dynamic compaction replacement foundation due to special complex geological foundations and poor penetration of dynamic compaction replacement materials
