Problems solved by technology

[0003] In the construction of dynamic ramming method, due to reasons such as site dredging, uneven thickness of backfill, and uneven thickness of soft soil with complex geological conditions, it is easy to cause the rammer to penetrate the surface covering layer and sink into the soft soil layer, resulting in forced suspension of project construction and delays construction period, resulting in major economic losses

Embodiment Construction

[0035] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] This embodiment provides a kind of salvage method of a dynamic rammer, such as figure 1 shown, including the following steps:

[0037] Step S1: Find out the position of the rammer 1;

[0038] Step S2: Ascertain the posture of the rammer 1;

[0039] Step S3: sinking the primary caisson 3 in the soft soil 2 above the rammer 1, and excavating the soft soil 2 in the primary caisson 3;

[0040] Step S4: dig until the handle of the rammer 1 is exposed, and lift the rammer 1 to a safe area.

[0041] In step S2, the attitude of the rammer is ascertained by an ultrasonic induction scanner, and the specific steps are as follows:

[0042] Step A1, construct pixel va...

Abstract

The invention provides a salvage method of a powerful rammer, comprising the following steps: step S1: find out the position of the rammer; step S2: find out the attitude of the rammer; step S3: set a first-stage caisson in the soft soil above the rammer, Excavate soft soil in the first-level caisson; step S4: dig until the handle of the rammer is exposed, and lift the rammer to a safe area. The salvage method of the strong rammer provided by the present invention can prevent the soft soil from pouring in from the side of the excavation pit during the excavation process, reduce the position and posture changes of the rammer, reduce the engineering amount of the salvage process, and improve the salvage efficiency to ensure project progress.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a salvage method of a dynamic rammer. Background technique [0002] With the development of society and economy, land resources are becoming more and more tense. Land reclamation projects and mountain reclamation projects (reinforcement and treatment projects for backfilling on soft soil at the bottom of valleys) have eased the tense situation of land resources; The number of ground projects is increasing, and the backfilling soil foundation treatment technology is developing rapidly. The dynamic compaction method is rapidly promoted in my country's coastal areas along the river, central and western mountainous areas, and areas along the Belt and Road because of its economical, fast, and efficient advantages; [0003] In the construction of dynamic ramming method, due to reasons such as site dredging, uneven backfill thickness, and uneven thickness of soft soil with complex geolog...
