Problems solved by technology

[0003] In the construction of dynamic ramming method, due to reasons such as site dredging and backfilling, 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] The step S2 can also ascertain the attitude of the rammer through an ultrasonic induction scanner, and the specific steps are as follows:

[0042] Step A1, construct...

Abstract

The invention provides a salvaging construction method for a dynamic compaction hammer. The salvaging construction method comprises the following steps that S1, a position of the compaction hammer isdetected; S2, a posture of the compaction hammer is detected; S3, a first-stage caisson is arranged in soft soil of an upper portion of the compaction hammer, and the soft soil is excavated in the first-stage caisson; and S4, excavating is carried out until a handle of the compaction hammer is exposed, and the compaction hammer is hoisted to a safe area. According to the salvaging construction method of the dynamic compaction hammer, the soft soil can be prevented from flowing in from a digging side direction in an excavating process, the position and posture changes of the compaction hammer are reduced, the engineering amount in a salvaging process can be reduced, and the salvaging efficiency is improved, so that the engineering progress is guaranteed.

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] The dynamic compaction method is widely used in fields such as land reclamation projects and land reclamation projects because of its economical, fast and efficient advantages. [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 The construction period of the project caused heavy economic losses. In order to recover economic loss and ensure that the project is completed on time, the rammer in the weak soil must be salvaged fast. Contents of the invention [0004] In order to overcome the above problem...
