FOUNDATION GRAVEL SINKING APPARATUS OF SEA-BOTTOM FOR HARBOR FABRIC CONSTRUCTION

摘要

The present invention relates to the basic stone sinking device of the sea floor for the construction of a port structure. In particular, the construction period is shortened and the economical construction time is settled in the settlement of the basic stone used for dredging the sea floor when constructing the harbor structure. The purpose is to provide a means.;The present invention is provided with a hydraulic hammer device (10) having a hydraulic hammer 11 and a hammer guide 12 in the dredger 200 in submerging the foundation stone 100 in the dredging work, the hammer (11) While interlocking and configuring the steel pipe 20 to be hit by the hammer guide 10 perpendicularly, the lower end of the steel pipe 20 is a structure formed by integrally and widely forming the compaction plate 21 for the basic stone settling.;The present invention is very easy to complete the construction of the basic stone by performing the settlement and compaction work at the same time as the input of the basic stone. This significantly shortens the construction period as compared to the conventional means of leaving the load for a long time using the load of the loading block, and has a significant construction cost reduction effect. In addition, since the settlement occurs before mounting the caisson, the use of the standard frame for normal management, such as the alignment of the normal line is excluded, so the caisson normal management is easy and accordingly has excellent construction properties and stability.
