Device for compacting sand soil foundation by librating

Abstract

The invention provides a device for vibrating compaction on sand soil foundation, wherein the device is basically in a basket type, comprising a rod mounting arm (16), on the bottom of which is vertically fixed with a plurality of rods (18) spaced in certain interval, and on the top center of which is fixed with a vibratory hammer (17). In addition, the vibratory hammer (17) is connected with a main winding wire rope (14) of a crawler crane (10), arranged with a metal holding piece (19) in a basket type, which is composed of the vibratory hammer (17), the rod mounting arm (16) and rods (18) in a way of moving up and down simultaneously, causing each rod (18) kept in certain interval, and allowing the rods (18) to move up and down. The rods (18)are tabled loosely in a loose jack (19a) of the rods (18) on the holding piece (19). The holding piece (19) is connected with an assistant winding wire rope (15) of the crawler crane (10).

Description

technical field [0001] The present invention relates to a device for vibrating sandy ground (hereinafter referred to as "rod compaction device", and its construction method is referred to as "rod compaction construction method"). In particular, the present invention relates to the following rod compaction device, wherein , in the construction of the rod pressing construction method using a plurality of steel pipe rods or H steel (both parties will be referred to as "rods" for short below), the verticality of each rod and a certain distance between the rods can be maintained, and the For uniform and effective reinforcement of sandy soil foundations. Background technique [0002] pass Figure 16 and Fig. 17, explain the rod compacting device in the past, in addition, through Fig. 18 (a) ~ Fig. 18 (g) and Figure 19 , the general construction method of rod pressing will be described. [0003] Figure 16 FIG. 17 is a front view showing an overall side view of a rod compacting ...

AI Technical Summary

Problems solved by technology

[0009] In addition, because the compaction effect of the above-mentioned general rod compaction construction method is mainly to carry out the compaction of the sandy soil foundation through the vibration of the above-mentioned uniaxial rod 5, the vibration of the transmission vibratory hammer 4 is limited to the periphery of the uniaxial rod 5.

In due course, the diameter of the reinforcement column for reinforcement and reinforcement is small, so if a wide area can be involved in the reinforcement of the foundation, it is necessary to repeatedly perform construction at small intervals, and thus, a problem of high construction cost arises
