Problems solved by technology

[0004] However, since the telescopic guide rod is composed of multi-section guide rods, and works in an environment where gravel, sand, and mud are mixed and the lower part is connected to large-scale vibrating equipment, once the mud and the sand and gravel in it enter the inner and outer guide rods If the telescopic guide rod is stuck in the gap, the vibro impactor will be buried in the hole, which will cause the failure of the vibro impact gravel pile construction and cause huge losses.

Embodiment Construction

[0050] Such as figure 1 , figure 2 As shown, it is a schematic structural diagram of the vibro-crushing pile machine provided by the present invention. It can be seen from the figure that the vibro-crushing pile machine includes: a crane system 400, an automatic feeding system 300, a drill pipe system 100 and a vibro-concentrator system 200 , the cable hoisting device 302, the water pipe hoisting device 304, the gas pipe hoisting device 301 and the wire rope hoisting device 303 of the automatic feed system are synchronously fed, wherein the axial length of the guide rod 101 in the drill pipe system is adjustable, In order to change the lowering or lifting position of the vibrator system relative to the ground; wherein, the automatic feeding system is installed at the rear of the crane 401 in the crane system 400, and is used as a counterweight of the crane.

[0051] Specifically, such as Figure 1-Figure 3 As shown, the cable hoisting device 302, the water pipe hoisting dev...

Abstract

The invention discloses a vibro-replacement stone column machine and a construction method thereof. The vibro-replacement stone column machine comprises a crane system, an automatic feeding system, a drill rod system and a vibrator system. The method includes the steps that when the vibro-replacement stone column machine conducts vibrator ultra-deep construction, a steel wire rope winding device enables a vibrator connected below a telescopic guide rod to descend gradually by releasing sleeves in a column hole of the telescopic guide rod layer by layer; while the steel wire rope winding device enables the sleeves in the telescopic guide rod to be released layer by layer, a cable winding device, a water pipe winding device and a gas pipe winding device synchronously release a cable, a water pipe and a gas pipe placed in the telescopic guide rod; the vibrator vibrates downwards continuously through electric power, clear water and gas supplied by the cable, the water pipe and the gas pipe which descend synchronously along with the vibrator, so that an ultra-deep vibro-replacement stone column hole is formed; after the ultra-depth vibro-replacement stone column hole reaches a preset depth, the hole is cleaned up, stone is thrown into the hole, a column can be manufactured in a vibration and compaction mode, and thus an ultra-depth vibro-replacement stone column can be formed.

Description

technical field [0001] The invention relates to the technical field of foundation engineering construction, in particular to a vibrating gravel pile machine and a construction method for realizing ultra-deep densification. Background technique [0002] In the soft soil foundation reinforcement treatment project, the vibratory crushed stone pile technology has been widely used due to its advantages of outstanding construction quality, simple construction process, low construction cost, and wide source of filling materials. Especially in earthquake-prone areas, vibro-shock gravel pile reinforcement technology has become the preferred technology for designers because of its anti-liquefaction and outstanding seismic performance of the formed composite foundation. [0003] In essence, the vibroflotation method uses water with higher pressure in the sand, gravel, and soil layers, and sometimes pebbles or gravel are added for replacement. Therefore, the hole is always in a state of...
