BVEM Bottom Feed Vibroflot Walking Pile Frame Type used for silt clay soft soil improvement

Vibro-bottom feed is an extension application of tranditional vibroflotation to expand the applicable range of vibroflotation technology.

A special vibroflotation method which can realize the filling material direct reaching at the real-time borehole bottom position of pile making through the feeding pipe attached to the vibroflotation equipment, and carries out the stone column or sand pile making.

Development of Bottom Feed Vibroflotation:

1. Entend the applicable scope of vibroflotation,can be used for silt soil improvement, offshore construction,dry method construction and project that require accurately control diameter

2. According to condition, customized equipment can be realized to execute construction under different situation

3. Whole process construction data record and automatic construction can be realized

4. Facilitate to reduce the waste of stone and carry out environmental and green construction

5. Dry, water and linkage of air&water method can be realized

6. Can realize pulverized stone coumn construction

Bottom feed vibroflot walking pile frame type

Structure profile

The main structure of walking pile frame type bottom feed vibroflot system:

1. BJZC-BFS-400-180 vibrator with double locked air-pressure cavities designed.

2. ZB200 walking pile frame supporting host with 38m column

3. Tracking hopper with spout

4. The whole process construction quality automatic control system

Characteristic

1. Double locked air-pressure cavities:

As show in picture 2, the position signal of the double lock pressure cavity reflected by the sensor to indicate the upper chamber door and the lower chamber door open and close alternately,a certain air pressure is always maintained in the blanking pipeline to ensure the rapid falling of stones.

In offshore area construction, it can effectively avoid outer water pouring into the pipeline or even flowing back to the cavity. This system equipment is widely used in projects with large pile depth or underwater vibroflotation stone column projects.

2. Walking pile frame:

The base frame can not only move around and rotate 360 degrees with the vibrator, but also move all construction equipment (air compressor, air storage tank, generator, control cabinet, etc.) on one platform as a whole, so as to realize large-area piling per unit and avoid the time consumption of each construction auxiliary equipment moving with the pile. In large-scale land construction, it can effectively save time and cost and improve construction efficiency.

3. Tracking hopper with spout :

The rated bucket capacity of the lifting hopper is 1.2m3, and the internal slope is greater than the rest angle of the stone to ensure material filling smoothly. The material door controlled by air cylinder can realize the sequential opening of hopper door and blanking chute.

It is attached to the track and slides up and down under the action of auxiliary winch lifting steel wire rope, making the whole feeding and conveying process more stable, convenient and efficient.

4. Automatic construction data recording management system:

It can realize the remote control function of multi equipment such as vibrator start and stop, pile quality parameter setting, feeding and valves. During construction, various construction parameters including the amount of filler will be recorded in real time to realize the whole process monitoring, control the construction process and ensure accurate construction.

Application and construction efficiency

The product has been successfully applied to the land construction of the bottom packing vibroflotation construction project of the new container terminal in Tiba Bay, East Timor. The total number of gravel piles is about 37000. The pile depth range is 15 ~ 21 m, the average hole making time is 15 ~ 25 min, the encryption time is 30 ~ 35 min, the working time of the whole pile is 50 ~ 70 min, and the maximum penetration SPT value is more than 50 blows.
