Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vibroflotation construction, more specifically, relates to a vibroflotation stone column construction parameter control system. BACKGROUND

[0002] Vibroflotation method is also called vibration water flushing method, which is a ground improvement method developed based on the principle that sand ground can be compacted by adding water and vibration, and later used for setting vibroflotation replacement stone column in clay layer. Vibroflotation method is one of the effective ground treatment methods widely used at home and abroad, which can improve ground bearing capacity, reduce building ground settlement, improve stability of earth and rockfill dam body and ground, and eliminate ground liquefaction. It is widely used in industrial and civil construction engineering fields. Conventional vibroflotation pile construction uses hard materials such as gravel, pebble and gravel with mud content not more than 5%, and particle size of about 20-150mm according to design requirements. Gravel feeding needs to be poured into pile hole on site by loader according to vibration condition.

[0003] Vibroflotation stone column refers to a pile body composed of stone in ground by using vibroflotation construction technology. The pile and original ground soil together form composite ground to improve ground bearing capacity. Vibroflotation stone column is a composite ground, which does not have obvious drainage consolidation and compaction effect on soil between piles. It is through replacement of original ground soil by stone column to make stone body play a role of reinforcement in original ground soil. The rigidity of pile body is greater than that of surrounding soil, so that ground stress is concentrated on stone column to reduce additional stress on soil around pile, improve bearing capacity of entire composite ground, and reduce compressibility. When ground treatment is performed by using this technology, construction quality directly determines the treatment effect of composite ground. Considering various construction procedures, the key procedure affecting construction quality is filling and vibration compaction after hole making, which mainly fills and vibration compacts gravel in compaction section length to meet various construction parameters required by design to ensure construction quality and ground treatment effect.

[0004] In the pile making stage, specific construction parameters such as pile making voltage, current, water pressure, vibration time and compaction section length are required to achieve the expected treatment effect. In conventional construction, it is relatively difficult to control vibration compaction current and vibration time, but these two parameters are key parameters of the technology, which requires vibration compaction in the compaction section length, and the duration after meeting the vibration compaction current meets the vibration time. However, in conventional operation of the prior art, the ammeter is installed in the control cabinet, and the equipment operator is often far away from the control cabinet, and also needs to control the time parameter. After the current information is transmitted to the equipment operator, the time parameter is measured, and the next construction is performed after meeting the requirement. The information transmission path is long, which is not conducive to construction quality control, and wastes time and human resources, which is not conducive to cost saving and speeding up construction progress.
