Multi-vibroflot resonance ground treatment equipment and method

Abstract

The invention discloses multi-vibroflot resonance ground treatment equipment and a multi-vibroflot resonance ground treatment method, and relates to the technical field of sandy soil ground treatment. The equipment comprises an equipment main body, a cantilever, a suspension cable component, channel steel, at least two steel ropes and vibration devices in a number which corresponds to that of the steel ropes, wherein the equipment main body is connected with the suspension cable component through the cantilever; the suspension cable component is fixedly connected with the middle position of the channel steel; the two sides of the channel steel are connected with the at least two uniformly distributed steel ropes; the lower parts of the steel ropes are fixedly connected with the corresponding vibration devices; the vibration devices are vibroflots in which skewed rotors driven by motors are arranged, and are provided with water inlets which are connected with a high-pressure water pump; and a buffering vibration-proof gasket is arranged between each vibration device and the corresponding steel rope. The construction method is simple, the equipment and the method are rational in design, convenient to implement, low in construction cost and high in working efficiency, can be effectively applied to a sandy soil ground treatment process, and have good treatment effects, and the construction quality is easily ensured.

Description

technical field [0001] The invention relates to the technical field of sandy soil foundation treatment, in particular to a multi-head vibrator resonance foundation treatment equipment and a method thereof. Background technique [0002] At present, the commonly used foundation treatment methods mainly include water fall sand replacement, dynamic compaction, cement mixing pile, lime-soil compaction pile, vibratory impact compaction method suitable for treating medium sand and coarse sand foundations with clay content not greater than 10%. Wait. However, the geology of the sandy soil foundation has the following characteristics: first, the upper part of the eolian sand is very loose, with low and uneven bearing capacity, and poor engineering performance; second, the sand clay content is small, and the cohesion between sand particles is poor. The void ratio is large and the water permeability is strong; the third is that the internal friction between the unsaturated sand partic...

Problems solved by technology

However, the geology of the sandy soil foundation has the following characteristics: first, the upper part of the eolian sand is very loose, with low and uneven bearing capacity, and poor engineering performance; second, the sand clay content is small and the cohesion between sand particles is poor. The void ratio is large and the water permeability is strong; the third is that the internal friction between the unsaturated sand particles is relatively large; the fourth is that the shallow groundwater is rich in reserves, etc.

Therefore, when the above-mentioned common foundation treatment methods are used to treat the sandy soil foundation, there are many problems such as high input cost, complicated construction technology, low construction efficiency, poor foundation reinforcement treatment effect, and unsuitability for deep foundation reinforcement. deficiencies and deficiencies

Therefore, the above-mentioned geological characteristics of the sandy soil foundation make all kinds of foundation treatment methods commonly used at present not fully applicable.
