Abstract
The invention is a cross vibrating wing, a cross vibrating wing for liquefied groundsill processing, relating to a form of vibrating wing selected when processing sandy soil and silt groundsills and other liquefied groundsills, and the vibrating wing is connected of two steel plates vertically intersecting and having through holes, the four straight wing sides of the vibrating wing are equipped with continuous convex semicircular teeth, the bottom end of the vibrating wing is equipped with needle teeth, and the through holes are uniformly distributed on the steel plates, and the steel plates are 2-5cm thick, and the length of the vibrating wing is determined according to the designed depth of liquefied groundsill processing. And the vibrating wing can improve the effect of soil resonance compacting construction.
Description
Technical field
The present invention is a kind of cross-shaped vibration wing that liquefied foundation is handled that is used for, the form of selected oscillating airfoil when relating to the working power densification process and handling liquefied foundation such as sand, silt.The technical field that belongs to the ground treating apparatus.
Background technology
China's Yangze river and Huai river river valley liquefied foundation that often distributes, under dynamic load functions such as earthquake, circulation, vehicle, foundation liquefaction is the principal mode of foundation failure, often causes the quality problems of speedway.Using maximum methods in the whole bag of tricks of process liquefaction ground is to increase soil body compactness.The form of liquefaction selected oscillating airfoil in handling will influence the effect of vibratory compaction greatly.Best closely knit effect should be able to reach the maximum delivered of energy.
Summary of the invention
Technical problem: the deficiency at existing vibratory compaction method construction equipment the purpose of this invention is to provide a kind of cross-shaped vibration wing that can improve effect of soil resonance compacting construction.
Technical scheme: cross-shaped vibration wing of the present invention connects into cross section by two steel plates that have through hole that intersect vertically soon and is criss-cross oscillating airfoil, and four straight wing limits of this oscillating airfoil are provided with continuous convex semicircle tooth, and the bottom of oscillating airfoil is provided with the spine tooth.The institute hole of opening evenly distributes on steel plate on this oscillating airfoil.Steel plate thickness is 2～5cm, and oscillating airfoil length is decided according to the liquefied foundation Treatment Design degree of depth.
Beneficial effect: compare with existing power foundation treatment technology, facility of the present invention have following advantage:
The present invention can satisfy the needs of different reinforcement depths; Save processing cost, present technique does not need filler in position to the liquefied foundation processing; The efficiency of construction height during construction, only needs heavy oscillating airfoil to get final product, and vibratory compaction gets final product when extracting; The closely knit effect of superficial part soil layer is strengthened, because vibration is the internal vibration of whole oscillating airfoil length range, the soil layer of superficial part is subjected to the historical influence of more vibration, and its intensity must improve, when meeting load and bearing mainly is the fact that influenced by the superficial part bearing stratum, can obviously reduce the ground differential settlement.The convex semi-circular design on circular hole that is provided with on the oscillating airfoil and wing limit has reduced the quality of oscillating airfoil, is beneficial to the dissipation of the pore water pressure that produces in the transmission of energy and the vibratory compaction process.

The specific embodiment
Cross-shaped vibration wing of the present invention is welded into cross section by two two block plates 2 that have through hole 1 that intersect vertically soon and is criss-cross oscillating airfoil, four straight wing limits of this oscillating airfoil are provided with continuous convex semicircle tooth 3, the profile of the bottom of oscillating airfoil is circular-arc, is provided with spine tooth 4 in the bottom.The institute hole of opening 1 evenly distributes on steel plate 2 on this oscillating airfoil.Steel plate 2 thickness are 2～5cm, and oscillating airfoil length is decided according to the liquefied foundation Treatment Design degree of depth.
This oscillating airfoil is connected under the hydraulic vibration driver, utilizes leading truck to construct.Selected hydraulic vibration driver be with hydraulic pressure as power, lift hammer body quick draining then, reverse fuel feeding descends hammer body fast simultaneously, the hammering pile cover sinks in the soil oscillating airfoil.Simultaneously, hydraulic hammer directly transmits pile body with energy by this buffer of pile cover, does not generally need a special folder stake device, therefore can be without restriction the steel sheet pile of different shape be carried out the pile sinking operation.In the selection of pile monkey, the minimum exciting force of guaranteeing vibrating hammer is greater than the moving frictional resistance of soil under vibrational state.During pile vibrosinking, enough amplitudes must be arranged, make the instantaneous whole elastic pressures of vibration force, and make the destructive power of stake end, can make stake impact soil shrinkage up and down greater than foundation soil greater than pile peripheral earth.The exciting force of vibrohammer is relevant with frequency, and frequency is high more, and exciting force is big more.Square being directly proportional of exciting force and frequency.High-frequency (100-150HZ) is applicable to hard clay soil layer, and intermediate frequency (20-60HZ) is used for loose shock ply and sand pile sinking, low frequency (15-20HZ), the main purpose that reaches pile sinking and pile pulling by forced vibration and soil resonance.The key of using the frequency modulation hydraulic vibration driver to carry out the closely knit construction of the soil body is to make shot soil body vibratory compaction certain hour extract oscillating airfoil then to resonance frequency frequency adjustment when arriving the handled degree of depth, reaches the purpose of the closely knit effect raising of the soil body.
