Description
Technical field
The present invention relates to a kind of adjustable superhigh pressure water jet device for pressure measurement.
Background technique
Just in high speed development, the mankind are turned to by exploring land exploitation land resources for dredging work and ocean engineering in recent years
Utilization and exploitation to marine resources.During developing ocean and construction ocean, the ground such as weak rock or hard soil are frequently encountered
Base.When the ground of the type uses traditional trailing suction hopper dredger operation, often inefficiency, is not easy to be mined.
In dredging work, hard soil belongs to the soil body type for being difficult to excavate, and requires drag head stock-removing efficiency high.Its
In, rake teeth drag size plays the role of with drag head equipped with the ability of breaking ground of high-pressure flush directly related.It is general to inhale ship for domestic rake at present
All over the high-pressure jet pressure that uses only 1-2MPa (10kg), be suitable for loose soil property, when encounter smaller infiltration coefficient cohesive soil,
When hard soil, knotts clay, since the shear strength of soil property is high, the effect of high-pressure jet is substantially reduced, and leads to rake teeth
Cutting depth deficiency and resistance increase, dredging efficiency is low.
The superhigh pressure water jet of different pressures can cut to rake teeth and provide enough cutting pressures, cut hard soil to rake teeth
Shi Jinhang precuts effect in advance, can greatly improve rake teeth stock-removing efficiency.Studies have shown that when high-pressure jet pressure is increased to
When 10MPa even 100MPa or more, superhigh pressure water jet can be become, coal mining, oil drilling, marble is can be applied to and cut
It cuts, the fields such as metal cutting.International large size dredging company also has firmly viscous using 38MPa high-pressure jet auxiliary raking, sucking mud digging ship dredging
The precedent of soil and rock, and create good benefit.
The requirement developed with excavation to excavating equipment in ocean engineering, as the mankind march to ocean, to ocean
It is higher and higher, therefore superhigh pressure water jet is studied, the present invention can provide a kind of superelevation injection measurement side of adjustable pressure
Method and device can be used for the characteristic of measuring study movement and static superhigh pressure water jet, can be developed and be developed based on this and is advanced
Drag head and rake teeth have broad prospects in dredging research field.Meanwhile the development of adjustable superhigh pressure water jet equipment, it can be with
Premise and basis is provided for hard soil cutting test, hard soil mechanism study is cut for subsequent development superhigh pressure water jet equipment and provides
Reliable super-pressure source.
In conclusion the superhigh pressure water jet measurement experiment device of the pressure adjustable can be special for dredging work mesohigh jet stream
Property and the mechanism study of jet stream cutting hard soil experimental basis and premise are provided, relevant test point can be completed in laboratory
Analysis and research, excavation and dredging for hard soil are provided fundamental basis and technical support, in dredging research field and ocean development
It has broad application prospects in field.
