Description
Technical field
The utility model belongs to geotechnical engineering field, the more particularly to device of a kind of fixation pressure box outside pipe.
Background technology
Artificial stratum freeze-wellboring technology is that China's coal-mine pit shaft passes through that topsoil is thicker, the more strata condition in water-bearing layer
A kind of lower more satisfactory special sinking method.China from nineteen fifty-five open Luan First Weighting On Linxi Coal Mine west air shaft use for the first time construction freezing method with
Come, a shaft of vertical well more than 700 of having constructed, accumulative freezing shaft linear meter(lin.m.) reaches 150km, is widely used.Artificially
Layer freezing technology started from for 19th century, was based on the physico-mechanical properties research of frozen soil under the conditions of weather freezing, with artificial
What freezing sinking shaft gradually grew up.Artificial stratum freezing process is to utilize artificial cooling technology, and low temperature refrigerant is sent into stratum, is made
Water in stratum freezes, and natural ground is become frozen soil, increases its strength and stability, to resist presses and completely cuts off underground water
Contacting between excavation body, to carry out opening for tunnel, vertical shaft and underground engineering under the protection of closed continuous frozen soil wall
Dig and do a kind of special formation reinforcement means of permanent support.
Since the 21th century, in China, eastern region main mining area superficial part coal resources are almost exhausted, and coal mining is deep
Degree is increased with 20m/a speed, it is contemplated that 20 years futures, the mining depth of many coal mines will be up to 1000~1500m.In such depth
The effect for needing using frost wall as gib to consider very big lateral pressure in soil layer, needs very thick frost wall can
Meet engine request.In deep-well sinking operation work progress, since frost wall stability not enough causes after excavation, freeze
Tu Jing sides, which deform excessive phenomenon, can still occur, and serious security risk is brought to engineering.Some scholars think in frozen clay layer
In, it is the side pressure that only considered soil body dead weight when calculating and generate to calculate the reason of Frozen wall thickness is unsatisfactory for Practical Project requirement
Power and the frost heave for having ignored the soil body in frost wall forming process.Due to frost heave action so that the soil body on frost wall periphery is squeezed
And one displacement field of generation and stress field, this displacement field and stress field react on frost wall again so that frost wall is by one
The drag generated by soil deformation.This just increases the stress of frost wall on the basis of original strata pressure so that frost wall by
Power is excessive and then generates excessive deformation after excavating.
For the safety of guarantee Frozen Deep sinking shaft construction, the frost-heave force in freezing process is just must take into consideration, and is not had also currently
There is a kind of rationally effective vertical frost heave predicting means.In view of freezing soil by temperature field directly affected and temperature field survey
Trial work section is ripe, mostly uses temperature field greatly at this stage and calculates frozen soil to determine Frozen wall thickness and position, then by frozen-heave coefficient
Frost heaving amount, and then obtain frost heave displacement field and stress field.However the frost heave prediction technique use indirect means, can only approximation provide
Frost heave displacement field and stress field, related body frost heaving theory also need further perfect.
