Description
Technical field
The invention belongs to foundation construction technical fields more particularly to a kind of anchor jacked pile precharge pressure to seal piling method.
Background technique
It is anchored in original base currently, the prior art commonly used in the trade is such that anchor jacked pile refers to utilize
The counter-force that anchor pole provides implements piling, and jacked pile is generally small bore stake, is mainly used for the consolidation process on basis；If sealing stake processing
Bad to will lead to the inside and outside of stake and do not completely cut off completely, the inside of stake will receive the erosion of external factor, damage stake
Quality and service life, or even the structure of influence building are accurate.Existing anchor frame is fixed simply by the anchor pole of bottom end,
When pushing to jacked pile, it is be easy to cause loosening for bottom end anchor pole, causes the shaking of anchor frame.
The development of sensor technology brings great variety to people's lives.X ray sensor is exactly that one kind makes extensively
Sensor.The basic principle of X ray sensor is: when wave is propagated in a certain specific structure, disperse characteristic (i.e. wave number
Relationship between frequency) it is certain.When external physical quantity variation, such as temperature, electric field, magnetic field and architecture quality
It changes, this variation can change the variation of the propagation characteristic such as velocity of wave or frequency of wave, therefore, pass through the wave number and frequency of wave

In a matrix, p is from status transition probability of state, and r is to absorb probability of state, the following form of the relationship of p and r:
Fundamental matrix F:
F=(I-Q)-1
It is as follows to absorb matrix B:
B=FR=(I-Q)-1×R。
8. anchor jacked pile precharge pressure as described in claim 1 seals piling method, which is characterized in that determine and obtain corresponding standard
Really with the deflection probability of efficiency, construct transition state include accurately with efficiency quantizing rule and accurately with efficiency comparison rule.
