Description
Technical field
The present invention relates to a kind of seismic wave advanced prediction loading devices and method for double shield rock rippers.
Background technique
In recent years, with the rapid development of infrastructure construction in china, water conservancy and hydropower, traffic engineering, subway engineering, municipal administration
The fields such as engineering need excavate a large amount of subterranean tunnel (hole) engineering.TBM (rock tunnel(ling) machine) construction method is dug by feat of itself
Traditional drilling and blasting method is gradually replaced to become priority in China tunnel (hole) construction into the advantages that high-efficient, construction safety is high-quality
Highest construction method.Wherein, double-shielded TBM, during constructing tunnel (excavate, slag tap, lining cutting grouting etc. operations) realize
Cavitation efficiently uses tunnel space, and can be well solved massif tomography and wait the construction under Complicated Geologic Conditions to ask more
Topic.
But in face of the increasingly complex strata condition in west area (large-scale fault belt, fracture extension zone, flabbily
Layer, solution cavity, underground river) when, double-shielded TBM is easy to happen serious card machine, damages, scraps the even major accidents such as casualties.
Therefore, front geological condition is verified using forward probe method in double-shielded TBM environment in advance, and adjusts arrangement and method for construction in time
To evade dangerous situation, ensure that construction safety is particularly important.
TBM advanced prediction instrument and method have obtained preferable development in recent years, wherein seismic wave forward probe method with
Its farther away detection range and preferable interface recognition effect, have obtained more being widely applied.However, current TBM seismic wave
Advanced prediction instrument and method are designed for Open TBM mostly, and the use under double-shielded TBM environment exists certain tired
Difficulty embodies are as follows:
It has the following problems:
(1) dynamite source is larger to personnel and equipment risk, more demanding to dose control when impulsing, and transports to explosive
It is required with the safety guarantee during storage high；It is low to hammer focus the degree of automation, source level and a shake position cannot be accurate
Control, required space is big and influences site operation.Therefore, need propose it is a kind of applied to it is double-shielded TBM, safe and efficient, can
The high focus that impulses of recycling, mechanization degree.
(2) directly section of jurisdiction impulse and can generate damage to it, influence lining cutting effect, and may between section of jurisdiction and palisades
It does not fit closely, preferable detection data can not be obtained；And cutterhead is the critical component of double-shielded TBM equipment, structure
Complexity, its workability may be will affect by directly impulsing on cutterhead, reduced driving speed and efficiency, in turn resulted in economic damage
It loses.It would therefore be highly desirable to propose the rational position that a shock excitation device for being applied to double-shielded TBM is carried.
(3) wave detector arrangement is inflexible.The installation of wave detector needs to carry out the connection of transmission line and wave detector.Mesh
Preceding practices well be manually with drill bit on wall aperture lay wave detector, this method inefficiency, be easy influence TBM construct work
Phase.
Simultaneously as the construction of double-shielded TBM is increasingly complex compared to Open TBM and single shield TBM, including inside can
With space exploration is narrower, detection device is difficult to the disadvantages of directly contacting tunnel wall under the influence of lining segment, earthquake is given
Wave method advanced prediction brings very big difficulty.
1. being influenced by section of jurisdiction, existing method can not directly impulse to tunnel surrounding rock body, influence detection quality.Explosive
Focus is there are security risk and is easily damaged section of jurisdiction；Hammering focus can only be impulsed by tapping section of jurisdiction, and energy is weaker, and manages
Leakiness is contacted between piece and rock mass, there are stronger reflecting interface, seriously affect the quality that impulses, lead to not obtain preferable
Detection data.
2. lacking suitable for the wave detector automatic installation apparatus and method under the environment of section of jurisdiction.Common method is manually to exist at present
Wave detector, this method inefficiency are laid in aperture in lining cutting, and are easy to damage section of jurisdiction.
Therefore, during carrying out focus and detector position and selecting, it should consider the efficiency that impulses of focus, feasible swash
The automation for shaking position and wave detector is placed, and is taken into account again and is made full use of double-shielded TBM inner space and do not influence development machine
The factors such as tunneling construction.In a word, it would be highly desirable to propose a kind of for the advanced prediction instrument loading device carried in double-shielded TBM.
