Description
Technical field
It is especially a kind of to be used for High aititude the present invention relates to a kind of TBM execution conditions detecting earth stress of lower all the period of time system
TBM execution conditions detecting earth stress of the lower all the period of time systems in regional geology stress test field.
Background technology
Since 21st century, the industry such as traffic, water conservancy and hydropower and energy is rapidly developed, and the mankind live in the earth's crust
Constantly extension and the extension of the breadth and depth in dynamic space, particularly in the last few years China in high slope, high-ground stress, buried length
The topography and geomorphology such as tunnel complex area, has built numerous Geotechnical Engineerings.Existing increasing number is it was demonstrated that earth's surface and underground work
The rock excavation that journey construction period is carried out tends to cause a series of deformations associated with stress release and breakoff phenomenon, this
With regard to needs, Stress Field Distribution rule has sufficient understanding over the ground, and the research most direct approach of the stress field regularity of distribution is exactly to carry out
Detecting earth stress, but in recent years, the deep and long tunnels of some complicated geographical reliefs use tunneling boring tunnel piercing more when excavating
Machine (TBM) is constructed, and during TBM normal operations, can not ensure have enough spaces to carry out detecting earth stress, therefore prior art
Detecting earth stress only could be carried out in TBM idle periods, and the time shared by TBM operations is longer, therefore use
The detecting earth stress system of prior art greatly reduces operating efficiency, have impact on construction speed.
The content of the invention
The technical problems to be solved by the invention be to provide one kind can under TBM execution conditions all the period of time carry out crustal stress
Test, and overall quick mobile, convenient and swift, time saving and energy saving test system can be realized.
The present invention solves TBM execution conditions detecting earth stress of lower all the period of time systems used by its technical problem, including wind
Band, test platform, jack up unit, transport vehicle, test equipment, fixture, the test platform include table top and are arranged on table top
The support frame of lower section, the transport vehicle are located at below table top, and the test equipment is fixed on the table top of test platform, the survey
Equipment and table top are tried between transport vehicle and wind band, the fixture is fixedly connected with test platform, the jack up unit
Lower end is fixed on transport vehicle, and the fixture is located at the top of jack up unit.
It is further to be provided with bolster between the fixture and jack up unit.
It is further that the bolster is sleeper.
It is further that the jack up unit is jack.
The beneficial effects of the invention are as follows：TBM execution conditions detecting earth stress of the lower all the period of time systems of the application set test
Standby and table top is arranged between transport vehicle and wind band, so as to the ingenious region for avoiding TBM constructions.Applied using the TBM of the application
All the period of time, detecting earth stress system did not interfered with TBM normal construction under the conditions of work so that detecting earth stress and TBM constructions can be with
Carry out simultaneously, so all periods can be made all to be fully used, the period without avoiding TBM constructions, realize complete
The target of period detecting earth stress, the duration can be thus greatlyd save, significantly improve production efficiency, accelerating construction progress.When
Installation test request can utilize the jack up unit on transport vehicle will be fixed when needing to carry the test equipment of the application
Upper test platform is increased to certain altitude fixed, the support frame of test platform is departed from supporting plane, then utilizes fortune
Defeated car, test platform and test equipment are transported into specified location.After test platform reaches specified location, jack up unit allows
Test platform, which declines certain altitude, to be made, support frame fall on the supporting plane in tunnel formed to after the secure support of test system just
Test job of the test equipment to crustal stress can be started.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Parts, position and numbering in figure：It is wind band 1, test platform 2, jack up unit 3, transport vehicle 4, test equipment 5, solid
Determine part 6, sleeper 7, support frame 8.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, TBM execution conditions detecting earth stress of the lower all the period of time systems of the present invention, including wind band 1, test are put down
Platform 2, jack up unit 3, transport vehicle 4, test equipment 5, fixture 6, the test platform 2 include table top and are arranged on below table top
Support frame 8, the transport vehicle 4 is located at below table top, and the test equipment 5 is fixed on the table top of test platform 2, the survey
Equipment 5 and table top are tried between transport vehicle 4 and wind band 1, the fixture 6 is fixedly connected with test platform 2, the raising dress
Put 3 lower end to be fixed on transport vehicle 4, the fixture 6 is located at the top of jack up unit 3.Under the TBM execution conditions of the application
Test equipment 5 and table top are arranged between transport vehicle 4 and wind band 1 by all the period of time detecting earth stress system, are avoided so as to ingenious
The region of TBM constructions.Therefore TBM normal construction has not been interfered with using all the period of time detecting earth stress system of the application, has been made
Obtaining detecting earth stress and TBM constructions can be carried out simultaneously, so all periods can be made all to be fully used, without keeping away
The period of TBM constructions is opened, the target of all the period of time detecting earth stress is realized, can thus greatly save the duration, significantly improve
Production efficiency, accelerating construction progress.It can be utilized when installing test request and needing and the test equipment 5 of the application is carried
Jack up unit 3 on transport vehicle 4 will be fixed on to fix is increased to certain altitude by upper test platform 2, makes the branch of test platform 2
