Abstract
A kind of underground parking well construction with vibrating string type sensor and unidirectional RF chip is as existing Soft Deep Foundation Pit technology, all there is cement mixing pile as sealing and enclose curtain, cast-in-situ bored pile is as support pile, there is armored concrete interior wall on the inside of support pile, it is characterized in that, the vibrating string type sensor that outer soil body lateral stress is cheated in test is welded in support pile main reinforcement, and it is wired to the outer data collection processor of well, communication module is connect by conducting wire again, emit after into the communication module for being equipped with unidirectional RF chip, server is received at a distance downloads the detection system software, on computer screen, retrieve for examination the outer resistance to shear of soil change curve in hole, peak value exceeds software setting target, that is, early warning.Compared with prior art, resistance to shear of soil variation on the outside of civil engineering structure can be monitored by radio transmission, real time multi-human by having, once stress is more than warning data, timely early warning avoids cave-in accident.
Description
Technical field
The present invention relates to building field more particularly to a kind of underground parkings with vibrating string type sensor and unidirectional RF chip
Well construction.
Background technique
It is well known that there are many accidents in various regions architecture Foundation Pit Engineering, and mainly crater wall is collapsed since China reforms and opens up to the outside world
It collapses and jeopardizes periphery road or building.Sometimes single base pit engineering will cause tens million of first heavy losses.To find out its cause, being
Non- real-time dynamic monitoring cheats outer soil pressure variation.One field boundary heavy rain, level of ground water rise, and the mechanical property for cheating the outer soil body changes
Become, take reinforcement measure not in time, occurs until crater wall is collapsed.
Summary of the invention
The present invention provides a kind of underground parking well construction with vibrating string type sensor and unidirectional RF chip, can be on China edge
The municipal construction of extra large soft soil foundation and use, can allow more people many places pass through in time wirelessly, with computer or Real-time Monitoring with Mobile Telephone with
Early warning ensures the construction safety of parking well construction.
A kind of underground parking well construction with vibrating string type sensor and unidirectional RF chip of the present invention and existing soft clay area
Foundation pit technology is the same, all encloses curtain as sealing with the cement mixing pile for being more than cutting depth 5-10m, has more than cutting depth 8-
The cast-in-situ bored pile of 30m has armored concrete interior wall as support pile on the inside of support pile, which is characterized in that in support pile master
It is welded with test on muscle and cheats the vibrating string type sensor of outer soil body lateral stress, and is wired to the outer data collection processor of well,
The data-in port for connecing communication module by conducting wire again, into be equipped with unidirectional RF chip communication module after emit, at a distance
It receives server and downloads the detection system software, on computer screen, retrieve for examination the outer resistance to shear of soil change curve in hole, peak value exceeds
Software setting target, that is, early warning.Equally in the mobile phone-downloaded detection system software, monitoring chart can be equally found on mobile phone.
Vibrating string type sensor is made of vibratory string, permanent magnet, coil, clamping device and force mechanism.Vibratory string one end fixes,
One end is connected on pressure-sensitive diaphragm.
Unidirectional RF chip communication module then by unidirectional RF chip, grounding ports, power port, data-in port,
Data export antenna and shell composition.
Compared with prior art, the present invention the soil body on the outside of civil engineering structure can be monitored by radio transmission, real time multi-human by having
Stress variation, once stress is more than warning data, timely early warning avoids cave-in accident.

Gu waterstop (11)；
3. constructing 1.2m solid cement soil water-stop curtain (2) with mixing pile machine on the outside of support pile (4)；
4. in support pile (4) upper armored concrete capping beam (3)；
5. water filling dig capping beam (3) in the soil body, when construct the stage procedure, data collection processor (6) and unidirectionally
Radio frequency chip communication module (7) is connected with the mains, and monitoring system starts monitoring and cheats outer resistance to shear of soil variation, as long as monitoring personnel is in electricity
Brain server (26) or the mobile phone-downloaded monitoring system software, constantly more people's monitorings, until taking soil to shaft bottom absolute altitude, then underwater pouring
Plain concrete back cover layer (12).
6. drawing water in pit shaft after concrete sealing bottom layer (12) intensity reaches, by current art construction reinforced bar concrete bottom
