Description
Technical field
The present invention relates to the well knots that stops between building field more particularly to a kind of underground deep space of long-range wired control construction
Structure.
Background technique
It is well known that city parking difficulty is the bottleneck of current city development, especially in Deposits in Eastern Coastal China soft soil foundation city
The parking difficulty in city is even more serious, in addition, many accidents occurred in various regions architecture Foundation Pit Engineering since reform and opening-up, has studied carefully its original
Because being to cheat outer soil pressure variation because of non-real-time dynamic monitoring.One field boundary heavy rain, level of ground water rise, and cheat the mechanical property hair of the outer soil body
It is raw to change, it finds and takes measures not in time, directly contribute the generation of foundation pit collapse accident.
Summary of the invention
The present invention provides the well construction that stops between the underground deep space of long-range wired control construction a kind of, can be in China coast weak soil
The municipal construction of ground and use, can be by acquiring the lateral stress data of the soil body on the outside of hole in the construction time in real time, and passes through number
Telecommunication point is converted into according to processor, and wired to be sent to terminal computer, monitoring personnel downloads the monitoring software on computer at a distance, just
Hole outside soil stress change curve can be observed in real time, and guiding construction guarantees sidewall safety.
Parking well construction and existing Soft Deep Foundation Pit skill between a kind of underground deep space of long-range wired control construction of the present invention
It is more than that the cement mixing pile of cutting depth 5-10m does sealing and encloses curtain that art is the same, which all to be had, has more than the brill of cutting depth 8-30m
Hole pouring pile has armored concrete interior wall as support pile on the inside of support pile, which is characterized in that on the outside of the support pile on reinforcing bar
It is welded with test and cheats the silicon fiml strain gauge transducer of outer soil body lateral stress, and be wired to the outer data collection processor of well,
The computer terminal of distant place is connected to by conducting wire again.Computer downloads the detection system software, just will appear hole on computer screen
Outer resistance to shear of soil change curve, peak value exceed setting target, that is, early warning.
It can resistance to shear of soil becomes on the outside of wired monitoring civil engineering structure at a distance in real time compared with prior art, the present invention having
Change, once stress is more than warning data early warning immediately, avoids the major accidents such as parking well construction collapsing.
Detailed description of the invention
Fig. 1 is parking well construction diagrammatic cross-section of the embodiment of the present invention.
Fig. 2 is silicon fiml strain gauge transducer structural schematic diagram of the embodiment of the present invention, a top view, b sectional view.
Drawing explanation: 1 ground concrete layer, 2 soil cement water-stop curtains, 3 capping beams, 4 support piles, 5 mine pits, 6 reinforcing bars are mixed
Solidifying soil interior wall, 7 data collection processors, 8 muds, 9 argillic horizons, 10 gravel layers, 11 soil cements reinforce waterstop, and 12 elements are mixed
Solidifying grave bottom, 13 reinforced concrete floors, 14 fixed metal weld tabs, 15 inductive reactances, 16 diaphragm sides, 17 varistors, 18
Thin silicon diaphragm, 19 titanium dioxide silicon wafers, 20 vacuum chambers, 21 borosilicic acid slides.
Specific embodiment
According to Fig. 1, parking well construction embodiment construction procedure is as follows between a kind of underground deep space of long-range wired control construction:
1. showing field boundary in underground parking well construction, support pile (4) of the first construction drill bored concrete pile as parking well construction is being cheated
At longitudinal main reinforcement lower end of well (5) surrounding pile body, middle part and the upward 3-6m in lower end, equipped with the 30-50 being distributed at a certain distance
The silicon fiml strain gauge transducer of a induction soil body lateral pressure, and sensor conductor is involved from the top of support pile (4) and is connected to data
Acquisition Processor (7), then data collection processor (7) is accessed into distant place computer terminal with conducting wire；
2. in mine pit (5) back cover absolute altitude following soil layer cement mixing pile machine or the cement of whirl spraying ram machine construction 5-10m thickness
Soil reinforces 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) top pouring armored concrete capping beam (3)；
5. grabbing the soil body that cone is dug in capping beam (3) to water filling in mine pit (5), and with punching, data collection processor (7) is connect
Upper power supply, monitoring system start monitoring and cheat outer resistance to shear of soil variation, and the elastic sensing element of silicon fiml sheet type sensor is solid for periphery
The thin silicon diaphragm (18) of deposit category weld tabs (14).It radial strain and is tangentially answered when thin silicon diaphragm (18) stress deformation, at center
Change reaches positive maximum value, and edge radial strain reaches negative maximum value, tangential strain zero.Separately strained with two
Titanium dioxide silicon wafer (19) is attached to respectively at positive and negative maximum strain, is connected into the half-bridge circuit of adjacent bridge arm to obtain larger sensitivity,
It is sealed in vacuum chamber (20) outer cover borosilicic acid slide (21).Strain data is processed into electric signal by data collection processor (7),
Terminal computer server is sent to by conducting wire, as long as monitoring personnel downloads the monitoring system software on host computer, is just reached
Resistance to shear of soil change curve avoids cheating once the super early warning line of curve, takes immediate steps on the outside of distant place wired monitoring mine pit (5)
Wall cave-in accident.Soil is taken to get shaft bottom absolute altitude, then underwater pouring plain concrete back cover layer (12).
6. drawing water in mine pit (5), after concrete sealing bottom layer (12) intensity reaches by current art construction reinforced bar concrete
Bottom plate (13)；
7. being segmented the armored concrete interior wall (6) that formwork pours 0.8-1m thickness from bottom to top by current art, that is, complete this
The construction of invention.
Claims (1)
1. stop well construction between a kind of underground deep space of long-range wired control construction, which is characterized in that the reinforcing bar on the outside of support pile
On be welded with test and cheat the silicon fiml strain gauge transducer of outer soil body lateral stress, and be wired to well data acquisition process outside
Device, then it is connected to by conducting wire the computer terminal of distant place.
