Description
Technical field
The present invention relates to the support technology field of excavation of foundation pit building enclosure form in dredging silt soil district.
Background technology
In the last few years, the dredging silt in shallow lake or bay used generally as land-based area backfilling material, enterprising at mud
Row construction also becomes a kind of trend of building.Along with excavation of foundation pit area and the degree of depth of silt soil region are increasing,
Its excavation is the biggest on the impact of surrounding, and excavation of foundation pit design and analysis transfers deformation control to from strength control design
Set up meter.For controlling foundation pit deformation, the general classification of traditional campshed supporting has a supporting, pile-anchor retaining, stake to add level
Support supporting etc..
Stake supporting is used in the shallow base pit engineering of muck soil in early days, but along with the excavation of foundation pit degree of depth increases, simple stake
The deformation effect that supporting controls foundation ditch is bad, the general deformation being used in combination control foundation ditch with anchor pole and horizontal support.Piled anchor
Supporting is distributed around " life line " engineerings such as intensive underground utilities due to excavation pit and is restricted use.Stake adds
Horizontal support supporting is big due to excavation of foundation pit area, longer dimension, supports self compression bigger so that the change of building enclosure
Shape can not get well controlling, and also brings the increase of cost to be restricted use simultaneously.These support patterns can not lead to
Crossing and monitor in real time respective deformation to be automatically adjusted self suffered power to control the deformation of foundation ditch, this is for the supporting of foundation ditch
Effect is disadvantageous.
Publication date is on November 19th, 2014, Publication No. CN104153374A, invention entitled " a kind of with tiltedly
Support with draw the combination type foundation pit supporting construction of anchor " Chinese invention patent application disclose a kind of foundation pit supporting construction, it sets
Have enclosure wall, tiltedly throw support, connect bearing, stiffening pile etc., it is simply that a kind of diagonal brace and the foundation pit supporting construction drawing anchor to combine.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency of the prior art, it is provided that a kind of novel intelligent deformation that has is adjusted
The foundation ditch curing system of energy-conservation power, can reduce support pile deformation, the outer skill such as ground settlement and foundation ditch bottom sludge protuberance of foundation ditch
Art problem.
To achieve these goals, present invention employs techniques below scheme: a kind of for dredging silt matter soil district foundation ditch
Can intelligent deformation regulation tiltedly throw support support system, it is characterised in that: include tiltedly throwing support supporting construction, data acquisition system

Whole foundation pit supporting construction stress trend is clear and can easily be accommodated the deformation controlling to make supporting construction holding safer
And stress.
As it is shown in figure 1, described data collecting system include being embedded in some first inclinometer pipes 107 at the outer earth's surface of foundation ditch,
Some second inclinometer pipes 108 of being embedded in support pile 102, it is embedded in the 3rd inclinometer pipe in dredging silt bottom foundation ditch
109, measure the outer ground settlement of foundation ditch, the deformation of support pile and the uplift capacity of foundation ditch bottom sludge respectively.Along foundation ditch other places
The different vertically degree of depth of table same plane position are embedded with multiple pore pressure meter 101, are used for measuring the outer mud different depth of foundation ditch
Under pore water pressure.There are at least three pieces of foil gauges 104 along the axis direction tiltedly throwing support at its surface mount, are used for measuring
Tiltedly throw the support deflection when excavation of foundation pit.
Mechanical control system includes a hydraulic jack 110, is connected with tiltedly throwing support 104, and Shi Hanzhang in advance.
Based Intelligent Control element 110 collects actually measured foundation ditch outer ground settlement, the deformation of support pile, foundation ditch bottom sludge
Uplift capacity, pore water pressure under the outer mud different depth of foundation ditch, tiltedly throw the monitoring of the support deflection when excavation of foundation pit
Data, and be analyzed with the result of calculation in design document, when Monitoring Data differs greatly with design calculation result
Time, Based Intelligent Control element controls described hydraulic jack 110 to tiltedly throwing support end Shi Hanzhang to prop up foundation ditch entirety
Protect and be stably adjusted, to meet the support action to foundation ditch, so can realize the real-time prison tiltedly throwing support supporting construction
Survey and regulate control in real time.
As shown in Figure 3, Figure 4, Based Intelligent Control element 110 collects actually measured foundation ditch outer ground settlement, support pile
Pore water pressure, oblique throwing support under deformation, the outer mud different depth of the uplift capacity of foundation ditch bottom sludge, foundation ditch are opened at foundation ditch
The Monitoring Data of deflection when digging, and be analyzed with the result of calculation in design document, when monitoring result and meter
Calculate result close to time, it is believed that supporting construction can ensure that base pit engineering is stable and safety, it is not necessary to is adjusted.
As shown in Fig. 5, Fig. 6, Fig. 7, Based Intelligent Control element 110 collects actually measured foundation ditch outer ground settlement, supporting
Pore water pressure, oblique throwing under the deformation of stake, the uplift capacity of foundation ditch bottom sludge, the outer mud different depth of foundation ditch are supportted at base
The Monitoring Data of the deflection during excavation of hole, and be analyzed with the result of calculation in design document, work as monitoring result
When differing bigger with result of calculation, data processing centre automatically controls hydraulic jack and carries out Stress control, improves supporting knot
The stress of structure, and the monitoring result after regulation is analyzed with result of calculation, when monitor value (bag after regulation simultaneously
Include the outer ground settlement of foundation ditch, support pile deformation, the mud uplift capacity bottom foundation ditch) close to the when of calculating safety value, can
To think that supporting construction can ensure that base pit engineering is stablized and safety, it is not necessary to be adjusted.
The present invention includes, but are not limited to above-described embodiment and content shown in the drawings, other all with the technical side of the present invention
Case has within the product structure of identical essentiality content each falls within protection scope of the present invention.
