Background technology
At present, in harbour, ocean, water conservancy and bridge engineering, especially on mucky soil matter, the settlement issues of raft foundation is the main puzzlement that raft foundation is used.In the disadvantageous zone of this geological conditions, because the design feature of raft foundation is easy to produce the uneven subsidence on basis.
Summary of the invention
The present invention provides a kind of foundational system of controlled sedimentation for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of foundational system of controlled sedimentation; Comprise the basis; Said basis comprises top board; Said top board has the utricule that a deformably resilient material is processed, and is connected with water pipe on the said utricule, and said water pipe is provided with valve; Be provided with pressure sensor and displacement transducer in the said utricule, said pressure sensor is connected with the control system with said displacement transducer, and said valve is controlled by the control system.
The every 10m of said utricule
2A said displacement transducer and said pressure sensor are set in the scope at least.
Said utricule is connected through hook with said top board.
The pressure that said utricule can bear is at least 1 atmospheric pressure.
Said basis is a raft foundation, is formed with a plurality of minutes storehouses under the top board of said raft foundation, and each was provided with a said utricule in said minute in the storehouse.
Advantage and good effect that the present invention has are: through being employed in the structure that utricule is set between ground and the base roof plate, the distortion of ground is filled up with the utricule of water filling, thereby guaranteed basic levelness and stability; The present invention has realized automation through sensor and control system, can effectively increase the reliability on basis, thereby improve basic bearing capacity and stability; Foundation settlement control is remarkably productive; Use equipment is simple, and easy construction, economic benefit are obvious, and the integration engineering cost is low.The present invention is applicable to building, harbour, ocean, water conservancy and bridge engineering.
Description of drawings
Fig. 1 is an elevation of the present invention;

Fig. 3 is an operating principle sketch map of the present invention.
Among the figure: 1, raft foundation, 2, utricule, 3, pressure sensor, 4, displacement transducer, 5, wiring, 6, lead, 7, the control system, 8, valve, 9, water pipe, 10, ground generation settling zone, the zone that is full of after the 11. utricule water fillings.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of raft foundation system of controlled sedimentation mainly comprises raft foundation 1 and raft foundation utricule 2, and said utricule 2 is processed by rubber, and utricule 2 can bear the effect of highly pressurised liquid, generally can bear at least 1 atmospheric pressure.In each branch storehouse of raft foundation 1 utricule 2 all should be set; Utricule 2 is installed in the top board bottom in each branch storehouse of raft foundation 1 before raft foundation 1 construction; During construction with raft foundation 1 installation in position; Be utricule 2 between raft foundation 1 top board and ground, the floor space of 1 fen Hold Ceiling of the cross-sectional area of utricule 2 and raft foundation is identical in the application.Be connected with water pipe 9 on the utricule, water pipe 9 is provided with valve 8, and valve 8 is by 7 controls of control system.Pressure sensor 3 and displacement transducer 4 are installed in the utricule, and they are connected to control system 7 through lead 5,6.The every 10m of said utricule
2 A displacement transducer 4 and a pressure sensor 3 are set in the scope at least.
When the pressure in the utricule during, can add water and come supercharging less than preset pressure.Utricule is provided with hook, can utricule be connected with raft foundation top board bottom surface through hook.After the leveling of raft foundation installation in position; When the ground sedimentation Once you begin took place, the displacement transducer in the utricule was sensed the settling amount of ground, and control system control valve door is opened; Begin water filling in utricule; When the volume of water filling was identical with settlement of foundation, after pressure sensor in the utricule and displacement transducer were sensed raft foundation recovery leveling state, control system closing valve stopped water filling.Be plastic gonosome after the utricule water filling, can be full of all spaces automatically, if certain regional ground changes, thereby this utricule automatically water filling be full of the deformed area of ground.So the sedimentation of monitoring ground changes, and has controlled the levelness of raft foundation effectively.
See also Fig. 2 and Fig. 3; When ground somewhere generation differential settlement, the pressure sensors 3 in the utricule 2 between raft foundation 1 top board and the ground are sent to control system 7 with displacement transducers 4 with sensed data, and control system 7 opens valve 8 beginning water fillings; When the differential settlement amount of the volume of water filling and ground is identical; The zone 10 of ground generation sedimentation has been filled up in the zone 11 that is full of after the utricule water filling, and after the pressure sensor 3 in the utricule 2 was sensed raft foundation 1 recovery leveling state with displacement transducer 4, control system 7 beginning valve-offs 8 stopped water filling; The sedimentation of so implementing the monitoring ground changes, and controls the levelness of raft foundation fully.
The present invention fills up the distortion of ground through the utricule between ground and raft foundation top board with the utricule of water filling, thereby has guaranteed the levelness and the stability of raft foundation; Realize automation through pressure sensor, displacement transducer and control system, can effectively strengthen the reliability of raft foundation, thereby improve the bearing capacity and the stability of raft foundation; Foundation settlement control is remarkably productive; Use equipment is simple, and easy construction, economic benefit are obvious, and the integration engineering cost is low.The present invention is applicable to building, harbour, ocean, water conservancy and bridge engineering.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, for example; Raft foundation is by the gravity type foundation of band skirtboard or divide the bucket foundation of bucket foundation or many barrel structures in storehouse to replace the foundational system that forms, and these all belong within protection scope of the present invention.
