Summary of the invention
The objective of the invention is at above-mentioned existing problems, a kind of control method of foundation settlement is provided, adopt this method that Based Intelligent Control is carried out in foundation settlement, thereby the effectively sedimentation on control basis, improve the bearing capacity and the stability on basis, this control method device is simple, can realize automatic intelligent control, and economic benefit is obvious.
Technical scheme of the present invention is:
A kind of foundational system of controlled sedimentation comprises basic component, utricule and control device, and described basic component is made of top cover and sidewall, is the hollow structure of sealing, bottom opening; Top cover is circle or regular polygon, and the diameter of top cover is not less than 20m, and the ratio of the diameter of top cover or maximal phase intersection and sidewall height is not less than 3, and the material of basic component is steel or concrete; Described utricule is made by deformably resilient material, the area that in the utricule when anhydrous is bluff body and utricule is identical with basic top cover base area, need bear at least 1 atmospheric pressure when charging into water in the utricule, utricule is provided with perforate and is connected with valve more than being arranged at top cover by pipeline, be provided with displacement transducer and pressure sensor in the utricule and be connected the interior every 10m of utricule by lead with control device more than being arranged at the water surface respectively
2Scope is provided with a displacement transducer and a pressure sensor at least, and utricule is provided with hook and is connected with the top cover bottom surface of basic component.
The deformably resilient material of described preparation utricule is a rubber.
Described utricule adopts and divides chamber structure, has been equipped with displacement transducer and pressure sensor in each branch storehouse.
Working programme of the present invention:
By the hook that is provided with on the utricule utricule is connected with basic top cover bottom surface, before foundation construction, installs, during construction with the basis installation in position.After the leveling of basic component installation in position, when the ground sedimentation Once you begin takes place, displacement transducer in the utricule between basis top cover and the ground begins induction, thereby open valve by control device and begin the deformed area that in utricule water filling is full of ground, when less than the pressure sensor preset pressure, come supercharging by water filling, when the volume of water filling is identical with settlement of foundation, after displacement transducer in the utricule is sensed basis recovery leveling state, stop water filling by the control device valve-off, the sedimentation of so implementing the monitoring ground changes, fully the levelness on control basis.
Advantage of the present invention is: by the utricule structure between ground and the basic top cover, use the utricule of water filling to replace the distortion of ground, thereby basic levelness and stability have been guaranteed, this device is realized automation by 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.This method is applicable to the control method of the foundation settlement in building, harbour, ocean, water conservancy and the bridge engineering.
The specific embodiment
Embodiment:
A kind of foundational system of controlled sedimentation comprises basic component 1, utricule 2 and control device 3, and described basic component 1 is made of top cover 4 and sidewall 5, is the hollow structure of sealing, bottom opening; Top cover 4 is circle or regular polygon, and the diameter of top cover 4 is 30m, and the height of sidewall 5 is 6m, and the material of basic component 1 is a concrete; Described utricule 2 is made by deformably resilient material rubber, the area that in the utricule 2 when anhydrous is bluff body and utricule is identical with basic top cover 4 base areas, need bear 1 atmospheric pressure when charging into water in the utricule 2, utricule 2 is provided with perforate 6 and is connected with valve 8 more than being arranged at the water surface by pipeline 7, be provided with in the utricule 2 displacement transducer 9 and pressure sensor 10 and respectively by lead be arranged at the control device 3 of top cover more than 4 and be connected utricule 2 interior every 10m
2Scope is provided with a displacement transducer 9 and a pressure sensor 10 at least, and utricule 2 is provided with hook 12 and is connected with the top cover bottom surface of basic component.
Among this embodiment, displacement transducer adopts journey displacement transducer PTR series in a small amount, and pressure sensor adopts high-accuracy general pressure sensor MD-G series, and control system realizes by the protel design platform.This foundational system uses equipment simple, and easy construction, economic benefit are obvious, and the integration engineering cost is low, is applicable to the control method of the foundation settlement in building, harbour, ocean, water conservancy and the bridge engineering.
