Abstract
Telescopic settlement monitoring point device belongs to engineering monitoring field, but the monitoring that the wide application is subsided in all kinds of engineering earth's surface / roads such as foundation ditch, track traffic, tunnels. Its characterized in that: the device includes settlement monitoring point and sleeve, blanking bar top cap steel pipe during the sleeve adopts, and the top cap can be started, places the sleeve center in the settlement monitoring point in. The original state soil layer can't reflect strictly according to the facts that the vertical bit on earth's surface moves less than just there's not enough time in order to avoid the monitoring point degree of depth, the utility model provides a telescopic settlement monitoring point device, the utility model discloses an accuracy of device from monitoring, convenience of operating and the principle that does benefit to the protection are set out, the road surface structural layer has been considered, freeze the thickness of the layer, the dark superstructure layer of design sleeve, monitoring point frozen soil layer super deeply, and design to carry drawing and prevent pressing dustproof top cap, can avoid the monitoring point to receive the influence of seasonal freeze thawing factor and other non - construction factors, the deformation law that can reflect shallow layer original state soil strictly according to the facts, but wide application in all kinds of engineering earth's surfaces, the settlement monitoring of road.
Description
Technical field
This telescopic settlement monitoring point device, affiliated engineering monitoring field, can be widely applied to the monitoring of all kinds of engineering earth's surface/road settlements such as foundation ditch, track traffic, tunnel.
Background technology
Surface subsidence monitoring is often used for embodying the engineering construction impact on surrounding formations, comparatively generally identify as monitoring with shallow-layer ground nail at present, there is certain limitation in this mark, owing to monitoring site is in top layer, ground, it is only capable of representing surface settlement, top layer is road surface structare layer, different from undisturbed soil character, and top layer, ground is often rolled by road vehicles and dynamic load repeatedly affects, and within the scope of frozen soil layer, affected significantly by Seasonal Freeze-thaw Soils, therefore below ground is often had cavity to occur but Monitoring Data does not have and embodies or embody situation about relatively lagging behind and occur, therefore the data monitoring acquisition can not well represent the vertical displacement of the top layer certain depth below caused by engineering construction, assay engineering construction is caused certain impact to the security risk that surrounding enviroment are brought.
Summary of the invention
For installing of further specification surface subsidence monitoring point, obtain the impact of Construction on Ground more accurately, this utility model patent provides telescopic settlement monitoring point device, outer sleeve can avoid its interior monitoring point by the interference of ground environment as far as possible, flip sleeve can cover with intact recovery road surface again after testing completes, it is to avoid affects evenness of road surface.
Telescopic settlement monitoring point device, it is characterised in that:
This device includes settlement monitoring point and sleeve thereof, and sleeve adopts hollow belt top cover steel pipe, and top cover can start, and settlement monitoring point is built in bushing core.
Further, top cover is connected by the component that can upwards lift with stack shell, this component is made up of the hollow cylinder fixing with sleeve stack shell and the round bar fixing with top cover, hollow cylinder is enclosed within outside round bar, round bar top and top cover are fixed, and round bar bottom is the diameter dimension cup dolly more than hollow cylinder internal diameter.
Round bar bottom is slightly larger than hollow cylinder internal diameter, and to avoid round bar to depart from from hollow cylinder, top cover separates with sleeve. Disclose built-in settlement monitoring point when top cover starts, maintain an equal level with its surrounding ground when top cover covers.
Further, tamp with sandstone between sleeve and settlement monitoring point, to keep stablizing of sleeve and settlement monitoring point.
Further, settlement monitoring point, top is fabricated to spherical, and bottom is fabricated to taper.
Further, length sleeve should at least over road surface structare layer, internal diameter 13��14cm, length 70��80cm.
Further, described settlement monitoring point is the screw-thread steel of diameter 20��32mm, and length is not less than 1m, exceedes road surface structare layer and the maximum frozen soil line at least 20cm in this area.
This device sleeve and the monitoring point degree of depth are reasonable, and sleeve cap is closed, and is provided with lip block, dust-proof, against pressure, be easy to operation, be beneficial to protection during monitoring.

Detailed description of the invention
This utility model device detailed description of the invention is sketched as follows: determines settlement monitoring point 1 depth of burying according to monitoring requirements, punches according to the depth of burying, sleeve 2 is put into hole and tamps; Settlement monitoring point identification (screw-thread steel) being placed on bushing core position, its hoop is maintained erectility, the depth of burying is squeezed in hammering subsequently, and in sleeve, sandstone backfill is closely knit.
