Abstract
The utility model provides diaphragm wall top, a kind of subway station horizontal displacement monitoring forced centering observation device, comprise concreting pier and be arranged on the prism head above concreting pier, concreting pier is connected by telescopic connection bar with prism head.Described telescopic connection bar comprises the nut be arranged on concreting pier and the rotary screw be arranged in nut.What the utility model mainly improved forced centering pier sights screw-rod structure, the connector connecting top prism is improved, make a kind of telescopic connector, the complex environment of metro station construction can well be overcome like this, monitoring point is Height Adjustable, is improved, can reduces and change station number of times for monitoring point, single station intervisibility, reduce error, improve the stability detecting data.
Description
Technical field
The utility model relates to a kind of horizontal displacement monitoring forced centering observation device, particularly diaphragm wall top, a kind of subway station horizontal displacement monitoring forced centering observation device.
Background technology
Because metro station construction is complicated, site condition limits, and monitoring accuracy requires high, and traditional horizontal shift monitoring method of layouting implements and acquires a certain degree of difficulty, so need a kind of observation station distribution method that can be applicable to multiple complicated subway construction environment.
Summary of the invention
The utility model overcomes conventional flat displacement to layout the deficiency of monitoring method, and provide diaphragm wall top, a kind of subway station horizontal displacement monitoring forced centering observation device, this apparatus structure is simple, easy to operate.
The technical solution adopted in the utility model: diaphragm wall top, a kind of subway station horizontal displacement monitoring forced centering observation device, comprise concreting pier and be arranged on the prism head above concreting pier, concreting pier is connected by telescopic connection bar with prism head.
As preferably, described telescopic connection bar comprises the nut be arranged on concreting pier and the rotary screw be arranged in nut.
As preferably, described rotary screw has threaded hole, and threaded hole is provided with little rotary screw.
What this real Novel main will improve forced centering pier sights screw-rod structure, the connector connecting top prism is improved, make a kind of telescopic connector, the complex environment of metro station construction can well be overcome like this, monitoring point is Height Adjustable, is improved, can reduces and change station number of times for monitoring point, single station intervisibility, reduce error, improve the stability detecting data.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of telescopic connection bar.
Embodiment
As depicted in figs. 1 and 2, a kind of diaphragm wall top, subway station horizontal displacement monitoring forced centering observation device, comprise concreting pier 1, concreting pier 1 is provided with nut 2, rotary screw 3 is installed in nut 2, rotary screw 3 has threaded hole, and threaded hole is provided with little rotary screw 5, and little rotary screw 5 is provided with prism head 4.Certainly as required, in little rotary screw 5, less rotary screw can also be installed, by that analogy, all belong to protection domain of the present utility model.
