Abstract
The utility model discloses an it lays and measuring device to optimize foundation ditch monitoring point, including steel sleeve, bearing sheet, reflection of light piece and level measurement station, wherein steel sleeve places on bearing sheet, fixes steel sleeve and bearing sheet together on guan liang with the inflation screw, and reflection of light piece pastes on steel sleeve to the position at total powerstation place is aimed at to cross wire on the reflection of light piece, and the level measurement station is established at the steel sleeve top, is used for horizontal displacement prison time measuring to place indium tile chi. Beneficial effect: convenient operation to can optimize horizontal displacement and lay the vertical displacement monitoring point, no longer need place the prism carrying out horizontal displacement prison time measuring, has avoided increaseing and then improving horizontal displacement and monitor the precision because of laying the measuring error that the prism caused, can also practice thrift the manpower. The used material price of this device also than lower and repeatedly usable, reduces the monitoring point to lay the cost, and the relative energy -saving environmental protection still can be used with measuring instrument (surveyor's level and total powerstation) commonly used at present is supporting simultaneously.
Description
Technical field
This utility model is related to a kind of device of measurement, the dress that more particularly to a kind of optimization pit retaining monitoring point is laid and measured
Put.
Background technology
At present, with the fast development of Chinese Urbanization, deep-foundation pit engineering is more and more, but at many deep-foundation pit engineerings
In building dense area, excavation of foundation pit causes the generation of very big impact, pit failure to cause huge to surrounding enviroment
Loss, thus the monitoring of deep-foundation pit engineering is more and more important.
Foundation ditch vertical displacement and horizontal displacement monitoring point are usually directly arranged at enclosure wall using the nail of the survey with crosshair
Top or slope top.Vertical displacement observation is relatively more accurate when this method is observed, but due to surveying per secondary during horizontal displacement observation
Nail on placement prism, cause due to the angle difference towards total powerstation of each prism placement location and prism cause measure away from
Walk-off angle degree error increases.In order to solve this problem, the side of prism forced centering can be adopted during current horizontal displacement observation
Method improves precision, and so generally requires separately to lay vertical displacement and horizontal displacement observation point, and horizontal displacement observation
In need someone specially go place prism, waste of manpower.The point position of laying is more more in practical work process also more easily suffers
Destruction, while can also increase laying and monitor point protection cost.
The content of the invention
The purpose of this utility model be in order to solve current deep basal pit horizontal displacement and vertical displacement layout of the monitoring points in
Various not enough and device that a kind of optimization pit retaining monitoring point that provide is laid and measured.
The optimization pit retaining monitoring point that this utility model is provided is laid and the device that measures includes steel bushing, bearing sheet, anti-
Mating plate and level, wherein steel bushing are placed on bearing sheet, are together fixed on steel bushing and bearing sheet with setscrew
In Guan Liang, reflecting piece is attached on steel bushing, and the position that the crosshair alignment total powerstation in reflecting piece is located, and level sets
At the top of steel bushing, for placing indium watt chi during horizontal displacement monitoring.
Setting principle of the present utility model：
When monitoring point is arranged, first punch in Guan Liang, place setscrew, then with it by bearing sheet and steel bushing and hat
Beam connects into an entirety, then sets up total powerstation on datum mark or operating point, by total powerstation alignment lenses steel bushing,
Reflecting piece is pasted on steel bushing, the crosshair for making reflecting piece faces total powerstation.When carrying out vertical displacement observation using level gauge,
Indium watt chi is positioned on the level at the top of steel bushing every time.It is right every time when carrying out horizontal displacement observation using total powerstation
Quasi- reflecting piece is measured, and then is reduced every time because placing the personal error that prism is caused, and improves certainty of measurement.
The beneficial effects of the utility model：
This apparatus structure is simple, easy to operate, and energy optimum level displacement and vertical displacement layout of the monitoring points, is carrying out
No longer need to place prism during horizontal displacement monitoring, it is to avoid the measurement error caused because laying prism is increased and then improved the standard
Displacement monitoring precision, additionally it is possible to save manpower.This device material therefor price also than relatively low and reusable, reduces monitoring point
Deployment cost, relative energy-saving environmental protection, while can also support the use with measuring instrument (level gauge and total powerstation) conventional at present.

Specific embodiment
Refer to shown in Fig. 1 and Fig. 2：
The optimization pit retaining monitoring point that this utility model is provided is laid and the device that measures include steel bushing 1, bearing sheet 2,
Reflecting piece 3 and level 4, wherein steel bushing 1 are placed on bearing sheet 2, with setscrew 5 by steel bushing 1 and bearing sheet 2 one
Rise and be fixed in Guan Liang 6, reflecting piece 3 is attached on steel bushing 1, and the position that the crosshair alignment total powerstation in reflecting piece 3 is located
Put, level 4 is located at the top of steel bushing 1, for placing indium watt chi during horizontal displacement monitoring.
Setting principle of the present utility model：
When monitoring point is arranged, first punch in Guan Liang 6, place setscrew 5, then with it by bearing sheet 2 and steel bushing 1
An entirety is connected into Guan Liang 6, then total powerstation is set up on datum mark or operating point, by total powerstation alignment lenses steel
Sleeve 1, pastes reflecting piece 3 on steel bushing 1, and the crosshair for making reflecting piece 3 faces total powerstation.Vertical position is carried out using level gauge
When moving observation, indium watt chi is positioned on the level 4 at the top of steel bushing 1 every time.Horizontal displacement sight is carried out using total powerstation
During survey, every time alignment reflecting piece 3 is measured, and then is reduced every time because placing the personal error that prism is caused, and improves measurement essence
Degree.
