Pipe datum mark school geodesic structure.
Background technology
With the rapid development of China's hydropower, the safety of side slope is more and more important, in the design of its support of side slope, side
Definite the having very important significance of the potential slide surface in slope, it is a problem to also tend to.Clinograph is to determine side at present
The potential slide surface in slope is most effective, most common method, and inclinometer is mainly used to monitor the horizontal distortion of deep rock mass or the soil body, leads to
Crossing Monitoring Result can be with accurate judgement deep rock mass or the potential slip locations of the soil body.Inclinometer pipe operation principle is very simple, deviational survey
Pipe is typically mounted in through unstable soil layer to the vertical drilling on lower stabilizer stratum, using movable clinometer probe from deviational survey
The bottom of tube wall groove is moved to top, is suspended generally at half meter of spacing and is measured inclined work, and when calculating assumes
Point (or fixed point) on the basis of deviational survey bottom of the tube, by the displacement of gradient conversion horizontally (x to, y to), from bottom to
Top is added up successively can obtain the offset of inclinometer pipe, show the moving displacement that rock mass or the soil body are occurred.
It was found from inclinometer pipe operation principle, point (or fixed point) on the basis of deviational survey bottom of the tube is commonly assumed that, if early period
Work deficiency is surveyed, can causing the datum mark (or fixed point) of deviational survey bottom of the tube, that mobile or inclinometer pipe local deformation occurs is excessive and lead
Clinometer probe is caused to be unable to reach bottom, will not only make observing buoy distortion but also inclinometer pipe is substantially at the work shape scrapped
State, so as to can not accurate judgement deep rock mass or the soil body potential slide surface, be unfavorable for the safety and stability of side slope.Due to by various
The restriction of factor, presently relevant Specifications of Monitoring Technology, which is also not known, to be required.
Utility model content
The deficiencies of to overcome existing inclinometer pipe that may cause to observe achievement distortion due to basic point changes, the utility model
The technical problem to be solved is that：A kind of inclinometer pipe datum mark school for helping to improve inclinometer pipe measurement accuracy is provided and surveys knot
Structure.
Technical solution is used by the utility model solves its technical problem：
Inclinometer pipe datum mark school geodesic structure, including the inclinometer pipe being vertically arranged in slope soil, the inclinometer pipe is located at
The nozzle side on slope soil surface is equipped with observation pier, and the observation pier is fixedly connected with the nozzle of inclinometer pipe, while observation pier
Observed direction and the monitoring direction of deviational survey tube wall groove be consistent, the basic point of the inclinometer pipe is arranged at nozzle.
It is further that the inclinometer pipe is placed in the drilling being set in advance in slope soil, the side of the drilling
Face and bottom are equipped with concrete grouting, and drilling top perimeter is equipped with concrete protective structure, is set above concrete protective structure
There is openable concrete cover.
It is further that the depth of the concrete grouting of the foot of hole is not less than 50cm, concrete protective structure
Thickness is not less than 5cm.
The beneficial effects of the utility model are：By building appearance deformation observation pier beside side slope inclinometer tube orifice, and
And using inclinometer tube orifice as measurement basic point, the uncertain problem of inclinometer pipe datum mark is not only solved, compensates for inclinometer pipe sheet
The deficiency of body, and can side slope be carried out at the same time internal, dimensional deformation monitoring, play the role of being mutually authenticated, the structure energy
Enough compared with accurate judgement slope rock mass or the potential slide surface of the soil body, have great importance safely to Comprehensive evaluation engineering, it can
It is widely popularized in engineering.
Description of the drawings

Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model includes the inclinometer pipe 2 being vertically arranged in slope soil 1, the inclinometer pipe
The 2 nozzle sides for being located at 1 surface of slope soil are equipped with observation pier 3, and the observation pier 3 is fixedly connected with the nozzle of inclinometer pipe 2,
The observed direction of observation pier 3 and the monitoring direction of 2 tube wall groove of inclinometer pipe are consistent simultaneously, and the basic point of the inclinometer pipe 2 is set
It puts at nozzle.
Traditional inclinometer pipe is using tube bottom as datum mark, and movable clinometer probe is from the bottom of deviational survey tube wall groove to top
Portion moves, and then by the displacement of the gradient measured conversion horizontally (x to, y to), adds up successively from bottom to top
The offset of inclinometer pipe can be obtained, shows the moving displacement that rock mass or the soil body are occurred.But if deviational survey bottom of the tube
It is excessive and clinometer probe is caused to be unable to reach bottom that mobile or inclinometer pipe local deformation occurs for datum mark (or fixed point), not only
It will make observing buoy distortion and inclinometer pipe be substantially at the working condition scrapped, so as to can not accurate judgement deep rock mass or soil
The potential slide surface of body is unfavorable for the safety and stability of side slope.
The utility model by the nozzle of inclinometer pipe 2 set observation pier 3, observation pier 3 can by geodesic survey come
Observe the displacement of side slope (x to, y to) and vertical direction in the horizontal direction.Simultaneously to observation pier 3 and deviational survey when being observed every time
Pipe 2 is observed, so can be using 2 nozzle of inclinometer pipe as datum mark or fixed point, detection that the deformation of nozzle passes through side
The observation pier 3 of appearance deformation carrys out school survey.Then 2 observing buoy of inclinometer pipe only need to calculate each survey as datum mark when calculating using nozzle
The displacement of point, the displacement of nozzle are obtained by the horizontal displacement of observation pier 3.Deviational survey is obtained eventually by supplement and conversion
The accurate offset of pipe 2.
In order to play certain protective role to inclinometer pipe 2, the inclinometer pipe 2 is placed on and is set in advance in slope soil 1
In drilling 4 in, it is described drilling 4 side and bottom be equipped with concrete grouting 5, drilling 2 top perimeters be equipped with concrete protective
Structure 6, the top of concrete protective structure 6 are equipped with openable concrete cover 7.Concrete grouting 5 ensures that inclinometer pipe 2 is placed
Stability, concrete protective structure 6 and concrete cover 7 are used to protect the stability of nozzle and avoid being blocked.
Further, the depth of the concrete grouting 5 of 4 bottoms of the drilling is not less than 50cm, concrete protective structure 6
Thickness is not less than 5cm, to reach predetermined protective effect.
The utility model has the characteristics that simple, the easy for construction, reliable operation of calculating, successfully solves the benchmark of inclinometer pipe
Point or problem of fixed points, appearance deformation observation pier is built beside side slope inclinometer tube orifice, not only solves the benchmark of inclinometer pipe
Point problem, compensates for the deficiency of inclinometer pipe in itself, and can side slope be carried out at the same time internal, dimensional deformation monitoring, play phase
The effect mutually verified, actually kills two birds with one stone.The structure can be compared with accurate judgement slope rock mass or the potential slide surface of the soil body, to comprehensive
Overall merit engineering safety has great importance, and can be widely popularized in engineering.
