Description
Technical field
It the utility model is related to the device of monitoring Foundation Pit.
Background technology
, it is necessary to monitor the horizontal displacement data of the foundation ditch periphery soil body during foundation ditch operation, it is ensured that soil stabilization.Existing foundation ditch
Horizontal displacement monitoring method using total powerstation, it is necessary to carry out distance-measurement computation to multiple monitoring points of laying, and monitoring point
Laying mode, mainly there are two kinds.
Can monitor pier in ground casting concrete, in use, prism special is placed on monitoring pier, use total powerstation
Prism is observed.But monitoring pier needs cast in situs, and cost is higher, and concrete pier is stood upright on more than ground, and scene is applied
Work causes necessarily to hinder.
Can also monitor mark in embedded underground, after being flattened with tripod with the centering of monitoring mark, in tripod
Upper setting prism is observed for total powerstation.Although ground will not produce barrier, each Monitoring Data be required for tripod with
Label centering flattens, and operation is comparatively laborious, and the data precision is influenceed by accuracy of alignment.
Utility model content
Technical problem to be solved in the utility model is：A kind of dismountable pit displacement monitoring device is provided, can be square
Just in ground assembling and disassembling, ground obstacle will not be produced.
Technical scheme is used by the utility model solves its technical problem：
Dismountable pit displacement monitoring device, including locating sleeve and prism portion, the locating sleeve lower end are embedded in
Underground, upper end open are exposed from ground, and the prism subordinate portion is provided with the tube chamber of connection-peg, connection-peg profile and locating sleeve
Adaptation, and connection-peg insertion locating sleeve upper end, grafting head surface are additionally provided with mark or structure for determining insertion depth,
Prism portion top is provided with the prism for total station survey.
Further, the structure of the determination insertion depth is：Positioned at connection-peg upper end, and the position below prism, if
One put encloses the back-up ring stretched out to side face periphery.
Further, in addition to piling mat, be driven underground for auxiliary positioning sleeve pipe, the piling mat lower end be with
The column type of locating sleeve adaptation, upper end size range exceed the mouth of pipe of locating sleeve.
The beneficial effects of the utility model are：Above-mentioned pit displacement monitoring device, is to bury locating sleeve in monitoring site,
Prism portion top is provided with prism, and bottom is provided with connection-peg, during measurement, by connection-peg plug-in-sleeve, and both accurate fits,
Ensure precision, again take out in prism portion from sleeve pipe after measurement, place will not leave behind barrier, not influence site operation.
Brief description of the drawings
Fig. 1 is the schematic diagram of pit displacement monitoring device of the present utility model；
Reference is in figure：Locating sleeve 1, prism portion 2, connection-peg 21, back-up ring 22, prism 231.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Dismountable pit displacement monitoring device, including locating sleeve 1 and prism portion 2, the lower end of locating sleeve 1 are buried
In underground, upper end open is exposed from ground, and the bottom of prism portion 2 is provided with connection-peg 21, the profile of connection-peg 21 and positioning sleeve
The tube chamber adaptation of pipe 1, and connection-peg 21 inserts the upper end of locating sleeve 1, the surface of connection-peg 21 is additionally provided with for determining that insertion is deep
The mark or structure of degree, the top of prism portion 2 are provided with the prism 231 for total station survey.
As shown in Figure 1：Monitoring device, including locating sleeve 1 and prism portion 2, measurement prelocalization sleeve pipe 1 need to be embedded in prison
The underground of measuring point position, allows upper end open to expose from ground.During each measurement data, by prism portion 2 and the grafting of locating sleeve 1, i.e.,
It is that connection-peg 21 inserts the upper end of locating sleeve 1, is measured with total powerstation directed prism 231., can be by prism after measurement
Portion 2 is extracted from sleeve pipe, and ground will not leave behind barrier, not interfere with construction.
Connection-peg 21 is provided with mark or structure is used to determine insertion depth, such as can be that the side face of connection-peg 21 sets one
Bar graduation mark, it is ensured that the depth of insertion locating sleeve 1 is consistent every time.
It is preferable or positioned at the upper end of connection-peg 21, and position of the prism below 231, the one of setting encloses to side face
The back-up ring 22 that periphery is stretched out is used to determine insertion depth.Such as each grafting, require that back-up ring 22 pushes against the nose end of locating sleeve 1
Face, it is ensured that insertion depth is consistent.
The profile of connection-peg 21 is adapted to the tube chamber of locating sleeve 1, and connection-peg 21 can be inserted just in locating sleeve 1, no
Shake, reduce the error of installation, and then reduce the data error of measurement.
Above-mentioned monitoring device, when its locating sleeve 1 is buried, special piling mat can be coordinated to squeeze into ground by sleeve pipe with iron hammer
Under.Piling mat lower end is the column type being adapted to locating sleeve 1, can be stretched into pipe, and piling mat upper end size range exceeds
The mouth of pipe of locating sleeve 1, the mouth of pipe can be covered, then be beaten downwards with iron hammer, avoid damage to locating sleeve 1.
This monitoring device, the level land on foundation ditch periphery is can not only be provided at, can also be arranged on the slope of foundation ditch, be used for
Displacement of inclined plane monitors.
