Description
Technical field
The present invention relates to a kind of monitoring measurement field, roadbed subsidence point arrangement apparatus and method for embedding in specifically a kind of monitoring measurement.
Background technology
Underground engineering construction is to carry out in rock soil mass inside, and construction unavoidably produces disturbance to rock soil mass, and the stratum deformation that causes deforms above ground structure, structures and underground pipe network.When distortion acquires a certain degree, with the normal use that influences above ground structure, structures and underground pipe network, even the sedimentation accident takes place.Therefore in the intensive city of surface structures and underground utilities, the ground settlement situation and the control technology thereof of constructing and being caused are the problems that people extremely are concerned about always.
Ground settlement is the foundation ditch monitoring fundamental surveillance project of constructing, and it the most directly reflects the situation of change of the foundation ditch periphery soil body.The geometric leveling method is adopted in ground settlement observation, uses spirit-leveling instrument to observe.The data observation technical requirement is: monitoring point observation is by the third-class perpendicular displacement monitoring net of " Code for engineering surveying " GB50026-2007 technical requirement observation, and its technical requirement and observation points for attention require consistent with the buildings or structures deformation monitoring.
Ground settlement monitoring measuring point should be buried underground smooth, and preventing influences personnel and vehicle pass-through owing to be uneven, and simultaneously, measuring point is buried underground firmly, carries out clear marking, the convenient preservation.There are not similar monitoring equipment and method at present.
Summary of the invention
The objective of the invention is provides a kind of roadbed subsidence point arrangement apparatus and method for embedding for overcoming the deficiency of above-mentioned prior art, and this apparatus structure is simple, cost is low, easy for installation; This method is laid simple, and error is little.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
Roadbed subsidence point arrangement apparatus in a kind of monitoring measurement; Comprise measuring point reinforcing bar inserted link, measuring point thread cap, protection casing and over cap; Said measuring point reinforcing bar inserted link one end is conical Drilling head, and the other end is a smooth flat, and should upward link to each other with the measuring point thread cap through screw thread by end; Protection casing is sheathed on outside the measuring point reinforcing bar inserted link, and its upper end is provided with over cap.
Said protection casing is a plastic material.
Said over cap and protection casing are hinged.
The method for embedding of roadbed subsidence point arrangement apparatus in a kind of monitoring measurement, step is following:
(1) manual work to the road surface boring and coring, is taken out the ground core diameter greater than 5～10 millimeters of protection casing diameters with core drilling rig;
(2) protection casing is inserted in the boring get behind the core, the lateral wall of protection casing is close to the wall of a borehole, prevents that the wall of a borehole from subsiding;
(3) measuring point reinforcing bar inserted link taper one end is inserted in the boring, hit the other end, insert base course until measuring point reinforcing bar inserted link tapering point with iron hammer;
(4) the measuring point thread cap is linked to each other with measuring point reinforcing bar inserted link thread end, tighten, and guarantee that shiny surface one end of measuring point thread cap upper end is lower than 10～15 millimeters on road surface;
(5) with broken sandstone the space between protection casing and the measuring point reinforcing bar inserted link is filled, tamped, and guarantee that broken sandstone face is lower than the measuring point thread cap;
(6) over cap is linked to each other with protection casing through connecting screw, and lid is tight;
When (7) measuring, over cap is opened, the levelling pole bottom is positioned over measuring point thread cap shiny surface one end, just can carry out ground settlement and measure.
The present invention needed get core with core-drilling machine earlier before installing, and then, according to taking out core diameter, was equipped with the protection casing of corresponding specification, and sleeve pipe is installed in the rock soil mass, and rock soil mass around the extruding prevents shrinkage cavity, the hole of collapsing.Measuring point reinforcing bar inserted link is inserted in the rock soil mass of sleeve pipe inner bottom part, be lower than 5 centimeters places, protection casing critical point until smooth flat one end.With between protection casing and the measuring point reinforcing bar inserted link with broken sandstone fill up, compacting, prevent that rock soil mass pressure is excessive on every side, with protection casing crimp.For fear of since measuring point reinforcing bar inserted link when being driven into the road surface rock-soil layer; Smooth surface distortion and the measuring error that causes; After inserting the measuring point reinforcement rod, the measuring point thread cap is installed to the threaded end of measuring point reinforcement rod, the smooth surface that assurance contacts with dip stick, smooth.With over cap and protection casing hinge, cover protection casing then.The present invention has advantages such as the manufacturing materials cost is low, and distribution method is simple, and error is little.
