Description
Technical field
This utility model relates to a kind of level control point, specifically a kind of high accuracy level control point device, belongs to building and construction account field of engineering technology.
Background technology
At present, along with the fast development of civil engineering technology Yu building industry, the requirement of people's required precision to building construction is more and more higher.
Traditional level control point is the most directly embedded in hard Rock And Soil, and the impact being easily subject to construction, vibrations and other factors makes level control point be subjected to displacement, and affects certainty of measurement.It addition, traditional level control point is often easily subject to the destruction of the factors such as construction machinery because of restriction that construction site is narrow and small, also needs after destruction again to mend and set level control point, again check level, costly arduously, it is also possible to affect the precision of building and construction.
Summary of the invention
According to the deficiencies in the prior art, this utility model provides a kind of high accuracy level control point device, it is ensured that the requirement of certainty of measurement, reduces error, reduces because level control point occurs to destroy the cost being replaced, it is ensured that work efficiency.
This utility model is realized by techniques below scheme:
A kind of high accuracy level control point device, is foursquare concrete cushion including cover plate, the control point device of L-type, the concrete-pile protection device of circular platform type and cross section；Described control point device is embedded in the center of concrete-pile protection device; on the concrete cushion of level and the axis of concrete-pile protection device coincides the construction of described concrete-pile protection device with the vertical center line of concrete cushion, and described cover plate is arranged on the top of control point device.
Preferably, described cover plate is the integral plate of one piece of curved shape.
Preferably, described control point device cross-sectional diameter is 10mm～15mm.
Preferably, described control point device is to a length of 20mm～50mm exposing outside concrete-pile protection device upper surface.
Preferably, perpendicular with concrete-pile protection device upper surface to the control point device exposed outside.
Preferably, the concrete strength that described concrete-pile protection device uses is not less than C15.
Preferably, the concrete strength that described concrete cushion uses is C10.
Preferably, the height of described concrete-pile protection device is 600mm, and upper end osculum cross-sectional diameter is 200mm, and lower end big mouth cross-sectional diameter is 400mm.
Preferably, described concrete mats layer height is 100mm, and each edge lengths is 600mm.
This utility model beneficial effect:
Compared with prior art; this utility model one high accuracy level control point; it is additionally arranged concrete cushion, concrete-pile protection device and cover sheet; decrease because external factor causes level control point to deform the probability even destroyed; reduce error; ensure that the requirement of certainty of measurement, reduce because level control point occurs to destroy the cost being replaced, it is ensured that work efficiency.
