Abstract
The utility model belongs to grade elevation control technology field, aluminium alloys is adopted to carry out measuring height in termination for solving, calculate that the elevation on the surface that paves is unfavorable for accurately objectively reflecting that the data of surface level and the collection paved are also on the low side, lack representational technical problem, provide a kind of grade elevation control device, comprise some drill rods being arranged symmetrically in road both sides, described drill rod layout perpendicular to the ground, drill rod is equal to the vertical distance of road both sides, the upper surface of described drill rod is all at same absolute altitude place, be respectively arranged with a longitudinal direction parallel with road at the drill rod upper surface of road both sides and lead to line, lead between line in two parallel longitudinal directions and horizontal control lines is set, horizontal control lines is with longitudinally logical line is vertical.The utility model road pavement can carry out tunneling boring elevation control by arranging horizontal control lines, and measurement result is closer to design elevation, and its fluctuating error is little, effectively raises Asphalt Surface.
Description
Technical field
The utility model belongs to grade elevation control technology field, is specifically related to a kind of grade elevation control device.
Background technology
In general bituminous pavement paving process, the control method of its absolute altitude carries out routine point after adopting hanging wire to measure asphalt surface course absolute altitude, by measuring the absolute altitude of wire rope, aluminium alloys (general long 3-4m) is utilized to carry out measuring height in termination, calculate the elevation on the surface that paves, utilize the method to be unfavorable for accurately objectively reflecting the surface level paved, the data gathered are also on the low side, lack representative.
Summary of the invention
The utility model adopts aluminium alloys to carry out measuring height in termination for solving, calculate data that the elevation on the surface that paves is unfavorable for accurately objectively reflecting surface level and the collection paved also on the low side, lack representational technical problem, provide a kind of grade elevation control device.
The technical solution adopted in the utility model is as follows:
A kind of grade elevation control device, comprise some drill rods being arranged symmetrically in road both sides, described drill rod layout perpendicular to the ground, drill rod is equal to the vertical distance of road both sides, the upper surface of described drill rod is all at same absolute altitude place, be respectively arranged with a longitudinal direction parallel with road at the drill rod upper surface of road both sides and lead to line, lead between line in two parallel longitudinal directions and arrange horizontal control lines, horizontal control lines and longitudinally logical line are vertical.
The beneficial effects of the utility model: the utility model leads between line in two parallel longitudinal directions and arranges horizontal control lines, road pavement tunneling boring elevation control can be carried out by arranging horizontal control lines, measurement grade elevation can be carried out at tunneling boring any place, can gather different data according to the requirement of certainty of measurement averages as the representative absolute altitude of this section, at any time paver sensor is adjusted according to level measurement result, control paver paving thickness.Adopt the utility model to carry out the measurement of grade elevation, measurement result is closer to design elevation, and its fluctuating error is little, effectively raises Asphalt Surface.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-drill rod, 2-is logical line longitudinally, 3-horizontal control lines, 4-road.
Detailed description of the invention
As shown in Figure 1, a kind of grade elevation control device, comprise some drill rods 1 being arranged symmetrically in road 4 both sides, described drill rod 1 layout perpendicular to the ground, drill rod 1 is equal to the vertical distance of road 4 both sides, and the upper surface of described drill rod 1, all at same absolute altitude place, is respectively arranged with a longitudinal direction parallel with road 4 at drill rod 1 upper surface of road 4 both sides and leads to line 2, lead between line 2 in two parallel longitudinal directions and arrange horizontal control lines 3, horizontal control lines 3 and longitudinally logical line 2 are vertical.
Described drill rod 1 is evenly arranged, and the distance between adjacent two drill rods 1 is equal, and the distance between adjacent two drill rods 1 requires to calculate according to certainty of measurement.
The utility model road pavement can carry out tunneling boring elevation control by arranging horizontal control lines 3, and measurement result is closer to design elevation, and its fluctuating error is little, effectively raises Asphalt Surface.At any time the verticality of drill rod 1, horizontal absolute altitude are monitored in work progress, adjustment in time of pinpointing the problems.
