Description
Technical Field
The utility model relates to a direction control marking device is advanced on bridge culvert top belongs to box culvert top and advances construction technical field.
Background
The highway construction often meets the condition that an existing railway line needs to be penetrated. For the situation, construction is mostly carried out by adopting a prefabricated box culvert jacking construction method at present. In the jacking construction process, the control on the jacking direction of the prefabricated box culvert is the most important thing in the whole construction process.
In the existing bridge and culvert jacking construction, a method of positioning measurement by using a laser total station is usually adopted to control the jacking direction, but when the jacking distance is longer, the positioning measurement is carried out by using the laser total station singly, the measurement is inconvenient in actual construction, the measurement cannot visually reflect the number of jacked meters and the remaining in-place distance, whether a constructor deviates from the jacking center line or not and the jacking distance is not clear, so that the constructor waits too long for measurement time and the like, and the engineering jacking quality and the engineering progress are influenced.
Disclosure of Invention
To the above-mentioned defect that exists among the prior art, the utility model provides a convenient to use, the constructor of being convenient for can make clear and definite that the bridge has already pushed up to accomplish the distance and take one's place the surplus bridge culvert of surplus distance at last in the jacking in-process control box culvert central line and the constructor of being convenient for.
The utility model discloses a realize through following technical scheme: a bridge and culvert jacking direction control marking device is characterized in that: the jacking measuring device comprises a strip-shaped flat jacking measuring plate, wherein a jacking indicator mark is fixedly arranged on one plate surface of the jacking measuring plate every 0.5m and is vertical to the plate surface of the jacking measuring plate, and the height of the jacking indicator mark is 0.05 m; the jacking measuring plate is closely placed along the positions of a jacking central line and a side line on the slide plate after construction is completed, one side of the jacking measuring plate, which is provided with a jacking indicator, faces upwards, the other side of the jacking measuring plate is closely attached to the surface of the slide plate, and the jacking measuring plate is fixed on the slide plate through expansion screws.
Utilize the utility model discloses during the construction, along the position that finishes the slide plate's that reaches intensity that finishes constructing into the position of advancing central line, both sides sideline sets up respectively to advance to push up and measures the board, advances to push up and measure the board and hug closely and advance central line, sideline and place, adopt the inflation screw to fix. In the jacking process, constructors can perform jacking observation and measurement through the jacking measurement plate, and the deviation of the central line and the side line of the bridge and the culvert is prevented. The distance that the bridge and culvert have been jacked and the distance left after final positioning can be determined through the jacking indicator.
Furthermore, the jacking measuring plate and the jacking indicating sign are both PVC plates. Adopt the PVC board, the installation of being convenient for on the one hand, on the other hand also be convenient for push in-process box culvert and can cross the indicator of pushing in smoothly, continue the process of pushing in.
The utility model has the advantages that: the utility model discloses simple structure observes and measures the convenience, can effectively prevent to jack in-process bridge and culvert central line and sideline skew. The utility model discloses can not only guarantee constructor and advance the demand of in-process according to marking control box culvert central line direction in the top, pass through moreover the utility model discloses constructor can make clear and understand directly perceivedly that the bridge and culvert has pushed up and has accomplished the distance and take one's place remaining distance at last, is favorable to the rational arrangement of subsequent handling. The utility model discloses can improve the top and advance the construction the clear and definite nature of rectifying and the accuracy of top distance of advancing.

Detailed Description
The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:
as shown in the attached drawings, the device for controlling the line marking of the jacking direction of the bridges and culverts comprises a strip-shaped jacking measuring plate 1, wherein the jacking measuring plate 1 is made of a PVC plate material, a jacking indicator mark 2 is fixedly arranged on one plate surface of the jacking measuring plate 1 every 0.5m, and the jacking indicator mark 2 is perpendicular to the plate surface of the jacking measuring plate 1. The jacking indicator sign 2 is made of a PVC plate material, the height of the jacking indicator sign 2 is 0.05m, the width of the jacking indicator sign is 5cm, and the thickness of the jacking indicator sign is 1 cm. The jacking measuring plate 1 is placed along the positions of jacking center lines and side lines on the slide chair plate after construction is completed in a clinging mode, one side, provided with the jacking indicator sign 2, of the jacking measuring plate 1 faces upwards, the other side of the jacking measuring plate 1 clings to the surface of the slide chair plate, and the jacking measuring plate 1 is fixed on the slide chair plate through expansion screws.
Utilize the utility model discloses during the construction, at first on the slide chair board that finishes finishing reaching intensity of having under construction, fix a position out the central line point, the sideline point of box culvert advancing direction, adopt the ink line to couple together central line point, sideline point that have marked, mark out central line, sideline. And then the jacking measuring plate 1 is closely placed at the position of the surface layer of the sliding bed along the jacking central line and the side lines at the two sides, one side of the jacking measuring plate 1 provided with the jacking indicating sign 2 faces upwards, the other side of the jacking measuring plate 1 is closely attached to the surface of the sliding bed, and the jacking measuring plate 1 is fixed on the surface of the sliding bed by adopting expansion screws. In-process, constructor passes through in the top the utility model discloses carry out the top and advance the observation, prevent bridge and culvert central line and sideline skew. The in-process is gone into in the top at any time the utility model discloses whether drop, whether flush with play black line, whether the indicator is vertical in the top, whether the sign is obvious. And (4) acquiring and comparing jacking data every 10m, and repeating the steps until the position is acquired. According to the data analysis of jacking, the dynamic and continuous data comparison is carried out on the axis position in the bridge and culvert construction process, whether the light target data shot by the total station laser is consistent with the design axis or not is detected, and the accuracy of jacking measurement is greatly guaranteed.
Other parts in this embodiment are the prior art, and are not described herein again.
