Highway pavement base course elevation space control baseline frame device and using method thereof

Abstract

The invention discloses a highway pavement base course elevation space control baseline frame device and a using method thereof. The highway pavement base course elevation space control baseline frame device comprises a base, a vertical rod, a horizontal rod and a butterfly clamp; the vertical rod is vertically fixed to the base; the horizontal rod is horizontally arranged and movably connected to the upper portion of the vertical rod through the butterfly clamp; the butterfly clamp is a spring plate provided with wings on the four sides correspondingly; vertical limiting holes are formed in the two side wings in the vertical direction, and the vertical rod is arranged in the vertical limiting holes in a penetrating mode; and horizontal limiting holes are formed in the two side wings in the horizontal direction, and the horizontal rod is arranged in the horizontal limiting holes in a penetrating mode. The highway pavement base course elevation space control baseline frame device is easy to manufacture and low in manufacturing cost, construction site mounting and dismounting are quite convenient, and the highway pavement base course elevation space control baseline frame device can be permanently reused, meet the requirements of mechanized construction and standardized construction, and is suitable for large-scale continuous paving operation.

Description

technical field [0001] The invention relates to the technical field of high-grade highway pavement base construction, in particular to a highway pavement base elevation space control baseline frame device and its use method, which are convenient for quickly and accurately realizing the elevation of the base paving during highway pavement base construction. control. Background technique [0002] Adding stable aggregates such as gravel and gravel to cement makes the road pavement base have the characteristics of strong integrity, high bearing capacity, high rigidity, good stability and durability. It is the base structure commonly used in high-grade highways. In order to obtain higher quality in terms of geometric size, strength, surface smoothness, etc., the construction plan generally adopts the construction plan of centralized mixing method and paving the mixture with paver. [0003] Paver paving the base has the advantage of one-time molding, but if the elevation is not...

AI Technical Summary

Problems solved by technology

It is unscientific and cannot guarantee the large deflection of the steel wire rope in the middle of the two steel rods, so that the paved base will form a "wave-like" depression;

[0008] (4) For the base construction of high-grade highways, two-machine ladders are often used to pave at the same time. The construction method of hanging steel wire ropes is that after the paver passes the wire rope datum line, the steel wire rope cannot be removed in time due to the fastening relationship between the front and rear of the paver, which affects the timely operation of the road roller. Rolling the base layer is unfavorable to the formation of compaction degree, and the initial setting time of cement is required to be longer;

[0009] (5) The laying of the wire rope reference line is slow, requiring technicians to prepare a certain construction length in advance before paving the mixture, so that a very narrow (about 6m wide) and long (generally 500m or more), the difficulty of U-turn for the vehicles transporting the mixture is greatly increased, and the rubbing damage to the lower bearing layer is very serious due to multiple turns at large angles

[0010] (6) When the vehicle transporting the mixture turns around or backs up for a long distance, it will inevitably collide with the wire rope of the reference line, resulting in a change in the elevation of the wire rope of the reference line

Otherwise, it will result in wrong base elevation
