The fracture, bending and crack resistance of the structural layer is mainly the cohesion provided by bonding the aggregates together through the cementing material. However, from the current municipal road disease investigation situation, most of the road diseases are the phenomena of cracking of the road surface in different degrees.
The prior art of the paver has the following defects: when the pavement structure material is uniformly paved by the paver, a pavement structure layer without continuous reinforced fibers is formed, the structural layer has weak bending and tensile resistance, shrinkage cracks or tensile cracks are easy to appear, the pavement strength and the service life are influenced, no difference exists in that short fibers are doped into the pavement structure material, the fiber continuity is poor, the stress effect cannot be reasonably exerted according to the material layer position, and the resource waste is easy to cause.
Disclosure of Invention
The utility model discloses the main technical problem who solves is attack and conk current paver and can not add the defect of continuous fiber function at the road surface structural material that paves, the utility model discloses can realize adding vertical continuous reinforced fiber when road surface structural material paves, improve road surface structural layer bending resistance and draw, anti-cracking performance.
In order to satisfy the purpose of the utility model, the utility model is realized by the following technical scheme: the utility model relates to a road surface unidirectional fiber structure layer paver device, including 5 subassemblies, be paver body 1, drawing drum 2, implant tooth 3, screed 4 and depth adjuster 5 respectively. The paver body 1 is a conventional mixed material paver in the market, and the paving width and the paving thickness of a structural layer of the paver can be freely adjusted according to the requirements of a design construction drawing; the pay-off reel 2 is a rotatable winding box and is a container for accommodating fiber reels, the number of the pay-off reels 2 is arranged at intervals along the road width, and the fibers are uniformly paid out by the rotation of the pay-off reels and implanted into the structural layer through the implanting teeth 3 while the mixture is spread; implant tooth 3 and be the tubulose part that a hard material does not have the tortuous, height-adjusting from top to bottom, inside be hollow structure, has certain intensity and hardness, guarantees not take place to warp at the paving in-process, and the material can be for stereoplasm plastic tubing, nonrust steel pipe etc. degree of depth regulator 5 is a carousel that can manual cisoid, implant tooth 3 with gear connection between the degree of depth regulator 5, through the extension value of rotating the carousel control and implanting the tooth, realize control implant tooth 3's elevation to control the position of fibre in the structural layer. The strickle 4 is the subsidiary girder steel in paver back for the mixture uplift portion that the tooth position caused is implanted when the tooth is implanted to the flattening and filling, and the strickle bottom should be smooth level, passes through bolted connection with the paver body from the paver board of taking, and the thickness of structural layer is controlled through former paver board. The device can directly implant the fibers into the set depth along the advancing direction of the paver when the paver is used for distributing the materials, and after the fiber-implanted paver is rolled and formed, the crack resistance and the fracture resistance of a pavement structure layer can be effectively enhanced, and the service life of a road is prolonged.
The utility model discloses the beneficial effect who reaches is:
the utility model discloses easily operation, low cost, use value is high, the fibre along road advancing direction has been added on traditional road surface structural layer's basis, can improve road surface structural layer's one-way rigidity, make mutually independent bulk material, except connecting through gelled material, still carry out interconnect through the one-way fibre of implanting, form and add the muscle structural layer, increase the wholeness of structural layer, make the structural layer change the plate body structure that forms each other and link to each other, thereby improve the anti crack resistance and the anti bending performance on road surface, prolong the life of road, thereby can reduce the maintenance frequency of road, practice thrift road later stage maintenance and maintenance expense.
