Problems solved by technology

[0005] Aiming at the problem that the connection between the existing newly-built road surface and the original old road surface is not tight enough to cause the connection position to be easily damaged, the present invention provides a road surface reconstruction method and equipment for road construction, which can be used on the road surface after cutting The side wall forms a concave groove, which is beneficial to increase the contact area between the new road surface and the original old road surface, and is conducive to improving the connection tightness between the new road surface and the original old road surface, and then put the end of the steel bar into the concave groove, The other end is placed in the excavated pit, and after the new concrete is sprayed into the pit and solidified, since one end of the steel bar is located in the concave groove on the side wall of the original old road, it can greatly increase the distance between the new road and the original road. The integrity of the old pavement increases the shear performance of the connection position and improves the service life of the new pavement

Embodiment 1

[0042] The existing technology generally uses a cutter to cut the pavement to be repaired, but it is easy to cut the stones in the road into two halves, causing the stones attached to the road to loosen due to vibration. The connection between the old pavement is not tight enough, resulting in cracks in the joint between the new pavement and the original old pavement during subsequent use, which in turn affects the service life of the road; for this reason, as figure 1 , Figure 5 , Figure 6As shown, this embodiment discloses a road surface reconstruction equipment for road construction, which includes a main frame 1, a control mechanism 2 and a cutting mechanism 3, the control mechanism 2 is connected to the main frame 1; the control The mechanism 2 is used to control the position and attitude of the cutting mechanism 3; the cutting mechanism 3 includes a bracket 301, a rotating shaft 302, and a cutting vertical column 304; A cutting edge is provided; the cutting edge is a...

Embodiment 2

[0049] A kind of pavement rebuilding method that is used for highway construction, adopts a kind of road surface rebuilding equipment that is used for highway construction described in embodiment 1, the following is specific explanation:

[0050] A road reconstruction method for highway construction, the steps of which are:

[0051] a. Adjust the height of the main frame 1 so that the cutting mechanism 3 is at an ideal height position, rotate the rotating shaft 302, drive the cam 303 to rotate, cooperate with the compression spring 305, and then drive the cutting vertical column 304 to move up and down in a cycle;

[0052] b. Turn the threaded column 201 to drive the first horizontal plate 202 and the second horizontal plate 203 to move downward, the first horizontal plate 202 drives the first connecting rod 204 to push the bracket 301 outward, and the second horizontal plate 203 drives the second horizontal plate 203 The two connecting rods 205 push the support 301 outwards, ...

Abstract

The invention discloses road surface reconstruction method and equipment for highway construction, and belongs to the technical field of road engineering. The road surface reconstruction equipment comprises a main machine frame, a control mechanism and a cutting mechanism, wherein the control mechanism is connected to the main machine frame; and the control mechanism is used for controlling the position of the cutting mechanism. According to the road surface reconstruction method and equipment for highway construction, disclosed by the invention, concave grooves can be formed on the side wallsof a cut road surface, so that the increase of a contact area of a newly built road surface and an original old road surface is facilitated, and the improvement of the connection tightness of the newly built road surface and the original old road surface is facilitated; and then the end parts of steel bars are put into the concave grooves, and the other end of the steel bar is put into excavatedpit slots; new concrete is sprayed into the pit slots and solidified; because one ends of the steel bars are located in the concave grooves on the side walls of the original old road surface, the integrity of the newly built road surface and the original old road surface can be greatly increased; the shear behavior of a connection position is increased; and the service life of the newly built roadsurface is improved.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a road reconstruction method and equipment for road construction. Background technique [0002] Road reconstruction refers to large-scale reconstruction of existing highways in order to improve their technical standards or technical grades according to the requirements of traffic volume development. Road reconstruction can be divided into total reconstruction and partial reconstruction. The former basically abandons the original road reconstruction, and the procedure is the same as that of the new road; the latter can be divided into route relocation, subgrade reconstruction, road surface reconstruction, and bridge and culvert reconstruction. During the use of existing roads, local damage will always occur. In order to improve the service life of the road, local reconstruction is often carried out on the local damaged parts to improve its technical standards...
