Embodiment 1

[0085] Such as figure 1 As shown, the green upgrading and reconstruction construction method of old cement concrete pavement disclosed by the present invention includes the following steps: S1 construction preparation, S2 subgrade excavation, S3 drilling, S4 top crane combined system installation, S5 grout configuration, S6 groove filling, S7 jacking grouting treatment, S8 deep crack treatment, S9 broken plate treatment. When there are many diseases on the original pavement, follow this procedure for construction.

[0086] S1 construction preparation:

[0087] S1.1 Detection and analysis, detect and analyze the diseased pavement, detect the deflection value measured at 2 single points of the road slab on the diseased pavement, the deflection difference measured at the two sides of the joint, or detect the depth and width of the reflective crack; If the measured deflection value of a point is less than 0.14mm, the corresponding road surface will not be processed; when the mea...

Embodiment 2

[0132] Such as Figure 10 As shown, the green upgrading and reconstruction construction method of old cement concrete pavement disclosed by the present invention includes the following steps: S1 construction preparation, S2 subgrade excavation, S3 drilling, S4 top crane combined system installation, S5 grout configuration, S6 groove filling, S7 jacking grouting treatment, S8 deep crack treatment, S9 broken plate treatment. After completing the construction preparation of step S1 and determining the classification and treatment of pavement diseases, the steps of S6 slot filling, S7 jacking grouting treatment, S8 deep crack treatment, and S9 broken slab treatment are respectively selected, among which step S7 jacking grouting treatment Before the treatment, S2 subgrade excavation, S3 drilling, S4 top crane combined system installation, and S5 grout configuration are required.

[0133] When there are many diseases on the original pavement, follow this procedure for construction....

Embodiment 3

[0181] Based on embodiment 1, embodiment 2, as Figure 11 , Figure 12 As shown, the deep crack treatment in step S8 can be carried out in the following construction methods:

[0182] S8.1 Milling: Use a concrete slotting machine to mill the two original road panels in steps to form a step groove 20, and mill to the bottom of the deep crack 25; the step groove 20 has at least three layers, and the inner wall of the bottom step It is an inclined plane; the milled waste is cleaned up and watered to soak the concrete pavement on both sides of the step groove 20;

[0183] S8.2 Install the reinforcement frame: put the reinforcement frame tied with the horizontal reinforcement 33 and the longitudinal reinforcement 34 into the bottom groove, and the upper end of the reinforcement frame is equipped with a horizontal strut 35 along the horizontal direction; there are many horizontal struts 35, Evenly laid; the outer end of the transverse rib 33 is bent upwards or downwards; the botto...

Abstract

The invention relates to the technical field of pavement transformation, in particular to a construction method for green upgrading and transformation of old cement concrete pavement. The green upgrading and reconstruction construction method of the old cement concrete pavement disclosed by the present invention comprises the following steps: S1 construction preparation, S2 subgrade excavation, S3 drilling, S4 jacking combination system installation, S5 grout configuration, S6 groove filling, S7 jacking Grouting treatment, S8 deep crack treatment, S9 broken plate treatment. The construction method of the invention includes the detection, analysis and judgment of road surface diseases, which is convenient for quickly judging and distinguishing treatment measures for diseases in the actual construction process, and improves the construction efficiency of road surface reconstruction.

Description

technical field [0001] The invention relates to the technical field of pavement transformation, in particular to a construction method for green upgrading and transformation of old cement concrete pavement. Background technique [0002] In the traditional technology, a new cement concrete surface layer or asphalt concrete surface layer is directly added to the top of the original road surface, or the original road surface is destroyed and then re-constructed. These pavement restoration methods take a long time to construct, cost a lot, and waste the original cement concrete pavement. [0003] In order to solve the above problems, the Chinese patent with the authorized announcement number CN107227679A discloses a green renovation and upgrading construction method of cement concrete pavement, which calls out and analyzes the pavement disease, and then takes different treatment measures on the basis of the original cement pavement, so as to shorten the construction period, eff...
