Embodiment 1

[0038] Such as figure 1 As shown, the rapid maintenance method for cement pavement provided in this embodiment includes the following steps.

[0039] S101. Milling: Milling the road surface to be repaired, the milling depth is between 20mm and 25mm.

[0040] In the step S101, the existing road surface milling machine can be used to precisely mill the road surface to be repaired (that is, the cement road surface with problems such as broken boards, cracks, exposed bones, cracks, and misalignment).

[0041] S102. Removal of slag.

[0042] In the step S102, an existing road surface slag cleaning machine may be used to perform slag cleaning on the road surface that has just been milled.

[0043] S103. Scrubbing.

[0044] In the step S103, a high-pressure water gun may be used to flush the road surface.

[0045] S104. Keep the road surface wet for 4-6 hours.

[0046] In the step S104, wet means that the moisture content of the road surface is between 12% and 15%, or the relative...

Embodiment 2

[0064] This example provides a formula for the further preferred component dosage of the cement mortar described in Example 1, that is: in parts by weight, 383-428 parts of Portland cement, 556-610 parts of graded river Sand, 38-56 parts of stone powder, 27.5-31 parts of silicon powder, 10.9-11.8 parts of fly ash, 0.3-1.6 parts of calcium formate, 0.8-5.0 parts of triisopropanolamine, 1.3-2.7 parts of α-alkenylsulfonic acid Sodium, 0.9-1.9 parts of polyvinyl alcohol, 1.5-2.4 parts of anhydrous calcium chloride and appropriate amount of water are mixed.

[0065] The technical effect of this embodiment can be directly derived based on the beneficial effect of Embodiment 1, and will not be repeated here.

Embodiment 3

[0067] This example provides a formula for the further preferred component dosage of the cement mortar described in Example 2, that is, in parts by weight, 394-420 parts of Portland cement, 570-598 parts of graded river Sand, 45-52 parts of stone powder, 28-31 parts of silicon powder, 11-11.5 parts of fly ash, 0.4-1.2 parts of calcium formate, 1.8-4.4 parts of triisopropanolamine, 1.6-2.5 parts of α-alkenyl sulfonic acid Sodium, 1.0-1.7 parts of polyvinyl alcohol, 1.7-2.3 parts of anhydrous calcium chloride and appropriate amount of water are mixed.

[0068] The technical effect of this embodiment can be directly derived based on the beneficial effect of Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of buildings, and discloses a rapid maintaining method for a cement road surface. According to the created rapid maintaining method, the steps of milling,slag removing, brushing, wetting, new cement gel pouring, spreading of a new repair agent and plastic thin film maintenance are conducted sequentially, in this way, the quantity of demanded consumables can be decreased, construction method steps can be simplified, time needed for maintenance can be further shortened greatly, accordingly, the task of maintenance can be rapidly completed, the aim ofrapidly restoring traffic is realized, and travel of people and development of national economy activities are convenient greatly. In addition, the adopted cement gel and the repair agent have the advantages of having self leveling, being high in strength, realizing fast forming and resisting to freezing, permeation and abrasion, and the rapid maintaining method is convenient to apply and popularize actually.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a quick maintenance method for cement pavement. Background technique [0002] Cement concrete pavement is the main form of the current pavement. Under the repeated action of increasing traffic load and the cycle of various other environmental and human factors, it will inevitably be damaged to varying degrees. With the cement concrete pavement in service As time goes on, the degree of damage is increasing day by day, mainly manifested as broken boards, cracks, exposed, broken and wrong platforms, etc. In order to ensure the continuous and safe operation of traffic, it is necessary to repair the damaged cement concrete pavement. By comparing relevant industry norms and literature, we know that the strength of repair materials used in cement concrete pavement maintenance engineering must reach 70% of the design strength of the original concrete pavement within 24 h...
