Problems solved by technology

[0004] However, it can also be seen that the existing technology and process cannot completely solve the problem of hollowing and cracking, and it is easy to crack at the cut section; repainting and repairing mortar will still cause hollowing or partial hollowing, which cannot solve potential safety hazards; A lot of construction waste, time-consuming and labor-intensive

Embodiment

[0026] Example: Combine figure 1 As shown, a kind of stucco mortar hollow drum bonding regeneration technology provided by the present invention specifically includes the following steps:

[0027] 1. Determination of hollowing range and hollowing layer;

[0028] 2. The length of the anchor is determined; the number of holes is determined, and the holes are drilled without dust and vibration at the same time;

[0029] 3. Hole cleaning treatment;

[0030] 4. Install the grouting anchor, and the anchor foot expands;

[0031] 5. Configure grouting material;

[0032] 6. Grouting, grouting inspection, grouting hole repair;

[0033] 7. Conservation to form a beautification layer, check and accept.

[0034] Wherein, the range of the hollow drum is determined by drilling samples or photographing the hollow drum, and the hollow drum layer is confirmed by listening to sounds or infrared imaging.

[0035] The length of the anchor is determined according to the thickness of the hollo...

Embodiment 1

[0037] Embodiment 1: Drill 16 holes within one square meter, all of which are anchor holes, inject resin into the hollow layer through the anchor nails, form the hollow hollow layer 7 for grouting, and form the hollow hollow layer for grouting where there is no grouting At the same time, after grouting, the surrounding circle is a grouting diffusion area 10, which is modified by a beautification layer 11 after grouting.

Embodiment 2

[0038] Embodiment 2: In this embodiment, 41 holes are drilled in a plum blossom arrangement, 25 holes in the 41 holes are used to install anchors, and the remaining 16 holes are not equipped with anchor holes, but simple grouting holes, and The distance between each two holes is not greater than 330mm. During the drilling process, the 25 holes with anchors are processed first. After the overall inspection, the 16 holes without anchors are completed in turn. Check to determine whether supplementary drilling is required. At the same time, the drilling is performed through a special drill bit and a drill pipe, wherein a collection device is provided at the end of the drill pipe to collect the sewage and dirt generated by the drilling. At the same time , the drill bit is made of corundum.

[0039] When configuring the grout, use a special polymer grout, use cement-based polymer or resin as the raw material, the viscosity is 100-100000, the bond strength is greater than 0.7MPA, the...

Abstract

The invention discloses a painting mortar empty drum bonding regeneration technology. The technology specifically comprises the following steps of 1, determining an empty drum range and determining anempty drum layer; 2, determining the length of an anchor nail, determining the number of distributing holes, and carrying out dust-free and vibration-free punching; 3, cleaning the holes; 4, installing grouting anchor nails and expanding anchor nail pins; 5, configuring a grouting material; 6, carrying out grouting, grouting inspection and grouting hole repairing; and 7, carrying out maintenanceand acceptance. The painting mortar empty drum bonding regeneration technology is simple, stable in quality, low in cost, high in efficiency, safe and reliable, saves resources, reduces construction waste, and is green and environmental-protecting.

Description

technical field [0001] The invention belongs to the technical field of building repairs, and in particular relates to a technology for hollow-drum bonding regeneration of plaster mortar. Background technique [0002] When the hollowing of the plastering mortar occurs, the existing technology is to use cutting to remove the hollowing area, treat the area with an interface agent, and then re-prepare new plastering mortar or polymer modified mortar or mix fibers into the mortar for repainting. [0003] The process flow of the prior art: judging the range of hollowing—cutting along the periphery of the hollowing—eliminating the hollowing layer—cleaning the base layer—preparing interface agent—painting interface agent—configuring repair mortar—painting repair mortar. [0004] However, it can also be seen that the existing technology and process cannot completely solve the problem of hollowing and cracking, and it is easy to crack at the cut section; repainting and repairing morta...
