Problems solved by technology

In recent years, general construction units usually use water glass, cement, etc. to fill water when dealing with water leakage from cracks. However, due to the high viscosity of water glass, cement, etc., the curing time is short, and it is impossible to penetrate deep into the bottom of the crack and completely fill the crack. Each part, in the gap that has not been filled, is prone to secondary cracking, resulting in secondary water leakage, and the effect of filling and repairing is poor

Embodiment 1

[0044] Embodiment 1" is substantially the same as Embodiment 1', the difference being that the cracks 11 of the wall body 1 in Embodiment 1" are distributed laterally.

Embodiment 1a

[0046] see Figure 1 to Figure 4 , a construction method of a crack repair structure that is simple and fast in construction, comprising the following steps:

[0047] Step1, open a V-shaped long groove 2 along the direction of the crack 11 on the part of the wall 1 where there are cracks 11. The depth of the V-shaped long groove 2 is 3cm, and fill the intertwined cotton thread and carbon fiber thread in the V-shaped long groove 2 as the filling line 41;

[0048] Step2.1, the first transparent polypropylene woven cloth 311, the first absorbent cotton cloth 312, the steel wire frame 313, the second absorbent cotton cloth 314 and the second transparent polypropylene woven cloth 315 are sequentially laminated and compacted to form the base layer 31;

[0049] Step2.2, after coating the upper and lower surfaces of the base layer 31 with UV-curable acrylic adhesive 32, fix the base layer 31 to the opening of the V-shaped long groove 2 through the anchor bolt 6, and close the opening...

Embodiment 1b

[0056] see Figure 1 to Figure 4 , a construction method of a crack repair structure that is simple and fast in construction, comprising the following steps:

[0057] Step1, open a V-shaped long groove 2 along the direction of the crack 11 on the part of the wall 1 where there are cracks 11. The depth of the V-shaped long groove 2 is 8cm, and fill the intertwined cotton thread and carbon fiber thread in the V-shaped long groove 2 as the filling line 41;

Abstract

The invention discloses a crack repairing structure capable of being easily, conveniently and quickly constructed and a construction method thereof. The problem that due to large viscosity of water glass, cement and the like, the filling repairing effect is poor is solved. According to the technical scheme, the crack repairing structure is characterized in that the crack repairing structure comprises a wall with a crack and a V-shaped long groove which is formed in the wall along the length of the crack and communicates with the crack; the V-shaped long groove is internally filled with a plurality of mutually-wound filling wires; an ultraviolet curing glue layer for sealing an opening is arranged in the position, located at the opening of the V-shaped long groove, of the wall in an attached mode; a flow guiding hole and an air guiding hole formed above the flow guiding hole are formed in the ultraviolet curing glue layer; the V-shaped long groove is internally filled with epoxy resin glue mixed with a curing agent through the flow guiding hole; and after the epoxy resin glue is cured, epoxy curing repairing layers which are arranged in the V-shaped long groove and the crack in a filled mode are formed. All positions of the crack can be filled, and seam sizes not filled with repairing materials are decreased in the repairing process.

Description

technical field [0001] The invention relates to building restoration, in particular to a crack repair structure with simple and fast construction and a preparation method thereof. Background technique [0002] About three months or a period of time after the construction of the exterior wall of the building, the physical structure of the concrete structure changes due to internal and external factors, forming cracks. This type of crack is generally completely cracked from top to bottom on the exterior wall. , cracked towards the inside of the wall, and has the characteristics of long and narrow and deep cracks. This easily causes damage and water leakage in the outer wall of the building through cracks. [0003] The generation of cracks not only affects the waterproofness of the structure, but is often accompanied by potential safety hazards; especially in underground engineering, concrete walls are restricted by the outside world, the environment (such as water and soil pr...
