The length of the connecting piece 9 can be self-adjusted along with the pulling of the outside.
In the above embodiment, the steel wire mesh 10 is embedded in the mortar 6, the anti-cracking capability of the mortar 6 is improved by utilizing the tensile force of the steel wire mesh 10, and considering that the tensile force of the steel wire mesh 10 of a single piece is limited, therefore, in order to further improve the tensile force, the embodiment provides an embodiment, the steel wire mesh 10 is arranged into a plurality of pieces, the edges are stacked, the adjacent two pieces are connected by adopting the connecting piece 9, and the length of the connecting piece 9 can be self-adjusted along with the pulling of the outside, so that the connecting piece 9 can deform when the mortar is deformed due to thermal expansion and cold contraction, so as to offset the stress generated in the mortar deformation process, and the higher tensile force of the steel wire mesh can be utilized, and the stress generated by the mortar deformation can be offset by utilizing the deformation of the connecting piece 9.
In another embodiment, a specific connection mode of the connection member 9 is specifically provided, and includes: a connection sleeve 910, a partition 920 and two pull rods 930, wherein the connection sleeve 910 has a through hole penetrating along the height direction; the partition 920 is fixedly arranged in the connecting sleeve 910, and the partition 920 is perpendicular to the height direction of the connecting sleeve 910 and divides the inner space of the connecting sleeve 910 into two sections; two pull rods 930, one ends of which respectively extend into the connecting sleeve 910 from two ends of the connecting sleeve 910 and respectively penetrate through the partition 920, and the pull rods 930 can move relative to the partition 920 without falling off, and the other ends of the pull rods 930 are connected to meshes on the steel wire mesh 10 through a plurality of connecting belts; the two steel mesh sheets 10 respectively connected to the two tie bars 930 are adjacent to each other in the thickness direction without being squeezed.

Considering that if the steel wire mesh 10 is manually embedded in the mortar, the embedded depth of each position of the steel wire mesh 10 is easily inconsistent, and the mortar is also easily cracked over the years, in order to avoid the technical problem, in another embodiment, the steel wire mesh 10 is embedded in the mortar 6 under the extrusion action of the pushing mechanism 11, so as to ensure that the embedded depth of the whole steel wire mesh is consistent, and thus, the problem that the mortar is easily cracked due to the inconsistent embedded depth of each position of the steel wire mesh 10 in a long term is also avoided.
Another embodiment specifically provides a specific connection mode of the pushing mechanism 11, including: a planar plate 111, a plurality of connecting rods 112 and an operating rod 113, wherein the planar plate 111 is provided with a plurality of through holes; the connecting rods 112 correspond to the through holes one by one, one end of each connecting rod 112 penetrates through the corresponding through hole and is provided with a universal wheel 114, threads are arranged on the surface of each connecting rod 112, and a limiting bolt is arranged at the other end of each connecting rod 112; scales are arranged on the connecting rod; an operating lever 113 has one end connected to the plane plate 111 through a universal shaft and the other end for a user to hold.

For convenience of construction, the operating rod 113 can rotate in various directions along the universal shaft, thereby facilitating operation.
In another embodiment, said step E is further provided, if a crack is found, the specific remedial action of the remedial action is performed, and the specific remedial action comprises the following remedial steps:
e1, scraping the coating 7 within a preset range around the crack, then breaking and removing the mortar 6 within the range, shearing the steel wire mesh sheets 10 wrapped in the mortar 6 by using hydraulic shears, and finally scraping the waterproof putty 5 within the range to form a breaking pit;
here, the predetermined range around the crack may be an annular portion having a certain distance from the crack, for example, 2 cm.
Step E2, applying vibration to the inner side wall of the pit, and continuously scraping the paint 7, the mortar 6, the steel wire mesh 10 and the waterproof putty 5 of the area which shakes or cracks in the vibration process by adopting the operation of the step E1;
e3, detecting the strength of the wall surface except the pit, marking all the wall surfaces with the strength lower than the threshold value, removing the paint 7, the mortar 6, the steel wire mesh 10 and the waterproof putty 5 at all the wall surfaces with the strength lower than the threshold value by adopting the operation of the step E1, and applying vibration to the wall surface which is being removed for construction in the removing process;
e4, repeating the steps E2 and E3 until no wall surface with the strength lower than the threshold value exists, stopping, forming a repairing pit to be repaired at the moment, and exposing the reinforcing mesh of the wall surface adjacent to the repairing pit;

In the above embodiment, it is not necessary to directly remove the crack and the surrounding raw material, but considering that not only the small range of the cracked raw material such as mortar may have a problem, but there may be cracks in a larger range, but the removal range cannot be arbitrarily extended, and therefore a further precise extension range is required, it should be noted that the vibration intensity here is controlled so as not to affect the wall surface that originally has no crack, but the damaged portion that originally has small cracks but is not obvious and is slightly distant from the crack is further exposed, the crack and the damage are further extended, and the raw material of these portions is removed, and in case of emergency, the wall surface strength at the rest positions is detected by using equipment again, so as to ensure that there is no omission, and the removed portion is repaired, and the strength after repair can be achieved, and the original wall surface is not damaged. The two means are combined, all the wall surfaces with the defect problem can be guaranteed to be processed, and hidden dangers cannot exist.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
