In addition, anti-cracking and waterproof measures such as groove reserving, gluing and anti-cracking grid cloth are adopted at the joint, and the width of the anti-cracking grid cloth is set to be not less than 100mm; the other type is a prefabricated sandwich heat-insulation shear wall vertical joint which adopts a cavity structure, before concrete is poured at the indoor side, foam heat-insulation strips which are made of the same material and have the same thickness are filled in the cavity, a mortar-leakage-preventing adhesive tape is adopted for fixing, the bonding width is not less than 25mm, and a joint at the outdoor side is sealed by adopting a sealant. The reason for water leakage of the vertical joints of the two prefabricated shear walls is as follows: for the vertical joint of the common prefabricated shear wall, the vertical joint is mainly caused by unqualified rough surface arrangement of the connecting part of the prefabricated shear wall and the cast-in-place concrete and shrinkage deformation of the cast-in-place concrete; for the vertical joint of the prefabricated sandwich heat-insulation shear wall, the vertical joint is mainly caused by the poor sealing of the outdoor side joint sealant and the shrinkage of the cast-in-place concrete at the inner side.

The invention aims to provide an integrated method and system for detecting and repairing leakage water of a vertical joint of a precast concrete shear wall, which can accurately find out a leakage area so as to realize accurate repair of the leakage area.
To achieve the above object, the present invention provides an integrated method for detecting and repairing water leakage from a perps of a precast concrete shear wall, and please refer to fig. 1, which schematically shows a flow diagram of the integrated method for detecting and repairing water leakage from a perps of a precast concrete shear wall according to an embodiment of the present invention. As shown in FIG. 1, the method for detecting and repairing the water leakage of the perps of the precast concrete shear wall provided by the invention comprises the following steps:
s100, determining a detection area on the shear wall to be detected according to the type of the shear wall to be detected;
step S200, dividing the detection area to determine a plurality of detection points, and numbering each detection point in sequence according to the position information of each detection point on the detection area;

step S500, determining the area limited by all the leakage points as a leakage area according to the position information of each leakage point;
and S600, plugging and repairing the leakage area.
Therefore, the type of the detection area is determined according to the type of the shear wall to be detected, and the detection area with larger size is divided into a plurality of detection points to detect the humidity one by one; and the leakage judgment is carried out on each detection point respectively, so that all leakage points can be determined, the leakage area can be regularly and efficiently and accurately searched, and efficient and accurate leakage detection and repair are realized.
It should be noted that, as will be understood by those skilled in the art, the preset threshold may be set according to the climate environment of different regions, for example, the preset threshold may be set to 30%, since the leakage area cannot be effectively distinguished due to too large and too small threshold, according to the practical experience of the present invention, the detection effect is better when the threshold is 30%. It should be understood that the threshold may be different according to the climate environment of different regions, and will not be described herein.
In an exemplary embodiment, determining a detection area on the shear wall to be detected according to the type of the shear wall to be detected includes: and if the shear wall to be detected is a common precast concrete shear wall, taking the vertical seam with the leakage point on the shear wall to be detected as the detection area.
Specifically, in the actual process, two precast concrete shear wall modules are spliced to form a vertical joint or a section of cast-in-place concrete shear wall is reserved between the two precast concrete shear wall modules and forms a joint with the cast-in-place concrete shear wall, the joints are vertical joints which are through long from top to bottom, the vertical joints are likely to leak, the vertical joint with a leakage point on the shear wall to be detected is set as a detection area, and technicians can be effectively guided to use the method in a precast concrete shear wall detection scene to efficiently determine the detection area.
Further, dividing the detection area to determine a plurality of detection points includes: dividing the detection area into a plurality of line segments from top to bottom along the height direction of the detection area and by a first preset step length so as to determine a plurality of detection points, wherein the detection points are end points of the line segments.
Specifically, a digital axis coordinate system may be established with one end of the vertical seam as a first origin and as a starting point, a plurality of line segments may be set on the digital axis with the same first preset step length, and an end point of the line segment may be used as the detection point. Therefore, the detection is carried out on each detection point by utilizing the segmentation thinking, and the one-to-one investigation of each segmentation area is realized, so that the leakage points and the leakage areas are efficiently investigated.
Further, the method further comprises: and drawing a line graph for representing the corresponding relation between the position and the humidity according to the position information of each detection point on the detection area and the corresponding humidity value, wherein the line segments corresponding to different humidity ranges are represented by different colors. The method can clearly judge the leakage position and the leakage degree by combining the position and the corresponding color, so that technicians can judge the relative position of the leakage point in the detection area more intuitively, and the method is helpful for guiding the technicians using the method to search the leakage area and further repair the leakage area.
In another exemplary embodiment, determining a detection area on the shear wall to be detected according to the type of the shear wall to be detected includes: if the shear wall to be detected is a prefabricated sandwich heat-insulation shear wall, a rectangular area defined by two adjacent vertical seams on the shear wall to be detected and two upper and lower sidelines of the shear wall to be detected is used as the area to be detected, wherein at least one vertical seam has a leakage point.
Specifically, the detection area is formed by surrounding a first through long vertical joint and a second through long vertical joint of two adjacent concrete shear walls in the gravity direction and a first side line and a second side line of two ends of the concrete shear walls in the gravity direction, a rectangular area formed by surrounding the two adjacent vertical joints of the shear walls to be detected and an upper side line and a lower side line of the shear walls to be detected is set as the detection area, and technicians can be effectively guided to use the method in a precast concrete shear wall detection scene to efficiently determine the detection area.
Further, dividing the detection area to determine a plurality of detection points includes: and the width direction of the detection area is divided into a plurality of grids so as to determine a plurality of detection points, wherein the detection points are corner points of the grids.
Specifically, a planar rectangular coordinate system may be established with the first full-length vertical seam as a longitudinal axis and the first side line as a transverse axis, and an intersection point of the longitudinal axis and the transverse axis as a second origin; setting a plurality of transverse axis points in sequence with the second origin as a starting point and the same second preset step length on the transverse axis, and setting a plurality of longitudinal axis points in sequence with the second origin as a starting point and the same third preset step length on the longitudinal axis; and drawing a longitudinal straight line perpendicular to the transverse axis by taking each transverse axis point as a vertical foot, drawing a transverse straight line perpendicular to the longitudinal axis by taking each longitudinal axis point as a vertical foot, and taking the intersection points of all the longitudinal straight lines and the transverse straight lines, all the transverse axis points, all the longitudinal axis points and the second origin point as the detection points.
Therefore, the detection area is divided into a plurality of grids, the detection points are the corner points of the grids, so that the leakage search work of a large-area precast concrete shear wall can be detected and checked one by one through the detection points which are divided into small detection areas, the leakage area can be regularly, efficiently and accurately searched, and a good foundation is laid for realizing efficient and accurate leakage repair.
Specifically, the distance between the first through long perps and the second through long perps is 500 mm to 600 mm, and the length of each of the first through long perps and the second through long perps is 2800 mm. In a common fabricated concrete structure, the distance between two precast concrete shear wall modules is generally 500-600 mm, and the building layer height is generally 2800 mm, so that the limitation can effectively guide building structure construction detection personnel to use the method to detect and repair the water leakage in the detection area, and various related presetting and preparation are facilitated. It should be understood that for some non-standard storey buildings, the distance between the first through-length perps and the second through-length perps and their respective lengths may be different and will not be described in detail herein.
It should be noted that, as will be understood by those skilled in the art, the second preset step size and the third preset step size may be set according to specific situations, and the present invention is not limited to this, for example, the second preset step size may be set to 100mm, and the third preset step size may be set to 200 mm. After a plane rectangular coordinate system is established, the side length of the grid in the plane rectangular coordinate system can determine the density degree of the detection points. The larger the second preset step length and the third preset step length are, the more sparse the detection points are, and the poorer the detection effect is, but if the second preset step length and the third preset step length are too small, the detection points are too dense, so that the detection workload is too large, and the detection operation is inconvenient to perform. According to practical experience of the present invention, it is preferable to set the second preset step size to 100mm and the third preset step size to 200 mm. Under the condition, the density degree and the detection effect of the detection points can be considered, and a better detection effect is achieved.
It should be noted that, the conversion of the number into the position information is realized by algorithm conversion. For example, when the distance between the first full-length vertical seam and the second full-length vertical seam is 600 mm, the second preset step is 100mm, and the third preset step is 200 mm, the detecting points on the first transverse straight line may be sequentially detected in the positive direction of the transverse axis from the second origin, such as coordinates (0, 0) corresponding to number 1, coordinates (100, 0) corresponding to number 2, and coordinates (200, 0) corresponding to number 3, the like.a.no. 7. The like.coordinates (600, 0), and at this time, coordinates corresponding to number 8 should be (0, 200), because the detecting points of number 8 are already located on the second transverse straight line, at this time, the computational analysis module should be subjected to algorithmic setting, that is, the number is cycled at cycle 7, the transverse coordinates of the detecting points corresponding to the first number at the beginning of each cycle are returned to zero, and then continue to be incremented by 100, and the longitudinal coordinates of the detecting points at each cycle are increased by 200 with respect to the last cycle. When the transverse distance is x, the longitudinal distance is y, and the distance between the first vertical seam and the second vertical seam is d, the calculation formula of the period is d/y +1 and is rounded upwards, the detection point corresponding to each cycle end number generated by rounding upwards is arranged on the second vertical seam, the x is continuously increased by increasing the x after the horizontal coordinate of the detection point corresponding to the first number at the beginning of each cycle is reset to zero, and the y is increased relative to the vertical coordinate of the detection point of the previous cycle. By designing the step in this way, the humidity condition of each detection point in the detection area can be displayed on the computing device in an overall simulation manner, and the position of the leakage area can be efficiently and accurately judged on a comprehensive image. It should be understood that other algorithm conversion methods may also be used to realize the positioning of the detection points, and are not described herein again.
Further, the method further comprises: and drawing a plan for representing the corresponding relation between the position and the humidity according to the position information of each detection point on the detection area and the corresponding humidity value thereof, wherein the areas corresponding to different humidity ranges are represented by different colors. The method can clearly judge the leakage position and the leakage degree by combining the position and the corresponding color, so that technicians can more intuitively find the relative position of the leakage point in the detection area, and the method is helpful for guiding the technicians using the method to search the leakage area and further repair the leakage area.
Further, the shear wall is a prefabricated sandwich heat-preservation shear wall, and the step S600 specifically includes the following substeps:
in the substep S6001, marking the leakage area of the prefabricated sandwich heat-preservation shear wall;
a substep S6002, extracting the moisture in the heat-insulating layer covered by the leakage area;
and a substep S6003, sequentially repairing the heat-insulating material and re-gluing the leakage area from inside to outside of the wall body, wherein the re-gluing length is not less than 30mm when the normal glue is covered on the leakage area.
Therefore, by adopting the repairing method, reliable leakage repairing according to the standard requirement can be realized, so that the repairing operation of a room maintenance worker on the leakage area can be effectively guided, the leakage area can not leak any more by plugging the leakage water from the upstream surface of the prefabricated sandwich heat-insulation shear wall, and the integration of detection and repair of the vertical seam leakage water of the prefabricated sandwich heat-insulation shear wall is effectively realized.
It should be understood that, when the shear wall is a precast concrete shear wall, the step S600 specifically includes the following sub-steps:
step S6011, marking the leakage area of the precast concrete shear wall;
a substep S6012 of digging a V-shaped groove in the water facing area corresponding to the projection of the leakage area of the precast concrete shear wall along the thickness direction of the precast concrete shear wall, and removing water in the V-shaped groove to dry the groove;
and a substep S6013 of sealing the excavated V-shaped groove by using waterproof materials such as epoxy resin and the like, and repairing external waterproofing again under the condition of an external waterproofing process.
Therefore, by adopting the repairing method, the leakage points and the leakage areas on the precast concrete shear wall can be effectively repaired.
