Description
Technical Field
[0001] This application relates to the field of building construction technology, and in particular to a construction process for pre-embedded grouting pipes. Background Technology
[0002] When constructing buildings, a large amount of concrete is often used. If the construction site (such as a station) is located in a busy city center with traffic congestion, the transportation of concrete may be interrupted, making it impossible to guarantee a continuous supply of concrete. This affects the bonding between new and old concrete, which can lead to a decrease in the construction quality of the building. Furthermore, when constructing tall buildings, there may be concrete segregation or aggregate settling, which can also lead to a decrease in the construction quality of the building.
[0003] In related technologies, if a building exhibits issues such as the connection between old and new concrete or insufficient concrete pouring at the base, a groove is typically drilled at the problematic area. Concrete is then re-poured into the groove, and after solidification, further repairs are made to address the poor construction quality. However, this method requires significant manpower and can impact the construction cycle, presenting numerous disadvantages to the overall project. Summary of the Invention

DETAILED DESCRIPTION
[0045] The present application will be described in further detail below. Figures 1 to 7 The present application will be described in further detail below.
[0046] The embodiments of the present application disclose a pre-buried grouting pipe construction process.
[0047] When a building is constructed, a large amount of concrete is often used. If the construction site (for example, a station) is in the center of a bustling city, traffic congestion can cause the concrete to be interrupted during transportation, which cannot guarantee the continuous supply of concrete, and can cause cold joints of concrete. The inventors have found that if the construction is in summer, the weather is hot, and the slump of the concrete can be lost. The construction site directly adds water to the concrete to ensure the construction progress or for convenience, which causes the concrete to segregate or the slump to not meet the design requirements of the specification. Furthermore, the side wall of the station is high, and when the concrete is poured, the distance of free fall is large, which causes the concrete to segregate or the aggregate to sink, forming a rotten wall root. Alternatively, during construction, improper operation of the construction personnel can cause the steel bar to be tightly bound, the vibrating rod to be difficult to insert, and the phenomena of missing vibration, less vibration, and insufficient vibration to occur, which affects the density of the concrete.
[0048] In addition, during construction, there is incomplete garbage cleaning at the construction joint, which causes the concrete to be loose and not dense in the local area during the concrete pouring process. The installation position of the water stop is not centered, and the connection is not standardized. For example, the lap length of the steel plate water stop is not enough, the welding seam is not continuous, the connection of the steel edge rubber water stop is not subjected to hot melting treatment, or drilling is performed on the water stop for fixation, which causes leakage hazards. Or in the case where the concrete structure does not reach the design strength, the side wall formwork and support are removed in advance, which causes the concrete structure to crack. When large amount of concrete is poured for the station structure, in addition to the hydration heat of the concrete and the temperature difference between the inside and the surface of the concrete, cracks can also be generated. At the same time, if the curing is not timely or not in place, the newly poured concrete structure can also be cracked.
[0049] In the related art, the general process for repairing the concrete that leaks is as follows:
[0050] Finding the leakage point: the simplest and most effective way is to wipe the wall surface to be checked dry, and sprinkle a layer of dry cement on the wall. If there are wet points or lines, the position of the penetration joint can be determined. If the wet area is too large, another layer of dry cement powder can be sprinkled on it, so that the penetration position can be clearly seen.
[0051] Chiseling and drilling: for the penetration at the construction joint, a groove along the penetration joint should be chiseled first, and then drilling is performed in the groove.
[0052] Cleaning: after the above steps, the chiseled point should be carefully cleaned.
[0053] Embedding the grouting pipe 1: when the grouting pipe 1 is set, attention should be paid to align the center of the pipe opening with the hole, and then the grouting pipe 1 is fixed around it with caulking powder. For linear cracks, attention should be paid to seal all the chiseled parts. In places where it is not convenient to punch holes or embed the grouting pipe 1, foam strips can be used for sealing, but caulking powder should also be used for preliminary fixation.
[0054] Grouting: After the grouting pipe 1 is embedded, grouting is carried out, first, some colored water is used for initial filling, and after the filling is completed, the wall surface can be checked again, and when no leakage is found, grouting treatment can be carried out. If the range of grouting is large, one of the holes is left without grouting, and after the grouting of the other cavities is completed and there is no leakage, the grouting treatment is carried out on this hole.
[0055] Inspection: After the above process is completed, the inspection is carried out again by using the method of scattering dry cement, if there is no trace, it proves to be successful, if traces still appear, the above steps are repeated, if multiple grouting is unsuccessful, chemical grouting can be considered to be used for plugging.
[0056] However, the related art has the problems of repeated concrete leakage, unattractive appearance quality, long polishing time, long plugging time, and low work efficiency.
[0057] Therefore, a pre-embedded grouting pipe 1 construction process is provided Figure 1 The figure is a schematic view of repairing the root of a building in the embodiment of the present disclosure, Figure 2 The figure is a schematic view of repairing the construction joint in the embodiment of the present disclosure, see Figure 1 、 Figure 2 The construction process comprises the following steps:
[0058] S1: After part of the building is constructed, a grouting pipe 1 is installed at a position prone to leakage of the building;
[0059] S2: Another part of the building is constructed, and the grouting pipe 1 is arranged between the two parts of the building;
[0060] S3: Detecting the leakage point position of the two parts of the building;
[0061] S4: According to the leakage point of the building, grout is injected into the corresponding grouting pipe 1 of the leakage point.
[0062] In the embodiment of the present disclosure, when the building is constructed, the grouting pipe 1 is pre-embedded in the building, after the construction of the building is completed, if the building has a leakage position, after the leakage position is detected, grout is injected into the grouting pipe 1 corresponding to the leakage position, to achieve the purpose of plugging the leakage position. In this way, the process of needing to groove and drill the building in the later stage is reduced, which helps to save the cost of plugging the leakage position; at the same time, the grooved part does not need to be repaired in the later stage, which improves the efficiency of plugging the leakage position and also helps to improve the aesthetic degree of plugging the leakage position.
[0063] In some embodiments of the present disclosure, see Figure 3 、 Figure 4The grouting pipe 1 comprises a soft rubber pipe 12 and a hard plastic pipe 11; the hard plastic pipe 11 is coaxially arranged in the soft rubber pipe 12, wherein the hard plastic pipe 11 is provided with a discharging port 13, which facilitates the discharging of the slurry. During the construction of the part of the building, the soft rubber pipe 12 bears the external pressure of the concrete, and the soft rubber pipe 12 is tightly attached to the discharging port 13 of the hard plastic pipe 11 due to the pressure, so as to prevent the concrete slurry from mixing into the grouting pipe 1 during the pouring process. During the grouting process, when the pressure inside the grouting pipe 1 reaches a certain degree, the slurry can lift the soft rubber pipe 12 under the action of the pressure and overflow from the discharging port 13, so as to fill the leakage position and achieve the effect of plugging the leakage position.
[0064] Further, the soft rubber pipe 12 is in full contact with the building, so as to realize the sealing of the building, reduce the entry of external moisture into the two parts of the building, and play a certain sealing role.
[0065] In some embodiments of the present disclosure, in step S4, the grouting is performed at the lowest end of the grouting pipe 1. Such an arrangement can ensure sufficient grouting, so that more slurry can be attached to the leakage position, which helps to improve the repair quality of the leakage position of the building.
[0066] In some embodiments of the present disclosure, in step S1, the bending radius of the grouting pipe 1 is between 10mm and 20mm. When the gradual pipe is installed at the leakage position with a curved track, the bending radius of the grouting pipe 1 is set to be between 10mm and 20mm, so that when the slurry moves in the grouting pipe 1, the phenomenon of long grouting time caused by too large bending of the grouting pipe 1 or the phenomenon of easy blockage of the slurry in the grouting pipe 1 caused by too small bending of the grouting pipe 1 is reduced.
[0067] In some embodiments of the present disclosure, referring to Figure 5 In step S4, the feeding assembly 2 for feeding the slurry into the grouting pipe 1 is arranged; the feeding assembly 2 comprises a conveying pipe 21, a connecting pipe 22 and a first fixing member 23; the connecting pipe 22 extends into the grouting pipe 1 and is arranged in communication with the grouting pipe 1; the conveying pipe 21 is arranged at the other end of the connecting pipe 22 through the first fixing member 23, and is used for feeding the slurry into the connecting pipe 22.
[0068] In this embodiment, referring to Figure 6 The first fixing member 23 comprises at least two fixing blocks 231, a fixing bolt 232 and a fixing nut 233; the two fixing blocks 231 are rotatably connected to the connecting pipe 22, and a fixing space for the conveying pipe 21 is formed between the fixing blocks 231; the fixing bolt 232 penetrates through the oppositely arranged fixing blocks 231; and the fixing nut 233 is threadedly connected to the fixing bolt 232 and can abut against the fixing blocks 231.
[0069] Further, a pressure sensor is installed between the fixing block 231 and the conveying pipe 21 to monitor the pressure change between them in real time. When the fixing bolt 232 and the fixing nut 233 tighten the fixing block 231, the pressure sensor can record and feedback the pressure value between the fixing block 231 and the conveying pipe 21. The pressure sensor can detect whether there is uneven pressure distribution or loosening phenomenon during the fixing process. By monitoring the pressure change in real time, when the pressure between the fixing block 231 and the conveying pipe 21 reaches the preset value, the system confirms that the installation is stable and in place, ensuring the tight connection between the grouting pipe 1 and the connecting pipe 22, and improving the installation quality. During the construction process, the pressure sensor can also continuously monitor the connection state between the conveying pipe 21 and the connecting pipe 22. When an abnormal decrease in pressure value is detected, the system will issue an alarm to indicate that there may be a falling or loosening phenomenon. At this time, the construction personnel can check and re-fix in time to avoid grouting failure or construction delay caused by the falling of the conveying pipe. The data monitored by the pressure sensor can be transmitted to the remote control end through the wireless transmission module, which is convenient for the construction management personnel to monitor and adjust the grouting process in real time. When the system detects insufficient fixing pressure or the risk of falling, the remote control end can take immediate measures to ensure the continuity and safety of the construction.
[0070] In some embodiments of the present disclosure, referring to Figure 6 , the side of the fixing block 231 close to the conveying pipe 21 has a groove 2311 which is matched with the outer circumferential side of the conveying pipe 21. By setting the groove 2311 on the side of the fixing block 231 close to the conveying pipe 21, the fixing block 231 and the conveying pipe 21 can be more matched, the connection strength between the conveying pipe 21 and the connecting pipe 22 is improved, and the phenomenon of the conveying pipe 21 falling off during the grouting process is reduced, thereby improving the stability of the building repair.
[0071] In some embodiments of the present disclosure, referring to Figure 7 , the feeding assembly 2 further comprises a second fixing member 24; the connecting pipe 22 has an arc-shaped lug 221, and when the connecting pipe 22 extends into the grouting pipe 1, the arc-shaped lug 221 contacts the outer circumferential side of the grouting pipe 1; the second fixing member 24 comprises an arc-shaped abutting block 241 and a fixing screw 242; the arc-shaped abutting block 241 is provided with a through hole through which the connecting pipe 22 passes, and the arc-shaped abutting block 241 can abut against the side of the arc-shaped lug 221 away from the grouting pipe 1, and the fixing screw 242 is used to fix the arc-shaped abutting block 241 and the building. When the connecting pipe 22 extends into the grouting pipe 1 through the feeding port, the arc-shaped lug 221 provided on the connecting pipe 22 contacts and abuts against the outer circumferential side of the grouting pipe 1, then the arc-shaped abutting block 241 is adjusted, the arc-shaped abutting block 241 slides on the connecting pipe 22, after the arc-shaped abutting block 241 contacts and abuts against the arc-shaped lug 221, the arc-shaped abutting block 241 is fixed with the building through the fixing screw 242, thereby achieving the purpose of fixing the connecting pipe 22 and the grouting pipe 1.
[0072] In addition, a pressure sensor is arranged between the arc-shaped abutting block 241 and the arc-shaped lug 221 to monitor the installation effect and monitor the flow of grout in the grouting pipe based on pressure changes. Specifically, a pressure sensor is installed between the arc-shaped abutting block 241 and the arc-shaped lug 221 to monitor the pressure changes therebetween in real time. When the connecting pipe 22 is inserted into the grouting pipe 1 through the feed port and is fixed by the arc-shaped abutting block 241 and the fixing screw 242, the pressure sensor can monitor the pressure changes during installation to ensure stable and in-place installation. The pressure sensor can detect whether there is uneven pressure distribution or loosening during installation, so as to timely adjust the fixing member to ensure the tight connection between the grouting pipe 1 and the connecting pipe 22 and improve the installation quality. During the grouting process, the pressure sensor can also monitor the flow of grout in the grouting pipe 1 in real time. When the grout flows in the grouting pipe, it will cause pressure changes. By monitoring these changes, the system can understand the flow state of the grout in real time and determine whether there are problems such as blockage or abnormal flow rate. The monitored data can be transmitted to the remote control end through the wireless transmission module, which is convenient for construction management personnel to monitor and adjust the grouting process in real time, thereby improving the construction efficiency and quality.
[0073] In some embodiments of the present disclosure, the distance between adjacent arc-shaped abutting blocks 241 along the axial direction of the grouting pipe 1 is between 200-300 mm. In this way, on the one hand, the fixing effect of the grouting pipe 1 on the building can be improved, and on the other hand, the phenomenon of decreased grouting quality caused by movement of the grouting pipe 1 during grouting can be reduced.
[0074] In some embodiments of the present disclosure, the connecting pipe 22 is made of flexible material. In this way, by changing the angle of the connecting pipe 22, the connecting pipe 22 can be connected to the grouting pipe 1 at different positions of the leakage position, so that pre-buried grouting can be performed on different shapes of leakage positions.
[0075] In some embodiments of the present disclosure, a plurality of feeding assemblies 2 are arranged along the axial direction of the grouting pipe 1. In this way, selective grouting can be performed according to the leakage conditions of different leakage positions, which can reduce the waste of grout and reduce the repair cost of the leakage position while ensuring the repair effect of the leakage position.
