Description

Technical Field

[0001] The invention relates to the technical field of waterproofing and moisture-proofing for underground garages, and in particular to a waterproofing and moisture-proofing paving structure system and method for underground garages. Background Art

[0002] At present, conventional basement floors include concrete cushion layer, waterproof layer, concrete structure floor, and floor surface layer from bottom to top. Since the waterproof layer is usually an organic waterproofing membrane, it has low strength and is easily damaged during construction. The organic material has poor durability and will age and break after long-term use. Moreover, damage at one point will cause the waterproofing effect of the entire surface to fail. One of the problems of the prior art is that there is a lack of effective monitoring means for damage to the waterproof layer, which makes it difficult to identify the damaged location after the waterproof layer is damaged, and the repair and construction of the waterproof layer is difficult, inefficient, and costly.

[0003] On the other hand, the concrete structure base is usually an ordinary concrete structure. Since the concrete contains a large number of pores and microcracks (at the micron level), the moisture and water vapor in the basement often easily penetrate into the concrete, causing various durability problems. Since the pores and microcracks are not easily discernible by the naked eye, the damage to the pavement structure caused by such leakage is easily overlooked. The second problem of the prior art is: there is a lack of effective monitoring of the leakage of the floor surface layer and the concrete structure base, making it difficult to determine the repair location, resulting in continuous damage.

[0004] In addition, when the underground water pressure is too high, water and water vapor can easily seep through the concrete to the ground surface, causing the basement to be damp. When water from the ground penetrates into the pavement structure, it is easy to cause moisture accumulation on the floor of the underground garage, affecting its service life. One reason for these problems is the third problem of the prior art, that is, the drainage efficiency of the pavement structure is poor, and the water that invades from above or below cannot be discharged in time. Summary of the invention

[0005] The present invention provides a waterproof and moisture-proof paving structure system and method for an underground garage, aiming to solve problems 1 to 3 existing in the prior art described in the background technology part.

[0006] To solve the above problems, the technical solution of the present invention is:

The paving structure comprises, from bottom to top, a plain concrete layer, a flexible waterproof layer, a lower structure self-draining layer, a water-proof layer, an upper structure self-draining layer, a flexible supporting layer, an anti-cracking moisture-proof layer and a floor surface layer.

The drainage detection system is pre-buried in the water-filtration concrete structure.

[0009] Preferably, the drainage detection system comprises an X-axis drainage channel and a Y-axis drainage channel which are intersected horizontally and vertically, and a sink is provided at the intersection of the X-axis drainage channel and the Y-axis drainage channel, the depth of the sink is greater than the depth of the lower end of the inner wall of the X-axis drainage channel and the Y-axis drainage channel, the sink is a cubic structure, the upper parts of the four side walls of the cubic structure are respectively connected to the X-axis drainage channel and the Y-axis drainage channel, and the two groups of opposite ends at the bottom of the inner wall of each sink are respectively connected to detection tubes arranged along the X-axis or the Y-axis. The detection tube includes a detection tube 1 and a detection tube 2 which are coaxially arranged opposite to each other. The opposite ends of the detection tube 1 and the detection tube 2 are respectively opened at the bottom of the opposite side walls of the sink tank. The other ends of the detection tube 1 and the detection tube 2 are respectively opened at two opposite outer wall surfaces of the upper structure self-draining layer and the lower structure self-draining layer along the X-axis or Y-axis to form a water outlet, and are connected with the drainage ditch. The upper structure self-draining layer and the lower structure self-draining layer are connected with the drainage ditch only through the water outlet. The sink tank is arranged in a matrix in the upper structure self-draining layer and the lower structure self-draining layer.

[0010] Preferably, the bottoms of the X-axis drainage channels and the Y-axis drainage channels between adjacent sinks are arc-shaped structures protruding upward, and the tops of the arc-shaped structures are located in the middle between the adjacent sinks.

[0011] Preferably, the detection tubes are arranged horizontally, and the sinks in the same row and column are connected in series through the detection tubes. Each sink is only equipped with two groups of detection tubes one and two. The two groups of detection tubes one and two are arranged along the X-axis and the Y-axis respectively.

[0012] Preferably, the X-axial drainage channel and the Y-axial drainage channel are both composed of porous pipes, the outer surface of the porous pipes is wrapped with a geotextile layer, the porous pipes are fixedly connected to the sink, and the porous pipes, sink and detection tube together constitute embedded parts prefabricated in the factory.

[0015] A method for using an underground garage waterproof and moisture-proof paving structure system includes a monitoring method 1 for monitoring the damage of a flexible waterproof layer and a monitoring method 2 for monitoring the leakage of an anti-cracking moisture-proof layer and a floor surface layer.

[0016] Preferably, the monitoring method 1 comprises the following steps:

[0017] (11) The monitoring personnel shall record in advance the coordinate position of each sink in the self-draining layer of the structure, i.e., the position along the X-axis and Y-axis;

[0018] (12) The outlets at the X-axis and Y-axis of the drainage ditch corresponding to the lower structure self-draining layer are monitored. If the amount of water accumulated in the lower structure self-draining layer is higher than the detection amount, all the outlets are discharging water, which is considered invalid data. If the amount of water accumulated is consistent with the detection amount, the accumulated water is only discharged from one or more groups of outlets at the X-axis and Y-axis. The positions of the two outlets in each group are recorded, and the corresponding sink position is determined by comparing with the drawing. The position of the damaged flexible waterproof layer is inferred based on the position of the sink.

[0019] Preferably, the monitoring method 2 is the same as the monitoring method 1, except that the location of leakage of the anti-crack moisture-proof layer and the floor surface layer is estimated.

[0031] Example 1

[0032] A waterproof and moisture-proof paving structure system for an underground garage, such as Figure 1-6As shown, it includes a waterproof ground beam 2 arranged along the bottom of the side wall 1 of the underground garage, a drainage ditch 3 arranged at the inner edge of the waterproof ground beam 2, and a paving structure arranged at the inner edge of the drainage ditch 3. The paving structure includes, from bottom to top, a plain concrete layer 4, a flexible waterproof layer 5, a lower structure self-draining layer 7, a waterproof layer 6, an upper structure self-draining layer 8, a flexible supporting layer 9, an anti-cracking and moisture-proof layer 10 and a floor surface layer 11.

[0033] The upper structure self-draining layer 8 and the lower structure self-draining layer 7 are respectively provided with drainage detection systems for detecting water leakage above and below. The drainage detection systems are connected to the drainage ditch 3, and the drainage ditch 3 is connected to an underground drainage pipe (not shown in the figure) through a pipeline.

[0034] In this embodiment, the functions of the waterproof ground beam are: 1. Strengthen the side wall of the underground garage and improve the waterproof effect of the side wall itself. It can be made of reinforced concrete structure coated with waterproof material; 2. Have a restraining effect on the pavement structure, such as Figure 1 As shown, it is beneficial to the stability of the paving structure.

[0035] The functions of the drainage detection system are: 1. To drain the water entering from below or above into the drainage ditch; 2. To provide coordinate reference to assist monitoring personnel in determining the location of leakage above or below, so as to facilitate the smooth progress of subsequent maintenance.

[0036] Example 2

[0037] Based on Example 1, this embodiment discloses: Figure 1-6 As shown, the upper structure self-draining layer 8 and the lower structure self-draining layer 7 have the same structure and are paved with water-filtration concrete. The water-filtration concrete is composed of the following raw materials in percentage by mass: 70% to 80% aggregate, 13% to 20% cement, 0.5% to 1.0% reinforcing material, 0.13% to 0.4% high-strength inorganic fiber, 0.4%-1.2% rubber powder, and 4% to 6% water. The drainage detection system is pre-buried in the water-filtration concrete structure.

[0038] In this embodiment, the water-filtering concrete facilitates the water intruding from below or above to enter the drainage detection system, thereby assisting the drainage detection system in draining and detecting.

[0039] Example 3

[0040] Based on Example 2, this embodiment discloses: Figure 1-6 As shown, the drainage detection system includes an X-axis drainage channel 13 and a Y-axis drainage channel 12 that cross each other horizontally and vertically, and a sink 17 is provided at the intersection of the X-axis drainage channel 13 and the Y-axis drainage channel 12.

[0041] The depth of the sink 17 is greater than the depth of the lower end of the inner wall of the X-axial drainage channel 13 and the Y-axial drainage channel 12. The sink 17 is a cubic structure. The upper parts of the four side walls of the cubic structure are respectively connected to the X-axial drainage channel 13 and the Y-axial drainage channel 12. The two groups of opposite ends at the bottom of the inner wall of each sink 17 are respectively connected to detection tubes 15 arranged along the X-axial direction or the Y-axial direction.

[0042] The detection tube 15 includes a detection tube 153 and a detection tube 2 154 which are coaxially arranged opposite to each other. Figure 6 As shown, the opposite ends of the detection tube 153 and the detection tube 2 154 are opened at the bottom of the opposite side walls of the sink 17, respectively. Figure 3-5 As shown, the other ends of the detection tube 1 153 and the detection tube 2 154 are respectively opened on two opposite outer wall surfaces of the upper structure self-draining layer 8 and the lower structure self-draining layer 7 along the X-axis or Y-axis to form a water outlet 16 and are connected to the drainage ditch 3.

[0043] The upper structure self-draining layer 8 and the lower structure self-draining layer 7 are connected to the drainage ditch 3 only through the water outlet 16, and the sinking tanks 17 are arranged in a matrix in the upper structure self-draining layer 8 and the lower structure self-draining layer 7.

[0044] like Figure 4 As shown, the bottoms of the X-axis drainage channels 13 and the Y-axis drainage channels 12 between adjacent sinks are upwardly protruding arc structures (not marked in the figure), and the tops of the arc structures are located in the middle between adjacent sinks 17.

[0045] like Figure 4 As shown, the detection tube is arranged horizontally, as shown in FIG. Figure 3-6 As shown, the sinks 17 in the same row and column are connected in series through detection tubes, and each sink 17 is only equipped with two groups of detection tubes 153 and 154, and the two groups of detection tubes 153 and 154 are respectively arranged along the X-axis and the Y-axis.

[0046] In this embodiment, water entering from the upper part enters the X-axial drainage channel 13 and Y-axial drainage channel 12 embedded inside the upper structure through the self-drainage layer 8. Since the bottom of the X-axial drainage channel 13 and Y-axial drainage channel 12 between adjacent sinks are upwardly protruding arc structures (not marked in the figure), water will accumulate in the sink.

[0047] When accumulated to a certain extent, water will enter the detection tube 1 153 and the detection tube 2 154 arranged along the X-axis and Y-axis directions, and be discharged from the water outlet along the detection tube 1 153 and the detection tube 2 154. Since the intersection of the two sets of detection tubes 1 153 and the detection tube 2 154 is the position of the sink, the coordinate position of the sink can be determined, that is, the coordinates in the X-axis and Y-axis directions. The water entering from the upper part preferentially enters the sink adjacent to the bottom by its own gravity. Therefore, according to the coordinate position of the sink, the location of cracks and leakage of the anti-crack moisture-proof layer and the floor surface layer can be inferred, so as to facilitate rapid maintenance.

[0048] Similarly, if the flexible waterproof layer is damaged, the water at the damaged part will preferentially enter the adjacent sink trough above due to transpiration or water pressure. When it accumulates to a certain level, it will drip or flow outward from the water outlet 16 along the X-axis and Y-axis directions of the detection tube 153 and the detection tube 2 154 connected to the sink trough 17. By observing the position of the water outlet, the position of the sink trough 17 can be determined, and the approximate position of the damage to the flexible waterproof scale can be inferred, that is, within the range below the sink trough.

[0049] Of course, there is an exception. For example, if the water invading from below rises slowly in the horizontal direction, then when it rises to a certain level, water will flow out of all the outlets (during the period of rising, transpiration has not caused enough water to accumulate in the sink above it so that it can be discharged through the detection tube); at this time, it is impossible to determine where the damage has occurred, that is, the data at this time is invalid, and the water needs to be discharged through the drain ditch, waiting for the water pressure to drop to a level that allows enough time for transpiration to allow the sink above to drain through the detection tube, or waiting for the water pressure to be high enough to directly transport the water to the sink above, and then the position of the sink, or even the damaged position, can be determined by the above method.

[0050] It should be noted that since the maintenance of the pavement structure requires a lot of manpower and material resources, this kind of monitoring and observation needs to be given sufficient time, and repeated confirmation should be carried out as much as possible before starting work.

[0051] In this embodiment, each sink 17 is only equipped with two groups of detection tubes 1 153 and detection tubes 2 154. The two groups of detection tubes 1 153 and detection tubes 2 154 are respectively arranged along the X-axis and the Y-axis. It should be understood that: there is one detection tube in the X-axis direction which is only disconnected in the sink, forming detection tube 1 and detection tube 2, so that the water in the sink can be discharged through detection tube 1 and detection tube 2.

[0052] Similarly, there is only one detection tube in the Y-axis direction that is disconnected in the sink, forming detection tube one and detection tube two, so that the water in the sink can be discharged through detection tube one and detection tube two; this means that the position of the sink is only related to the detection tubes in the X-axis and Y-axis directions. By finding these two detection tubes, the position (intersection) of the sink can be determined, and the water outlets of the two detection tubes are the basis for determining the positions of the two detection tubes (the positions of the detection tubes can be quickly determined in combination with the drawings).

[0053] Example 4

[0054] Based on Example 3, this embodiment discloses: Figure 4 As shown, the X-axial drainage channel 13 and the Y-axial drainage channel 12 are both composed of porous pipes, the outer surface of the porous pipes is wrapped with a geotextile layer (to prevent the holes from being blocked), the porous pipes are fixedly connected to the sink 17 (that is, the upper part of the side wall of the sink is provided with a connecting hole fixed to the porous pipe), and the porous pipes, the sink 17, and the detection tube 15 together constitute embedded parts prefabricated in the factory.

[0055] This embodiment discloses that the drainage detection system can be prefabricated in a factory, and then cast and embedded in the upper structure self-draining layer 8 and the lower structure self-draining layer 7 at the construction site. Among them, the drainage detection system is preferably a prefabricated structure that can be assembled on site.

[0056] Example 5

[0057] Based on Example 4, this embodiment discloses: Figure 1 As shown, the anti-crack and moisture-proof layer 10 is reinforced concrete with a thickness of 400-600 cm, and an anti-seepage admixture is mixed into the reinforced concrete, which mainly plays the role of load-bearing and anti-seepage.

[0058] like Figure 1 As shown, the waterproof layer 6 has the same structure as the anti-crack and moisture-proof layer 10, and the anti-crack and moisture-proof layer 10 is fine stone concrete with added steel fiber; or, the anti-crack and moisture-proof layer 10 is a polymer-modified thick layer cement-based self-leveling mortar.

[0059] In this embodiment, the waterproof layer 6 has the same structure as the anti-crack moisture-proof layer 10, and its main purpose is to isolate the water intruding from the upper part from the water intruding from the lower part, so as to ensure the effectiveness of the monitoring results. Of course, in order to further ensure the effectiveness, a waterproof coating can also be provided on the upper and lower surfaces of the waterproof layer 6.

[0060] It should be noted that in other structures of the present invention, the plain concrete layer is the cushion layer, and the flexible waterproof layer can be selected from synthetic polymer rolls or modified asphalt rolls, the rolls are bonded to each other by hot melt or self-bonded, and the rolls are bonded to the plain concrete layer by waterproof glue or self-bonded.

[0061] The flexible support layer is a thin fiber layer porous nonwoven fabric, porous woven fabric or non-porous polymer film material, and the flexible support layer is laid on the upper structure self-draining layer 8, and the anti-cracking moisture-proof layer is poured on the flexible support layer. The floor surface layer is one or more of a sealant cured floor, an epoxy floor, a polyurethane floor, a diamond abrasive wear-resistant floor, a terrazzo floor, and a self-leveling surface layer. Of course, the above structure can also be other prior art structures not mentioned.

[0062] Example 6

[0063] Based on the above embodiments, this embodiment discloses a method for using a waterproof and moisture-proof paving structure system for an underground garage, such as Figure 1-6 As shown, it includes a monitoring method 1 for monitoring the damage of the flexible waterproof layer 5 and a monitoring method 2 for monitoring the leakage of the anti-crack moisture-proof layer 10 and the floor surface layer 11.

[0064] Furthermore, the monitoring method 1 comprises the following steps:

[0065] (11) The monitoring personnel record in advance the coordinate position of each sink 17 in the structural self-draining layer 7, that is, the position along the X-axis and Y-axis;

[0066] (12) The water outlets 16 at the X-axis groove wall and the water outlets 16 at the Y-axis groove wall of the drainage ditch 3 corresponding to the lower structure self-draining layer 7 are monitored. If the amount of water accumulated in the lower structure self-draining layer 7 is higher than the detection amount, all the water outlets will discharge water (in order to judge whether it is higher than the detection amount), and this data is regarded as invalid data. If the amount of water accumulated is consistent with the detection amount, the accumulated water is only discharged from one or more groups of water outlets at the X-axis groove wall and the water outlets at the Y-axis groove wall (in order to reversely judge whether it meets the detection amount), and the positions of the two water outlets of each group are recorded, and the corresponding sinking trough position is determined by comparing with the drawing. The position of the damaged flexible waterproof layer is inferred based on the position of the sinking trough.

[0067] In this embodiment, only when water is flowing out of the water outlets in the X and Y axes can an effective detection result be obtained, that is, the coordinates of the sink can be determined, and even the location of the damage can be inferred.

[0068] like Figure 1-6 As shown, the monitoring method 2 is the same as the monitoring method 1, the difference being that the location of leakage of the anti-crack and moisture-proof layer and the floor surface layer is estimated.

[0069] The present invention can realize continuous and long-term monitoring of damage to the flexible waterproof layer and leakage of the anti-cracking moisture-proof layer and the floor surface layer through the above arrangement. It can not only assist the staff to timely determine the location of the damage or leakage, but also determine the severity of the damage or leakage according to the water output, and provide a strong reference for the subsequent maintenance of the paving structure, thereby improving the construction progress, saving manpower and material resources, and ensuring the waterproof performance of the base structure of the underground garage.
