Description

Technical Field

[0001] The present application relates to the technical field of anti-floating anchor rod construction, and more specifically, to a method and device for waterproofing the top node of an anti-floating anchor rod. Background Art

[0002] Anti-floating anchor rods are primarily used to resist the buoyancy of groundwater. They provide pullout resistance through friction between the anti-floating anchor rod and the rock and soil layers. The ends of the anti-floating anchor rods are connected to the raft foundation of the underground garage. The most common construction method for anti-floating anchor rods penetrating the raft foundation is to first drill a hole using wet casing, then use rebar to form the rod skeleton, and finally use the bottom-of-hole grouting method to construct the anti-floating anchor rod. Waterproofing is then applied to the top of the anti-floating anchor rod and the raft pad of the underground garage, with a portion reserved for overlap with the raft waterproofing membrane. A waterproofing protective layer is then applied at the junction between the ends of the anti-floating anchor rods and the underground raft foundation. How to efficiently construct a waterproofing protective layer at the junction between the ends of the anti-floating anchor rods and the underground raft foundation is a research topic of interest.

[0003] Patent CN110616710B (application number: CN201910879492.9) provides a waterproof construction method for anti-floating anchor rod nodes. After the grouting of the anti-floating anchor rod is completed, before pouring the basement floor cushion layer, the groove mold is fixed to the anti-floating anchor rod by tying wire; the cushion layer concrete is poured around the groove mold; after the concrete around the groove mold meets the strength requirements, the groove mold is removed, and then the cushion layer surface within a certain range outside the groove is cleaned, the base treatment agent is applied, and then additional waterproof membrane is laid; after the construction of the additional waterproof membrane is completed, waterproof grease is filled into the groove, and then the waterproof membrane can be laid on the main surface of the basement; after the waterproof membrane is laid and inspected and accepted, a waterproof protective layer is poured on its upper part.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] Among the existing waterproofing treatment methods for anti-floating anchor nodes, waterproofing construction using waterproof grease is relatively simple and can be applied to different surfaces. However, the construction quality of the waterproof grease has a great influence on the waterproofing effect, and when it is impacted by external forces or the surface is damaged, it may be damaged and leaked, resulting in unstable waterproofing effect of the waterproof grease.

[0033] Based on the above reasons, an embodiment of the present application provides a method for waterproofing the top node of an anti-floating anchor rod, which includes: constructing the anti-floating anchor rod and the raft pad layer in sequence, reserving a groove around the end of the anti-floating anchor rod, spraying an alkaline cleaner or an acidic cleaner on the surface of the groove through a waterproof construction device, and applying a cement-based penetrating crystalline waterproof coating layer in the groove; laying a waterproof mortar layer and a polyester-based modified asphalt waterproof membrane layer on the raft pad layer in sequence, and laying the polyester-based modified asphalt waterproof membrane layer into the groove, and filling and sealing the groove with a hot-melt non-curing waterproof coating; wherein the waterproof construction device includes a fixed frame, a cylinder, a movable frame, a spray pump and a liquid storage tank, the cylinder is fixedly connected to the fixed frame and can drive the movable frame to move up and down, a plurality of spray heads are provided on the movable frame, the liquid storage tank is used to store alkaline cleaner or acidic cleaner, the liquid storage tank, the spray pump and the plurality of spray heads are connected in sequence through pipes, and when the spray pump is started, the alkaline cleaner or acidic cleaner is sprayed into the groove through the plurality of spray heads. The embodiment of the present application automatically constructs a cement-based penetrating crystalline waterproof coating layer on the raft cushion layer through penetration waterproofing, and performs stable waterproofing by penetrating the cement-based penetrating crystalline waterproof coating layer into the raft cushion layer, thereby improving the waterproof effect of the top node of the anti-floating anchor rod.

[0034] In some scenarios, a method for waterproofing the top node of an anti-floating anchor rod in an embodiment of the present application can be applied to the waterproof construction of the connection between the anti-floating anchor rod and the raft pad. By waterproofing the top node of the anti-floating anchor rod using this method, the waterproof stability of the anti-floating anchor rod can be improved.

[0035] The following describes in detail a method for waterproofing the top node of an anti-floating anchor provided in an embodiment of the present application with reference to specific examples.

[0036] Figure 1 A schematic diagram of a process for waterproofing the top node of an anti-floating anchor provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes S110 to S120, and S110 to S120 are described in detail below.

[0037] S110 , constructing the anti-floating anchor rod 1 and the raft cushion layer 2 in sequence, reserving a groove 11 around the end of the anti-floating anchor rod 1 , and applying a cement-based penetrating crystalline waterproof coating layer 111 in the groove 11 .

[0038] During construction, the anti-floating anchor rod 1 and the raft pad 2 are constructed in sequence, and then waterproofing is performed between the anti-floating anchor rod 1 and the raft pad 2, so that the waterproof effect of the top of the anti-floating anchor rod 1 can be ensured.

[0039] During construction, a groove 11 can be reserved around the end of the anti-floating anchor rod 1. The groove 11 is set on the raft pad 2. The groove 11 is used to construct the waterproof structure of the end of the anti-floating anchor rod 1. Applying a cement-based penetrating crystallization waterproof coating layer 111 in the groove 11 can waterproof the end of the anti-floating anchor rod 1.

[0040] For example, the diameter of the groove 11 may be 180 mm, and the depth of the groove 11 may be 50 mm.

[0041] During construction, the cement-based penetrating crystalline waterproof coating layer 111 forms microscopic crystals on the surface of the cement-based material, thereby reducing the permeability of the cement and improving the waterproofing effect. Furthermore, the cement-based penetrating crystalline waterproof coating layer 111 is resistant to chemical corrosion, aging, and wear, protecting the cement-based material from external environmental erosion and extending its service life.

[0042] When in use, the cement-based penetrating crystalline waterproof coating layer 111 can form crystals inside the cement-based material (the main structure of the raft cushion layer), providing a long-term waterproof effect. The cement-based penetrating crystalline waterproof coating layer 111 is resistant to aging and can resist erosion from the external environment for a long time.

[0043] S120, laying a waterproof mortar layer 112 and a polyester modified asphalt waterproof membrane layer 113 on the raft cushion layer 2 in sequence, laying the polyester modified asphalt waterproof membrane layer 113 into the groove 11, and filling and sealing the groove 11 with a hot-melt non-curing waterproof coating 114.

[0044] Figure 2 This is a schematic diagram of a waterproof treatment structure for the top node of an anti-floating anchor provided in an embodiment of the present application. Figure 3 for Figure 2 A partial schematic diagram of the waterproof treatment structure of the top node of an anti-floating anchor rod, as shown in FIG. Figure 2 and Figure 3 As shown, by sequentially laying a waterproof mortar layer 112 and a polyester modified asphalt waterproof membrane layer 113 on the raft cushion layer 2, the waterproof mortar layer 112 and the polyester modified asphalt waterproof membrane layer 113 can waterproof the entire raft cushion layer 2.

[0045] Structurally, the polyester modified asphalt waterproof membrane layer 113 is laid into the groove 11, so that the polyester modified asphalt waterproof membrane layer 113 can overlap with the cement-based penetrating crystalline waterproof coating layer 111 in the groove 11 to waterproof the end of the floating anchor rod 1.

[0046] Structurally, the groove 11 is filled and sealed with a hot-melt non-curing waterproof coating 114. The end of the polyester-modified asphalt waterproof membrane layer 113 can be sealed by the hot-melt non-curing waterproof coating 114, thereby ensuring the sealing of the polyester-modified asphalt waterproof membrane layer 113 in the groove 11.

[0047] Illustratively, the polyester-based modified asphalt waterproofing membrane layer 113 may be a 3+4 mm polyester-based modified asphalt waterproofing membrane (Type II).

[0048] For example, the width of the polyester-reinforced modified asphalt waterproof membrane layer 113 laid into the groove 11 may be at least 50 mm.

[0049] After the waterproof structure is constructed in S120 , a 50 mm thick fine stone concrete protective layer may be further laid on the polyester modified asphalt waterproof membrane layer 113 . The 50 mm thick fine stone concrete protective layer can protect the completed waterproof structure.

[0050] For example, after the construction of the anti-floating anchor rod is completed, a water-expanding rubber waterstop ring can be installed between 150mm and 200mm on the steel bar of the anti-floating anchor rod, and the raft foundation bottom plate concrete can be poured in time to complete the construction of the raft foundation.

[0051] The beneficial effect brought about by the above-mentioned implementation method is that the cement-based penetrating crystalline waterproof coating layer can form crystals inside the cement-based material (the main structure of the raft cushion layer), providing a long-term waterproof effect. At the same time, the cement-based penetrating crystalline waterproof coating layer has excellent aging resistance, can resist the erosion of the external environment for a long time, and can maintain the long-term waterproof effect of the anti-floating anchor rod.

[0052] In some implementations, the above method further includes: before applying the cement-based penetrating crystalline waterproof coating layer 111 in the groove 11, treating the surface of the groove 11 with an alkaline cleaner or an acidic cleaner to improve the penetration effect of the cement-based penetrating crystalline waterproof coating layer 111.

[0053] During construction, using an alkaline or acidic detergent to treat the surface of groove 11 removes impurities such as dirt, grease, and dust from the surface of groove 11, ensuring the adhesion and penetration of cement-based penetrating crystalline waterproof coating layer 111. The alkaline or acidic detergent also removes additives such as release agents and waterproofing agents from the surface of groove 11, preventing these agents from affecting the penetration of cement-based penetrating crystalline waterproof coating layer 111.

[0054] During construction, alkaline cleaners or acidic cleaners can expose the pores on the surface of the groove 11 to a certain extent, increase the permeability of the cement-based penetrating crystalline waterproof coating layer 111, and enable the cement-based penetrating crystalline waterproof coating layer 111 to better penetrate into the interior of the groove 11 to form crystals, thereby improving the waterproof effect of the anti-floating anchor rod end.

[0055] The beneficial effect brought about by the above-mentioned implementation method is that the surface treatment of the groove 11 using an alkaline cleaner or an acidic cleaner can improve the effect of the cement-based penetrating crystallization waterproof coating layer 111 penetrating into the interior of the groove 11 to form crystals, and further improve the waterproof effect of the cement-based penetrating crystallization waterproof coating layer 111 against the end of the floating anchor rod.

[0056] In some implementations, the above method further includes: spraying an alkaline detergent or an acidic detergent on the surface of the groove 11 by the waterproof construction device 3 .

[0057] During construction, the surface of the groove 11 can be treated by spraying alkaline cleaner or acidic cleaner through the waterproof construction device 3, thereby saving the labor cost of spraying alkaline cleaner or acidic cleaner on the groove 11 and improving the efficiency of spraying alkaline cleaner or acidic cleaner on the groove 11.

Figure 5 FIG. 1 is a bottom view structural diagram of a waterproof construction device according to an embodiment of the present application. Figure 4 and Figure 5 As shown, the waterproof construction device 3 includes a fixed frame 31, a cylinder 32, a movable frame 33, a spray pump 34 and a liquid storage tank 35. An opening is provided on one side of the fixed frame 31. The cylinder 32 is fixedly connected to the fixed frame 31 and can drive the movable frame 33 to move up and down. A plurality of spray heads 331 are provided on the movable frame 33. The spray pump 34 is used to store alkaline detergent or acidic detergent. The liquid storage tank 35, the spray pump 34 and the plurality of spray heads 331 are connected in sequence through pipes. When the spray pump 34 is started, the alkaline detergent or acidic detergent is sprayed into the groove 11 through the plurality of spray heads 331.

[0059] like Figure 4 and Figure 5 As shown, structurally, the waterproof construction device 3 includes a fixed frame 31, a cylinder 32, a movable frame 33, a spray pump 34 and a liquid storage tank 35. The fixed frame 31 is the main fixed structure of the waterproof construction device 3, and the cylinder 32 is a vertical drive component. The cylinder 32 is fixedly connected to the fixed frame 31 and can drive the movable frame 33 to move up and down. The movable frame 33 is an execution structure for processing the surface of the groove 11.

[0060] like Figure 4and Figure 5 As shown, a plurality of spray heads 331 are provided on the movable frame 33 , and the plurality of spray heads 331 are used to directly spray an alkaline detergent or an acidic detergent on the groove 11 to clean the groove 11 .

[0061] Functionally, the liquid storage tank 35 is used to store alkaline cleaner or acidic cleaner. The liquid storage tank 35, the spray pump 34 and multiple spray heads 331 are connected in sequence through pipes. The spray pump 34 serves as a power component to drive the alkaline cleaner or acidic cleaner. When the spray pump 34 is started, the alkaline cleaner or acidic cleaner is sprayed toward the groove 11 through the multiple spray heads 331 to achieve cleaning of the groove 11.

[0062] like Figure 5 As shown, in terms of structure, the cylinder 32 is eccentrically connected to the movable frame 33 so that the cylinder 32 will not interfere with the steel bars of the anti-floating anchor rod 1.

[0063] The beneficial effect brought about by the above implementation method is that the efficiency of spraying alkaline detergent or acidic detergent on the groove can be improved by using the waterproof construction device, thereby saving the labor cost when cleaning the groove.

[0064] The beneficial effect brought about by the above implementation is that the alkaline detergent or the acidic detergent is automatically sprayed into the groove by multiple spray heads, thereby achieving cleaning of the groove and improving the efficiency of cleaning the groove.

[0065] In some implementations, the horizontal cross-section of the fixed frame 31 is U-shaped, and one side of the movable frame 33 is provided with a frame opening 332 for passing the steel bars of the anti-floating anchor rod 1 .

[0066] like Figure 4 and Figure 5 As shown, structurally, the horizontal cross-section of the fixing frame 31 is U-shaped, so that the steel bars reserved above the raft pad 2 of the anti-floating anchor rod 1 can extend into the middle of the fixing frame 31, and the groove 11 can be cleaned through the movable frame 33.

[0067] like Figure 4 and Figure 5 As shown, structurally, one side of the movable frame 33 is provided with a frame opening portion 332 for passing the anti-floating anchor rod 1, so that the steel bars reserved above the raft pad 2 of the anti-floating anchor rod 1 can extend into the middle of the movable frame 33, and then the groove 11 can be cleaned through the movable frame 33.

[0068] The beneficial effect brought about by the above implementation method is that it facilitates the steel bars above the raft cushion layer 2 to extend into the middle of the fixed frame 31 and the middle of the movable frame 33, making it easy to clean the groove 11 through the movable frame 33, thereby ensuring the cleaning efficiency of the groove 11.

[0069] In some implementations, the waterproof construction device 3 further includes an air pump 36 and an air tank 37 , a plurality of cleaning heads 333 are provided on the movable frame 33 , and the air tank 37 , the air pump 36 and the plurality of cleaning heads 333 are connected in sequence through pipes.

[0070] like Figure 4 and Figure 5 As shown, the waterproof construction device 3 also includes an air pump 36 and an air tank 37. The air pump 36 is used to drive the air flow, and the air tank 37 is used to store high-pressure air. A plurality of cleaning heads 333 are provided on the movable frame 33. The cleaning heads 333 are used to spray high-pressure airflow to clean the dust in the groove 11. The air tank 37, the air pump 36 and the plurality of cleaning heads 333 are connected in sequence through pipes, so that the air tank 37, the air pump 36 and the plurality of cleaning heads 333 can cooperate with each other to spray high-pressure airflow to clean the groove 11.

[0071] In some implementations, the above method further includes: starting the air pump 36 to blow air toward the groove 11 through the multiple cleaning heads 333 to clean the groove 11 .

[0072] like Figure 4 and Figure 5 As shown, functionally, the groove 11 can be cleaned by starting the air pump 36 to blow air into the groove 11 through multiple cleaning heads 333, so that the dust and concrete particles in the groove 11 can be blown out of the groove 11 before the waterproofing construction, which can improve the effect of the cement-based penetrating crystallization waterproof coating layer 111 penetrating into the interior of the groove 11 to form crystals.

[0073] During use, by starting the air pump 36 and blowing air into the groove 11 through multiple cleaning heads 333 to clean the groove 11, the dust on the inner wall of the groove 11 can be cleaned, and the effect of the cement-based penetrating crystallization waterproof coating layer 111 penetrating into the interior of the groove 11 to form crystals can be improved.

[0074] The beneficial effect brought about by the above-mentioned implementation method is that the dust and concrete particles in the groove are cleaned by high-pressure airflow, which can improve the effect of the cement-based penetrating crystallization waterproof coating layer penetrating into the interior of the groove to form crystals.

[0075] In some implementations, the bottom surface of the groove 11 is an arc surface, the shape of the movable frame 33 and the shape of the groove 11 match each other, and the multiple cleaning heads 333 are arranged in multiple circles and radially distributed on the movable frame 33.

[0076] like Figure 4 and Figure 5 As shown, in terms of structure, the bottom surface of the groove 11 is an arc surface, so that the side walls of the groove 11 will not block dust and concrete particles, making it easy to clean the dust on the bottom surface of the groove 11.

[0077] Structurally, the shape of the movable frame 33 and the shape of the groove 11 cooperate with each other, and multiple cleaning heads 333 are arranged in multiple circles and radially distributed on the movable frame 33, so that the cleaning heads 333 on the movable frame 33 can comprehensively clean the dust in the groove 11 and can clean the dust in the groove 11.

[0078] The beneficial effect brought about by the above implementation is that the bottom surface of the groove is an arc surface, which makes it easy to clean the dust and concrete particles in the groove.

[0079] The beneficial effect brought about by the above implementation is that the shape of the movable frame and the shape of the groove match each other, and the multiple cleaning heads are arranged in multiple circles and radially distributed on the movable frame, so that the dust in the groove is easy to clean.

[0080] In some implementations, the output end of the cylinder 32 can be replaced with a vibrating heating plate 38. The cylinder 32 can drive the vibrating heating plate 38 to move up and down. The vibrating heating plate 38 is provided with a vibrating unit 381 and a heating unit 382.

[0083] In some implementations, the above method also includes: when using the hot-melt non-curing waterproof coating 114 to fill and seal the groove 11, the vibration heating plate 38 is driven downward by the cylinder 32 to contact the non-curing waterproof coating 114, and the non-curing waterproof coating 114 is vibrated and heated by the vibration heating plate 38.

[0084] During construction, when the hot-melt non-curing waterproof coating 114 is used to fill and seal the groove 11, the cylinder 32 can be used to drive the vibration heating plate 38 to move downward and contact the non-curing waterproof coating 114, so that the vibration heating plate 38 can act on the non-curing waterproof coating 114. The non-curing waterproof coating 114 is vibrated and heated by the vibration heating plate 38. After the non-curing waterproof coating 114 is heated, it can be ensured that the non-curing waterproof coating 114 seals the groove 11 at the optimal temperature, thereby ensuring the waterproof effect of the end of the anti-floating anchor rod 1; at the same time, the non-curing waterproof coating 114 ensures a high-compactness seal of the groove 11 after vibration, thereby improving the waterproof effect of the end of the anti-floating anchor rod 1.

[0085] The beneficial effect brought about by the above implementation is that the sealing and waterproofing effect of the non-curing waterproof coating against the end of the floating anchor rod can be improved through vibration and heating.

[0086] The beneficial effect brought about by the above-mentioned implementation method is that the output end of the cylinder can be replaced with a vibration heating plate, so that the end of the cylinder can be replaced with a movable frame or a vibration heating plate according to different construction stages, thereby improving the adaptability of the waterproof construction device, improving the use effect of the waterproof construction device, and further saving labor costs.

[0087] In some implementations, a plate opening 383 for passing the steel bars of the anti-floating anchor rod 1 is provided on one side of the vibration heating plate 38 .

[0088] like Figure 7 As shown, structurally, the plate opening 383 enables the vibration heating plate 38 to surround the steel bars of the anti-floating anchor rod 1, so that the vibration heating plate 38 can smoothly vibrate and heat the non-curing waterproof coating.

[0089] The beneficial effect brought about by the above implementation method is that the vibration heating plate can be smoothly surrounded by the steel bars of the anti-floating anchor rod through the opening of the plate body, making the vibration heating plate easy to use.

[0090] In some implementations, such as Figure 6 As shown, a temperature detection unit 384 is provided on the vibration heating plate 38, and the method further includes: detecting the temperature of the non-curing waterproof coating 114 by the temperature detection unit 384, and when the temperature of the non-curing waterproof coating 114 is lower than a preset temperature, starting the heating unit 382 to heat the non-curing waterproof coating 114.

[0091] During use, the temperature of the non-curing waterproof coating 114 can be detected by the temperature detection unit 384, so that the temperature of the non-curing waterproof coating 114 can be monitored. When the temperature of the non-curing waterproof coating 114 is lower than the preset temperature, the heating unit 382 is started to heat the non-curing waterproof coating 114, thereby maintaining the temperature of the non-curing waterproof coating 114 within the optimal sealing temperature range.

[0092] The beneficial effect brought about by the above implementation is that the temperature of the non-curing waterproof coating can be maintained within the optimal sealing temperature range, thereby ensuring the waterproof effect against the end of the floating anchor rod.

[0093] In some implementations, a roller 311 is provided at the bottom of the fixing frame 31 , and the roller 311 facilitates the movement of the waterproof construction device.

[0094] In some implementations, the air pump 36 is connected to the cylinder 32 via a pipe, and a solenoid valve is provided on the pipe connecting the air pump 36 and the cylinder 32 , so that the air supply of the air pump 36 to the cylinder 32 can be controlled by the solenoid valve.

[0095] In some implementations, the above method also includes: controlling the air pump 36 to drive the cylinder 32 to drive the movable frame 33 to move downward, starting the air pump 36 to blow air toward the groove 11 through multiple cleaning heads 333 to clean the groove 11, and after cleaning is completed, controlling the air pump 36 to drive the cylinder 32 to drive the movable frame 33 to move upward.

[0096] During construction, the air pump 36 is started to blow air into the groove 11 through the multiple cleaning heads 333 to clean the groove 11. The air pump 36 can also drive the cylinder 32 to drive the movable frame 33 to move, thereby realizing the reuse of the high-pressure gas generated by the air pump 36.

[0097] When the air pump 36 drives the cylinder 32 to drive the movable frame 33 to move, the air pump 36 can be controlled to drive the cylinder 32 to drive the movable frame 33 to move downward, and then the air pump 36 can be started to blow air toward the groove 11 through multiple cleaning heads 333 to clean the groove 11. After the groove 11 is cleaned by multiple cleaning heads 333, the air pump 36 can be controlled to drive the cylinder 32 to drive the movable frame 33 to move upward after cleaning is completed.

[0098] The beneficial effect brought about by the above implementation method is that the high-pressure gas generated by the air pump can be reused, which simplifies the equipment structure and complexity, reduces equipment costs, and reduces equipment failure rate.

[0099] In some implementations, the groove 11 is first cleaned by starting the air pump 36 to blow air into the groove 11 through multiple cleaning heads 333, then the surface of the groove 11 is treated by spraying an alkaline cleaner or an acidic cleaner through the waterproof construction device 3, and then the air pump 36 is started again to blow air into the groove 11 through multiple cleaning heads 333 to clean the groove 11 again.

[0100] When sealing the end of the anti-floating anchor rod 1, the air pump 36 can be started first to blow air into the groove 11 through multiple cleaning heads 333 to clean the groove 11. After the groove 11 is cleaned, the surface of the groove 11 can be treated by spraying alkaline cleaner or acidic cleaner through the waterproof construction device 3, which can improve the effect of cleaning the surface of the groove 11 with the alkaline cleaner or acidic cleaner. Finally, the air pump 36 is started again to blow air into the groove 11 through multiple cleaning heads 333 to clean the groove 11 again, so that the dust generated by the alkaline cleaner or acidic cleaner on the surface of the groove 11 can improve the cleanliness of the groove 11 again when the multiple cleaning heads 333 blow air into the groove 11, thereby improving the cleaning effect of the groove 11 and improving the waterproof effect of the anti-floating anchor rod 1.

[0101] The beneficial effect brought about by the above implementation method is that the waterproof effect of the anti-floating anchor rod is improved by first cleaning the groove with air, then cleaning the groove with an alkaline detergent or an acidic detergent, and finally cleaning the groove with air.

[0102] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
