Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a medical-grade anti-leakage septic tank structure and a construction method thereof. Background Art

[0002] The traditional anti-leakage measure for finished septic tanks is to use waterproof mortar to plaster the joints between the tanks. The process is relatively simple and the anti-leakage performance is average. In projects such as hospitals that have high requirements for anti-leakage of septic tanks, septic tanks are also used to store medical pollutants. It is difficult to meet the anti-leakage requirements using only waterproof mortar, and there is a risk of pollutant leakage. If an integral cast-in-place septic tank is used, the overall anti-leakage effect of the septic tank can be guaranteed, but the cast-in-place septic tank consumes a long construction period, while the installation of a finished septic tank is simpler and faster. Summary of the invention

[0003] In order to overcome the defects of the prior art, a medical-grade anti-leakage septic tank structure and a construction method thereof are now provided to solve the problem that the anti-leakage performance of traditional finished prefabricated septic tanks cannot meet the high-demand construction projects.

[0004] In order to achieve the above object, a medical-grade anti-leakage septic tank structure is provided, comprising:

[0005] A plurality of prefabricated septic tanks, wherein the plurality of prefabricated septic tanks are spliced ​​together horizontally, and the prefabricated septic tanks include multi-layer septic tank bodies spliced ​​together vertically, wherein two upper and lower adjacent layers of septic tank bodies are connected by tongue and groove, and a water-stop steel plate is buried in the upper opening of the top layer of the septic tank body;

[0006] Epoxy resin mortar, the first joint seams of the two upper and lower adjacent septic tank bodies are filled with the epoxy resin mortar, and the second joint seams of the upper openings of the two left and right adjacent prefabricated septic tanks are filled with the epoxy resin mortar;

[0007] A cast-in-place base for installing a pool cover is cast on the upper opening of the prefabricated septic tank and is arranged in a circle along the circumferential direction of the upper opening of the prefabricated septic tank. The upper part of the water-stop steel plate is buried in the cast-in-place base.

[0008] Furthermore, the top of the pool wall of the lower septic tank body is formed with plug-in ridges, and the plug-in ridges are arranged in a circle along the circumferential direction of the lower septic tank body. The bottom of the pool wall of the upper septic tank body is formed with a tongue and groove, and the plug-in ridges are inserted in the tongue and groove. The epoxy resin mortar is filled between the top of the pool wall of the lower septic tank body and the bottom of the pool wall of the upper septic tank body.

[0009] Furthermore, the width of the plug-in ridges gradually decreases from bottom to top.

[0010] Furthermore, the cross section of the plug-in ridge is an isosceles trapezoid.

[0011] Furthermore, the width of the portion of the water-stop steel plate extending to the upper opening of the top septic tank body is 200 mm.

[0012] The present invention provides a construction method of a medical-grade anti-leakage septic tank structure, comprising the following steps:

[0013] The multi-layer septic tank bodies are vertically spliced ​​together to form a prefabricated septic tank, and then the multiple prefabricated septic tanks are horizontally spliced ​​together to form a prefabricated septic tank, wherein the upper and lower adjacent layers of the septic tank bodies are connected by tongue and groove, and at the same time, the first splicing seams of the upper and lower adjacent layers of the septic tank bodies are filled with epoxy resin mortar, and the second splicing seams of the upper openings of the two left and right adjacent prefabricated septic tanks are filled with epoxy resin mortar;

[0014] A cast-in-place base for installing a pool cover is formed by pouring at the upper opening of the prefabricated septic tank. The cast-in-place base is arranged in a circle along the circumferential direction of the upper opening of the prefabricated septic tank so that the upper part of the water-stopping steel plate is buried in the cast-in-place base.

[0015] The beneficial effect of the present invention is that the medical-grade anti-leakage septic tank structure of the present invention adopts a prefabricated septic tank as the main body, and casts a cast-in-place base to install a concrete tank cover, which saves construction time and ensures the stability and integrity of the septic tank while ensuring the excellent anti-leakage effect of the finished septic tank. The prefabricated septic tank joints of the medical-grade anti-leakage septic tank structure of the present invention innovatively use epoxy resin mortar instead of waterproof mortar. Epoxy resin mortar has higher bonding force, higher compressive strength, and more stable chemical properties, which greatly improves the anti-leakage performance of the septic tank and extends the service life of the septic tank. The medical-grade anti-leakage septic tank structure of the present invention connects the prefabricated septic tank and the cast-in-place structure into a whole by reserving a water-stop steel plate on the prefabricated septic tank, ensuring that no leakage will occur at the connection of the prefabricated septic tank. The vertical joint structure of the prefabricated septic tank of the medical-grade anti-leakage septic tank structure of the present invention innovatively adopts tongue-and-groove connection, increases the bite area to improve the overall stability, and uses epoxy resin mortar for consolidation, which can effectively prevent mutual leakage on both sides of the tank wall.

It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Reference Figures 1 to 6 As shown, the present invention provides a medical-grade anti-leakage septic tank structure, including: a prefabricated septic tank 1, epoxy resin mortar 2, and a cast-in-place base 3.

[0026] In this embodiment, the prefabricated septic tank is composed of a plurality of prefabricated septic tanks 1. The plurality of prefabricated septic tanks 1 are spliced ​​together transversely.

[0027] The prefabricated septic tank 1 includes a multi-layer septic tank body 11. The multi-layer septic tank body 11 is vertically spliced ​​together. Figure 1 and Figure 2 As shown, two adjacent septic tank bodies 11 are connected via tongue and groove.

[0028] A water-stopping steel plate 12 is buried in the upper opening of the top septic tank body 11 .

[0029] The first joint seams of the two upper and lower adjacent septic tank bodies 11 are filled with epoxy resin mortar 2. The second joint seams of the upper openings of the two left and right adjacent prefabricated septic tanks 1 are filled with epoxy resin mortar 2.

[0030] The cast-in-place base 3 is cast on the upper opening of the prefabricated septic tank 1 and is arranged in a circle along the circumferential direction of the upper opening of the prefabricated septic tank 1. The upper part of the water-stop steel plate 12 is buried in the cast-in-place base 3. The cast-in-place base 3 is used to install the pool cover.

[0031] The cast-in-place base and pool cover are cast-in-place using radiation-proof concrete. In some embodiments, the cast-in-place base and pool cover are cast in one piece.

[0032] Continue reading Figure 2 As shown, the top of the wall of the lower septic tank body a is formed with a plug-in rib 13. The plug-in rib 13 is arranged in a circle along the circumferential direction of the lower septic tank body a. The bottom of the wall of the upper septic tank body b is formed with a tongue and groove. The plug-in rib 13 is inserted in the tongue and groove. The epoxy resin mortar 2 is filled between the top of the wall of the lower septic tank body a and the bottom of the wall of the upper septic tank body b.

[0033] As a preferred embodiment, the width of the plug-in ridges 13 gradually decreases from bottom to top.

[0034] In this embodiment, the cross section of the plug-in ridge 13 is an isosceles trapezoid.

[0035] As a preferred implementation, see Figure 4 As shown, the width of the portion of the water-stop steel plate 12 extending to the upper opening of the top septic tank body 11 is 200 mm.

[0036] The present invention provides a construction method of a medical-grade anti-leakage septic tank structure, which is characterized by comprising the following steps:

[0037] S1. Vertically splice together multiple layers of septic tank bodies 11 to form a prefabricated septic tank 1, and then horizontally splice together multiple prefabricated septic tanks 1 to form a prefabricated septic tank 1. The upper and lower adjacent layers of septic tank bodies 11 are connected by tongue and groove. At the same time, the first splicing seams of the upper and lower adjacent layers of septic tank bodies 11 are filled with epoxy resin mortar 2, and the second splicing seams of the upper openings of the two left and right adjacent prefabricated septic tanks 1 are filled with epoxy resin mortar 2.

[0038] S2. A cast-in-place base 3 for installing a pool cover is formed by casting at the upper opening of the prefabricated septic tank 1. The cast-in-place base 3 is arranged in a circle along the circumferential direction of the upper opening of the prefabricated septic tank 1 so that the upper part of the water-stop steel plate 12 is buried in the cast-in-place base 3.

[0039] The medical-grade anti-leakage septic tank structure of the present invention adopts a prefabricated septic tank as the main body, and is attached to a cast-in-place base to install a concrete tank cover, thereby saving construction time while ensuring the excellent anti-leakage effect of the finished septic tank.

[0040] At the vertical joints (first joints) of the prefabricated septic tank, convex grooves (tongue and groove) are set. Structurally, by optimizing the bite method and increasing the bite area to improve stability, mutual leakage on both sides of the tank wall is avoided, and epoxy resin mortar is used for consolidation at the tongue and groove. Compared with waterproof mortar, epoxy resin mortar has higher bonding force and higher compressive strength, and the thermal expansion coefficient of epoxy resin mortar is close to that of concrete. It is not easy to detach from the bonded substrate and has good durability. More importantly, epoxy resin mortar has stable chemical properties and good corrosion resistance. It has the properties of impermeability, frost resistance, salt resistance, alkali resistance, and weak acid corrosion resistance. In the presence of other chemical pollutants in the septic tank, it has better anti-leakage effect, greatly improving the service life of the septic tank.

[0041] At the same time, at the junction of the outer wall of the prefabricated septic tank and the cast-in-place base, the water-stop steel plate reserved when the prefabricated septic tank leaves the factory is connected to the cast-in-place base to ensure the anti-leakage effect at that location and reduce the risk of pollutants in the septic tank from leaking out.

[0042] At the transverse joint of the inner wall of the prefabricated septic tank (the second joint), the prefabricated septic tank here is reserved with a 200mm height and a water-stop steel plate for cast-in-place. First, use epoxy resin mortar to consolidate the joints as the first layer of protection. After consolidation, cast-in-place is carried out at the reserved position, and the cast-in-place concrete top part is combined with the prefabricated septic tank as a whole through the reserved water-stop steel plate of the prefabricated septic tank as the second layer of protection. Combining the convenience of the prefabricated septic tank with the stability of the cast-in-place structure, it effectively solves the problem of leakage between the joints of the prefabricated septic tanks.

[0043] The medical-grade anti-leakage septic tank structure of the present invention combines a cast-in-place concrete structure with a prefabricated septic tank, which not only saves construction time but also ensures the stability, integrity and extremely high anti-leakage effect of the septic tank.

[0044] The prefabricated septic tank joints of the medical-grade anti-leakage septic tank structure of the present invention innovatively use epoxy resin mortar instead of waterproof mortar. The epoxy resin mortar has higher bonding force, higher compressive strength, and more stable chemical properties, which greatly improves the anti-leakage performance of the septic tank and extends the service life of the septic tank.

[0045] The medical-grade anti-leakage septic tank structure of the present invention connects the prefabricated septic tank with the cast-in-place structure into a whole by reserving a water-stop steel plate on the prefabricated septic tank, thereby ensuring that no leakage will occur at the connection of the prefabricated septic tank.

[0046] The vertical joint structure of the prefabricated septic tank of the medical-grade anti-leakage septic tank structure of the present invention innovatively adopts a convex-shaped mother-and-child groove, which increases the bite area to improve the overall stability and uses epoxy resin mortar for consolidation, thereby effectively preventing mutual leakage on both sides of the tank wall.

[0047] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other.
