Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to a method for dividing construction joints in a water tank. Background Technology

[0002] Existing water tanks generally have complex shapes, high requirements for impermeability and precision, and large casting volumes, which can easily lead to risks such as cracking and leakage. Most reinforced concrete components are located in marine environments, which require high impermeability and corrosion resistance of materials. Marine water tanks have high impermeability requirements, with some tank walls reaching a thickness of 700mm. The heat of hydration during concrete casting is large, making it difficult to control concrete cracks. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a construction method for dividing construction joints in a water tank. This method reduces the risk of water tank cracking and leakage by rationally dividing construction joints and pouring in sections and layers, and by setting water-stop steel plates at each construction joint.

[0004] The technical solution adopted by this invention to solve its technical problem is: a construction method for dividing construction joints in a water tank, the method comprising the following steps:

[0005] Step S10: Set three vertical construction joints at the bottom of the pool to divide the bottom of the pool into a first area, a second area, and a third area; the pool consists of four sides, namely the first side, the second side, the third side, and the fourth side.

[0006] Step S20: Construct the bottom slab of the pool in the first area, construct the guide wall of the pool side wall to the upper part of the first floor lower archway, and then set the guide wall on the outer side wall of the second area.

[0008] Step S40: Construct the arched wall of the lower archway of the semi-circular tunnel in the second area up to the lower part of the vertical section of the arch beam, and then pour the lower part of the upper archway of the semi-circular tunnel of the outer wall section.

[0009] Step S50: The side walls of the pool on the second and fourth sides of the first area are poured, and a temporary holding pool is set at the side wall on the fourth side. A watertight door is set below the temporary holding pool, and the temporary holding pool is poured up to the top of the watertight door.

[0010] Step S60: Pour the second side wall of the first region and complete the second slab pouring at the second side wall; set an overflow trough on the semi-circular tunnel of the third side of the second region and pour the overflow trough to the bottom.

[0028] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0029] This invention discloses a construction method for dividing construction joints in a water tank, specifically comprising the following steps:

[0030] Step S10: Three vertical construction joints are set at the bottom of the pool, dividing the bottom of the pool into three areas to ensure the accuracy of the display window archway; the bottom of the pool is enclosed by four sides, such as... Figure 1 As shown, the four sides are defined as side 10, side 20, side 30, and side 40, respectively. The first construction joint extends from side 20 towards side 40, and the second construction joint extends from side 40 towards side 20. The first and second construction joints are connected and are on a straight line. The third construction joint extends from side 30 towards side 10 and connects with both the first and second construction joints. These three construction joints divide the bottom of the pool into three areas, as shown in the figure, defined as area 50, area 60, and area 70, respectively.

[0031] Construction was carried out in three areas in a continuous flow: 6 constructions were carried out in the first area (50), 8 constructions were carried out in the second area (60), and 4 constructions were carried out in the third area (70).

[0032] Step S20: Construct the bottom slab of the water tank in Zone 50, extending the guide wall of the water tank sidewall to the upper part of the first-floor lower archway, without exceeding the elevation. (Refer to...) Figure 2 In this embodiment, the elevation is +0.7m. The guide wall on the side wall of the pool is constructed to 200mm above the first-floor lower archway. Then, a 200mm guide wall is set on the outer wall of the second area 60, that is, a 200mm guide wall is set on the third side 30. Because a semi-circular tunnel needs to be set on the outer wall of the third side 30, and the height difference of the lower archway of the semi-circular tunnel is relatively large, it is difficult to ensure the accuracy of the lower archway in one construction. Setting a guide wall can ensure the accuracy of the lower archway.

[0033] Step S30: Construct the sidewalls in the first area 50, pouring the sidewalls up to the bottom of the first-floor archway on the second side 20 and the fourth side 40, at the same elevation. (Refer to...) Figure 3 As shown, in this embodiment, the sidewall is poured to +2.5m at the bottom of the upper archway of the first floor of the second side 20 and the fourth side 40. Then, a semi-circular tunnel is poured at the outer wall of the third side 30 in the second region 60; the archway of the semi-circular tunnel near the second side 20 is the lower archway, and the archway of the semi-circular tunnel near the fourth side 40 is the upper archway. First, the second region 60 is poured to 200mm above the lower archway of the semi-circular tunnel, and then the outer wall is constructed to the highest elevation of the lower archway. Subsequently, the sidewall of the pool in the third region 70 is poured to 200mm above the lower archway, completing the ramp construction of the semi-circular tunnel. The semi-circular tunnel is located at the outer wall of the third side 30, extending from the second side 20 to the fourth side 40, and the height of the semi-circular tunnel gradually increases from the second side 20 to the fourth side 40.

[0034] Step S40: Construct the arched wall of the lower archway of the semi-circular tunnel in the second area 60 up to the lower part of the vertical section of the arch beam, and then pour the lower part of the upper archway of the semi-circular tunnel of the outer wall section. (Refer to...) Figure 4 As shown, in this embodiment, an arc-shaped wall is first poured on the outer side wall of the semi-circular tunnel, extending 200mm below the vertical section of the arched beam. This arc-shaped wall extends from the lower archway on the second side 20 to the upper archway on the fourth side 40. Then, the outer wall section is poured to 200mm below the upper archway of the semi-circular tunnel.

[0035] Step S50: Refer to Figure 5 As shown, the sidewalls of the pools on the second side 20 and the fourth side 40 of the first area 50 are poured, reaching 200mm above the lower archway of the second layer, at an elevation of +5.5m. A temporary holding pool is set at the sidewall of the fourth side 40, with a watertight door below it. The temporary holding pool is poured to 200mm above the watertight door, at an elevation of +5.8m. Then, an arched beam 302 is poured at the archway of the third side 30 in the second area 60, reaching 450mm above the upper archway. The third side 30 in the third area 70 is also poured, with the pouring height the same as the temporary holding pool, at an elevation of +5.8m.

[0036] Step S60: Refer to Figure 6 As shown, the sidewall of the second side 20 in the first area 50 is poured to an elevation of +6.7m, and the second-layer slab is poured at the sidewall of the second side 50. Then, an overflow chute is set on the semi-circular tunnel of the third side 30 in the second area 60, and poured to 200mm above the bottom of the overflow chute, at an elevation of +6.7m, thus completing the pouring of the ramp.

[0037] Step S70: First, pour the concrete for the temporary holding tank located on the fourth side 40 of the first area 50, completing the pouring of the second-layer slab of the temporary holding tank, with an elevation of +7.9m. (Refer to...) Figure 7 As shown, the overflow channel in the second area 60 is then poured to an elevation of +7.8m. Then, the second-layer slab in the third side 30 of the third area 70 is poured to an elevation of +7.9m.

[0038] Step S80: Refer to Figure 8 As shown, first, the top of the first side 10 is poured, with the pouring length being the same as the length of the first side. Then, the top of the second side is poured, with the pouring length being the same as the length of the second side 20. Next, the overflow channel in the second region 60 is poured, with the pouring length being the same as the length of the overflow channel.

[0039] Step S90: Refer to Figure 9 As shown, the top slab of the entire water tank is poured, and the construction of the entire water tank is completed after the top slab is poured.

[0040] Reference Figures 10 to 16 In this design, due to the complex shape of the water tank and the high requirements for impermeability and precision, the overall volume of the tank is very large. Without proper construction joint division and segmented, layered pouring, risks such as cracking and leakage could occur. By rationally dividing the construction joints and using 316L water-stop steel plates at each joint to prevent leakage, and by adding 316L crack-resistant steel wire mesh to the reinforcing steel protective layer of the tank walls and bottom, the risks of cracking and leakage can be reduced.

[0041] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
