Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A concrete tower cartridge assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-6.
Referring to fig. 1 to 6, a concrete tower cartridge assembly 100 according to an embodiment of the present invention includes: a first tower section 1, a second tower section 2 and a sealing ring 3.
The second tower section 2 is located above the first tower section 1, the first tower section 1 and the second tower section 2 are internally provided with through-height holes 101, each hole 101 is internally provided with a pre-stressed sleeve 102, the pre-stressed sleeves 102 are used for penetrating pre-stressed tendons, the upper end of each pre-stressed sleeve 102 is higher than the upper end of the corresponding hole 101, the lower end of each pre-stressed sleeve 102 is higher than the lower end of the corresponding hole 101 so that the hole 101 located at the lower part of the pre-stressed sleeve 102 forms a positioning groove 103, and the upper end of the pre-stressed sleeve 102 in the first tower section 1 is matched in the positioning groove 103 in the second tower section 2. From this, when hoisting second tower section of thick bamboo section 2 on first tower section of thick bamboo section 1, through with the cooperation of the upper end of prestressing sleeve 102 on first tower section of thick bamboo section 1 in the positioning groove 103 of second tower section of thick bamboo section 2, be convenient for accurate, the butt joint fast between prestressing sleeve 102 on the first tower section of thick bamboo section 1 and the prestressing sleeve 102 of second tower section of thick bamboo section 2, guarantee that later stage prestressing tendons wear to establish smoothly and can guarantee concrete tower section of thick bamboo subassembly 100's final shaping quality. Specifically, the prestressed tendons penetrate through the prestressed sleeve 102 located in the hole 101 of the first tower tube section 1 and the prestressed sleeve 102 located in the hole 101 of the second tower tube section 2 in the up-down direction, so that the connection strength between the first tower tube section 1 and the second tower tube section 2 is improved, and the structural strength and the stability of the whole concrete tower tube assembly 100 can be improved. Alternatively, the pre-stressed sleeve 102 may be a bellows.
The number of the duct 101 may be multiple, and multiple ducts 101 may be uniformly spaced along the circumferential direction of each tower section, and accordingly, the number of the prestressed sleeves 102 is the same as that of the ducts 101 and are disposed in the corresponding ducts 101. Thereby, the structural strength and stability of the concrete tower cartridge assembly 100 may be further improved.
It will be appreciated that by controlling the length of the pre-stressed sleeve 102 extending out of the first tower section 1 and the thickness of the adhesive layer 105, the height of the adhesive layer 105 which floods into the positioning groove 103 can be controlled to be lower than the upper end of the pre-stressed sleeve 102 which fits into the positioning groove 103, thereby avoiding the adhesive layer 105 from plugging the upper port of the pre-stressed sleeve 102.
In the concrete construction process, firstly, an adhesive layer 105 is arranged (by smearing) on the upper end face of a first tower cylinder section 1, a sealing ring 3 is connected on the lower end face of a second tower cylinder section 2, the sealing ring 3 can be connected on the lower end face of the second tower cylinder section 2 by bonding, fasteners or buckle structures and the like, then the second tower cylinder section 2 is hoisted to the first tower cylinder section 1, when the second tower cylinder section 2 faces to the lower part of the first tower cylinder section 1, the sealing ring 3 is contacted with the adhesive layer 105 on the upper end face of the first tower cylinder section 1 and is embedded into the adhesive layer 105, one part of the adhesive layer 105 is embedded into the sealing ring 3, the sealing ring 3 generates an annular constraint effect on the adhesive layer 105 which gushes into the sealing ring, the sealing ring is limited from extruding outwards along the radial direction, when the second tower cylinder section 2 is continuously lowered, the second tower cylinder section 2 extrudes the sealing ring 3, the adhesive layer 105 which gushes into the sealing ring 3 axially to a positioning groove 103 of the second tower cylinder section 2, the bonding layer 105 which is poured into the positioning groove 103 of the second tower section 2 fills the fit clearance between the prestressed sleeve 102 and the positioning groove 103, so that annular sealing is formed, and slurry is prevented from leaking out through the fit clearance between the prestressed sleeve 102 and the positioning groove 103 when grouting is carried out in the prestressed sleeve 102.
The sealing mode is an occlusion sealing of a transfer pressure-bearing surface, and during grouting operation, the acting surface of pressure in slurry is higher than a horizontal joint between a first tower cylinder section 1 and a second tower cylinder section 2, so that the action of the pressure in slurry fluid during grouting is converted into an up-and-down extrusion effect in the axial direction of a pore passage from the annular extrusion destructive effect of the horizontal direction between towers to a bonding layer. Under the working condition that the vertical prestress is applied to the tower barrel, the bearing capacity of grouting is higher. In short, this sealing configuration is achieved by hoop restraint, which causes the adhesive layer 105 to flow up into the positioning groove 103 of the second tower section 2, thereby eliminating the misalignment capability of the partially prestressed sleeve 102 and enhancing the sealing at the interface.
According to the concrete tower barrel assembly 100 provided by the embodiment of the invention, by arranging the sealing ring 3, when grouting is carried out towards the interior of the prestressed sleeve, the phenomenon of slurry leakage between two adjacent sections of tower barrel sections can be avoided.
It should be noted that the concrete tower barrel assembly 100 of the present invention is formed by connecting a plurality of tower barrel sections sequentially in an up-down direction, wherein the first tower barrel section 1 may refer to a tower barrel section located at a lower position of two adjacent tower barrel sections, and the second tower barrel section 2 may refer to a tower barrel section located at an upper position of two adjacent tower barrel sections. Alternatively, the tower segment may be formed by connecting a plurality of arc-shaped tower pieces, or the tower segment may be an integral annular tower piece.
Alternatively, as shown in fig. 3 to 5, the shape of the positioning groove 103 may be formed in a conical cylinder shape, and the cross section of the positioning groove 103 is gradually reduced in the direction from bottom to top. Therefore, the upper end of the prestressed sleeve 102 is convenient to be matched with the corresponding positioning groove 103, and the positioning speed and the matching speed can be improved.
In an alternative embodiment of the present invention, the sealing ring 3 is a rubber member, that is, the sealing ring 3 is made of a rubber material, and has high elasticity, good sealing effect and low cost.
In an optional embodiment of the present invention, the sealing ring 3 is a silicone member, that is, the sealing ring 3 is made of a silicone material, and has high elasticity, good sealing effect and low cost.

Further, as shown in fig. 3, 5 and 6, the groove-shaped opening 104 is directed toward the center of the seal ring 3, thereby making the sealing effect better.
In one embodiment of the present invention, the height of the seal ring 3 in the vertical direction is in the range of 15mm to 20mm, that is, the height of the seal ring 3 in the vertical direction is not less than 15mm at the minimum and not more than 20mm at the maximum, the height of the seal ring 3 in the vertical direction is not less than 15mm at the minimum, thereby ensuring high sealing performance of the seal ring 3, and the height of the seal ring 3 in the vertical direction is not more than 20mm at the maximum, thereby ensuring that the height of the seal ring 3 after being pressed is not more than 10mm, and further ensuring that the height of the horizontal joint between the first tower barrel section 1 and the second tower barrel section 2 is not more than 10mm, thereby ensuring the safety and reliability of the whole concrete tower barrel assembly 100.
