Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a water pipe device used for cooling large-volume concrete. Background Art

[0002] Mass concrete refers to large-volume concrete with a minimum geometric dimension of no less than 1m. Mass concrete has a small surface coefficient, concentrated hydration heat release, and rapid internal temperature rise. Due to the large temperature difference between the inside and outside, cracks are easily formed, which can seriously affect the safety of the structure. In order to cool it quickly and evenly, cooling measures such as layered pouring and buried water pipes are generally adopted; the buried water pipes in the prior art are extensive and do not take into account the thermodynamic significance of the direction of cooling water for the overall temperature transfer, so the crack control effect on mass concrete is not ideal. Summary of the invention

[0003] The utility model aims to overcome the above defects and provide a water pipe device for cooling large volume concrete.

[0004] The technical solution adopted by the utility model is as follows: a water pipe device for cooling large-volume concrete, characterized in that: a plurality of layers of water pipes are arranged in the height direction, each layer is composed of a plurality of drainage pipes, and the water pipes of adjacent rows are connected at one end or the other end thereof, thereby forming a multi-stage S-shaped waterway; a plurality of N-shaped pipe sections are arranged on each drainage pipe, thereby forming an upper convex point higher than the water pipe of the layer and a lower concave point lower than the water pipe of the layer; in the water pipes of adjacent layers, the projections of the lower concave points of the upper water pipes and the upper convex points of the lower water pipes on the plane coincide with each other.

[0005] It also includes a reinforcement device, which includes a base fixed on a pipe section connecting adjacent drainage pipes, and a top support threadedly connected to the base.

[0006] There are also several temperature measuring bases outside the water pipe for installing temperature sensors.

[0007] In the thermodynamic model of a large concrete block, the water pipe is a low temperature zone line, and since the flow rate in the water pipe is adjustable, it can be considered that the temperature is balanced at each point; while the heat release point and heat release time cannot be controlled or predicted, and can be considered random. The water pipe arrangement of the utility model is equivalent to cutting the entire concrete block into small blocks with a low temperature zone line, and through the design of the upper convex points and the lower concave points of the adjacent layers, there are points with significantly lower temperatures in the space, which is very important for the random heat release mode, so that each concentrated release of heat will not affect the small block area farther away, thereby having a better cooling effect. Therefore, the feature that the lower concave point of the upper water pipe and the upper convex point of the lower water pipe coincide with each other on the plane should not be understood mechanically. Even if there is a slight misalignment, as long as the two points are close enough to produce a point with a significantly lower temperature, it can play a better cooling role. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 4 is a top view of a single-layer water pipe in an embodiment.

[0009] Figure 2 It is a stereogram of a single-layer water pipe in the embodiment.

[0010] Figure 3 is a perspective view of a multi-layer water pipe in an embodiment.

[0011] Figure 4 is a schematic diagram of the reinforcement device. DETAILED DESCRIPTION

[0012] See also Figure 1 , Figure 2 , Figure 4 . The water pipe in this embodiment has a straight pipe section 1, a U-shaped pipe section 2 and an N-shaped pipe section 3. Several straight pipe sections and N-shaped pipe sections form a row, and two adjacent rows are connected by a U-shaped pipe section. In this embodiment, there are a total of six rows, marked as 10, 20, 30, 40, 50, and 60 respectively; five U-shaped pipe sections 2 connect adjacent rows at the left end or right end of each row to form a multi-level S shape. It should be noted that the U-shape and S-shape mentioned this time are described in the horizontal direction, that is, from a top-down perspective; and the N-shape is described from a vertical direction, that is, from a side-view perspective.

[0013] Each U-shaped pipe section has a base 4 fixed on the pipe section. The base 4 has an internal thread, so as to be connected to a jacking support 5 with an external thread, so that the jacking support can be telescopic relative to the base.

[0014] The N-shaped pipe section 3 connects two adjacent straight pipe sections 1 to form an upper convex point 31 and a lower concave point 32; when viewed from a side angle, the upper convex point 31 and the lower concave point 32 are respectively higher or lower than the layer of water pipes.

[0015] See also Figure 3 The figure shows two layers such as Figure 2 As shown in the figure, the water pipes are arranged up and down. As can be seen in the figure, the projections of the lower concave point 32 of the upper water pipe and the upper convex point 31 of the lower water pipe on the plane overlap and are very close to each other, so that a low temperature area can be formed between them.

[0016] In addition, a plurality of temperature measuring bases 6 are installed on the straight pipe section, which can be used to install temperature sensors.
