Description

Technical Field

[0001] The utility model relates to the field of building concrete construction, in particular to a direct insertion type unidirectional internal circulation cooling pipe device applicable to concrete pouring. Background Technique

[0002] In building construction, during the pouring of mass concrete, the cooling circulating water of the cooling pipe plays a crucial role in controlling the cracks of the concrete. The mass concrete structure is extremely prone to temperature cracks under the action of hydration heat. Embedding cooling pipes, as one of the common technical measures for controlling cracks in mass concrete, has a relatively wide application in actual projects. Its principle is mainly to take away a part of the heat inside the structure through the cooling water flowing inside the water pipe, reduce the peak temperature value of the structure, and reduce the temperature stress caused by temperature changes in the structure, so as to achieve the control of cracks in mass concrete. The main means is the U-shaped circulating cooling pipe, which is set back by embedding a φ51mm acoustic detection pipe in the concrete structure, 50cm away from the concrete surface, and spirally arranged at intervals of 80cm in a U-shape, with circulating water flow to take away the hydration heat temperature.

[0003] The above device has the following disadvantages: (1) The overall U-shaped circulation setting has great laying difficulty and high technical requirements; (2) The overall suspended setting requires separate additional fixing steel bars, increasing the material input; (3) The overall is a thin-walled acoustic detection pipe, which is prone to side leakage, and it is easy for cement-based materials to enter and block the acoustic detection pipe. The self-flowing water cannot achieve the cooling effect of the circulating water on the hydration heat of the concrete, cannot take away the excess heat, and cannot achieve the existing goal (crack control). Summary of the Invention

[0004] The utility model solves the problems of the existing cooling pipe being not installed and fixed in place, difficult to install, the installation spacing being easily offset due to the scouring of the poured concrete, and being prone to side leakage and blockage of the cooling pipe, and provides a direct insertion type unidirectional internal circulation cooling pipe device applicable to concrete pouring.

[0005] The utility model is realized by the following technical solutions: A direct insertion type unidirectional internal circulation cooling pipe device applicable to concrete pouring includes a main pipe and multiple branch pipes. The remaining branch pipes except the last branch pipe are all connected to the main pipe through three-way joints, and the last branch pipe is connected to the main pipe through an adapter joint. The end of each branch pipe is wedge-shaped, and the end of each branch pipe is inserted into a corresponding thin-walled steel pipe. Moreover, an anti-collision interval layer is sleeved on the outer periphery of each branch pipe at the positions where 1 / 3 and 2 / 3 of the inserted length from its end are located, and the branch pipe is clamped and installed in the thin-walled steel pipe through the anti-collision interval layer; the bottom end of the thin-walled steel pipe is sealed by a sealing component.

[0006] A direct-insert type one-way internal circulation cooling pipe device applicable to concrete pouring designed by the utility model includes a main pipe and multiple branch pipes. The main pipe is used to supply cooling water to each branch pipe. The remaining branch pipes except the last one are connected to the main pipe through three-way joints, and the last branch pipe is connected to the main pipe through an adapter joint. During the actual operation process, the thin-walled steel pipe is fixed in the pier cage and concrete pouring is carried out to avoid bending. The end of each branch pipe is wedge-shaped. The wedge shape is mainly to increase the opening of the pipe, and it is easier for water to flow into the thin-walled steel pipe through this opening. At the same time, the end of each branch pipe is inserted into a corresponding thin-walled steel pipe, and an anti-collision interval layer is sleeved on the outer periphery of each branch pipe at the positions of 1 / 3 and 2 / 3 of the inserted length from its end. The branch pipe is clamped and installed in the thin-walled steel pipe through the anti-collision interval layer; the anti-collision interval layer plays a buffering role when placing the branch pipe, avoiding the fracture of the branch pipe caused by strong friction, and can also squeeze and limit the flow of tap water to a certain extent, so as to fully contact with the cooling pipe and take away the hydration heat to the greatest extent. The bottom end of the thin-walled steel pipe is sealed by a sealing component. The distance between adjacent branch pipes is determined according to the actual use requirements. After being fixed at equal intervals, the position of the three-way connection port on the main pipe is determined, so as to match the distance of multiple branch pipes.

After that, water flows out from the main pipe, flows into the thin-walled steel pipe through the branch pipe, the water source enters the concrete through the branch pipe, and at the same time flows out through the bottom wedge opening. The circulating water enters through the branch pipe, flows out through the wedge opening and enters the thin-walled steel pipe, and finally overflows from the outlet of the thin-walled steel pipe, taking away the hydration heat during the concrete solidification process.

[0008] Preferably, the water inlet of the main pipe is connected to a water flow meter, and a connecting ball valve is also arranged at the water inlet end; the main pipe is supplied with water by a water pump.

[0012] Preferably, the outer diameter of the anti-wall-collision spacer layer is within 45 mm.

[0013] Preferably, both the anti-wall-collision spacer layer and the plugging component are made of multiple elastic adhesive tape layers.

[0014] Preferably, each branch pipe is divided into two sections. The first section pipe is located at the end of the branch pipe, and the second section pipe is connected to the main pipe. The first section pipe and the second section pipe are connected into one body through a butt sleeve joint.

Moreover, an anti-wall-collision spacer layer is sleeved on the outer periphery of each first section pipe at the positions of 1 / 3 and 2 / 3 of its length from the end. The first section pipe is clamped and installed in the thin-walled steel pipe through the anti-wall-collision spacer layer, and the second section pipe is connected to the main pipe.
