Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a cooling pipe for mass concrete. BACKGROUND

[0002] After the concrete pouring is completed, the concrete will generate a large amount of heat due to hydration reaction, and in general, water is sprinkled on the surface of the concrete to dissipate heat, however, for mass concrete, the heat inside is difficult to dissipate, the temperature difference between inside and outside is too large, and thus the mass concrete cracks, therefore, the mass concrete generally needs to be maintained for 3 to 7 days, the cooling pipe is arranged in the concrete during the concrete maintenance, and circulating water is fed into the cooling pipe to take away the heat in the concrete, but the existing cooling pipe still has the following deficiencies: 1. In order to maximize the contact area between the cooling pipe and the concrete, the cooling pipe is often arranged in a serpentine shape, and after the concrete maintenance is completed, the cooling pipe needs to be grouted to avoid hollow parts in the mass concrete, and the curved part makes it difficult to completely fill the grouting; 2. During cooling, the curved part increases the internal flow resistance and slows down the flow of circulating water, thereby affecting the cooling effect; 3. In order to improve the cooling effect, a thin-walled steel pipe is often used in actual construction, and the structural strength is poor, the cooling pipe bears various construction load pressures during the concrete pouring process, and is prone to deformation or damage, which seriously affects the flow of circulating water during the maintenance process. SUMMARY

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a cooling pipe for mass concrete, which has high structural strength and is beneficial to concrete grouting and cooling water flow.

[0004] The technical scheme adopted by the utility model is as follows:

[0005] A cooling pipe for mass concrete, comprising an outer pipe and an inner pipe, the outer pipe and the inner pipe are straight pipes, the inner pipe is arranged in the outer pipe, a support part is arranged between the inner pipe and the outer pipe, a flow channel is formed between the inner pipe and the outer pipe, and circulating water can flow through the flow channel; the support part is fixedly connected to the outer wall of the inner pipe, and the inner pipe can be pulled out after the concrete maintenance is completed.

[0006] Compared with the prior art, the utility model has the beneficial effects that:

[0007] 1. The outer pipe is a straight pipe, which has no curved part in the concrete, is beneficial to grouting of the cooling pipe after maintenance, and the flow of circulating water during cooling will not slow down, thereby ensuring the cooling effect;

[0008] 2. The double pipes are arranged, the inner pipe supports the outer pipe, and the overall structural strength is improved;

[0009] 3. After the concrete curing is finished, the cooling pipe no longer plays a role, and the adhesion between the cooling pipe and the concrete is strong, so the cooling pipe cannot be pulled out, therefore, the outer pipe and the inner pipe are separated, the inner pipe can be pulled out and recycled, and the cost is saved.

[0010] As a preferred embodiment of the utility model, the supporting part comprises a plurality of longitudinal reinforcing ribs, and the plurality of longitudinal reinforcing ribs are arranged annularly and spaced apart on the inner pipe.

[0011] Beneficial effect: the longitudinal reinforcing rib increases the structural strength of the inner pipe, and supports the inner wall of the outer pipe, thereby improving the structural strength of the outer pipe and the inner pipe as a whole, and making them less likely to deform.

[0012] As a preferred embodiment of the utility model, six longitudinal reinforcing ribs form a group, and a plurality of groups of longitudinal reinforcing ribs are arranged along the axial direction and are arranged alternately.

[0013] Beneficial effect: the plurality of groups of longitudinal reinforcing ribs arranged alternately make the supporting points of the inner pipe on the outer pipe more evenly distributed, and the stress on the inner pipe more evenly distributed.

[0014] As a preferred embodiment of the utility model, the outer pipe is provided with a connecting flange at both ends, and the connecting flange is provided with a plurality of mounting holes for mounting bolts.

[0015] Beneficial effect: the circulating water is generally pumped from the pool, flows to the corresponding outer pipe through the liquid inlet pipe, and then flows back to the pool through the liquid outlet pipe after heat dissipation, and the connecting flange is arranged to facilitate the connection of the outer pipe with the liquid inlet pipe and the liquid outlet pipe.

[0016] As a preferred embodiment of the utility model, the outer wall of the connecting flange is provided with a plugging plate, the plugging plate plugs the inner pipe, the plugging plate is annularly provided with a plurality of first through holes, and the first through holes are in communication with the flow channel.

[0017] Beneficial effect: the plugging plate is arranged to make the water in the liquid inlet pipe flow into the flow channel only, but not into the inner pipe, thereby reducing the space for the circulating water to flow, and thus the volume of the circulating water passing through the outer pipe per unit time is reduced, the flow rate of the circulating water is increased, the power required by the water pump is reduced, and thus the power consumption is reduced.

[0018] As a preferred embodiment of the utility model, the plugging plate is annularly provided with a plurality of second through holes, and the second through holes correspond one-to-one to the mounting holes.

[0019] Beneficial effect: the second through holes are arranged to make the bolts pass through the second through holes and the mounting holes when the connecting flange is installed, thereby synchronously assembling the connecting flange and the plugging plate, and making the assembly and disassembly more convenient.

[0020] As a preferred embodiment of the utility model, the plugging plate is made of an elastic plate.

[0021] Beneficial effect: when the bolt is tightened, the elastic plate is pressed to seal the gap of the connection, thereby ensuring the sealing. BRIEF DESCRIPTION OF DRAWINGS
