Abstract

The invention belongs to the technical field of building construction, and particularly relates to a pipe clamp suitable for double U-shaped buried pipes and a pipe clamp module with a backfill material. According to the invention, the technical problems of unreasonable design and the like of the prior art are solved. The pipe clamp suitable for the double U-shaped buried pipes comprises a body, wherein the body is in a shape of a block, four spacing holes which are uniformly distributed and can keep the distance between the double U-shaped buried pipes are formed in the body, and a backfill space used for filling the backfill material is formed on the body. The pipe clamp module, which is formed by the pipe clamp suitable for the double U-shaped buried pipes, is suitable for the double U-shaped buried pipes and is provided with the backfill material. The pipe clamp is characterized in that the backfill space is filled with the backfill material. Compared with the prior art, the pipe clamp has the advantages of reasonable design, simplicity in operation and good backfill effect. The distance between the double U-shaped buried pipes can be kept, and a pipe distance short circuit of the double U-shaped buried pipes is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to buried pipe construction of a ground source heat pump system, in particular to a pipe clip suitable for double U-shaped buried pipes and a pipe clip module with backfill. Background technique [0002] In the double U-shaped ground source project, due to the deep depth of the buried hole, the position and spacing of the heat pipes in the buried hole cannot be well controlled within the design range, which makes it difficult to meet the design requirements for the heat transfer effect. The heat transfer effect of the heat pipe directly determines the operation effect of the buried pipe ground source heat pump system. The heat transfer pipe directly exchanges heat with the ground source side. There are generally two methods of backfilling the heat transfer pipe with manual backfilling and mechanical backfilling; among them, manual backfilling is generally backfilling the...

AI Technical Summary

Problems solved by technology

The heat transfer pipe directly exchanges heat with the ground source side. There are generally two methods of backfilling the heat transfer pipe with manual backfilling and mechanical backfilling; among them, manual backfilling is generally backfilling the slurry from the upper part, and this filling method often leads to poor filling density of the slurry. ;Mechanical backfilling requires special feeding pipes and mud pumps to backfill from the bottom, which is difficult to construct and the filling density of the slurry is not ideal

However, in the existing technology, generally, several special pipe clips are used to fasten the heat pipes together first, and then inserted into the buried hole. The disadvantage of this method is that when the backfill slurry is close to the special pipe clips, due The special tube clamp will block the slurry, and there will be poor filling density of the slurry, and it is difficult to install the tube. Because the filling effect cannot be observed under the buried hole, sometimes it will be blocked, and a tube interval short circuit will be formed between the heat transfer tubes, which directly affects Operation effect of buried pipe ground source heat pump system

[0004] The above scheme improves the existing technology to a certain extent by placing mechanical backfill pipes in the middle circular hole for backfilling, but due to the deep buried holes, the distance and position between the heat pipes cannot use this ground source. Heat pump system vertical heat exchanger tube stuck is completely solved

In addition, the pipe clamps in the above scheme are fixed on the buried pipe, and the backfilling is carried out through the backfill pipe. This grouting method is prone to blockage and short circuit between pipe intervals, and the filling density of the slurry is poor, which directly affects the performance of the buried pipe ground source heat pump system. running result
