Problems solved by technology

This kind of construction technology has many construction procedures and slow construction speed, and the heat exchange tubes tend to be in an irregular state during the installation process, and the heat exchange tubes are easy to stick together, and even partially squeezed. In this way, during the heat exchange process, Heat transfer between tubes occurs, resulting in reduced heat transfer effect of heat exchange tubes

Embodiment Construction

[0020] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, in the construction process of the direct circulation buried pipe construction process, a telescopic drill bit 1 with a variable diameter and a heat exchange tube base 2 are firstly installed. Pass the telescopic drill bit 1 through the heat exchange tube base 2, connect the heat exchange tube 3 with the heat exchange tube base 2, and connect the telescopic drill bit 1 with the drill rod.

[0022] Such as image 3 As shown, the telescopic drill bit 1 includes a central shaft 15, the upper end of the central shaft 15 is provided with a sliding ring device 13, the sliding ring device 13 is sleeved on the central shaft 15 and is slidably connected with the central shaft 15, and the sliding ring device 13 is provided with a The fixed pin 14 can fix the fixed sliding ring device 13 on the central shaft. Sliding...

Abstract

The invention discloses a positive circulation direct-entry buried pipe construction technology, which can lower the heat exchange pipe together with the drill pipe into the drill hole when drilling. This construction process can lower the heat exchange tubes while drilling, integrate multiple processes together, reduce the process of sweeping holes, emptying and placing heat exchange tubes, and drill pipes for secondary lowering, which greatly improves the construction rate , the construction time can be shortened by about half; at the same time, the construction process can make the heat exchange tube close to the hole wall, avoiding the heat exchange tube being close or twisted together in the conventional buried pipe method, and improving the continuity and compactness of the filler , Compared with the conventional construction method, the heat exchange efficiency of the heat exchange system is greatly improved.

Description

technical field [0001] The invention relates to a pipe-burying process, in particular to a pipe-burying construction process of heat exchange pipes during installation of a ground source heat pump air conditioner. Background technique [0002] Ground source heat pump air conditioner is a new type of energy-saving and environmentally friendly air conditioner, which can make full use of the huge energy stored in the soil and lakes, recycle and regenerate, realize heating and cooling of buildings, and have low operating costs. The cold and heat source of this ground source heat pump air conditioner adopts a flexible and easy-to-control buried-pipe soil-source heat pump system. The circulating flow between the heat exchange tube and the heat pump unit realizes the heat exchange between the heat pump unit and the earth soil. [0003] During the installation process of the ground source heat pump air conditioner, it is necessary to drill heat exchange holes on the ground to bury ...
