Description
Technical Field
The utility model relates to an energy stake system.
Background
The ground source heat pump is one of new energy-saving and emission-reducing technologies of buildings which are mainly popularized and applied in China; the device is a device for performing heat and cold exchange by using the underground buried pipe heat exchanger and the underground shallow layer (< 200 m) geothermal resource of the earth, and realizes double effects of heating in winter and cooling in summer. However, the initial investment cost of the ground source heat pump system is relatively high due to the work of drilling and embedding the heat exchanger, and the like, so that the popularization and the application of the ground source heat pump system are limited. Therefore, the technical scheme for reducing the drilling construction cost of the buried pipe is the direction for engineering technicians to strive, and is also a necessary condition for widely popularizing and applying the ground source heat pump technology.
The technical scheme of the energy pile for embedding the heat transfer pipe in the engineering pile foundation so as to avoid the extra drilling construction cost of the embedded heat transfer pipe is the direction of the engineering technicians in recent years; and how to embed the heat transfer pipe in the pile foundation is a key factor of the technical scheme. In the prior art of the present invention, the 'underground energy collecting pile' (No. 200420055254.5) of the chinese utility model discloses a pile foundation form in which a U-shaped pipe is arranged in a concrete pipe pile, and a concrete core filling cover arranged at the upper end of the concrete pipe pile is penetrated out from the upper end of the U-shaped pipe, so as to embed a heat transfer pipe in a pile cavity after the completion of the driving of a precast tubular pile. The technical scheme is that the heat transfer pipe is embedded and the precast tubular pile is arranged in two construction steps, and the workload is increased compared with a one-step pile forming technology; meanwhile, the technology is not suitable for the pile body form with insufficient internal cavities such as a concrete prefabricated solid pile and the like, the form of the heat transfer pipe is also restricted in the space of the tubular pile core, and the soil body in the tubular pile core has a restriction influence on the depth of the buried heat transfer pipe. The Chinese utility model 'bored concrete pile with ground source heat pump PE pipe' (patent number: 201020109137.8) discloses a method for binding U-shaped PE pipe on bored concrete pile reinforcement cage, which makes bored concrete pile not only bear upper load, but also embed heat transfer pipe. According to the technical scheme, the U-shaped heat transfer pipe is bound on the cast-in-place pile reinforcement cage, so that the field workload is increased, and the construction period is prolonged; the U-shaped pipe bound on the reinforcement cage is easy to damage in the process of sinking into a drill hole or vibrating and pouring concrete, and is difficult to repair secondarily.
Relevant researches show that the heat transfer pipe is arranged after the precast pile is driven, or the heat transfer pipe is bound on a cast-in-place pile reinforcement cage and then the cast-in-place pile reinforcement cage is sunk into a drill hole, so that the workload is increased, the construction period is greatly influenced, and the popularization and the application of the cast-in-place pile reinforcement cage are limited to a certain extent.
