地源热泵中央空调系统地埋管施工技术

近几年，我国地源热泵中央空调系统建设发展迅速，基本上以每年20%～25%的速度在增长，该技术具有显著节能、舒适环保、零空气污染、安全、性能稳定、清洁、使用灵活、经济有效等特点。为节约用地，地源热泵空调地埋管系统常设置在建筑物基础底板下。因此，垂直地埋管管井、地埋管、水平地埋管组成的整个地埋管系统全部位于基础底板以下。底板施工后，地埋管系统无法观察，成为永久性工程。本文重点探讨了地埋管施工技术方面的问题。

The Buried Pipe Construction Technology of Ground Source Heat Pump Central Air Conditioning System

In recent years, the construction of Chinese ground source heat pump central air conditioning system developed rapidly, basically an annual 20% to 25% rate of growth. The technology has the features of energy efficiency significantly, comfort and environmental protection, zero air pollution, safety, performance and stability, cleaning, use flexible, and cost-effective. To save space, the ground source heat pump ground heat systems oflen set up under the foundation slab of the building. Therefore, the vertical ground heat tube wells, buried pipe, and horizontal ground heat pipe systems are entirely composed are all located in the foundatiort slab. Afler floor construction, the buried pipe systems cannot be observed, and become permanent works. This article focuses on the construction techuical issues of the buried pipe.
