What are the special requirements for drilling technology of underground heat exchanger in ground source heat pump system?

The underground heat exchanger of ground source heat pump system is an important part of ground source heat pump and the most critical project in concealed engineering. Once leakage occurs after completion, it is very difficult to remedy it. Before drilling, sufficient preparation is needed to ensure the engineering quality. What to prepare specifically, we will explain one by one:

1. On-site inspection, this is very important; According to the garden environment, local geology and the size of the garden, choose the appropriate construction scheme. The drilling location should be considered to avoid underground facilities such as underground pipelines, rainwater, sewage pipelines, high and low voltage household lines and basements.

2. The heat exchange well spacing of ground source heat pump should be 4m; After the measurement is completed, the drilling position mark is initially set on site.

3. Before drilling, necessary protective measures should be taken for fences, green belts, fences and underground pipelines.

4. Drilling rig equipment and buried materials should be classified and stacked after entering the site, and pay attention to fire prevention, dustproof, waterproof and sun protection.

5. The rig equipment should be debugged before entering the site, and the drilling working hours should follow the property management regulations of the community to avoid disturbing people and being complained.

According to Zhu Rong's white paper on environmental ground source heat pump technology, there are many acceptance criteria for outdoor drilling and buried pipe engineering; It is precisely because of the strict control of details that Zhu Rong's environment can be better in quality and quality; It is suggested that the owner must choose a qualified and capable company like "Zhu Rong Environment" to design and construct the ground source heat pump system integrator to ensure the stability of the system.
