Ground source heat pump tube embedment method based on piling process

Abstract

The invention discloses a ground source heat pump tube embedment method based on a piling process. The ground source heat pump tube embedment method based on the piling process is characterized by comprising steps as below: forming piling holes by using a piling machine, wherein the inner diameter of the piling holes is larger than the outer diameter of a tubular pile; installing at least one hook at the position near the bottom of the outer surface of the tubular pile, preparing ground source heat pump tubes according to a preset length and a preset amount, fixing the ground source heat pump tubes on the hook, and fixing the ground source heat pump tubes on the tubular wall of the tubular tubes; hanging the tubular piles right above the piling holes in a perpendicular mode; putting the tubular piles into the piling holes, utilizing self weights of the tubular piles to enable the tubular tubes to sink, burying the ground source heat pump tubes underground through the traction of the hook, wherein the part, buried underground, of the ground source heat pump tubes is low in breaking risks, low in disturbance of the piling process of the tubular tubes, and therefore a plurality of ground source heat pump tubes can be buried at the same time under the condition permitted by engineering design.

Description

technical field [0001] The invention relates to a ground source heat pump pipe embedding method, in particular to a ground source heat pump pipe embedding method based on a pile planting process. Background technique [0002] Ground source heat pump technology is a means of using deep constant temperature geothermal energy as an energy source, and it is necessary to embed ground source heat pump pipes deep into the foundation. So far, the commonly used construction methods for embedding ground source heat pump pipes can be classified into the following three categories: [0003] First, use a drilling rig to drill a hole in the deep soil layer of the foundation according to the designed depth and then insert the ground source heat pump pipe. The ground source heat pump pipe is a flexible pipe body with relatively light weight. The intubation construction process is affected by the buoyancy of mud or groundwater, so artificial intubation is generally used. However, it is diff...

Problems solved by technology

The ground source heat pump tubes using this embedding method are not in sufficient contact with the soil layer, and the heat exchange performance is weak; since the pile top must be embedded in the concrete foundation for a certain length, the ground source heat pump tube cannot cross the pile top and then bend to the bottom of the concrete foundation. Therefore, it is necessary to cut through the pipe pile wall to bend the ground source heat pump pipe into the soil layer at the bottom of the foundation. This will not only trouble the construction, but also damage the structure of the pipe pile top and affect the bearing capacity of the pipe pile.
