Embodiment Construction

[0029] The design, manufacture and implementation of this flexible laying structure are illustrated below in conjunction with the accompanying drawings.

[0030] See attached figure 1 , with figure 2 , U-shaped pipe 2 made of polyethylene is buried in the foundation pile 1, and the horizontal header 4 penetrates the distance between several foundation piles 1 outside the foundation pile 1, and is perpendicular to the U-shaped pipe 2; the concrete enclosure box 5 Close to the side of the foundation pile 1, the flexible connection method between the vertical heat exchanger and the horizontal header in the soil source heat pump pile of the present invention mainly includes the following steps:

[0031] 1. Make the flexible elbow connecting the U-shaped pipe in the pile and the horizontal header 3. Polyethylene pipe is used, and the diameter is usually DN20~DN40; its function is: the arc-shaped flexible elbow can stretch Straight, thereby greatly reducing the tensile stress on ...

Abstract

The invention relates to a construction method of laying a vertical ground buried pipe heat exchanger of a soil source heat pump in a building foundation pile, in particular to a structural type of an educing pipe of the buried pipe heat exchanger in the foundation pile and the construction method thereof. A method for flexibly connecting the vertical heat exchanger of the soil source heat pump in the pile and a level header is characterized in that the method comprises the following steps: 1) a flexible elbow for connecting a U-shaped pipe in the pile and the level header is prepared; 2) an enclosing box to be covered on the outside of the flexible elbow is prepared; 3) one end of the flexible elbow segment is connected with the educing pipe of the U-shaped pipe; 4) the enclosing box is installed, and the other end of the flexible elbow extends out from a lateral hole of the enclosing box and is connected with a branch pipe leading to the level header. The construction method can prevent damages and the leakage of the pipeline of the buried pipe heat exchanger in the building pile from having a negative impact on the security of the operation.

Description

technical field [0001] The invention relates to a construction method for laying a vertical buried pipe heat exchanger of a soil source heat pump in a foundation pile of a building, in particular to a structure type and a construction method of an outlet pipe of the buried pipe heat exchanger in a foundation pile. Background technique [0002] Ground source heat pumps can be divided into: ground water source heat pump systems, surface water source heat pump systems and soil source heat pump systems, and soil source heat pump systems can be divided into two forms: horizontal buried pipes and vertical buried pipes. For vertical buried tube heat exchangers (i.e. U-shaped tubes), they can be divided into: buried tubes outside the building foundation base, buried tubes between building foundation piles, There are three arrangements of buried pipes in building foundation piles. [0003] At present, buried pipes are mostly used outside the foundation base of buildings, and the des...
