Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
A kind of ground buried pipe of ground source heat pump system using foundation ditch region, including bottom plate and underground pipe, the underground pipe are built-in
There is heat transfer medium, bottom plate is located in foundation ditch, and underground pipe is located at below bottom plate, and underground pipe includes horizontal underground pipe and level is buried certainly
The vertical underground pipe that pipe extends downwardly；Specifically, vertical underground pipe includes feed pipe, and the backwater communicated with the feed pipe
Pipe, horizontal underground pipe communicate with feed pipe and return pipe.Feed pipe is connected with below return pipe by U-shaped top guide, and is formed U-shaped
Vertical underground pipe.There is the fine sand soil layer set gradually from top to bottom, protection sand bed and neonychium sand bed, the water below bottom plate
Level land pipe laying is located at below the fine sand soil layer.
The construction technology step of above-mentioned buried guard system includes：
（1）Land leveling, line distribution and set location are determined according to construction requirement.
（2）Vertically well bore, and the mud drilled out is transported., can on construction ground simultaneously in well bore
More bench drill machines while hole of digging a well are set, are so capable of the construction period of shortening vertical punching.
（3）Vertical underground pipe is installed.Vertical underground pipe may be damaged during due to later stage excavation pit, it is vertical in order to monitor
Whether straight underground pipe is destroyed, and feed pipe and return pipe is set into different length, and longer feed pipe or return pipe are connected with
Pressure gauge and length is not less than level ground（Or horizontal road construction road surface, depth are 0 meter）.As shown in figure 1, enter in the present embodiment
Length of pipe is more than backwater length of tube, and specially oral siphon length is about 113 meters, and backwater length of tube is about 101 meters, and wellhole is deep
