Problems solved by technology

The disadvantages of these tubular heat exchangers based on excavation and burial are: high excavation costs, sometimes deep excavation is required in order to obtain a stable constant temperature layer, the site area to be excavated is large, and procedures such as laying tubular heat exchangers on site are required. Affect construction efficiency

Embodiment Construction

[0020] In the embodiment shown in Fig. 1, there is the shallow geothermal energy conversion anchor rod (2) of steel tie rod (1), and the length of its steel tie rod (1) is approximately equal to the length of the anchor rod, and consists of anchoring section (3) and free section ( 4) Add up to get. There are many regulations on the diameter and inclination of the anchor rod. During the production process of the whole anchor rod, the U-shaped pipe (5) of high-strength polyethylene or PVC or PPR material is bound and fixed when the steel tie rod (1) is made, and the length of the U-shaped pipe (5) is equal to that of the steel tie rod ( 1) It is long, and spacers (6) and expansion pieces (7) are arranged at certain intervals. And with the steel tie rod (1) and the grouting pipe (8), put it into the borehole, set the sleeve pipe (10) on the free section (4) on the grouting device (9), after anchoring, the U-shaped pipe (5 ) is buried in the anchor rod (2), and filled with therm...

Abstract

An anchor rod for the shallow geothermal energy conversion can convert the shallow geothermal energy and acts as both an anchor rod and a horizontally-embedded heat exchanger of a ground source heat pump, while having the anti-pull and earth retaining and supporting function by embedding a U-shaped coil heat exchanger in the anchor rod. A pull rod (steel rod, steel pipe, steel tendon, steel strand, and so on) or a grouting pipe binds and fixes the U-shaped coil in the anchor rod. According to the normal construction sequence, holes are made, a bound body of the pull rod and the coil heat exchanger as well as a grouting anchored body is arranged, and heat-conductive backfill materials are added into a free-section sleeve. The U-shaped coil in the anchor rod is connected with a ground surface pipe which is filled with the exchanging fluid. Through the heat exchange between the exchanging fluid in the U-shaped coil system and gravel materials in an anchoring section and the free section, and the shallow stratum, a geothermal exchange and circulating system of a horizontally embedded pipe of the ground source heat pump is formed.

Description

Technical field: [0001] The present invention relates to a kind of anchor rod which uses the anchor body of the anchor rod to embed a tubular heat exchanger device to convert low-temperature geothermal energy. Functional anchor. Background technique: [0002] At present, the known anchor rod is usually composed of anchor head, anchor head cushion, support structure, borehole, protective sleeve, pull rod (reinforced steel bar, steel pipe, steel wire bundle, steel strand, etc.), anchor body, anchor base plate (sometimes without ) and other components. The anchor rod is divided into a free section and an anchored section according to the active sliding surface. Anchor bolt technology pervades many aspects of the field of civil engineering, such as retaining support for slopes and foundation pits, and tensile and uplift foundations for towering structures or suspension buildings. But there is no function of using shallow geothermal heat, which ignores the heat exchange functi...
