Problems solved by technology

However, the embedding method of binding the heat transfer tubes on the steel cage in the cast-in-place pile not only affects the concrete volume in the cast-in-place pile, but also increases the risk of the steel cage being corroded, thus affecting the bearing capacity and durability of the

Abstract

The invention discloses a construction method for embedding a pipe in a ground source heat pump pouring pile reinforcement cage. A steel pipe is used for substituting for a solid reinforcing steel bar as the main rib of a pouring pile reinforcement cage, and a heat transmission pipe is embedded in the steel pipe, as a result, problems caused by binding and embedding the heat transmission pipe and the reinforcement cage, including mutual interference, high probability of corrosion of a reinforcing steel bar, effect on overall bearing capacity of a pile foundation and the like, are solved. Compared with the traditional way of binding and embedding the heat transmission pipe and the reinforcement cage, the construction method is higher in survival rate of embedded pipe, compactedness of concrete is high, and embedment of the heat transmission pipe surely does not lower the overall bearing capacity of the pile foundation; compared with another traditional way of drilling and pipe embedding, the construction method greatly shortens construction period and saves underground space and engineering cost. The construction method is simple in construction process, strong in operability, convenient for quality control, and remarkable in economic benefit and heat transmission effect.

Description

[0001] technical field [0002] The invention relates to the technical field of pile buried pipes of ground source heat pump systems, in particular to a construction method for buried pipes in steel cages of ground source heat pump cast-in-situ piles. It is mainly applicable to the field of construction pile foundation and ground source heat pump technology. Background technique [0003] Ground source heat pump technology is a relatively stable temperature characteristic of underground soil, surface water, groundwater, etc., through the use of the earth as an energy storage body for heat exchange (store heat in the upper part of the ground in summer; transfer heat from the ground to the upper part in winter) The air-conditioning system of renewable energy in the building) replaces the traditional air-conditioning technology to achieve the purpose of energy saving and emission reduction. Buried heat exchangers underground is the construction difficulty and investment focus o...
