Embodiment Construction

[0020] The method for grouting and backfilling ground source wells proposed by the present invention will be further described in detail below in conjunction with specific examples. Advantages and features of the present invention will be apparent from the following description and claims.

[0021] The core idea of ​​the present invention is to provide a method of grouting and backfilling ground source wells, which uses the backfill slurry to backfill the part, then uses pebbles to seal cracks or faults, and then continues to backfill the ground source wells gradually. All the fissures and faults in the underground are sealed, and the grouting and backfilling work is completed, which solves the problem that the backfill slurry is easy to flow away due to the fissures or faults, and increases the grouting and backfilling work in the ground source well drilling construction. The efficiency is high, and the amount of backfill slurry is saved, which saves the cost.

Abstract

The invention provides a ground source well grouting backfill method. The method comprises the following steps: performing backfill by using backfill slurry, plugging cracks or faults by using pebbles, gradually plugging total cracks or faults in the ground source well by continuously using a backfill method through backfill slurry, and finishing the grouting backfill operation. The problem that the backfill slurry easily flows away due to the cracks or faults is well solved, the grouting backfill operation efficiency in ground source well digging construction is improved, the amount of the backfill slurry is saved, and the cost is saved.

Description

technical field [0001] The invention relates to a ground source buried pipe installation process, in particular to a ground source well grouting and backfilling method. Background technique [0002] Ground source heat pump is a high-efficiency energy-saving air conditioning system that uses shallow geothermal energy (referred to as ground energy) for both heating and cooling. Ground energy can be used as a heat source for ground source heat pump heating in winter, and can also be used as a cold source for ground source heat pump cooling in summer. In winter, the ground source heat pump takes out the heat in the ground energy by exchanging heat with the ground energy, and supplies indoor heating after raising the temperature; in summer, the ground source heat pump takes out the heat in the room by exchanging heat with the ground energy, released into the ground energy. [0003] The most important component of the ground source heat pump is the ground source buried pipe, whi...
