Therefore, the side pipe penetrating structure basically realizes the entrance of the ground source pipe into the garage. However, the side-piercing structure has the following defects in the concrete construction: 1. after the construction of the ground reservoir structure is completed, subsequent constructions such as soil reclamation and the like can be carried out due to the pipe penetrating construction of the ground source and the complete sedimentation of the backfilled sand, and the construction period is prolonged by about 4 months; 2. the pipe penetrating construction of the ground source pipe needs to be carried out outside a ground reservoir, the operation space needs to be more than or equal to 2m, the slope releasing distance is large under the common height of the ground reservoir of about 5m, the influence on the red line range of a project is large, a large amount of sand needs to be backfilled, and the cost is high; 3. the biggest problem is that sandy soil is still not dense enough after long-time settlement, and settlement still easily causes the ground source pipe to be folded and flat after years, so that the ground source pipe is damaged, and the ground source pipe has to be closed due to water leakage of the system pipe, so that cold and heat source supply of a ground source heat pump system is influenced finally; 4. the ground source pipe is folded and flattened, and meanwhile, a gap is easily formed in the ground source sleeve in a plugging mode, so that underground water on the outer side of the ground reservoir leaks into the ground reservoir.
