technical field

The utility model relates to the technical field of waterproofing, in particular to a ground source heat pump PE pipeline waterproof casing pierced through a concrete bottom plate.

Background technique

For the buried PE pipe of the ground source heat pump system, the temperature of the circulating water in the pipe varies widely, usually between 5°C and 45°C. This thermal expansion and contraction makes the original tight seal between the PE pipe and the conventional water-stop casing. If the state is damaged, it will cause water leakage and water seepage during operation.

Therefore, water seepage and leakage caused by thermal expansion and cold contraction of buried PE pipes in ground source heat pump systems has become an urgent problem to be solved by those skilled in the art.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-2, the utility model provides a technical solution: a ground source heat pump PE pipe waterproof casing that penetrates the concrete floor, including a PE pipe 2 and a waterproof assembly that is socketed with the PE pipe 2, the The waterproof assembly includes a steel plate 1, a reducing joint 3 and a steel pipe 4, the steel plate 1 is arranged on the outer wall of the steel pipe 4, the reducing joint 3 is arranged at both ends of the steel pipe 4, and the reducing joint 3 The inner cavity of the steel pipe 4 forms a filling space on the outer wall of the PE pipe 2, and waterproof cement 5 is filled in the filling space.

Specifically, as shown in FIG. 2 , the reducing joint 3 at the upper end of the steel pipe 4 is connected with an annular plug 8 , which can better connect the reducing joint 3 with the steel pipe 4 and increase tightness.

Specifically, the inner cavity of the ring plug 8 is provided with a spring 7, and one end of the spring 7 is connected to the inner bottom surface of the ring plug 8. One end of the spring 7 is provided with a waterproof gasket 6, and the waterproof gasket 6 is connected to the reducing joint 3, and the waterproof gasket 6 is a wedge-shaped washer made of waterproof plastic, and the waterproof gasket 6 improves the sealing between the reducing joint 3 and the PE pipe 2, and increases waterproof performance.

Specifically, the steel plate 1 is welded along the entire circumference of the outer diameter of the steel pipe 4, the thickness of the steel plate 1 is 10 mm, and the steel plate 1 is embedded in the wall 9 during initial installation to increase the stability of the waterproof assembly.

Specifically, the waterproof component is made of stainless steel.

The waterproof principle of the utility model is: the steel plate 1, the steel pipe 4 and its waterproof cement 5 seal the pressurized water source, and the waterproof performance can be ensured after the initial installation. There is a gap between 2 and waterproof cement 5.
