The first elastic member 42 and the second elastic member 53 are both springs.

Referring to fig. 2 and 3, since the water flowing through the fully-buried heating pipeline 10 during the heating process causes the horizontal movement of the fully-buried heating pipeline 10 and the fully-buried exhaust water drain assembly 20, the first displacement absorption assembly 60 is disposed outside the fully-buried vertical pipe 21.

The first displacement absorption member 60 includes a hollow first sleeve 61 and a hollow second sleeve 62 fitted over the first sleeve 61, and the first sleeve 61 and the second sleeve 62 are slidably connected. When the first displacement absorption member 60 is buried in the ground, the first sleeve 61 can be extended out of the second sleeve 62 so that the first sleeve 61 is flush with the ground in order to fit the height of the ground.

The first sleeve 61 of the first displacement absorption assembly 60 is used for being sleeved outside the fully-buried vertical pipe 21 and arranged at intervals, so that the second sleeve 62 and the fully-buried vertical pipe 21 are arranged at intervals, the interval between the two is used for filling the soft materials 1, such as sandy soil, the soft materials 1 can fill the whole height of the second sleeve 62, and also can only fill part of the first sleeve 61 and the lower part of the first sleeve 61, so that the soft materials 1 can be prevented from being interfered, and the fully-buried exhaust water drainage assembly 20 can be operated conveniently.

Example two

Referring to fig. 4 and 6, the second embodiment differs from the first embodiment in that the second embodiment uses a second displacement absorbent assembly 70 instead of the first displacement absorbent assembly 60 in the first embodiment.

The second displacement absorption assembly 70 comprises a third sleeve 71 and a fourth sleeve 72 sleeved on the third sleeve, wherein the third sleeve 71 and the fourth sleeve 72 are hollow, at least one anti-rotation plate 711 is arranged on the outer wall of the third sleeve 71, the anti-rotation plate 711 and the inner wall of the fourth sleeve 72 are arranged at intervals, and the outer wall of the third sleeve 71, which is not provided with the anti-rotation plate 711, and the inner wall of the fourth sleeve 72 are also arranged at intervals.

The third sleeve 71 of the second displacement absorption assembly 70 is used for being sleeved on the upper portion of the fully-buried vertical pipe 21, one end of the third sleeve 71 is clamped with the outer wall of the fully-buried vertical pipe 21, and an interval is formed between the fourth sleeve 72 and the portion, not sleeved with the third sleeve 71, of the fully-buried vertical pipe 21. Wherein the self-sealing male portion 40 is hidden from view on the air passage 321 on the second flange 32 in fig. 6.

The second cover 712 is arranged on the top of the third sleeve 71, the second cover 712 is connected with the second frame on the top of the fourth sleeve 72 through a plurality of circular rings 2 which can be partially overlapped and have a diameter which is enlarged from inside to outside, the second cover 712 can move along with the third sleeve 71, and the soft substance 1 cannot be seen when the second cover 712 is opened.

When the third sleeve 71 is not moved, the edge of the second cover 712 is overlapped on the ring 2 with the smallest diameter, but because a plurality of stacked rings 2 are provided, when the third sleeve 71 is moved, the rings 2 are displaced to a certain extent, so that no gap appears at the top of the fourth sleeve 72.

Certainly, in order to avoid the overlong arrangement of the fourth sleeve 72, an expansion sleeve 3 may be arranged at the lower portion, the expansion sleeve 3 is sleeved on the all-directly-buried vertical pipe 21, the expansion sleeve 3 and the all-directly-buried vertical pipe are not in contact, the soft substance 1 is filled between the expansion sleeve 3 and the all-directly-buried vertical pipe, and the lower portion of the fourth sleeve 72 is sleeved on the upper portion of the expansion sleeve 3.

In order to adapt to the height of the ground, when the fourth sleeve 72 is just buried underground, the top of the fourth sleeve can be higher than the ground, and then the raised part is cut according to the situation, so that the extending sleeve is not needed. Under the condition that the structure of the full-direct-burried vertical pipe 21 is not changed, the third sleeve 71 with the anti-rotation plate 711 is additionally arranged in the second embodiment, when the interval is filled, the friction between the full-direct-burried vertical pipe 21 and the soft substance 1 can be increased, and the rotation can be reduced.

When the fully-direct-buried heat supply pipeline 10 is heated to generate axial deformation and displacement, soft materials 1 are filled in the space between the fourth sleeve 72 and the third sleeve 71, the space between the fourth sleeve 72 and the fully-direct-buried vertical pipe 21 and the space between the telescopic sleeve 3 and the fully-direct-buried vertical pipe 21, and then a preset displacement compensation is formed in advance, and also a preset stress compensation is realized, the fully-direct-buried exhaust water drainage component 20 can move horizontally and synchronously, the stress damage of soil lateral counter force to the fully-direct-buried exhaust water drainage component 20 during translation is reduced, certainly, the soft materials 1 do not need to be filled, and the space can also be used as a displacement compensation. To reduce the possibility of loose material 1 entering the all-in-one vertical pipe 21, the top thereof may be plugged. Since the soft material 1 is located outside the third sleeve 71, it does not interfere with the operation of the all-in-one exhaust drain assembly 20, so the height of the soft material 1 may be the same as that of the all-in-one exhaust drain assembly 20, or may be lower than the top of the all-in-one exhaust drain assembly 20.
