BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling pit having a telescope mechanism capable of following lift-up of a submerged pavement.

[0002]

[Prior Art and Problems to be Solved by the Invention]
When installing many refueling pits under the ground like an airport, if the refueling pit installation position is displaced due to temperature changes or ground fluctuations, the installation position and the refueling device in the refueling pit should be adjusted to correct this displacement. Tube) must be readjusted.

This readjustment is generally carried out by paving on a pavement formed on the ground and connecting a pipe at the upper part of the fueling device, or by digging out a fueling pit to readjust its installation position. However, there is a drawback that it is very troublesome.

The present invention solves such a drawback, and the ground fluctuation is very large, and a refueling pit having a mechanism for following up without deforming or breaking when lifting a submerged pavement surface is lifted. It is a proposal.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

The pit case 11 having the refueling device 10 inside is divided into upper and lower parts to form an upper case 12 and a lower case 13, and when the connecting portion of the upper case 12 and the lower case 13 comes into contact with water, the volume is increased. Providing an expanding water blocking material 16, the upper case 12 is embedded and fixed in the paving board 1'formed above the base board 1 "and divided into a predetermined size, and the lower case 13 is embedded and fixed in the base board 1". However, the present invention relates to a fueling pit having a telescopic mechanism characterized in that a lift-up portion 3 for lifting the pavement 1'is provided at an appropriate position on the pavement 1 '.

[0007]

When a large subsidence or depression occurs in the ground 1, for example, a lift-up jack a is connected to the lift-up section 3 of the pavement 1'to lift the pavement 1'to a predetermined height. Pit case 11 is divided into upper and lower parts, and the upper case
Since 12 is embedded and fixed in the pavement 1'and the lower case 13 is embedded in the base 1 ", the upper case 12 is pulled up with respect to the lower case 13 and the pit case 11 is extended.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show the case where a fueling pit according to the present invention is adopted on an airport runway, which will be described below.

One refueling pit including a refueling device 10 and a pit case 11 is provided in a section of the runway having a predetermined size.
The structure of the ground 1 for each section is divided into a pavement 1'and a foundation 1 ".

When the ground 1 of a certain section largely sinks, as shown in FIG. 3, a lift-up jack a is continuously provided to the lift-up portion 3 of the pavement 1'and the submerged pavement 1 '
Is raised to a predetermined height, the repair material 2 ′ is replenished in the gap 2 between the pavement 1 ′ and the foundation 1 ″, and the ground 1 is raised.

The lift-up portion 3 shown in the drawing has a jack mounting screw tube that is embedded in the pavement 1'in advance.

Reference numeral 4 is a joint screw cylinder, 5 is a hydraulic cylinder, and 6 is a hydraulic piston.

In working, the pedestal 7 is set in the jack mounting screw cylinder, the spacer 8 is inserted, and the hydraulic piston 6 is inserted.
Is contacted with the upper part of the spacer 8 and a large number of lift-up jacks a installed on the ground 1 of one section are simultaneously operated by hydraulic operation to check the degree of rise of the pavement 1'of the ground 1 with the pointer 9. Lift up to the desired height.

The upper case 12 is a tubular member having a locking flange 17 at the opening and a fitted portion 12 'formed at the lower part.
Reference numeral 13 is a tubular member having a small diameter portion 13 'formed on the upper portion thereof, and the fitting portion 12' of the upper case 12 is fitted into the small diameter portion 13 'via a space 14 having a space L. Water stop material 16 on the top and bottom
The filler 15 as an elastic member is disposed between the water stop members 16. The water blocking material 16 and the filling material 15 will be described in detail.

The waterproof material 16 in FIG. 1 is a double-lip type molded rubber. This rubber expands its volume when it comes into contact with water and has a reliable waterproofing effect. It prevents water from entering the pit case 11 from the ground 1 and lowers the upper case 12 and the lower case 13 when subsiding the ground or lifting it. It is possible to adapt to changes in the joining positions of both, such as misalignment and change in angle, and prevent the repair material 2'from entering the pit case 11.

The filling material 15 is an elastic sealing material made of sponge rubber in the shape of a square ring, and is fitted between the upper and lower water blocking materials 16 to adapt to the above-mentioned change and prevent the repair material 2'from entering.
Ensures waterproof effect.

FIG. 4 shows a state where the pavement board 1'is lifted up by the lift-up jack a. The pavement board 1'and the base board 1 "are separated from each other, but a new repair material 2'is provided in the gap 2 between them. The positions of both are maintained by packing (concrete mortar, etc.).

In the figure, reference numeral 18 is an opening / closing lid for lubrication, 19 is a pit case lid, 20 is a fixing bolt, 21 and 22 are rib plates and locking rods that lock the upper case 12 to the pavement 1 ', and 23 are connected. Chain, 24 is a refueling valve part, 25 is a mounting base, 26 is an installation stabilizing board, 27 is a sealing material, 28
Is an oil supply riser pipe, 29 is an oil distribution pipe, and 30 is a receiver for receiving the pedestal 7.

[0019]

[Effects of the Invention] Since the present invention is constructed as described above, when the ground is submerged, the refueling device as well as the pit case is not deformed or damaged even if the section is raised by, for example, a lift-up jack. The refueling pit has a telescope mechanism that is excellent in practical use.
