Description

[Detailed description of the invention] (Industrial application field) The invention can be used, for example, in garages, factories, warehouses,
This relates to basements built on the ground where people and cars pass through, such as stores and terraces.

(Prior art) Basements are usually installed under buildings above ground.
For effective land use, basements are sometimes built on the ground where people and cars pass. An example of this is a conventional basement shown in FIG. 3 of Japanese Utility Model Application Publication No. 59-79742. This basement is constructed by digging a hole in the ground, inserting a container into the hole, positioning the top surface of the container on substantially the same horizontal plane as the ground, and placing side concrete 9 on the outside of the container in the hole. Door 2 on ceiling 5
1 is provided with a box-shaped entrance/exit 18.

(Problems to be Solved by the Invention) According to the above conventional configuration, the box-shaped entrance 18 is provided above the ground, which obstructs the passage of people and vehicles.

Therefore, there is a technique described in Japanese Utility Model Publication No. 11973/1983 as a technique for reducing the portion of the basement that protrudes above the ground. This is to close an entrance/exit formed on the top surface of the container 5 with a door 9. However, even with this, in order to prevent rainwater etc. from entering the container 5,
Since a frame 4 is provided around the entrance and the door 9 is placed over the frame 4, the door 9 is one step higher than the ground. For this reason, people are likely to trip over the door 9, and when a car, forklift, handcart, etc. is running, the wheels may ride up on the door 9.
It gets in the way of driving.

The inventor poured concrete on the ceiling excluding the entrance and exit of the container, provided a door covering the entrance and exit,
It has been found that by positioning the top surface of the door substantially on the same horizontal plane as the top surface of the concrete, it is possible to prevent it from interfering with the passage of people and vehicles. In addition, by forming a groove around the doorway, rainwater that has entered the gap between the door and the concrete is collected in the groove, preventing rainwater from entering the container through the doorway. I found out that it is possible. The present invention is based on this knowledge.

(Means for solving the problem) In order to solve the above problem, the basement of the present invention
A container with a bottom, side walls, and ceiling, and an entrance on the ceiling is inserted into a hole dug in the ground, backfilled with soil on the outside of the container in the hole, and a groove is formed around the entrance. Concrete is poured on top of the ceiling and backfill soil excluding the ditch, and a door is provided to cover the entrance/exit and the ditch, and the top surface of the door and the top surface of the concrete are located on substantially the same horizontal plane. .

(Function) In the above configuration, when the doorway is blocked by the door, the upper surface of the door and the upper surface of the concrete are substantially located on the same horizontal plane, so there is no risk of a person tripping over the door. Even when a car, a forklift, a handcart, etc. is run, the wheels smoothly pass over the door and do not interfere with the drive. Furthermore, even if rainwater or the like enters through the gap between the door and the concrete, it will be collected in the groove and will not enter the doorway. Furthermore, since concrete is placed on the ceiling and backfill soil, excluding the entrance and exit of the container, even if the container receives buoyancy from groundwater, it will not float up.
