2. Description of the Related Art Normally, power is supplied to consumers by electric wires and a flexible conduit for protecting the electric wires, and a power meter, a switch, and the like are provided in the middle of the wiring. In addition, when a gas pipe, a communication line of a telephone, a cable of a CATV, or the like is drawn to a consumer, devices such as a gas meter and a protector are installed on the way. These devices and the like serve as a demarcation point for construction (also referred to as a property demarcation point or a management responsibility demarcation point) in supplying power or the like from a supply source to a consumer. For example, a contractor performs piping and the like from a supply source to equipment as primary work, and another contractor performs piping and the like from installation of equipment to a consumer as secondary work. Power, gas, communications, CA
Since the supply of TVs and the like is also performed by different companies, a plurality of different companies perform their own tasks with different construction periods. In such a case, the starting location of the piping and the like is arbitrarily determined, and the installation location of the equipment cannot be unified.

[0003] A piping draw-in box (hereinafter referred to as a draw-in box) accommodates these devices collectively.
The piping or wiring corresponding to each is drawn in. Conventional drop-in boxes include, for example, those shown in FIG. This is a self-supporting vertically long box having a space for accommodating a power meter, a gas meter, a switch, a protector, and the like, and is erected on the ground.

[0004] The lower part of the draw-in box is buried in the ground to form a draw-in part 30, from which one side surface is opened, and a plurality of pipes or wirings are drawn in therefrom. The ground portion of the drop-in box is a storage section 31 for storing various devices, and is divided into a plurality of spaces by a partition wall 32.
The housing positions of the various devices are determined in advance. For example, the uppermost row is a power meter mounting space, the lower level is a switch and protector mounting space, and the lower level is a gas meter mounting space. The accommodation section 31 has a door 33 on one side that can be opened and closed for each step, and the door 33 is provided with a meter window 34 from which a meter number can be read. Also,
The plurality of pipes and the like drawn from the drawing section 30 except for the gas pipe are collectively inserted into one protection pipe 35 and then reach each device.

[0005]

However, in the above-described apparatus, a pipe or the like is drawn in from one side of the opening of the drawing portion. Therefore, when the pipe or the like is drawn in from another direction, an insertion hole is provided in the side. Or it is necessary to bend pipes or the like so that they can be drawn from the open surface. The operation of providing such an insertion hole is not easy. In addition, it is stated in the Electrical Equipment Technical Standards and the Wired Telecommunications Law that the degree of bending of the pipe should be smaller in order to prevent damage to the electric wire at the time of passing the wire. Is not preferred.

Further, in the above-described apparatus, since a plurality of pipes and wires are collectively inserted into one protection tube, the diameter of each pipe or wire must be adjusted. Therefore, it is desirable that different contractors work at the same time, or that a single contractor collectively works on different pipes and the like, but it is practically impossible.

[0007] Further, the above-mentioned one has the inconvenience that the gas pipe must be fixed using a pipe wrench or the like in a narrow space in the draw-in box at the time of piping work of the gas pipe.

In addition, since the above-mentioned construction is self-supporting by backfilling with soil or the like, there is a possibility that a displacement of piping or the like may occur at the time of installation of equipment.
Susceptible to condensation due to moisture in the ground.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to eliminate inconvenience in a series of construction of pipes and equipment, and to fix pipes in an orderly manner corresponding to each equipment. It is an object of the present invention to provide a pipe pull-in box capable of performing the following.
