Abstract

PURPOSE:To facilitate construction work, and to shorten construction period by executing the piping work of an indoor drainage piping simultaneously with the foundation work which is to be previously carried out before temporary scaffolding. CONSTITUTION:Steel reinforcements of an underground beam part 6 in an excavation region is assembled, and at the same time an underground beam penetrating sleeve 4 is incorporated. A form for the underground beam part is assembled with both an outside-wall form 7 and an inside-wall form 8 so as to surround the steel reinforcements, and concrete is placed in this form, and after it has been hardened, the outside-wall form 7 is removed, and then an outdoor drainage sump 3 is installed. Then, the sump is connected with the underground beam penetrating sleeve 4 by means of a fitting pipe 1. Thereafter, the surroundings of the building are backfilled for commencing construction work, and with the progress of work the inside-wall form 8 is removed, and an indoor drainage piping is extendedly connected to a socket 2. Thus, at the time of foundation work, external drainage piping work can be simultaneously carried out, so that construction period can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for constructing an outdoor drain pipe that connects a building and a drainage basin installed on the premises of the building.

(Prior art) Conventionally, in the construction of a building, an underground beam that will serve as the foundation of the building is built on the excavated ground surface, and then immediately backfilled, and then temporary scaffolding is erected around the building to construct a shed. It is carried out. In addition, piping work for outdoor drain pipes connecting the building to the drainage basin installed on the premises of the building is carried out at the time when the exterior work of the shed is completed and the temporary scaffolding is removed. In other words, construction of the drainage pipe could not be carried out until the scaffolding was dismantled. (Problem to be Solved by the Invention) However, in the conventional construction method described above, the time for dismantling the scaffolding is often just before the completion of the construction, and therefore the construction of the outdoor drainage pipe has to be completed in a short period of time. .

Moreover, the construction of the drainage pipes during this period also involved external construction work such as paving and planting, so it took a lot of effort to coordinate the work.

In addition, especially in cold regions, many buildings are completed before the winter season, making the work even more hectic and hectic, and moreover, it is sometimes interrupted due to weather conditions such as snow or ice.

The present invention was made in view of the above circumstances, and it is possible to simplify the construction work and shorten the construction period by constructing the outdoor drainage pipe in conjunction with the foundation work that is performed prior to the assembly of the temporary scaffolding. The purpose is to provide a construction method for outdoor drainage pipes.

(Means for Solving the Problems) That is, the above-mentioned object of the present invention is to provide a method for constructing an outdoor drain pipe that connects a building and a drainage basin installed outside the building via a mounting pipe, in which the ground surface is excavated. After constructing the underground beams that will become the foundation of the building in the excavated area and before backfilling the excavated area, piping work for the attachment pipe is carried out, and then, prior to assembling the scaffolding for constructing the building shed. This is achieved by a method for constructing an outdoor drain pipe, characterized in that the underground beam portion and the attachment pipe are buried under the ground.

(Function) Since the external drainage pipe work is performed at the same time as the foundation work, the re-excavation work and re-filling work after dismantling the scaffolding, which were performed in the conventional process, are omitted, making the work easier and shortening the construction period. Shortening can be achieved.

In addition, since the piping work is carried out at a relatively slow time when construction starts, there is ample time for the work to be completed.

Additionally, water flow tests can be performed immediately upon completion of connection to indoor piping.

(Example) Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is an overall structural diagram illustrating the method of constructing an outdoor drain pipe according to the present invention.

In the figure, ■ is a mounting pipe that connects an outdoor drainage basin 3 installed on the premises and an indoor drainage pipe (not shown), 2 is a socket for connecting the indoor drainage pipe to the mounting pipe 1, and 3 is a socket for connecting the indoor drainage pipe to the mounting pipe 1. 4 is an underground beam penetrating sleeve for piping, 5 is mortar for filling holes, 6 is an underground beam section, 7 is an outer formwork for constructing the underground beam section 6, and 8 is an inner mold. It shows the frame. In addition, the part indicated by the symbol CL represents the ground surface, and the part shown by line A represents the excavation area of the ground surface for construction work.

Scaffolding 11, which is to be assembled around the building on the outdoor drainage basin 3, is shown by a dashed line, and the outer wall 12 of the building, which is constructed on the first floor slab 9 continuous to the underground beam part 6, is shown by a broken line. There is. Next, a working procedure based on the method of the present invention will be explained. First, as foundation work for the building, reinforcing bars that will become the core material of the underground beam section 6 are assembled in the excavated area of the ground surface GL, and the underground beam penetrating sleeve 4 is assembled.

Next, a formwork for the underground beam is assembled using the outer formwork 7 and the inner formwork 8 so as to surround the reinforcing bars, and concrete is poured into the formwork to carry out pouring work. Once the concrete has solidified, the outer formwork 7 is removed and the outdoor drainage pipe piping work is carried out. That is, an outdoor drainage basin 3 is installed within the building site, and the drainage basin 3 and the underground beam penetrating sleeve 4 are connected by the attachment pipe 1. At the same time, the hollow and exposed parts of the sleeve 4 are filled with hole-filling mortar 5. Once these works are completed, the area around the building will be backfilled and the ground leveled, temporary scaffolding will be erected around the building, and construction work on the shed will begin. Meanwhile, as the construction of the shed progresses, the inner formwork 8 is removed and the indoor drainage pipe is connected to the socket 2 and extended. With the above steps, the drainage pipe piping work is completed.

(Effects of the Invention) As described above, according to the outdoor drainage pipe construction method of the present invention, the piping work is performed at the foundation construction stage.
Excavation and backfilling of the ground surface only need to be done once, making the construction easier and shortening the construction period. In addition, since the outdoor drainage pipe work is not carried out right before the completion of the construction, it is possible to avoid overlapping with other works such as paving, which not only eliminates complication, but also allows construction to be carried out at a relatively slow time when construction begins. Also,
Since drainage pipe work is completed at the early stage of construction, water flow tests can be conducted sooner than before.
