Abstract

PROBLEM TO BE SOLVED: To allow fixation to a drain pipe on a vertical/tilting wall and retrofit to a drain pipe buried in a structure by providing a soil outflow preventing mesh type filter part on the inside and providing a fixing part to be installed and fixed to a mold for the vertical/tilting wall. SOLUTION: When a drain pipe having a mesh type filter part 3 on the inside of a cylinder part 2 is installed to a mold while using a filter with a fixing material as a fixing material, the drain pipe is fixed to a mounting pipe insertion part 7 installed by means of a nail through the use of a nail hole projection part for a nail hole in the outer circumferential face of a cylindrical fixing part 1. In retrofit a drain pipe buried in a finished structure, a filter with a drain pipe fixing material, which allows complete fixation in spite of the difference of the inside diameter because of the function of a dimension regulating part 6 on the outer circumferential face of a cylindrical part 2, is used on the drain pipe inside. In this way, outflow of soil can be surely prevented and installation to a vertical/tilting wall can be carried out completely.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for fixing a drainage pipe of a concrete retaining wall to a formwork at a predetermined position and for completely preventing drainage of soil from the drainage pipe.

2. Description of the Related Art In general, a filter for a drain pipe of a retaining wall structure has a mesh sheet or a fibrous mat attached to an inlet of the pipe by a nail or a gum tape. In some cases, the object could not be achieved.
In addition, the drainage pipe was mainly fixed with nails.

SUMMARY OF THE INVENTION According to the present invention, a drainage pipe fixing material having a filter capable of completely fixing a drainage pipe to a vertical wall or a sloped wall and preventing sediment from flowing out from the drainage pipe is provided. It is an object of the present invention to provide a filter with a fixing material, which can be used later even for a drain pipe embedded in a structure.

According to the present invention, there is provided a filter with a fixing member for a drainage pipe, which has a net-like filter portion for fixing a drainage pipe on a concrete retaining wall and for preventing soil drainage of the drainage pipe. The drain pipe has two shapes so that it can be fixed to a vertical wall or a sloped wall form.

BEST MODE FOR CARRYING OUT THE INVENTION The filter with a fixing member for a drain pipe according to the present invention can be fixed by attaching the drain pipe to a predetermined position of a formwork on a slope wall and a vertical wall, and a net-like filter portion is used as a material for preventing sediment outflow. It is intended to perform the function of. The structure is such that a filter with a drainage pipe fixing material embedded in the finished structure can be attached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a side view showing a schematic structure of a filter with a fixing member for a drain pipe according to the present invention,
2 is a front view, 3 is a back view, 4 is a side sectional view, FIG.
FIG. 6 is a side view of the construction example. When a filter with a fixing member for a drainage pipe is attached to a formwork as a fixing member, a pipe insertion portion 7 is attached by a nail using a nail hole convex portion 4 for a nail hole 5 on the outer peripheral surface of the cylindrical fixing portion 1. Drain pipe 8
To fix. The filter is provided with a mesh filter portion 3 in the tubular portion 2 of the filter with the fixing member of the drainage pipe.
When the filter is attached later to the drainage pipe embedded in the structure 9 finished as a filter with a fixing material for the drainage pipe, the inside of the drainage pipe is operated by the dimension adjusting part 6 on the outer peripheral surface of the tubular part 2. This is a filter with a fixing material for drainage pipes, which has a structure that allows complete fixing even if the inside diameter is different for fixing.

As described above, according to the present invention, the following excellent effects can be obtained. That is, the filter with the fixing member of the drainage pipe, which is highly operable and secures the prevention of earth and sand outflow as a filter at the same time as being fixed to the formwork with respect to the drainage pipe and can be completely attached.

Claims (1)

[Claims] The filter with a drainage pipe fixing material according to the present invention has two types of shapes, one for vertical use and one for gradient use, and has a cylindrical fixing portion for fixing the outer peripheral surface of the drainage pipe and the inner periphery of the drainage pipe. When used as a fixing material with a filter, a nail hole convex part having a nail hole for mounting a formwork on the outer peripheral surface of the cylindrical fixing part is used. In the case of a filter which is attached later to a drain pipe attached to a structure, the filter has a dimension adjusting portion which can fix even if the inner diameter of the pipe is different. A filter with a fixing material for a drainage pipe with a structure consisting of a mesh filter inside the tubular part.
