JPH08246486A - Underground wall outside waterproofing construction device - Google Patents

Abstract

PURPOSE: To eliminate a need for surplus excavation and refilling and to shorten a term of works by a method wherein during construction of a landslide protection wall, spring water from the excavation side is cutoff by non-woven cloth and a waterproof sheet with a mounting and demounting tape and water immersion from a bolt is cutoff by a moisture expansion rubber packing. CONSTITUTION: A bolt 2 with a seat is fused to a landslide protection steel pile and a rubber ring 3 and a moisture expansion rubber packing 4 are mounted to the bolt 2 with a seat. Further, non-woven cloth 5 and a waterproof sheet 6 are applied in such a manner to cover and the bolt 2 with a seat is extended through. The moisture expansion packing 4 is attached again and a round separator 8 is attached by a hexagonal bolt 7. Further, wood concrete 9 and forms 10 are attached and concrete is placed. This constitution effects waterproofing at the outside of an underground wall and cuts off spring water. Further, a need for surplus excavation and refilling is eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to an outer waterproofing device for an underground wall.

[0002]

[Prior art]

(B) When waterproofing the outside of the basement wall, when performing mountain retention,
A steel pile is struck about 500 mm outside the wall to be newly made, earth is stopped and excavated, a formwork is built, a round wall separator with a wall thickness is attached, a formwork is also attached, concrete is placed, and a new building is constructed. After making and removing the formwork, the outer wall was waterproofed, and the space was backfilled and leveled. (B) If you do not waterproof outside the basement wall, put 1 inside the wall.
Create a space of 00 mm, make a double wall by brick or panel stacking, and use the spring water from the outer wall
It was poured into a 0 mm space and put in a water storage pit, and when the volume increased, forced drainage was performed.

[0003]

The conventional method has the following drawbacks. (B) Width of about 500 people can put in if it is waterproof on the outside of the basement wall
mm must be excavated extra and then backfilled. (B) In the method of making a double wall inside, the inner wall was made of bricks or panels. The work was done after removing the formwork of the underground wall, and the construction period for the interior work was delayed. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problem] A bolt (2) with a seat is welded to a steel pile (1) for retaining a mountain, a ring (3) and a water-expandable rubber packing (4) are fitted, and a non-woven fabric (5) is attached thereon. Hang it so that it covers the waterproof sheet (6) with desorption tape, penetrate the bolt (2) with a seat, attach the water-expanded rubber packing (4) again, and tighten it with the hexagon bolt (7), (8) is attached to the wooden container (9) and the form (10), and concrete is poured. With the above device, it is possible to waterproof the outside of the underground wall and disconnect the spring water.

[0005]

[Operation] The spring water from the excavation side was blocked with a non-woven fabric and a waterproof sheet with a desorption tape, and water from the bolts could be blocked with a hydrous expansion rubber packing. The joint of the waterproof sheet with desorption tape should be a sheet with a fitting fastener and be joined with a joint roller. With this, there is no inundation. Regarding the water-containing expansive rubber packing, it was used that the rubber expands when it contains water and the outside expands only by fixing it with hard rubber.

[0006]

EXAMPLES Examples of the present invention will be described below. (A) About 600 m of the bolts (2) with seats on the Yamadome steel pile (1)
Weld at m-square intervals. (B) Fit the rubber ring (3) on the seat bolt (2). (C) After fitting the rubber ring (3), fit the water-containing expanded rubber packing (4). (D) After fitting the water-expanded rubber packing (4), spread the non-woven fabric (5) and cover it. (E) The non-woven fabric (5) is covered, and the waterproof sheet (6) with a detachable tape is covered, and the non-woven fabric (5) and the waterproof sheet (6) with a detachable tape are penetrated through the seat bolt (2). (F) After penetration, reattach the water-containing expansive rubber packing (4). (G) After fitting the hydrous expansion rubber packing (4), tighten it with the hexagon bolt (7). (H) After tightening the hexagon bolts (7), attach round separators (8) for concrete thickness. (I) Put a wooden container (9) on one side of the round separator (8). (N) After the wooden concrete (9), form is assembled and concrete is poured. As a precaution, when pouring concrete, place the non-woven fabric (5) and waterproof sheet (6) with desorption tape on the mountain retaining side.
Be careful not to let concrete enter, and when placing concrete on the ground, place concrete between the non-woven fabric (5) and waterproof sheet with desorption tape (6) and new wall so that concrete will never enter. Things are important. It may cause flooding.

[0007]

【The invention's effect】

(B) The fact that the use of the present invention eliminates the need for extra excavation and backfilling of the existing construction method has made the treatment of industrial waste a big social problem recently, and the amount of extra excavated residual soil can be reduced. Things are big. (B) Making a double wall on the inside is a cause of delaying the construction period of the interior, and it can be solved that the internal volume also becomes small.

Claims (1)

[Claims] 1. A seat bolt is welded to a mountain retaining steel pile, a ring and a water-containing expansion rubber packing are attached to the seat bolt, and the non-woven fabric and a waterproof sheet with a detachable tape are hung so as to penetrate the seat bolt. Attach the water-expanded rubber packing again to
A waterproof construction method outside the underground wall where hexagonal bolts were used to attach round separers, wooden concrete and formwork were attached, and concrete was placed.
