Mountain stop (1) It aims to reduce the amount of excavation without removal, making it quick and cheap. The need for backfilling also contributes to ground protection. The mountain stopper (1) has an original role, a concrete formwork, and a frame that also serves as a waterproof layer base, and it is fast and cheap to make. The concrete of the skeleton (4) in the waterproof layer (3) has a good liquid sustainability and is durable and accurate to be cast accurately because it has no water diffusion and no permeated water. Since the heat of vaporization and vaporization in the waterproof layer (3) is well dissipated and there is no make-up water, the drying time is fast and the hardened concrete can be used easily and the strength can be increased. The coating film (3) of the skeleton (4) protects the cement components from seeping out by fusion with groundwater and weathering with wind and rain, and prevents oxidation of the reinforcing bars to extend the service life of the skeleton. The flexible waterproof layer prevents the occurrence of cracks in the body (4), and at the same time repairs can be resolved by water-stopping technology, extending the useful life. If it is also used as a foundation, it matches the increasing number of basements in urban areas where a great earthquake is expected, and it is effective as a shelter because it extends the useful life of the upper building.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION
Originally a temporary material used as a mountain retaining wall, it is an outer formwork that also serves as a waterproofing base and reinforced concrete, and does not require extra excavation and backfilling.

When the construction site is in the spring ground condition, a drainage kettle is installed outside the skeleton and treated by drainage machinery to stop the waterproof layer construction surface, and a waterproof sheet is applied to the concrete of the mountain stop frame and the bottom plate. Stick

The method of the present invention can be applied to the construction site of a small section of a road with a narrow road of at least 4 m according to the Building Standards Act by carrying in a small machine.

The outer waterproofing method is an erosion preventing construction method for protecting and protecting concrete cement components from being eroded by acid rain and groundwater over all underground structures.

[0005] Over the entire underground structure, the outer waterproofing method is an electrolytic corrosion preventing method that cuts off the underground current of metals and suppresses the occurrence of electrical corrosion.

[0006] The waterproof sheet relates to a manufacturing method in which, when concrete cracks occur, the waterproof sheet is wrapped in a seamless manner to maintain the waterproof ability and to prevent water leakage and dew condensation, and to prevent water leakage on the outside both in the field and in factory production. It is a thing.

[0007]

2. Description of the Related Art Conventionally, it has been common knowledge by experts that leakage and dew condensation in the basement is natural, and most of the people who explain it do not have any doubt. When spring water was selected, a drainage area was attached and a large number of environmental equipment such as dehumidifiers were used, and the usage range was often non-resident.

[0008] These drainage and dehumidifier installations are viewed as cultural and status rather than natural and are economically costly.

With the indoor waterproofing method by applying or spraying or painting after the basement building is completed, it is impossible to completely cope with the breathability of concrete and the infiltration and condensation of fine cracks, and maintenance is required each time. ing.

The indoor waterproofing method is such that the waterproof inner layer cannot withstand pressure due to a long-term hydrostatic long-term load, causing damage and peeling, resulting in an unpleasant living environment due to water leakage and dew condensation, and a large amount of post-measure measures are required. It costs money.

Excessive excavation of the construction site to stop the mountain and removal of the mountain stop requires common knowledge that a large amount of excavated earth and sand must be treated and backfilled, and foreign material contamination during backfilling work must be completely avoided. It is impossible, and it is impossible to confirm the existence of the foreign matter.

Too much dissatisfied with the large amount of money invested is due to the imperfect waterproofing of the inner surface of the post-treatment, and the manufacture of a full-scale basement at a mass price that emphasizes a healthy and comfortable housing environment. No method has been developed.

[0013]

[Problems to be Solved by the Invention] It is natural that the basement is to admit water leakage, and it is natural that it is humid and moldy and lacks health consideration as a living environment. The treatment costs of equipment require facility capital and operation and maintenance costs, which also have a permanent fixed economic burden.

[0014] Due to lack of efforts of specialists and accompanying mechanical equipment,
The basement has a high-priced preconception, an economically popular price, and it is not possible to manufacture it in earnest.

The mountain stopper dismantling and removal method requires a work space place and is not suitable for setting up a small land, and excavates extra to increase the disposal amount of earth and sand, as well as road conditions due to carrying in and out and disposal sites. Have an impact. It takes time to stabilize the ground for the backfill soil, which is a cause of high cost.

The installation of environmental equipment to improve the living environment by eliminating moisture is due to the method of stopping the dew condensation appearing on the concrete surface inside the room. Fine cracks in concrete cause immediate leakage of water and leave anxiety, and the invention is incomplete, and the present invention was devised to solve these drawbacks.

[0017]

The basis for solving the drawbacks of the conventional basement is characterized by an outside waterproofing method utilizing a cleat.
While driving the main pillars (1 to a) into the work site (6) and excavating, the sheet piles (1 to b) are attached between the pillars without any gaps, and FIG.
It is a base layer for waterproof layer of the wall, which is basically used as well as a frame (1) for combined use with concrete. When the ground is good and there is no need for cliffs, use a simple wooden frame and plywood frame Figure 3. These formwork will be buried.

To generate spring water, a drainage canal and a pumping kiln will be installed outside, which will be the body, and the bottom will be split stone and gravel, and if necessary, ground reinforcement will be used to stabilize the ground and eliminate water. .

When water stoppage is required, water stoppage treatment is performed with a ground strengthening agent and a resin curing agent. Solidify with abandoned concrete (2) at the bottom of the excavation base pile (6), and use it as a waterproof layer base for the floor, and then use black ink.

A waterproof sheet (3
~ A) are attached to each other with an adhesive to form a seamless waterproof layer that is integrated with the floor and wall to form a structural container waterproof container. The wall sheet should be stretched in preparation for joining the ceiling part.

If the mold is moist and cannot be directly bonded,
Take extra sheet stacking margins and fix it to the sheet pile with a tucker or pressing plate and nail screws, and seamlessly adhere the sheets to each other with a rubber double-sided adhesive tape. If necessary, an adhesive such as an epoxy resin is added to the adhesive tape and used together.

On the waterproof sheet (3 to a), a resin foam material (3 to b) which also serves as a protector, heat insulation, and double waterproofing is uniformly blown and adhered.

The reinforcing bars (4 to a) of the structural frame (4) are integrated with the floor and the lower end of the wall and the underground beam provided when necessary, and concrete (4 to b) is struck on the floor portion to a required thickness. Harden the bottom plate.

Next, the rebars (4 to
B) are integrated and integrated. Then, the inner concrete formwork (5) of the wall and the ceiling forming the main body is installed. Then, concrete (4 to B) is integrally driven in order from the wall to the ceiling, and the building of the body is completed.

The remaining outer waterproof ceiling portion and a part of the wall are formed by foaming layer (3 to b) and sheet layer (3) after solidification of the skeleton concrete.
~ Add a) to complete.

In the case of a more solid underground evacuation shelter, etc., a waterproof layer (3) added to the formwork (1) waterproof layer (3) structure (4) shown in FIG. 1 and FIG. The construction of the body (4) is repeated and repeated to enhance quality and durability. When multiple layers are used, the foaming agent (3 ~
The method of omitting step b) is also applied.

In the above grades, the H-shaped steel is
Wood, iron pipes, rails, and waterproof layer bases are made of wood, plywood, trench sheets, sheet piles, and iron plates on the basis of sheet piles. The main material of the waterproof layer is rubber sheet, resin sheet, and adhesive is rubber tape, resin sheet. The solvent and blowing foaming agent are selected from resin type and rubber type. However, in order to achieve the purpose without making any difference, the materials are not restricted from being used and selected from all the materials that are considered appropriate. An outer waterproof basement with the above structure by filling in the formwork.

[0028]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is to provide a comfortable indoor environment by externally waterproofing (3) a basement skeleton body (4) to eliminate moisture and suppress generation of mold.

By waterproofing the outside (3), dehumidifying equipment and drainage equipment are omitted, and the work is reduced.

[0030] Mountain stop (1) The amount of excavation is reduced by the burying method without removal, and the work is speeded up and the cost is reduced. In addition to the need for backfilling, it contributes to ground protection. A perfect waterproof basement can be easily made by using the mountain stopper (1) as the original function, the concrete formwork, and the dual-purpose frame of the waterproof layer base.

Since the concrete poured into the skeleton (4) inside the waterproof layer (3) is inside the completely waterproof layer (3), there is no escaping of moisture to the outside and no permeated water from the outside, so that it is in a liquid state. It is possible to drive it accurately in every corner. Further, the heat of vaporization of solidification in the waterproof layer (3) is well dissipated, the supplied permeated water from the outside is sealed, the solidification time is short, the use of hard concrete is facilitated, and it contributes to the improvement of the core strength.

The skeleton (4) coating waterproof layer (3) is an important protector to prevent erosion due to external permeating liquid such as groundwater and acid rain, to prevent erosion of neutralization of cement components and oxidation of rebar, and to prevent erosion. Contributes to improving the durability of the body.

Further, it blocks the underground current and exerts an electrolytic corrosion preventing effect of protecting from electric corrosion, and contributes to the extension of the service life of the skeleton.

When the skeleton (4) is cracked, the effect of the waterproof double-layer waterproof layer can be maintained for a long time because of the characteristic of the waterproof double sheet.
