Description

Waterproof protection device and waterproof construction method using the same {Waterproof protection and waterproof construction method using the same}

The present invention relates to a waterproof protection device and a waterproof construction method using the same, and more particularly, it is installed on the top and outer surfaces of an underground structure such as an underground parking lot to prevent water from leaking into the underground structure and at the same time It relates to a waterproof protection device configured to enable construction and a waterproof construction method using the same.

In general, a waterproofing treatment is applied to an underground structure such as an underground outer wall of a building and an upper slab of an underground parking lot to prevent water from leaking into the underground structure from the outside.

In this case, waterproofing is usually performed first with a waterproofing layer using rubberized asphalt or a similar waterproofing material on the outer surface of the underground structure.

Meanwhile, after the waterproof layer is constructed, the waterproof layer protection work is performed to protect the waterproof material. To protect the waterproof layer, conventionally used waterproof layer protection methods include placing a 20 to 30 mm thick waterproof layer protection mortar on the top surface of an underground structure, or placing a 20 to 50 mm thick polyethylene foam board on the waterproof layer. Afterwards, it is finished by pouring the waterproof layer pressing concrete or backfilling the soil as a subsequent process.

In the case of the outer wall, 0.5B cement racking or 20~50mm thick polyethylene foam board is attached to the waterproof layer, and then finished with soil backfilling as a subsequent process.

As described above, the waterproof layer protective brick stacking and waterproof layer protection mortar placement method for protecting the outer wall waterproof layer of an underground structure is a waterproof layer protection method that has been used for a long time, and the protective brick stacking is a method of laying back the soil due to the stiffness of cement bricks. While there is little risk of damage to the waterproof layer due to low risk of damage to the waterproof layer, it has excellent protection role for the waterproof layer, but there are disadvantages in that the construction period is long due to the difficulty of stacking bricks in a narrow basement work space, excessive labor costs, and a long work period.

In particular, when pouring pressed concrete, a separate formwork must be placed on the upper part of the waterproofing layer so that the concrete does not flow arbitrarily, so that the number of work is increased.

In addition, the work of pouring a 20-30mm waterproof layer protection mortar to protect the waterproof layer on the top surface of the underground structure has an excellent protection role for the waterproof layer, but the construction labor cost is excessive and it is difficult to proceed with the subsequent process during the curing period of the cement mortar. There is a problem that the construction period is prolonged. In particular, there is a problem that a lot of sealing, manpower, and cost are required to be applied to a large underground structure such as an apartment complex.

In addition, since the corner part formed by the top surface and the outer surface of the underground structure is protected only by a thin waterproof layer of about 20 to 30 mm, water may leak through the crack when a crack occurs in the corner part. There is also a problem.

Accordingly, there is a need for a waterproof protection device and a waterproof construction method using the same, which is configured to prevent water from leaking into the underground structure and to enable relatively quick construction.
