Description

Basement waterproof structure

technical field

The utility model belongs to the field of building waterproofing, in particular to a basement waterproofing structure.

Background technique

With the continuous development of the construction industry and the acceleration of urbanization, the types and numbers of basements are increasing, and the requirements for basement waterproofing are getting higher and higher. If the basement waterproofing work is not done well, it will seriously affect the normal use of the basement, and the repair cost Also very expensive. The current traditional method of basement waterproofing is to lay waterproof membranes or paint waterproof coatings on the concrete base. Influenced by improper handling of joints and different levels of groundwater pressure, a single combination of rigid self-waterproofing and flexible waterproofing is difficult to meet the waterproofing requirements in places with high waterproofing requirements. It is not only difficult for completion acceptance, but also brings difficulties for repairs. Therefore, basement waterproofing should be based on the actual situation of the basement to achieve the principle of combining anti-drainage and adapting measures to local conditions. It must not only have a reasonable waterproof structure level, but also grasp the construction quality, so that the basement waterproof can reach the design service life.

Utility model content

The technical problem to be solved by the utility model is to provide a basement waterproof structure with low comprehensive cost, good waterproof performance and high cost performance, so as to meet the needs of the construction market for basement waterproof with ideal comprehensive performance.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions: basement waterproof structure, including planting roof, side wall and bottom plate, planting roof includes self-waterproof concrete roof of structure from inside to outside, polymer waterproof slurry, waterproof coiled material , storage and drainage board, non-woven fabric, planting soil and vegetation layer; the side wall includes structural self-waterproof concrete side wall from inside to outside, polymer waterproof slurry, waterproof membrane, storage and drainage board and backfill soil; the bottom plate includes The structure from outside to inside consists of waterproof concrete base plate, waterproof membrane, fine stone concrete cushion and backfill.

The waterproof membrane is TPO waterproof membrane or PCM reaction bonding polymer composite waterproof membrane.

Siphon drainage holes are reserved on the planting roof, the polymer waterproof slurry is polymer-modified flexible polymer cement-based mortar, the storage and drainage board is high-impact polystyrene plastic board, and the non-woven fabric is polypropylene non-woven fabric.

Aiming at the shortcomings of unreasonable levels and low waterproof level of some basement waterproof structures, the inventor designed a basement waterproof structure, which provides comprehensive protection from three aspects: the planting roof, side walls and bottom plate of the basement, wherein: the planting roof includes from inside to External structural self-waterproof concrete roof, polymer waterproof slurry, waterproof membrane, storage and drainage board, non-woven fabric, planting soil and vegetation layer; side walls include structural self-waterproof concrete side walls from inside to outside, polymer waterproof Slurry, waterproof membrane, storage and drainage board and backfill soil; the base plate includes a structural self-waterproof concrete base plate from the outside to the inside, waterproof membrane material, fine stone concrete cushion and backfill soil. Accordingly, the inventor has also established a corresponding construction method. Compared with the prior art, the utility model has the following outstanding advantages:

1) The structural self-waterproof concrete top plate is constructed by shot blasting or pouring and troweling, which ensures the strength of the base layer and places the waterproof layer on a solid structure; the polymer waterproof slurry used as a waterproof membrane binder has good It has excellent elasticity and low shrinkage, and is firmly bonded to the base concrete without falling off or cracking. At the same time, it also has excellent waterproof performance and can seal micro-cracks in the structure; the basement planting roof structure adopts storage and drainage boards and siphon drainage. It can not only retain an appropriate amount of water to meet the needs of vegetation, but also drain excess water through siphon action to ensure that the root system of vegetation is not corroded.

2) In the structure of the side wall of the basement, the storage and drainage board plays a soft protective role in the waterproof layer. The convex point of the storage and drainage board faces outwards, and the non-woven fabric is pasted to form water filtration and water permeability, which is in line with the "combination of drainage and defense" Waterproof principle; moreover, the soft protection of the storage and drainage board is a permanent waterproof protective layer. Compared with polystyrene boards, the cost is reasonable, more environmentally friendly and energy-saving, and it is also conducive to reducing dew condensation in the basement.

3) The waterproof membrane construction in the basement floor structure adopts the pre-paved anti-adhesive method, and the waterproof layer reacts with the hydration heat of the floor waterproof concrete to form a skin-type waterproof layer, which completely solves the risk of water leakage; at the same time, it can effectively avoid the traditional method (waterproof Layer bonded to the cushion) due to the collapse of the backfill, the cushion sinks and cracks, thereby tearing and destroying the waterproof layer, forming a true "frontal waterproof".

In a word, the waterproof structure of the basement of the utility model is composed of the basement planting top plate, side walls and bottom plate to form a "full outsourcing" skin-type waterproofing for the entire basement. It meets the needs of the construction market for basement waterproofing with ideal comprehensive performance, and is suitable for waterproofing of basements and other underground buildings.
