Description
Technical field
The present invention relates to the structural concrete of a kind of large-scale dell, be specifically related to one and have for large deep foundation pit anti-
The structural concrete of water conservation.
Background technology
In building trade, especially large-and-medium size cities high-rise civil building and commercial building, the most all use supporting
Deep basal pit Large Underground Parking Space form, increases available space as far as possible and reduces cost, but at present, China's overwhelming majority underground
Engineering all uses traditional material, traditional construction construction technology waterproof layer, and the defect of this way is when waterproof layer is destroyed,
Subsoil water can form crossfire between waterproof layer and structural concrete, and current Chinese large-sized deep basal pit has supporting underground waterproof engineering
The ratio that pre-installed and inverted adhered new waterproofing techniques uses is the lowest, and it has bigger development and application prospect in China, promotes energetically
The development of this technology will produce huge economic benefit and social benefit.
Summary of the invention
The present invention provides a kind of structural concrete for large deep foundation pit with waterproofing protection, solves traditional structure and mixes
Solidifying soil, when carrying out waterproofing protection, often occurs that waterproof layer crushes, and subsoil water is crossfire between waterproof layer and structural concrete
Problem.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of structural concrete for large deep foundation pit with waterproofing protection of the present invention, including steel nail, special washer, base
Layer, waterproof roll, supporting construction, external corner, inner corner trim and structural concrete, the outside of described supporting construction is provided with described basic unit, institute
Stating that basic unit and described supporting construction are fixing to be connected, the outside of described basic unit is provided with described waterproof roll, sets in described waterproof roll
Having weathering layer and mucigel, the weathering layer of described waterproof roll is fixing with described basic unit to be connected, and described waterproof roll is provided with institute
Stating steel nail, be provided with described special washer between described steel nail and described waterproof roll, described steel nail is divided by described special washer
Not fixing with described basic unit and described supporting construction and be connected, the outside of described waterproof roll is provided with described structural concrete, described
Structural concrete is fixing with the mucigel of described waterproof roll to be connected.
As a preferred technical solution of the present invention, described basic unit is provided with described external corner and described inner corner trim, described sun
Angle and described inner corner trim are arc chord angle and arrange.
As a preferred technical solution of the present invention, the radius of described external corner is more than 20mm, and the radius of described inner corner trim is big
In 50mm.
As a preferred technical solution of the present invention, at the minor face overlapping the slot of described waterproof roll, it is provided with encapsulant,
The coiled material on described waterproof roll overlapping the slot both sides connects by encapsulant is fixing.
As a preferred technical solution of the present invention, the outside of described waterproof roll is provided with some circle reinforcing bars, and reinforcing bar
Fix with described waterproof roll and be connected.
The present invention is reached to provide the benefit that: by arranging waterproof roll, then arranges steel nail on waterproof roll and fix
Coiled material, forms firm continuous print bonding, it is achieved straight to structural concrete after structural concrete solidifies between coiled material with concrete
The waterproofing protection connect；The setting of the mucigel on waterproof roll, when preventing waterproof layer local failure, secondary water is at waterproof layer and knot
Channelling between structure concrete, and this technology is greatly lowered and may send out while raising waterproof layer is to structural defence reliability
Raw leak maintenance difficulty and expense, it is not necessary to laying any protective layer can directly carry out assembling reinforcement, installs template, pours knot
The operations such as structure concrete, it is achieved that less operation, reduce the duration.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, with the reality of the present invention
Execute example together for explaining the present invention, be not intended that limitation of the present invention.
In the accompanying drawings:
Fig. 1 is the overall structure signal of a kind of structural concrete for large deep foundation pit with waterproofing protection of the present invention

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein
Execute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment: as it is shown in figure 1, a kind of structural concrete for large deep foundation pit with waterproofing protection of the present invention, bag
Include steel nail 1, special washer 2, basic unit 3, waterproof roll 4, supporting construction 5, external corner 6, inner corner trim 7 and structural concrete 8, supporting construction
The outside of 5 is provided with basic unit 3, and basic unit 3 is fixing with supporting construction 5 to be connected, and the outside of basic unit 3 is provided with waterproof roll 4, waterproof roll 4
In be provided with weathering layer and mucigel, the weathering layer of waterproof roll 4 is fixing with basic unit 3 to be connected, and waterproof roll 4 is provided with steel nail 1, steel
Being provided with special washer 2 between nail 1 and waterproof roll 4, steel nail 1 is fixed with basic unit 3 and supporting construction 5 respectively by special washer 2
Connecting, the outside of waterproof roll 4 is provided with structural concrete 8, and structural concrete 8 is fixing with the mucigel of waterproof roll 4 to be connected.
Basic unit 3 is provided with external corner 6 and inner corner trim 7, external corner 6 and inner corner trim 7 and is arc chord angle setting, and external corner 6 and inner corner trim 7 are circular arc
Angle is arranged, and prevents wedge angle from destroying waterproof roll 4.
The radius of external corner 6 is more than 20mm, and the radius of inner corner trim 7 is more than 50mm, and external corner 6 is too small with inner corner trim 7, to waterproof roll 4
Impact less.
Being provided with encapsulant at the minor face overlapping the slot of waterproof roll 4, the coiled material on waterproof roll 4 overlapping the slot both sides is by sealing
Material is fixing to be connected, it is simple to being end-to-end waterproof roll 4 minor face closely, prevents subsoil water from destroying supporting in entering waterproof layer
Structure 5.
