The utility model discloses furthest has guaranteed the flexible waterproof effect, guarantee effectively that the basement receives the side limit effect of the soil body, avoids worker's after strain of the peripheral soil body to sink with uneven, cheat the groove simultaneously and can obtain in time sealing, be convenient for site security construction and civilization management.
Description
Technical field
This utility model is related to a kind of single side formwork outer wall of basement with flexible waterproof layer external mold, belongs to civil engineering skill
Art field.
Background technology
Underground engineering rigidity pattern foundation pit supporting structure soil-baffling structure generally adopts diaphram wall, armored concrete or SMW engineering method row
The forms such as stake, and general make between campshed formula supporting construction and outer wall of basement is：There is 1 meter between campshed and exterior wall
The gap of left and right width, this gap is used as formwork erection outside exterior wall, pastes the working place of outside flexible waterproof layer, around foundation ditch one week
It is all provided with.The form of construction work of this exterior wall bilateral formwork is typically used in tradition along in practice underground engineering.
For being provided with the tradition of internal stay along practice foundation pit supporting project, inner support and to enclose purlin be interim；Basement main body
Structure along when making, from bottom to top must be removed temporary support, and change using basement flooring as permanent internal stay, concrete operation is such as upwards
Under（So that 2 layers of basement 2 road support as a example）：1 base plate → B2 supports and encloses purlin dismounting → B2 exterior wall → B2 external wall waterproof layer → B2
Gap backfill → B1 flooring and support replacement band reach 80% intensity → B1 and support and enclose purlin dismounting → B1 exterior wall → B1 external wall waterproof layer
→ B1 gap backfill → B0 flooring.Exterior wall bilateral formwork, successively construct, successively ram and fill out backfill.
But in most Practical Projects, because of various technology and administrative reason, exterior wall bilateral formwork is simultaneously successively poured into top
Sticking flexible waterproof layer more afterwards, and backfill in the narrow space that support replacement block is divided into.This traditional exterior wall is tied with supporting
Structure separate type（Wall shield separates）Construction, need about 1 meter wide, basement buried depth depth, by support replacement block be divided into dark, narrow and small
Complete waterproof layer and backfill construction in space, be primarily present following disadvantage：
（1）It is difficult to ensure that wall face sufficiently dry to meet the requirement pasting waterproof layer；
（2）Waterproof layer is stopped it is impossible to coat the whole face of exterior wall by the unnet purlin that encloses of support replacement block, dismounting；
（3）Backfill mostly using near coal-mine topple over by the way of, or even backfill building waste, cause the waterproof layer constructed to meet with
To destroying, flexible waterproof layer is made to lose efficacy；
（4）Near coal-mine topple over to dissipate fill out construction, and be support replacement block everywhere, remove unnet enclose purlin stop segmentation it is impossible to execution " point
Layer backfill and tamp, compacting factor be not less than 0.94 " code requirement；
（5）Backfill operation is thinked little of, engineering time assurance is loose, exposes to the sun and rain for a long time outside exterior wall, is easily formed
Permanent crack, damages exterior wall self waterproofing function；
（6）Exterior wall can not be backfilled in time with crater wall gap, and near coal-mine have potential safety hazard, is unfavorable for civilized construction and field pipes
Reason.
Utility model content
Stay wide pit for traditional basement foundation ditch to carry out exterior wall bilateral formwork, rear patch waterproof roll and backfill construction
Disadvantage on method and structure, coordinates basement agent structure-pattern foundation pit supporting structure integrated technique, and this utility model provides one kind
Single side formwork outer wall of basement with flexible waterproof layer external mold.
The technical scheme that this utility model is taken is as follows：
A kind of single side formwork outer wall of basement with flexible waterproof layer external mold, including outer wall of basement, described underground is outdoor
The bottom of wall is provided with waterproof base plate, is respectively provided on two sides with integrated internal stay side bar and Rigid Bracing Pile, described Rigid Bracing Pile and
Leave gap between outer wall of basement, be filled with the filling wall being made up of filling block in gap, in filling wall and basement
It is provided with one layer of flexible waterproof layer between exterior wall.
Anti-package is pasted on outer wall of basement bottom to described waterproof base plate upwards.
Described flexible waterproof layer is made up of waterproof roll, and two sides of described waterproof roll group are provided with glued membrane, and respectively
Mutually bonding with filling wall and outer wall of basement.
If described filling wall is divided into dried layer by enclosing purlin.
Described gap is 600mm.
The beneficial effects of the utility model are：
（1）Exterior wall is accomplished without any letup with flexible water, no other factors impact, ensures flexible water effect to greatest extent；
（2）Loose backfilling material in Practical Project or building waste are replaced with the casing that recycling material is made,
Lateral spacing effect that basement be subject to the soil body is effectively ensured, and no loosened soil outside wall, it is to avoid the post-construction deformation of the periphery soil body and uneven depression；
（3）While exterior wall pours, pit has been filled with, it is to avoid long-term expose it is ensured that greatly reducing while maintenance effect
The adverse effect expanded with heat and contract with cold, exterior wall concrete self waterproofing effect obtains effective guarantee；
（4）In integrated support system, pit width is not required to be limited by waterproof roll and backfill operation side,
600 is wide, reduces pit earth volume；
（5）Enclose purlin need not remove, transmit permanent component, the block of Water And Earth Pressures directly as supporting construction to agent structure
Body fills separation and the stiffening element of wall；
（6）Pit can be closed in time, is easy to site safety construction and civilization management.
Brief description
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the working procedure figure of this proof mechanism of water.
In figure：1- outer wall of basement, 2- waterproof base plate, 3- integration internal stay side bar, 4- main body beam slab, 5- rigid protection
