Description
Technical field
The present invention relates to technical field of building construction more particularly to a kind of underground waterproof engineering pre-installed and inverted adhered construction methods.
Background technique
Currently, China overwhelming majority underground waterproofing work is all made of conventional waterproof material as waterproof layer, waterproof material paving
It is affixed on bed course basal plane, then does protective layer, then casting concrete structure, waterproof layer is not bonded with structural concrete.This way
Defect when being that waterproof layer is destroyed, channelling can occur between waterproof layer and structure sheaf for underground water.Due to structure coagulation
Soil is porosity Inhomogeneous wave fields, is existed such as: because the vibrate honeycomb hole of not firm generation, objective factor cause in casting process
Concrete reserving gaps (construction joint, deformation joint etc.) and uneven settlement of foundation caused by structural cracks the defects of, channelling
Moisture between waterproof layer and structure sheaf will enter inside configuration along the defects of gap, hole of structural concrete, make
At leakage.
A kind of pre-installed and inverted adhered technology is described in " 10 new technologies of construction industry (2017 editions) ", using be covered with macromolecule from
Adhesive surface sky is layered on blinding layer by the waterproof roll of viscose glue film layer, and bonding is combined into cast-in-place concrete face upwardly
One, centre is without channeling water hidden danger；Even if waterproof roll is locally destroyed, water can be also limited to very a small range.Used in it
Waterproof roll not only reached international most advanced level in product technology compared with conventional waterproof coiled material, but also price also compares
Conventional waterproof coiled material is cheap.Waterproof effect is even more to lead over the latter, substantially increases reliability, the durability of buildings waterproof.
Summary of the invention
The present invention provides a kind of underground waterproof engineering pre-installed and inverted adhered construction methods, without setting screed-coat, to basic level requirement
It is low, not by weather and base's moisture effect；Waterproof roll top directly carries out reinforced concrete construction, greatly without doing protective layer
Construction speed is improved greatly；Work progress is cold-working industry, the flames of anger, non-toxic and tasteless, non-environmental-pollution and hidden fire-fighting danger, safety collar
It protects.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of underground waterproof engineering pre-installed and inverted adhered construction method, includes the following steps:
1) base cleaning；Flattening foot layer removes surface irregularities and greasy dirt；
2) unwrapping wire positions；Reference line when base upper surface releases waterproof roll paving, when guaranteeing waterproof roll paving
It is not in dislocation, crooked phenomenon；
3) node processing；It is arranged at the node including plane and facade junction, deformation joint, construction joint, pipe root
The additional enhancement layer of waterproof roll, additional enhancement layer are cut according to actual measurement size at the scene, and additional enhancement layer is using two-sided
Adhesive waterproof coil；Unstressed concentration position base and additional enhancement layer are glued using full, and stress concentration portion position is using empty paving；It is full viscous
Position before laying first brush oiliness base treatment agent, re-lay additional enhancement layer after dry；
4) waterproof roll is laid with；Waterproof roll selects reaction bonded type macromolecule wet-laying waterproof roll, using pre-installed and inverted adhered
The directly empty paving of method, after reserving overlap joint size according to the width of selected waterproof roll, carries out waterproof roll laying by reference line；It is laid with
When, the overlapping the slot of adjacent 2 width waterproof roll is staggered, and the length that is staggered is not less than 1500mm；Overlapping the slot is close using overlap joint Self-adhesive
It is real；Waterproof roll when being laid with downward, up, first drawn at the edge of surface isolation film by lap width cross-laminated film surface by bonding
It opens, then the isolation film of adjacent 2 width waterproof roll overlap edge is torn, overlap edge uses cold bonding knot；
5) waterproof roll receives waterproof sealing at head node；Waterproof roll after being laid with to brick fetal membrane upper pressing it is fixed, after pour
Band position waterproof roll reserves enough laps of splice, and upper cover plank sheathing is protected；
6) it finished product protection and inspects for acceptance；Waterproof roll carries out finished product protection after the completion of being laid with, and prevents sharp objects from hitting
Waterproof layer is stabbed, then weld waterproof roll surface sets interim safeguard measure if you need to weld job；Coiled material is prevented to be laid on inspection
After qualification, the isolation film on waterproof roll surface is torn before binding baseplate reinforcing bar, and spread plain water waterproof roll surface is thin
Mud powder；
The positioning of placing of reinforcement unwrapping wire, which uses, when reinforced concrete construction, under bottom plate spreads lime or logical line is drawn to carry out as control line
Construction, after the completion of lower placing of reinforcement construction, brush paint or the logical line of drawing are as control line on reinforcing bar；Reinforcing bar, which is hung, a little sets interim protection
Measure；When assembling reinforcement, concrete pad is first arranged, concrete pad bottom adds one layer of waterproof roll enhancing；Weld Bottom Board Steel
When muscle, interim protection baffle is set in welding operating surface.
Compared with prior art, the beneficial effects of the present invention are:
1) it is constructed using pre-laid method, waterproof roll forms waterproof layer new together in conjunction with basic plate face, the waterproof
Layer effectively prevents underground water channelling into it, even if waterproof roll part by water being limited to a small range destruction, side
Just it is quickly found out breakthrough and adopts an effective measure and carry out leak stopping, the hidden danger leaked again will not be generated；
2) waterproof roll combines together with major structure of construction, and waterproof performance is not influenced by main body structure sediment, can be effective
Groundwater infiltration is prevented, waterproof quality is substantially increased；
3) protective layer on waterproof roll can not be done, directly progress armored concrete pouring construction, while to basic level requirement
It is low, not by weather and base's moisture effect, speed of application is substantially increased, the construction period is shortened；
4) cold-working industry, the flames of anger, non-toxic and tasteless, non-environmental-pollution and hidden fire-fighting danger, safety and environmental protection are used；
5) waterproof layer have stronger chemical corrosion resistance, have good repellence to the buck from concrete, not by
House refuse and biological infestation, it is mould proof, it is corrosion-resistant.
