Description
Technical field
The present invention relates to cement concrete engineering field, particularly relate to a kind of Identification Beneath Concrete Slabs sealing property
Test device.
Background technology
Cement concrete paving, because of the advantage of self, is a kind of widely used form of mating formation.General, cement concrete
Paving all uses cast-in-place mode to complete making.This paving method, because of cheap, easy construction, occupies leading ground always
Position.Cement concrete pours needs 28 day curing period could form intensity completely afterwards.Temperature during maintenance, humidity are to coagulation
The intensity of soil, durability have considerable influence.On-the-spot maintenance is owing to more disperseing, it is difficult to use advanced maintenance measure.Along with
The lifting of transport need, these shortcomings that in-situ cement concrete cannot overcome display day by day.
Assembled cement concrete paving technology is a kind of environmental protection, quick novel construction technology of constructing.Prefabricated
Factory completes pouring and maintenance of cement concrete slab, then gets final product open to traffic after in-site installation.Concentration pre-casting can make
With advanced maintenance process, it is ensured that cement concrete quality, improve intensity and the durability of concrete.Dispersion installation has entirely
The feature of weather, overcomes the impact of adverse environment, can be in weather constructions such as cold, light rain, strong wind.Prefabricated in factory ensure that
In concrete, each built-in fitting, sensor, pipeline etc. are intelligent and the survival rate of functionalization equipment and positional precision.
Assembled cement concrete slab needs adjustment plate height journey to the faulting of slab ends eliminating between plate body in installation process.Plate
Space is there is after height journey adjusts and between lower floor.Fill up typically by injected hole reserved in plate body injects serosity
Space at the bottom of plate.Plate rising pouring slurry slurry material specifically include that the preferable material of mobility such as cement grout, CA sand.Serosity
In flow regime in injection process, inject and can solidify rear within a short period of time, thus provide uniformly to prefabricated cement board
And stable support.Can plate prime cement liquid fill, and the long-term behaviour of assembled cement concrete paving is had large effect.
Fluent material can to the low local flowing of potential energy, but in fabricated construction, at the bottom of cement concrete slab with basic unit it
Between gap thickness uneven, there is bigger randomness.Therefore for ensureing that space at the bottom of plate fills serosity, need to inject at serosity
Or even before solidification, four limits between concrete slab and basic unit are sealed, it is ensured that serosity is not revealed, and maintains certain grouting pressure；No
Then serosity can be from the relatively low boundary leakage of physical features at the bottom of plate, it is impossible to maintain certain grouting pressure, causes space less and distance note
Slurry hole remotely cannot fill.
Generally use the encapsulant such as sealing strip or foamed glue on four limits at the bottom of prefabricated cement board, fill up at the bottom of prefabricated cement board four
Space between limit and basic unit.Encapsulant plays effect and normally works, and needs to meet some requirements: the vertical support of generation
Power less than under the situation of concrete slab weights, needs to produce enough frictional force and side is born under hydraulic pressure do not produce sliding；Close
Closure material contacts dissimilar base material (may be pellet class, the steady class of water or soil matrix, surface structure is different with particle diameter), will not
Spillage；Serosity may be the types such as cement mortar, Colophonium, epoxy, and the viscosity of serosity, temperature, Acidity of Aikalinity are different, and encapsulant will not
Lost efficacy.In order to determine that encapsulant is the most feasible under the conditions of the use different at these, and determine the type of encapsulant, thickness
The factors such as degree, width and occupation mode, need assembled Identification Beneath Concrete Slabs sealing property when using encapsulant
Carry out strict test.
General performing leak test is mainly for situations such as door, window, automobiles, with assembled Identification Beneath Concrete Slabs
Use condition difference the biggest.Domestic current tightness measuring device and method of testing are not suitable for assembled cement-concrete road
Application scenarios at the bottom of panel.And the U.S., Japan and other countries are mixed field, earth road surface at assembled cement and encapsulant are widely used,
Different encapsulants be have employed for different operating modes, all have passed through strict test and screening.But its test device and
Method is in confidential state, researches and develops the sealing property testing equipment for assembled Identification Beneath Concrete Slabs and has the heaviest
The meaning wanted.
