Description
Technical field
The present invention relates to the realm of building construction, shaping moudle structure and molding side more particularly to a kind of hardened slurry test specimen
Method.
Background technique
Because underground impervious wall have structure is reliable, Construction Vibration is small, low noise, can be few etc. close to architecture construction, land occupation
Advantage is widely used in dyke seepage control engineering.But using the rigidity such as armored concrete, plain concrete, flyash concrete
The cut-pff wall that material is built, because its elasticity modulus and dykes and dams itself or its ground difference are very big, the sedimentation of dykes and dams or sinking for ground
It falls into and displacement keeps rigid antiseepage coping subject to large compressive, side is caused in cut-pff wall by very big frictional force
The stress ratio rigid concrete strength of materials is high, and strain is also bigger than the limiting strain of rigid concrete material, and leakage proof wall is caused to produce
Raw crack, reduces anti-seepage effect.
To solve the problems, such as that rigid cut-pff wall exists, using flexible material such as plastic concrete, self-hardening slurry and solidifying ash
Slurry etc. is built cut-pff wall and is gradually increased.Their modular ratio rigid concrete is much smaller, can preferably adapt to the change of ground
Shape greatly reduces the intracorporal stress of wall, avoids the cracking of wall.Wherein hardened slurry refers in built slot, with shield
Wall mud is basic slurry material, is added the curing materials such as cement, waterglass, flyash wherein, it is agitated uniformly after solidify
Low strong, the low bullet of one kind and the biggish flexible material of limiting strain.Compared with plastic concrete, hardened slurry can pass through tune
Whole proportion can select required intensity, setting time and mechanical performance index in the larger context, with self-hardening slurry phase
Than setting time is not influenced by the pore-creating time.
Building underground impervious wall using hardened slurry has that construction is simple, that work efficiency is fast, labor intensity is low, cost is small etc. is excellent
Point, but the preparation of hardened slurry and the ununified regulation of test specimen sampling test, standard, can only refer to existing concrete at present
Test preparation carries out, and the shaping mould of hardened slurry test specimen is all made of 15cm × 15cm × 15cm assembled swage or integral type modeling
Expect the round integrated plastic mould of mould or 15cm diameter, 15cm high.Since hardened slurry is a kind of fluent material, water consumption is big,
When being formed using assembled swage, the water in hardened slurry can be flowed out from the seam gap of assembled swage, make hardened slurry
The ratio of mud changes and testing result is caused to be distorted, and such as serious dehydration, which will cause test specimen and collapse, leads to not form.Due to solidifying ash
After slurry consolidation test specimen bullet mould it is low it is deformable it is big, intensity is low easily broken, using integrated plastic mold forming, when being pressed into gas demoulding,
When pressure is small, test piece deformation is not easy, and when pressure is big, test specimen is easily broken.Therefore, existing concrete formation mould is difficult to full
The forming requirements of sufficient hardened slurry test specimen are less able to satisfy hardened slurry Detection of Stability and require and simulate hardened slurry construction work
Skill test requirements document.
