Description
Technical field
The present invention relates to a kind of grouted-aggregate concrete column test piece mould, belong to field of civil engineering.
Background technology
Grouted-aggregate concrete refers to and adopts without pressure or the mode having pressure (also referred to as slip casting), slurries is poured into the concrete formed after sand, stone etc. gather materials.Because the column test piece mould of routine is when pouring into slurries, mould is uncovered, and the making state that test specimen two ends concrete experiences exists difference, can have an impact to result of the test; Conventional column test piece mould is not closed, can not real simulation pressure grouting; For the situation that slurries expand when being in the milk or after grouting, conventional column test piece mould is inapplicable; All the more so to high-expansion slurries.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of grouted-aggregate concrete column test piece mould.This mould has seal, not spillage during mud jacking, and after the demoulding, surface of test piece is smooth, and before test, polishing workload is very little.
For solving its technical problem, scheme of the present invention is: provide a kind of grouted-aggregate concrete column test piece mould, the composition of mould comprises equiform base and die cover, the same and the sheet matrix that is semicircular in shape inside cross section of two shapes, several clamping screw, the cylindrical diameter of inner institute and test specimen equal diameters after two matrix clamping screw combinations wherein, and claim this assembly for assembly first, assembly and be called secondary assembly with being provided with after the base combination of slurry assembly first, secondary assembly is after the die cover of mounting strap pressure sensor assembly and pulp assembly, form complete mould.When mud jacking, except slurry-feeding hole and controlled slurry outlet, whole set of die is sealing.
Mould cross section is hexagon or cylindrical.
Further, base and mould are stamped a circular trough lower than surrounding, and assembly is circular in end outer surface first, surrounding can put into closely connectedly, claim this groove to be locating slot.
Further, matrix surrounding is carved with continuous print sulculus, can place elastic rubber band, mutually pushes against and pushes against rear joint seal with base or die cover.
Further, base and die cover respectively there is a tapped hole, the assembly of mould also comprises the slurry-feeding hole assembly of an end band external screw thread and slurry-inlet valve door simultaneously, with the slurry outlet assembly of an end band external screw thread and pulp valve, structure and the grouting lance end at the grouting mouth place, outside of slurry-feeding hole assembly are supporting.
Two matrixs can without seal groove in its end, and corresponding seal groove is engraved in the locating slot bottom margin place of base and die cover.
Further, along height of specimen direction, only on a matrix, there is seal groove.
Further, in die cover except slurry outlet, also has one for installing the hole of miniature pressure cell.
Further, assembly three cover locking bolts connect first, wherein a set of centre position being positioned at length direction, another two covers are arranged symmetrically in two-end part, respectively there are two cover locking bolts the end of the assembly first of base, die cover and correspondence, they are symmetrical in central distribution, are connected with the centre position of matrix end.
Further, each matrix is axially having continuous print sulculus, and another side leaves convex stupefied, and is carved with continuous print sulculus near periphery in the locating slot of base and die cover, and all little groove bottom have one deck sealing gasket.
The using method of described grouted-aggregate concrete column test piece mould: first two matrix clamping screws are connected, again be installed into the base starching assembly and be connected, vertical placement, pour in cylinder and gather materials, remove and exceed gathering materials of nozzle, die cover with pressure sensor assembly and slurry outlet assembly is installed, tester starts to read pressure sensor data by certain frequency, open slurry-inlet valve door and pulp valve, start grouting, after having slurries to flow out from pulp valve, close pulp valve, continue mud jacking one minute, close slurry-inlet valve door, after waiting for specimen molding, open each clamping screw, mold disintegration, test specimen stripping forming.
The invention has the beneficial effects as follows: provide a kind of column test piece mould being mainly used in grouted-aggregate concrete, during being specially adapted to be produced on mud jacking, slurries just have the grouted-aggregate concrete column test specimen of high-expansion, each establishment of component is simple, assembling and dismounting are easily, clamping screw and locating slot are all conducive to accurate location, sample dimensions precision is high, and shaping test piece end face is smooth, and before specimen test, polishing workload is very little.
