The material is semi-rigid in characteristic, is mainly used for building higher-grade roads and is often used in the forming process of base courses and sub-base courses of the road surfaces of the higher-grade roads. Compared with common soil, the stabilized soil has stronger stability, and is formed by adding proper parts of materials such as lime, cement, industrial waste residue, asphalt and the like into loose or crushed soil (including common coarse, medium and fine soil), and mixing, stirring, compacting and maintaining according to reasonable proportion to obtain a novel soil material with better stability. The inorganic binder stabilizing material is classified into a cylindrical shape and a beam shape.
In the forming process of the beam-type test piece made of the inorganic binder stable material, the used test mold is made of cast iron, the inner surface of the test mold is polished, and the test mold is convenient to assemble and disassemble, as shown in figure 1. The forming process of the beam-shaped test piece is as follows: putting the lower pressing block of the test mold into the lower part of the test mold, brushing oil on four sides of the baffle plates on two sides, paving paper with the same size as the base plate, pouring the mixture into the test mold, slightly and uniformly inserting the mixture into the test mold by using a tamping rod, aligning the upper pressing plate to the mixture, putting the mixture on the mixture to enable the mixture to be exposed for about 2cm, finally putting the whole test mold (together with the upper pressing block and the lower pressing block) on a press machine, and pressurizing until the upper pressing block and the lower pressing block are pressed into the test mold. However, when the test mold is stressed, the mixture is extruded towards two sides, and after the beam-type test mold is used for many times, baffles on two sides of the test mold are slightly bent and deformed, so that the compaction degree of a formed test piece is insufficient, the test piece is easy to loosen, and the experiment generates errors; when the upper pressing plate is placed, the upper pressing plate needs to be aligned with the inner diameter of the test mold in a front-back mode, manual operation errors often occur, the upper pressing plate is not placed properly, compaction failure is caused, and the mold is easy to damage; the existing test die can not meet the standard and the upper and lower pressing plates are exposed for 2 cm.

the utility model provides an inorganic binder beam type examination mould of preapring for an unfavorable turn of events shape, comprises bounding wall part, clamp plate part and bolt part, and the bounding wall part includes inner baffle, outer baffle and interior baffle, the outer baffle inboard is equipped with positioning groove, and the clamp plate part includes top board and holding down plate, the top board includes top board main briquetting, side direction picture peg and location lug, side direction picture peg thickness is double-deck distance between the baffle, adds on the side direction picture peg and is equipped with spacing line, and spacing line is 2cm above the iron plate, the holding down plate sets up to semi-circular tenon structure, comprises lower clamp plate main briquetting, left picture peg and right picture peg, the bolt comprises screw rod, spacing nut, fixation nut, and the width of spacing nut is double-deck distance between the baffle.
The inner side of the outer clapboard is provided with a positioning groove.
The upper press plate comprises a main press block part, a lateral inserting plate and a positioning lug.
And a limiting line is additionally arranged on the lateral inserting plate, and the distance between the limiting line and the upper side of the iron plate is 2 cm.
The lower pressing plate is of a semicircular tenon structure.
Compared with the prior art, the utility model has the advantages that:
the baffle is thickened on the basis of a conventional test mold, so that the baffle is prevented from deforming, the upper pressing plate is placed without manual alignment, the test error is reduced, and the standard requirement that the upper pressing plate and the lower pressing plate are exposed by 2cm can be met.
