Description

Cylindrical test piece preparation all-in-one of inorganic binder stable material

Technical Field

The utility model belongs to the technical field of highway engineering detection, and particularly relates to an integrated machine for preparing a cylindrical test piece of an inorganic binder stabilizing material.

Background

The inorganic binder stabilizing material is prepared by mixing a proper amount of inorganic binder (such as cement, lime, fly ash and other industrial waste residues) and water into crushed or undisturbed loose soil, uniformly stirring, compacting and preserving to obtain the composite mixture with strength, stability and other requirements. The composite material has the characteristics of good mechanical property, high strength, good stability and the like, and is widely applied to a base layer and a subbase layer of a pavement structure in highway engineering construction.

When the quality of the inorganic binder stabilizing material is evaluated by the current standard of the highway engineering construction industry in China, a formed cylindrical test piece is generally adopted to measure the unconfined compressive strength, and whether the road performance of the mixture is good or not is checked. At present, the existing test rules of inorganic binder stabilizing materials in highway engineering provide that the cylindrical test piece of the inorganic binder stabilizing materials can be used for testing unconfined compressive strength, indirect tensile strength, indoor compressive resilience modulus, dynamic modulus, splitting modulus and the like.

In the prior art, the conventional method for forming the cylindrical test piece of the inorganic binder stabilizing material is as follows: (1) Determining an optimal moisture content and a maximum dry density of the stabilizing material; (2) Determining specific water adding amount and inorganic binder adding amount according to the water content of each component material; (3) Preparing materials according to the material proportioning design, placing the weighed soil in a rectangular disc (about 400mm multiplied by 600mm multiplied by 70 mm), and adding water into the soil for uniform mixing; (4) Placing the sample in a closed container or a plastic bag for soaking for standby; (5) After the soaking time is reached, the inorganic binder is mixed into the soaked soil for uniform stirring again, and the mixture is uniformly filled into a cylindrical test mold in batches; (6) Pressing the upper cushion block and the lower cushion block into a test die by using a press at a loading rate of 1mm/min, maintaining the pressure for 2min, and unloading; (7) And (5) demolding, weighing and recording the test piece, putting the test piece into a plastic bag for sealing, and then moving the test piece to a curing room for curing.

In the process, when test preparation is carried out, at least 6 test pieces are required to be prepared for stabilizing fine-grained soil of the inorganic binder, at least 9 test pieces and 13 test pieces are required to be prepared for stabilizing fine-grained soil and coarse-grained soil of the inorganic binder respectively, and a plurality of test pieces are required to be molded in one test. The coarse-grained soil test piece with wider application in the test sample has the weight of about 6000g and more materials, firstly, a tester is required to mix the mixture manually during the preparation of the test sample, the mixture is difficult to mix uniformly, and the mixing uniformity is larger due to different personnel, so that the accuracy of the test is reduced; and most of manual mixing is open mixing, and a large amount of dust generated in the mixing process is sucked into a human body, so that the physical health of test personnel is seriously harmed. Secondly, most of the used test molds are made of steel casting materials, the weight is large, and in the whole process of the workpiece, the test molds for loading the samples need to be manually carried in a reciprocating manner to be lifted and lowered. Because the test pieces are more in number and weight, a plurality of people are required to complete work of the workpiece, a large amount of manpower, material resources and time are consumed, certain dangers exist in test operation, the test pieces are easy to damage, and the test efficiency is low. Again, manual sample stripping is also a difficult problem, with some sticking in the test pattern being difficult to remove.
