The device has changed the operation of artifical sealing wax in the past, can accord with concrete impermeability test's the requirement of standardizing with sealed totally to the side of the test block, tests the efficiency that has improved the experiment of big batch through extracting 4 samples simultaneously.
Description
Technical field
This utility model relates to the sealing device of a kind of concrete impervious instrument test block, specifically a kind of for concrete impermeability test time test block side seal device that concrete test block side is sealed.
Background technology
Traditional concrete impervious instrument, need to by test block side and die trial by sealing with wax or other cohesive materials seal when carrying out impermeability test, it is prevented that water permeates from test block side.This method troublesome poeration, pollutes big, and leakage efficiency is very low, is a link of difficulty the most in concrete impermeability test.
When high-volume carries out impermeability test, substantial amounts of test block test consumes substantial amounts of time and the energy, inefficiency.
Summary of the invention
In order to overcome prior art Problems existing, the purpose of this utility model is to provide a kind of test block side seal device for concrete impervious instrument, this device compresses leather sheath by high pressure, it is achieved that the test block seal means of efficient quick, greatly reduces the workload of test preparatory stage.
The purpose of this utility model is achieved through the following technical solutions:
A kind of test block side seal device for concrete impervious instrument, it is characterised in that: this sealing device includes upper cover plate, lower cover, testing base, leather sheath and housing, and described leather sheath and housing, upper cover plate and lower cover constitute the cavity placing test block sealed；Upper cover plate be arranged on housing upper and with housing compact siro spinning technology, lower cover be arranged on lower housing portion and with housing and testing base compact siro spinning technology；Sealing ring it is provided with between lower cover and testing base；Housing is provided with water under high pressure water filling port and water under high pressure water filling port is positioned at outside leather sheath.
Further, being provided with several again stations of 4 on impermeability test platform, each station is furnished with one and seals die trial.Water under high pressure water filling port is arranged on lower housing portion.
Leather sheath is arranged between case inside and test block, and the upper end of leather sheath is tightly fastened by upper cover plate and housing, and the lower end of leather sheath is tightly fastened by lower cover and housing.
In this utility model, the pumping plant of central control system supplies hydraulic pressure to sample and sealing die trial respectively, and a road hydraulic pressure is used for sealed test piece, and another road hydraulic pressure is used for the pressure producing test requirements document to sample
According to impermeability test code requirement, often group test block is 6, occurs that the test of 3 seepage then these groups is judged to defective in one group, on the contrary then this group pass the test.During due to high-volume test, disqualification rate is generally below 10%, therefore often organize 4 extracted in 6 samples during our bulge test to test, if four all qualified, without doing residue two again, can determine whether that reorganization test block is qualified, if 4 there is seepage, then again this group sample is carried out qualified judgement by remaining after two test blocks individually detect, so substantially increase work efficiency, and save the energy.For the multiple that the station quantity of this impervious workbench is 4, compare traditional impervious workbench and often organize 2 stations of minimizing, also reduce the cost of equipment.
Leather sheath upper and lower opening is sealed in the groove of the upper and lower opening of die trial cylinder body by the upper and lower cover plates of die trial, leather sheath and die trial cylinder body form airtight cavity, inject water into cavity by water filling port, and in addition high pressure, leather sheath is pressed in test block side to test block lateral expansion, plays sealing function.Leather sheath adopts flexible material to make, and has certain elastic force, and wear-resisting pressure.
Compared with prior art, this utility model has the advantage that test block can be directly placed into die trial, open water filling port valve and water under high pressure is injected leather sheath chamber, die trial side, eliminate over and need to adopt the sealing course of processing of methods such as sealing with wax, after off-test simultaneously, the demoulding is simple and quick, substantially increases work efficiency.
