Description
Technical field
The utility model relates to building field, is the concrete permeability pick-up unit.
Background technology
Concrete has been able to widespread use in engineering construction since coming out.But because people generally emphasize concrete intensity, and ignored the permanance of material, paid heavy cost, caused tremendous loss for many countries, and this loss has been the gesture of rising day by day for repairing and change the building of damaging.Along with concrete widespread use, concrete permanance becomes the key issue of concrete design the inside.Concrete durability can adopt evaluations such as frost resistance, impermeability, anti-carbonization aggressivity, precenting chlorate corrosion, resistance to abrasion, above-mentioned character is all directly related with concrete density basically, concrete density has determined concrete perviousness, we can say that therefore perviousness is a key factor of decision concrete durability.
A lot of hydraulic structures and industry, civil building all have corresponding requirements to its concrete anti-permeability performance.Carry out the purpose of concrete impermeability test,, or measure the infiltration height of concrete under constant water pressure to calculate its relative coefficient of permeability exactly in order to measure concrete anti-permeability performance, label.China's National Standard Standard for test methods of longterm performance and durability of ordinary concrete " (GBJ82) adopt the anti-penetration grade method to test concrete impermeability, with the back cut diameter is 175mm, lower port diameter is 185mm, high 150mm truncated cone-shaped test specimen or following diameter and height are 150mm cylinder examination body, one group of 6 test specimen, apply 0.2MPa hydraulic pressure from examination body bottom and begin test, increase hydraulic pressure 0.1MPa every 8h, in 6 test specimens, there are 3 to be penetrated by press water, stop test, with in every group of 6 test specimens 4 find no the maximum hydraulic pressure of infiltration during phenomenon and be called concrete anti-penetration grade; And concrete impermeability test device therefor should meet the following requirements: concrete impervious instrument should be able to make hydraulic pressure system in accordance with regulations stably act on device on the test specimen; Pressue device spiral or other form, its pressure is advisable test specimen being pressed in the specimen sleeve.
It is simple, directly perceived adopting the mode advantage of measuring anti-penetration grade, so this method is widely-used at building field, but existing impermeability test machine can only be tested one group of test specimen, and the collection that incompatible many now groups are tested proportionings and great number tested data needs.
The utility model content
The technical problems to be solved in the utility model is, deficiency at the prior art existence, design the concrete impervious pick-up unit of a kind of many group test specimens, it is suitable for the test of many group test proportionings and the collection of great number tested data, and has easy, the energy-saving and cost-reducing characteristics of operating procedure.
The technical solution of the utility model is, the concrete impervious pick-up unit of described many group test specimens comprises the die trial group of being made up of six die trials, each die trial is communicated with divider through the operation valve and the pipeline of correspondence respectively, its design feature is, described die trial group has three groups at least, the divider of each die trial group connected with water tank through communicating pipe, and the water inlet of this water tank links to each other with inlet water tank by the road and be serially connected with water pump in described pipeline.
Below the utility model made further specify.
Referring to Fig. 1, the concrete impervious pick-up unit of many group test specimens described in the utility model comprises the die trial group of being made up of six die trials 12, each die trial 1 is communicated with divider 4 through the operation valve 3 and the pipeline of correspondence respectively, its design feature is, described die trial group 2 has three groups at least, the divider 4 of each die trial group 2 connected with water tank 5 through communicating pipe, and the water inlet of this water tank 56 links to each other and be serially connected with water pump 8 in described pipeline 6 with inlet water tank 7 by the road.
Described water tank 5 can be provided with safety valve 9 and water-filling nozzle 10 that is positioned at the tank body top and the faucet 11 that is positioned at tank base.
The utility model device is to utilize airtight container and equate (ignoring head disregards) with the pipe system pressure everywhere of its connection, exerts pressure with water pump, and the easy device that keep-ups pressure and test within the limits prescribed; It drags water pump with motor and exerts pressure, and by pipeline and water tank, operation valve, is transported to each die trial (sample system) then and carries out load test.After test specimen was installed in each die trial, when operation valve is opened, ducted hydraulic pressure promptly loaded test specimen greater than the atmospheric pressure of outside.
This device can carry out the test of many group test specimens simultaneously, has saved resource; When carrying out many group specimen tests, it is more approaching to many test condition of an Anti-leakage instrument by the test condition of same control system control than usefulness, and comparability is more arranged; Because the time of impermeability test is longer, this device can be organized (as three groups or more groups) test more and carry out together, has saved test period, can access more data in the identical time; Can be by the many groups of a control system control test specimen, the flow process that simplifies the operation has been saved the cost of control system.
As known from the above, the utility model is the concrete impervious pick-up units of a kind of many group test specimens, and it can control the test of three groups or three groups above test specimens simultaneously, adapts to the collection of present great number tested data and the test of many group test proportionings, the plant operator skill is easy, has saved available resource.

Embodiment
As depicted in figs. 1 and 2, the concrete impervious pick-up unit of many group test specimens described in the utility model comprises the die trial group of being made up of six die trials 12, each die trial 1 is communicated with divider 4 through the operation valve 3 and the pipeline of correspondence respectively, described die trial group 2 is three groups, the divider 4 of each die trial group 2 connected with water tank 5 through communicating pipe, and the water inlet of this water tank 56 links to each other and be serially connected with water pump 8 in described pipeline 6 with inlet water tank 7 by the road.
Described water tank 5 is provided with safety valve 9 and water-filling nozzle 10 that is positioned at the tank body top and the faucet 11 that is positioned at tank base.
Described water pump can be designed to 12 controls of controlled system, and the pressure signal of the tensimeter of installing on the water tank 5 13 is sent to control system 12.
In this device, frame adopts shaped steel to be welded, and pin is gone up the thick steel plate pallet of 1.5mm above, with the bolt of M10 die trial seat pallet is fixed on the carriage.Die trial is connected by being spirally connected of M12 with the die trial seat, and middle " O " shape rubber ring that adopts seals, and test specimen is encapsulated in the die trial after with pig iron mold forming, and the hexagonal socket wrench of special use is adopted in fastening die trial.
Divider and operation valve are installed concentratedly in the display instrument front, mainly are the water route circulations of six test specimens of control (examination body) or end.
Water pump drags with the 90W motor, can pass through the two poles of the earth gear change, drives the excentric shaft rotation.And then, order about pump plunger and move reciprocatingly and carry out work by guide pillar and connecting rod.Because the flow of water pump is very little, what therefore can be similar to thinks that the hydraulic pressure of supplying with the examination body is for static.
Water tank is the tun that has the retaining energy storage and can play the pulse action that reduces press water.Use the annex funnel before the test, water is injected water tank, after test finishes, water in the jar is drained by faucet by water-filling nozzle.
Instrument for automatic control adopts the electric control system of existing impervious instrument.
