Technical field
Background technology
At present, the many big cities of China have all begun the exploitation of the large-scale underground space, as subway, underground utilities, market place builet below the ground etc., various tunnel construction machinerys have obtained using widely, but because the complexity of geological conditions, generally need in tunneling process, adopt to excavation face and pressure chamber injection bubble and carry out soil body improvement, ensure carrying out smoothly of engineering construction, reduce construction cost; On the other hand, in present building, hydraulic engineering construction, light materials such as bubble light-weight soils, foam concrete are used because of the less advantage of its deadweight, and the production of these light materials is by mixing bubble and other materials processing forms in the timber.
The bubble that relates in the above-mentioned engineering all needs a kind of bubble foam device, at present the domestic special foam device that also is not applicable to these aspects.The present invention fills up domestic blank in these areas at present just.In addition, in carrying out the experimental study relevant with bubble, required bubble only can obtain by the interim foaming in scene, and this device can pass through simple size transformation, is applied to the production of the required bubble of experimental study.
Summary of the invention
The purpose of this utility model is the problem at above-mentioned existence, develops the practical bubble foam device of a kind of geotechnique, carries steady air flow by air compressor machine or pressurized tank, as the source of the gas of bubble formation and the motive force of bubble formation; Use volumetric infusion pump control infusion flow, foaming agent solution is transported to the foam gun afterbody from storage container, and mix in compressed air carries out the short time, by the stratum reticulare of foam gun front portion, just form the tiny bubble of a large amount of homogeneous at last then.The technical scheme of this device: its structure is the delivery outlet of the input port sending and receiving infusion solution container of volumetric infusion pump, and the delivery outlet of volumetric infusion pump connects one-way cock, flowmeter successively, joins with an input port of foam gun; The delivery outlet of air compressor machine or pressurized tank connects pressure regulator valve, one-way cock, flowmeter successively, joins with another inlet of foam gun.The advantage of this device: owing to used volumetric infusion pump and flowmeter, can rationally control the proportionate relationship of gas-liquid, produce the bubble of multiple different in kind by regulating foaming agent solution and compressed-air actuated flow; Owing to used pressure regulator valve, can rationally control the pressure of gas, guaranteed characteristics such as bubble uniformity, stability.Can satisfy the needs of different engineerings.
