Description

The slotting through hydraulic pressure submerged membrance machine

The utility model relates to civil engineerings such as civil engineering machinery, particularly anti-seepage reinforcing and slots, buries the slotting through hydraulic pressure of film and bury film device.

In recent years, carry out in the protective reinforcing of supporting, antiseepage, hydraulic engineering and Environmental Engineering of deep foundation ditch in civil engineering, adopt widely and construct diaphragm wall, use more as high pressure jet grouting, slot into job practicess such as wall, board-like grouting, but the common drawback that they all exist is the cost height, work efficiency is low, anti-seepage effect is constructed and geological conditions influences very greatly, and quality be difficult for to guarantee.Be accompanied by the continuous development of chemical fibre industry, the continuing to bring out of geosynthetics various forms product, be applied on the engineering scope more and more widely.By experimental study and application, occurred a kind of the vertical shop of anti-seepage geomembrane being gone into to form in the groove continuously or the leakage preventing structure of sealing, produce a kind of new technology of seepage failures such as stream soil, piping in order to prevent ground and building.Because of having, it has a extensive future, good seepage-proof property, and speed of application is fast, easy to operation, advantage such as cheap has been subjected to paying attention to and using, the groove equipment of making that various types successively occurred is as The trench saw, chain type, jetting open flume type, rotary, reciprocating type, forced etc.By facts have proved, rotary and forced to make the groove equipment scope of application narrow, and work efficiency is low, is eliminated; The jetting open flume type is made groove equipment must sufficient water condition, and construction environment is had pollution and destruction etc.; Use more chain type, kerf formula and the reciprocating type groove equipment of making of mainly containing, but the equipment of these three kinds of patterns is according to being suitable for geological conditions, making the groove depth difference, its pluses and minuses are respectively arranged, as reciprocating type complicated with kerf formula construction control, mechanicalness noise is big, vibration is big, also very big to the stabilizing influence of notch; Chain type is made groove equipment heaviness, and mobility is poor, and the fluting radius of curvature is big, has all limited these plant equipment exploitations, promotion and application, demands urgently improving.

The purpose of this utility model is at above technical deficiency, provides a kind of hydraulic drive, stepless adjustment to cut soil pressure and cutting speed, spread film, the automatic slotting through hydraulic pressure submerged membrance machine of controlling continuously, satisfies construction requirements such as civil engineering anti-seepage reinforcing.

The slotting through hydraulic pressure submerged membrance machine, form by reinforcing part, slotted section and shop membrane portions, comprise headstock 1, afterburning car body 10 and plastic film axle 17 etc., but it is characterized in that afterburning car body 10 upper liquid pressing tongs 9 clamping rails 19, connect slotting through hydraulic pressure car body 7 by walking oil pressure cylinder 8; Put hoist engine 6 and pylon 11 on the slotting through hydraulic pressure car body 7, lifting pit saw 12: fuel tank 5 is by motor 23, fluid motor 27 control headstocks 1, put connecting rod 4, connecting lever 3 and balance iron 2 on the headstock 1, for pit saw 12 provides power, be provided with feed pipe for mortar 31, scum pipe 32 in the pit saw 12, feed pipe for mortar 31 connects the mud machine 29 that stirs by slush pump 16, and scum pipe 32 connects sand pump 30; Slotting through hydraulic pressure car body 7 rear portions are connected with shop film car body 13, put switchbox 15, hoist engine 14 and slush pump 16 on the shop film car body 13, and afterbody is provided with pylon 18, lifting plastic film axle 17.

This machine operating principle is: the motor drives oil pump also passes through headstock, crank-link mechanism moves reciprocatingly saw blade in groove, slush pump pumping mud shotcrete pipe ejection from saw blade simultaneously, die-cut soil layer, flushing sawtooth and retaining wall, sawtooth cuts the ground and the aqueous mixtures that get off, scum pipe from saw blade is discharged in the groove of having completed film outside the groove or, meanwhile oil pump is to afterburning car fuel feeding, afterburning car hydraulic tongs clamping rail is also fixing, the oil cylinder oil extraction, apply counter-force for the fluting car, the drive fluting apparatus is advanced, and then form continuous groove, and spread film device simultaneously and fluting apparatus is synchronized with the movement, the plastic film axle rolls in groove, the smooth shakedown of plastic film is gone in the groove that become, forms continuous underground antiseepage structure.

The utility model is reasonable in design, and control is convenient, and the automaticity height mainly shows: 1. main frame adopts hydraulic transmission technology, and soil pressure and cutting speed are cut in stepless adjustment; 2. operation is light, and the automaticity height reaches automatic control substantially under the nominal situation; 3. bury film and adopt shop membrane technology continuously, seam is few, and quality is easy to guarantee; 4. work efficiency height, integrated cost is low, and the scope of application is extensive, is easy to application.
