Beijing Sany Heavy Machinery Co., Ltd successfully developed the first hydraulic tunnel pre-supporting construction equipment

SJ-180 Horizontal Rotate and Jet Drill is the new developed hydraulic pre-supporting construction equipment after close study of foreign and domestic advanced Horizontal Rotate and Jet Drill construction method. SJ-180 Horizontal Rotate and Jet Drill adopted imported parts in well-known international band such as engine, hydraulic system, electronic system, etc. SJ-180 Horizontal Rotate and Jet Drill owns such merits as double power sources, crawler walking, tighten structure, widely usage, long stroke of the power drive, fast implementation, coherent working procedure, high efficiency, auto monitoring of drilling angle, precise location, high accuracy, material saving, environment-friendly, problem solving ability(water blocking, sand-shifting preventing, ground subsidence preventing), and so on. The machine is mainly applied to underground pre-supporting construction of city subway, railway, highway, under water tunnel, underground passage, mine digging, etc. The machine is also used for foundation treatment and geological disasters prevention such as Treatment of soft foundation, anti-seepage curtain, Slope Anchorage, etc.

1、Power system: double power sources. CUMMINS diesel motor is responsible for walking and four supporting legs. Electric motor is responsible for other operations, and it is without exhaust gas pollution.
2、Travel system: steel crawler, hydraulic motor drive, suitable for variable ground conditions.
3、Hydraulic system: REXROTH high pressure variable pump, load-sensing hydraulic multi-road valve, electric proportion control.
4、Electric system: PLC central control, alarming function, electric shock protection.
5、Operation system: Main operation table is movable and separable; so long distance control can be realized. The screen can display depth, angle, location angle, rotary speed, rising and pressurizing speed, system pressure, flux, etc. Auxiliary operation table fixed in the front of the main body, equipped with engine gauge and travel operation handle.
6、Structural parts : Rotary table revolving mechanism and mast supporting mechanism assembled together realized tighten structure. Double arms supporting mechanism assures stability, avoiding the excursion. Mast is composed of three sections, convenient for transportation. Power drive owns double-level reduction function. The main axis adopts hollow structure, high output torque; 12m at one stroke.
7、Foldable crane is convenient for carrying worker to finish pit entrance operation.
8、Rotate and jet drill tool: Both one pipe and two pipes are fit in with power drive.
9、Grouting parameters monitoring equipment is in charge of all-time monitoring and recording of flux, pressure, etc, to ensure the quality of the construction.
10、Different drilling tools combination can undertake bolt, down-the-hole, rock drilling and so on.
