Description
Technical field
The present invention relates to a kind of percussive drill flatcar of impervious wall construction and control the method for percussive drill impervious wall construction precision, being adapted to the ultra-deep impervious wall construction adopting percussive drill to carry out more than 70 meters especially.
Background technology
When adopting percussive drill to carry out impervious wall construction, the unit groove section due to impervious wall is slotted hole, and rig needs just can complete construction task along impervious wall axis direction is often mobile.In order to meet impervious wall construction needs, generally adopt the lumps of wood and track to lay percussive drill platform in the side of impervious wall axis, platform is installed the flatcar for percussive drill, and be placed in by percussive drill on flatcar, rig carries out impervious wall construction on flatcar.Flatcar not only to withstand shocks drilling machine construction time the load that produces, also want to reciprocate along drilling machine platform simultaneously.Traditional flatcar adopts 2 die squares, 4 little lumps of wood and wheel horse and is processed into, die square is of a size of 40cm × 40cm × 400cm, as longeron, the little lumps of wood is of a size of 15cm × 15cm × 150cm, as crossbeam, between die square and the little lumps of wood, adopt the bolt of ∮ 16 to connect, 4 wheel horses are installed below the little lumps of wood, and be connected with the little lumps of wood, flatcar is walked on the track of drilling machine platform by wheel horse.At present, percussive drill develops into ZZ-6A type from CZ-22 type, and drilling tool quality develops into 5t by 1t, and the one-tenth wall degree of depth of impervious wall is more than 100m, and the load that in impervious wall construction process, rig produces is increasing.Adopt traditional flatcar to carry out impervious wall construction, have the following disadvantages: the load that (1) drilling machine construction produces is increasing, and flatcar is difficult to bear upper load, easily damages; (2) between the lumps of wood of flatcar and with bolts between the lumps of wood and wheel horse, easily deform in the process of movement, cause flatcar to derail, rig capsizing case occurs.
For ultra-deep impervious wall, in order to ensure continuity and the verticality of grooving, need, by increasing impervious wall excavation face, for moving horizontally apart from long percussive drill, often to there will be bending antiseepage wall chase.
Summary of the invention
In order to overcome traditional rig flatcar to the deficiency of impervious wall construction, technical problem to be solved by this invention is to provide a kind of percussive drill simple to operate, esy to use, safe and reliable construction flatcar, in addition, by repeatedly revising the horizontal level of drilling tool, improve percussive drill impervious wall construction precision.
The technical solution adopted in the present invention is: a kind of percussive drill flatcar of impervious wall construction, percussive drill comprises cramp bar, auxiliary rod, drive motors, auxiliary rod top is connected to cramp bar upper end, pulley is established on cramp bar top, the steel cable of traction drilling tool is connected by pulley drive motor, percussive drill flatcar comprises mobile platform and is located at the percussive drill of front end in mobile platform, mobile platform rear end is provided with counterweight, mobile platform lower end is provided with movable pulley and support component, and described support component can make the movable pulley of mobile platform and ground be separated.
Further, mobile platform lower end is provided with multiple support component, and what be located at mobile platform front end is front support parts, and what be located at mobile platform centre is middle support component, and what be located at mobile platform rear end is rear support parts;
Described front support parts are located at cramp bar and mobile platform connection, and described middle support component is located at auxiliary rod and mobile platform joint, and described rear support parts are located at mobile platform counterweight pressure confined area.
Further, front support parts, middle support component, rear support parts are pneumatic actuation parts, and front support parts, middle support component, rear support parts are electrically connected with controller respectively.
