Abstract
The utility model discloses a leapfrog-type drilling device comprising a leapfrog-type tamping machine. An erection support is welded with bottoms of leg columns of the leapfrog-type tamping machine. Screw holes are formed in the erection support, screw holes corresponding to the screw holes in the erection support are formed in a fixed support, bolts respectively penetrate through the screw holes in the erection support and the screw holes in the fixed support to fixedly combine the erection support and the fixed support into a whole, and a pore opening device is welded on the lower portion of the fixed support. The leapfrog-type drilling device is simple in structure, convenient to use, and capable of drilling large quantities of pores in the upper surface of a spring soil area in short time, thus facilitates the practice that a constructor fills water in the spring soil area to adjust humidity, and carries out tamping operation again.
Description
Technical field
The utility model relates to engineering machinery processing and manufacturing field, is specifically related to a kind of Leapfrog type drill.
Background technology
Proportioning and humidity requirement to tabia in the process of backfill tabia are comparatively strict, but the phenomenon of spring Tu Qu still can appear occurring because humidity is lower in the operating process of reality, not only can seriously influence the stable of ground, and also can further affect the sedimentation of building after moulding, in order to address this problem, current way is to adopt the interior tabia in spring soil district is all dug out mostly, and the method for backfill again, not only take time and effort and incur loss through delay the valuable construction period, and or can't tackle the problem at its root the place.
The utility model content
The utility model purpose is to provide a kind of Leapfrog type drill, and it can solve existing problem in background technology effectively.
In order to solve existing problem in background technology, it comprises the Leapfrog type tamping machine, the leg column bottom of this Leapfrog type tamping machine is welded with erection support, offer screw on this erection support, and offer the screw corresponding with it on fixed bearing, bolt passes respectively to be fixed after screw on erection support and fixed bearing and is integral, and is welded with boring device below described fixed bearing.
Described boring device is comprised of the pin post that is arranged in below erection support.
Described boring device is for cutting native cutter, and this cuts native cutter whole is sector structure.
Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to use, can leave a large amount of pores at the upper surface of spring Tu Qu within a short period of time, thereby can the convenient construction personnel regulate humidity to the interior water filling in spring soil district, and carry out tamping operation again.
Description of drawings
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is done simple introduction.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment is clearly and completely described the technical scheme in the utility model embodiment.
Referring to Fig. 1, this specific embodiment is to be achieved by the following technical solutions, it comprises Leapfrog type tamping machine 1, the leg column bottom of this Leapfrog type tamping machine 1 is welded with erection support 2, offer screw on this erection support 2, and offering the screw corresponding with it on fixed bearing 3, bolt 4 passes respectively to be fixed after screw on erection support 2 and fixed bearing 3 and is integral, and is welded with boring device below described fixed bearing 3.
Described boring device forms by being arranged in erection support 2 following pin posts.
Described boring device is for cutting native cutter, and this cuts native cutter whole is sector structure.
Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to use, can leave a large amount of pores at the upper surface of spring Tu Qu within a short period of time, thereby can the convenient construction personnel regulate humidity to the interior water filling in spring soil district, and carry out tamping operation again.
