Abstract
An excavation machine for harden ground solves the problems of the pace of progress of prior excavation machines is slow, it is difficult to raising efficiency, and the resulting problem of project cost is rising dramatically. The invention uses the upper domes structure which is preposed on the caterpillar bulldozer, size is from small to big along the front to rear and lateral section is triangle to comprising the pavement excavation machine, so the harden layer splits quickly and we get faster excavation speed. The excavation machine is widely used in large area ground reconditioning such as municipal road and airport.
Description
Technical field
The present invention relates to the backactor of harden ground such as a kind of road breaking machine, especially cement.
Background technology
Present road surface excavation is to adopt pneumatic hammer, throw hammer etc. and pulverize the back excavation, and tempo is slow like this, and efficient is difficult to improve, and causes construction costs to rise significantly thus, and this influences economic worth that road rebuilds and social benefit.
Summary of the invention
Task of the present invention is that to design speed fast, the economical pavement digger that efficient is high.
The present invention is that the ascending cross section in preposition front and back is that triangular form arch structure is formed pavement digger on the employing crawler type promotion machine.Because the structure that hardens that intensive treatment such as the pitch on ground or cement and reinforcing bar form, if destroy on the surface that tension force is big, need the too many energy of waste, our slave plate is forged the comparatively soft real layer of raising that does not harden of face and is started with, adopt comparatively big thrust to arch up from the real layer of raising, the piece that hardens on road surface will be started and be divided like this.
Arch structure in the employing can make the hardening layer on road surface divide rapidly, obtains to excavate faster speed.
The specific embodiment
During concrete enforcement, last arch structure can imitate twin wrest formula structure, and the piece that hardens that arches upward like this can be taken advantage of a situation and be routed up, and does not so just influence the pace of backactor.If the road surface is a two-way traffic, can arch up the easier like this realization block splitting that hardens when constructing simultaneously from middle position.
In the triangular form arch position, can adopt hollow structure, but can not influence intensity for the position.
If hardening layer is thicker can't divide the time, can use in conjunction with impacting pump truck, perhaps carry out the macroplate dividing processing in advance, and then advance arch, so just realization is turned over and is split relatively easily.
Claims (3)
1. the backactor of a harden ground is characterized in that adopting that the ascending cross section in preposition front and back is that triangular form arch structure is formed pavement digger on the crawler type promotion machine.
2. according to claim 1, it is characterized in that arch structure can imitate twin wrest formula structure.
3. according to claim 1, it is characterized in that triangular form arch position employing hollow structure.
