Description
Technical Field
The invention belongs to the technical field of tunnel construction, and particularly relates to an adjustable construction bench for a large-gradient tunnel.
Background
Currently, the current state of the art commonly used in the industry is as follows:
after the 21 st century, the human society has been coming to a high speed. With the increasing prominence of population, resources, environment, traffic and other problems, the development of underground space resources is quickened, so that the underground space resources become safe and comfortable living spaces of all people on the earth, and the underground space resources become the content of extensive attention and vigorous research of various countries.
Along with the continuous promotion of the urban process, subway construction is rapidly developing. In urban busy areas, traffic lanes and densely populated areas, more and more subway stations are constructed by adopting a subsurface excavation method in order not to destroy the existing traffic conditions and not to influence the daily life of residents around the engineering. In the tunnel entrance and exit construction in the construction of the subsurface excavation method, the construction of the entrance and exit tunnel generally has a larger excavation gradient.
When the construction of the tunnel with a large gradient entrance is to be dealt with, the general method is as follows: when the underground tunnel entrance is constructed, the inclination angle of the rack is reduced by means of slag filling on one side of the rack, and the inclination of the rack is reduced by continuously filling slag while the rack is driven. The method has complex procedure, large slag filling engineering quantity and poor control of the angle of the rack; the pad slag occupies longer time, and has certain interference to construction production, so that the work efficiency is reduced; and the pad sediment later stage needs in time to clear up, needs reuse slag discharging equipment, causes the waste of resource.
In summary, the problems of the prior art are:
during tunnel construction, the rack angle is not well controlled, and the mode of filling up the sediment has reduced work efficiency, causes the waste of resource.
Difficulty and meaning for solving the technical problems:
the heights of the support rods of the rack are fixed, the angle cannot be adjusted, the amount of engineering required by a slag filling mode is large, certain interference exists on construction production, the slag filling later period needs to be cleaned in time, and slag discharging equipment needs to be reused;
the invention is improved on the link of tunnel construction at the entrance and the exit in the face of increasingly widely applied tunnel shallow-buried underground excavation construction methods, and tools which are more efficient in construction are manufactured so as to meet the requirements of tunnel development.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the adjustable construction bench for the large-gradient tunnel, which increases the universality of the bench and improves the economic benefit and the working efficiency.
The adjustable construction bench for the large-gradient tunnel is provided with a movable bench, and the movable bench is connected with diagonal bracing I-steel through a hinge;
the two ends of the front and back screw thread sleeve are screwed into the front screw thread stud and the back screw thread stud respectively, the front screw thread stud is fixedly arranged on the movable bench through hinge connection, and the back screw thread stud is fixedly arranged on the diagonal bracing I-steel through hinge connection.
Further, the hinge is fixed on the movable rack through bolt connection, and the position of the hinge can be detached and moved at any time.
Further, the through hole is formed in the middle of the positive and negative thread sleeve, and steel bars or other tools can be inserted into the through hole, so that operators can conveniently rotate the positive and negative thread sleeve easily.
Further, the outer ends of the positive thread stud and the negative thread stud are respectively welded with a semicircular connecting plate, round holes are formed in the semicircular connecting plates, and the semicircular connecting plates are respectively connected with hinges on the movable rack and the diagonal bracing I-steel through the round holes.
In summary, the invention has the advantages and positive effects that:
compared with the prior art, the improved subsurface tunneling tool for optimizing the entrance tunnel excavation method increases the universality of the tunneling bench by improving the tunneling bench. The positive screw thread stud and the negative screw thread stud are respectively screwed into two ends of the positive screw thread sleeve and the negative screw thread sleeve, and when the positive screw thread stud and the negative screw thread stud are respectively fixed on the rack and the diagonal bracing, the purpose of controlling the angle of the diagonal bracing I-steel is achieved by rotating the positive screw thread sleeve and the negative screw thread sleeve. A through hole is formed in the middle of the front and back thread sleeve, a steel bar or other tools are inserted into the through hole, and an operator can easily rotate the front and back thread sleeve. Through the improved tunneling tool, the tedious process of repeatedly laying the muck on the bench is avoided when the entrance tunnel is excavated, the improvement cost is low, the operation is simple and convenient, the field operation environment can be improved, and the construction speed is increased on the premise of ensuring the operation safety.
