Technical Field

The invention relates to equipment for pushing construction of a round pipe culvert, and belongs to the technical field of building construction.

Background

The round pipe culvert pushing construction needs to arrange a reaction wall or a reaction support behind the pushing device to provide jacking force, and the reaction support is difficult to arrange at a soft soil foundation or a culvert opening with poor soil texture, and is often difficult to provide firm jacking reaction.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides equipment for pushing construction of a round culvert, which has the advantages of simple structure, convenience in installation and low cost, so as to overcome the defects in the prior art.

The technical scheme of the invention is realized as follows: the utility model provides an equipment for round pipe culvert pushes away construction, includes the guide rail and sets up the base on the guide rail, base and guide rail sliding fit, fixed mounting has support and gear motor respectively on the base, rotates on the support and installs driven gear, fixed mounting has the driving gear on gear motor's main shaft, and driving gear and driven gear intermeshing, sets up interface arrangement on driven gear's terminal surface, driven gear passes through interface arrangement and well union coupling, the other end of well pipe is connected with the head-tube through interface arrangement equally, is provided with the screw thread on the outer wall of well pipe and head-tube, is provided with the blade at the front end of head-tube.

Furthermore, the interface device is composed of two groups of rectangular teeth which are matched with each other, and the rectangular teeth and the driven gear, the middle pipe or the front pipe are of an integrated structure.

Furthermore, the rectangular teeth are provided with grouting holes.

Furthermore, the middle pipe is provided with one or more than one.

Due to the adoption of the technical scheme, the invention has the advantages that: the middle pipe and the front pipe are driven to rotate by the motor, and the middle pipe and the front pipe can automatically advance by the threads on the outer wall of the middle pipe and the front pipe, so that the requirement on the counter-force support is reduced or even eliminated. The pushing construction of the culvert can be realized under the condition that the foundation of the opening is poor, and the damage to the road surface is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention comprises the following steps: referring to fig. 1-3, an apparatus for pushing construction of a circular culvert comprises a guide rail 1 and a base 2 arranged on the guide rail 1, wherein the base 2 is in sliding fit with the guide rail 1, a support 3 and a reduction motor 4 are respectively and fixedly arranged on the base 2, a driven gear 6 is rotatably arranged on the support 3, a driving gear 5 is fixedly arranged on a main shaft of the reduction motor 4, the driving gear 5 is meshed with the driven gear 6, an interface device 7 is arranged on an end face of the driven gear 6, the driven gear 6 is connected with a middle pipe 8 through the interface device 7, the other end of the middle pipe 8 is also connected with a front pipe 9 through the interface device 7, threads are arranged on outer walls of the middle pipe 8 and the front pipe 9, and a cutting edge 10 is arranged at the front end of the front pipe 9. The interface device 7 is composed of two groups of rectangular teeth 12 which are matched with each other, and the rectangular teeth 12 and the driven gear 6, the middle pipe 8 or the front pipe 9 are of an integrated structure. The rectangular teeth 12 are provided with grouting holes 11. The number of the middle pipes 8 is one or more, and the specific number is determined according to the depth of the culvert.

During construction, lay guide rail 1 at the culvert mouth, and erect devices such as base 2 on guide rail 1, support 3 and gear motor 4, then be connected well pipe 8 and driven gear 6 on the support 3 through interface arrangement 7, connect fore-tube 9 on well pipe 8 through interface arrangement 7 again, then start gear motor 4, drive well pipe 8 and fore-tube 9 through gear motor 4 and rotate, and well pipe 8 and fore-tube 9 can rely on the screw thread on self outer wall to advance by oneself, thereby reduce or even cancel the requirement to the counter-force support. The pushing construction of the culvert can be realized under the condition that the foundation of the opening is poor, and the damage to the road surface is reduced.

And after all pipe joints are constructed, grouting is performed on a gap between the outer wall of the culvert pipe and the soil body through the grouting holes 11 reserved on the interface device 7 so as to reinforce the joint. The drilling direction of the pipe can be adjusted by means of earth excavation in the pipe.
