Description
Technical Field
The utility model relates to an auxiliary tool for tunnel construction, in particular to a steel pipe connection auxiliary tool for section installation of a tunnel reinforcement pipe shed.
Background
In order to ensure the safety of tunnel excavation and tunnel entering construction, the greenhouse is widely applied. When the geological condition is worse, in order to improve the intensity of the pipe shed, a steel reinforcement cage is arranged in the steel pipe of the pipe shed. The current common construction method of the pipe shed adopts a down-the-hole drill to guide holes, and then uses tools such as an excavator or a loader to push the pipe shed steel pipes into the holes for installation in place; because the length of the steel pipe of the pipe shed and the steel reinforcement framework in the steel pipe is large, the rigidity is small, the installation and the positioning of the one-time integral pushing hole are difficult, and the sectional installation construction is required; when the pipe shed steel pipes and the steel bar frameworks are installed together in a segmented mode, the steel bar frameworks in the pipe shed steel pipes are required to be connected firstly, then the external pipe shed steel pipes are connected in a closing mode, the rigidity of the exposed steel bar frameworks before the pipe shed steel pipes are connected in a closing mode is smaller than that of the pipe shed steel pipes on the two sides, the exposed steel bar frameworks are easy to bend due to force application pushing at the tail portions of the pipe shed steel pipes, and therefore an auxiliary tool for connecting the pipe shed steel pipes after the connection of the steel bar frameworks is completed is required to be designed, and the connection straightness of the steel bar frameworks and the pipe shed steel pipes is guaranteed.
Disclosure of Invention
The utility model aims to overcome the problems of the prior art and provides an auxiliary tool for installing steel pipes in sections of a tunnel reinforcement pipe shed, which can prevent an exposed reinforcement cage from bending in the process of gathering the steel pipes of the pipe shed, ensure that the reinforcement cage and the steel pipes of the pipe shed are connected smoothly, and improve the connection quality and efficiency.
The utility model adopts the technical proposal for solving the technical problems in the prior art that:
the utility model relates to a steel pipe connection auxiliary tool for installing a tunnel reinforcement pipe shed section by section, which comprises two clamps which are arranged at intervals in front of and behind a coaxial line, wherein each clamp is of a hoop structure, the two clamps are respectively used for clamping the tail part of a steel pipe of a pipe shed of a front section and the front end of a steel pipe of a pipe shed of a back section, two rectangular frame structures are arranged at intervals up and down oppositely, each rectangular frame structure comprises two clamp beams which are arranged at intervals left and right oppositely, the two clamp beams are connected through two pull rods which are arranged in the front and back along the horizontal direction, and the pull rods are fixed with the clamp beams which are correspondingly connected through nuts; the upper and lower mounting lugs of the left clamp are respectively pressed against the inner walls of the upper and lower clamp cross beams on the left side in the two rectangular frame structures; the base bodies of the upper jack and the lower jack respectively press the inner wall arrangement of the upper clamp beam and the lower clamp beam on the right side in the two rectangular frame structures, the ejector rods of the upper jack and the lower jack are arranged along the horizontal direction and respectively jack up the upper mounting lug and the lower mounting lug of the clamp on the right side.
The utility model has the advantages and positive effects that: in the construction process of sectionally installing the steel reinforcement frameworks in the pipe shed steel pipes and drawing the pipe shed steel pipes together, the compression length of the steel reinforcement frameworks is shortened, the force application axis is kept consistent with the axes of the steel reinforcement frameworks and the pipe shed steel pipes, the exposed steel reinforcement frameworks are prevented from bending in the process of drawing the pipe shed steel pipes together, the connection smoothness of the steel reinforcement frameworks and the pipe shed steel pipes is ensured, and the connection quality and efficiency are improved.
