Abstract
A nose with a lengthened pipe of a slurry-water balance pipe jacking machine comprises a nose, and is characterized in that a circle of connecting lugs is arranged on the inner wall of the end of the nose, one end of a lengthened pipe equal to the nose in diameter is a connection section, the diameter of the connection section is smaller than the pipe diameter the lengthened pipe, a circle of connecting lugs is also arranged at the end of the connection section, a seal groove is arranged on the outer side of the connection section, the connection end of the lengthened pipe is inserted into the nose, the lengthened pipe and the nose are connected through the connecting lugs, bolts and nuts, and a seal ring is arranged in the seal groove. When the nose with a lengthened pipe is used, the lengthened pipe is connected with the pipe jacking nose, so that the length of the nose is increased, balance stability of the whole nose in mucky clay can be improved greatly, and direction adjustment and corrective operation and control effects of the nose in the processing of jacking in a mucky clay layer o is enhanced wen soil covering of the large-caliber pipe jacking machine is shallow.
Description
Technical field
The utility model relates to a kind of mire water equilibrium tube machine head with extension pipe.
Background technique
In recent years, along with the introduction of external advanced pipe jacking equipment and the development success of home equipment, pipe jacking construction technique reaches its maturity, and also along with pressing for of accelerated development and environmental pollution improvement built in urbanization, a pipe construction technology is used more and more wider.Owing to aspect reasons such as production, transportation, structures, mud-water balance item pipe machine head length in design has narrow limitation, and head weight is very big, in the engineering of mud matter clay, the characteristics that the push pipe head is short and heavy cause easily plants head, causes and can't carry head, thereby influence engineering.
The model utility content
The purpose of this utility model just provides a kind of simple in structure, easy to operate, can avoid the mire water equilibrium tube machine head of the band extension pipe of front end dip generation.
The mire water equilibrium tube machine head of band extension pipe of the present utility model, comprise head, the inwall that is characterized in the head end is provided with a circle engaging lug, extension pipe one end isometrical with head is linkage section, and the diameter of linkage section is less than the extension pipe caliber, and the end of linkage section also is provided with a circle engaging lug, have seal groove on the outer side surface of linkage section, the linkage section of extension pipe inserts in the head, connects with bolt nut by both engaging lug, places seal ring simultaneously in seal groove.
When the mire water equilibrium tube machine head of band extension pipe of the present utility model uses, link to each other with the push pipe head by extension pipe, increased the length of head, can improve the stability of equilibrium of integral body in mud matter clay at head position greatly, strengthened simultaneously under the shallow earthing situation of heavy caliber pipe-jacking machine, the control effect is handled in the adjustment of jack-in process heading and correction in mud matter clay layer.
