Abstract
The utility model relates to a machine head of a muddy water balanced pipe jacking machine with a lengthened pipe, which comprises the machine head and is characterized in that a ring of connecting lugs are arranged on the inner wall at the end part of the machine head, one end of the lengthened pipe with the same diameter of the machine head is a connecting section, the diameter of the connecting section is smaller than the diameter of the lengthened pipe, a ring of connecting lugs are also arranged at the end part of the connecting section, a seal groove is arranged on the outer side surface of the connecting section, the connecting section of the lengthened pipe is inserted in the machine head, the connection is carried out by using bolts and nuts through the connecting lugs of the two, and a seal ring is simultaneously arranged in the seal groove. When the machine head of the muddy water balanced pipe jacking machine with the lengthened pipe is used, the length of the machine head is increased by connecting the lengthened pipe and the machine head of the pipe jacking machine, thereby greatly improving the stability of the balance of the whole machine head part in slurry clay and simultaneously strengthening the effects of adjustment and deviation correction manipulation control of the direction of the machine head during the jacking process in the slurry clay layer under the situation of shallow covered earth of the large caliber pipe jacking machine.
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, pipe jacking construction technique is used more and more wider.Owing to aspect reasons such as production, transportation, structures, mire water equilibrium tube 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.
Summary of the invention
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.
Description of drawings
Fig. 1 is the utility model structural representation.
