Description
Technical Field
The invention relates to the technical field of pipe jacking construction, in particular to a pipe jacking construction auxiliary facility.
Background
The existing sewage jacking pipe joint is generally a socket pipe and adopts a flexible joint. The front end surface and the rear end surface of the pipe joint are planes, the front end is a socket end, the rear end is a socket end, and a socket steel ring is preset outside the socket end. During construction, the socket end of the later section of pipe joint is inserted into the bellmouth steel ring of the previous section of pipe joint and is tightly attached to the end face of the bellmouth, and then jacking force is applied to the tail part of the newly inserted pipe joint to push the tunnel pipe joint to advance in the soil layer. The bellmouth steel ring plays a role in radial limiting, but when jacking force is not balanced or stratum is not uniform, the problem of slab staggering is easily caused between pipe joint joints, and the opening amount of the joints cannot be controlled.
When the pipe-jacking tunnel is constructed, turning of the curved tunnel and adjustment of tunnel axis construction errors are realized by completely depending on slow deflection of a cutter head of the pipe-jacking machine head, asymmetric cutting of end soil bodies and adoption of a multi-section hinged machine head. The rectification after the sinking of the machine head in a soft soil layer is realized by completely depending on the jacking force of the tail part and the deflection of the machine head of the push bench. When the construction is carried out in a weak stratum or the hinged pipe jacking machine head is adopted for pipe jacking construction, the joint bell mouth steel ring cannot form effective rigid connection between the longitudinal pipe joints, the tool pipe is easy to sink in the excavation process, so that the subsequent pipe joints sink continuously, the tunnel construction axis deviates from the design axis, the sink part is easy to accumulate water in the operation stage, the deviation rectification is difficult, the construction efficiency is low, and the effect is poor. In addition, the tunnel pipe joints only limit the freedom degree in the axial direction, and the radial and circumferential freedom degrees are not limited, so that a reliable anti-rotation device is not arranged between the pipe joints, the pipe joints and a machine head are easy to rotate in the construction process, and no effective correction measure is available.
Moreover, when the number of pipe joints is accumulated to a certain degree, the thrust of the push bench is difficult to be transmitted to the push pipe at the foremost end through the layer-by-layer pipe joints, which can cause insufficient thrust and difficult to continue the push pipe.
The Chinese patent publication number is: the invention patent of CN106246189A discloses a method for installing a pipe joint of a pipe-jacking tunnel, which comprises the steps of hoisting a first pipe joint in a jacking construction area; the first pipe joint comprises a female end and at least one female end assembling hole which is inwards concavely arranged along the female end; providing at least one group of adjusting connecting components, and connecting the adjusting connecting components with the bearing end assembling holes in an assembling way; hoisting a second pipe joint in the jacking construction area; the second pipe joint comprises a socket end and at least one socket end assembling hole which is inwards concavely arranged along the socket end; adjusting the position of the female end assembling hole to be aligned with the male end assembling hole, and matching and splicing the female end and the male end; the adjusting and connecting assembly is simultaneously assembled and connected with the plug end assembling hole and locked and fixed with the first pipe joint and the second pipe joint, so that the rigid connection of the first pipe joint and the second pipe joint is realized, the structural strength is high, the connection is stable, the efficiency and the precision of installation and construction are improved, and the anti-seismic performance of the installed pipe-jacking pipe joint is good.
In the above patent, although the rigid connection between the first pipe joint and the second pipe joint is realized, the structural strength is high, and the connection is stable, but after the number of the pipe joints is accumulated to a certain degree, the problem of insufficient thrust still exists, so that it is inconvenient to provide additional thrust to help the pipe joint at the most front end to be screwed in.
Based on the above, we propose a pipe jacking construction auxiliary facility, and hopefully solve the defects in the prior art.
