Description
Technical field
The present invention relates to a kind of socket shield machine construction method, is the technical field of construction that belongs to a kind of non-excavation laying underground utilities.The bore that it is suitable for, generally should be meant the people can in pipe, carry out construction operation in, the laying of large-scale underground utilities.
Background technology
At present, in this, the job practices of large-scale pipeline non-excavation laying underground utilities has two kinds: a kind of jacking construction method of crying, the another kind of shield construction method of crying.
The jacking construction method is a kind of job practices of non-excavation laying underground utilities, and its equipment needed thereby is made of seven major parts shown in Figure 1 substantially: 1---received well, 2---push-bench, the follow-up pipe of 3---, 4---active well, 5---foundation ditch guide rail, 6---pressure-bearing steel loop, 7---jacking oil cylinder.Concrete method is: during construction, respectively constructing one in the pipe ends that will lay earlier works also and a received well, in active well, put into foundation ditch guide rail, jacking oil cylinder, push-bench and follow-up pipe, pressure-bearing steel loop etc. again, then, cut the earth by push-bench, with the jacking oil cylinder push-bench and follow-up pipe one joint one is saved land and to push up received well from active well, take out in received well up to push-bench, the laying work of whole piece pipeline is also accused and is finished.The top power of jacking construction method is along with the growth of jacking length increases, and therefore, it requires very high to the compressive strength of tubing.The compressive strength of tubing has restricted the jacking length of jacking construction method.If increase the continuous ejection device that jacking length just must be set up relay well, the whole piece pipeline is divided into plurality of sections pushes up.More than the relay well one, troublesome poeration, move speed are also slow.It is also uneconomical with the jacking construction method at the above pipeline of 3500mm to lay bore in addition.Adopt the shield construction method so generally lay the pipeline of the above bore of 3500mm more.
The shield construction method is the job practices of the underground large-scale pipeline of a kind of non-excavation laying.It is mainly by five most of compositions shown in Figure 2: the 1---received well, and the 8---shield machine, 9---advances oil cylinder, 10--section of jurisdiction, 4---active well.Shield construction method concrete grammar is described below: during construction, earlier respectively construct an active well and a received well in the pipe ends that will lay, in active well, put into shield machine again, advance the oil cylinder retraction with advancing oil cylinder that shield machine is pushed ahead certain distance with relief then, in retraction is reserved next space, a piece pipe sheet assembling is become an annular tube coupling with manipulator.Ring by ring ground assembly unit is forward later on taken out in received well up to shield machine, and the laying work of whole piece pipeline is also accused and finished.The section of jurisdiction is exactly that wherein each part is exactly a section of jurisdiction each endless tube joint break into portions.In order to make the Stability Analysis of Structures in tunnel, all can make certain angle that staggers mutually between two adjacent sections of jurisdiction usually, all connect between each piece section of jurisdiction, shown in Fig. 2 below with bolt or pin.Common shield construction method is section of jurisdiction shield construction method in fact, and the whole piece tunnel is become by a piece pipe sheet assembling.When adopting shield construction, its seam that the section of jurisdiction is many is also many, must handle each bar seam well, does not allow its seepage, is not a nothing the matter.And segment assembly is very time-consuming.Make its structural instability easily after having endless tube joint to be divided into some sections of jurisdiction again.
Summary of the invention
The objective of the invention is provides a kind of new underground pipeline laying construction method, i.e. socket shield machine construction method in order to overcome the shortcoming in the existing non-excavation laying underground pipeline construction method.
Technical scheme of the present invention is: a kind of socket shield machine construction method is characterized in that method step is:
1. on-the-spot have a plurality of with need corresponding its section of tubing size to have major axis, minor axis and on an end face, be equipped with the whole tube coupling of joint sealing circle;
2. respectively construct an active well and a received well in the pipe ends that will lay, in active well, put into shield machine, and by advancing oil cylinder that shield machine is pushed ahead;
3. arrive when pipe joint joint position can be installed when shield machine is pushed out active well, front end is with the first segment tube coupling of steel collar, be installed to place, active well hole, finish the installation of first segment tube coupling;
4. handle the sealing between first segment tube coupling and the active well hole, the space, hole is blocked with quick hardening cement;
5. continue to advance shield machine, in second pipe joint when joint, can be installed with crane second pipe joint be saved and hang down when being advanced to, laterally be transported to after the shield tail housing, turn 90 degrees by first second pipe joint joint is revolved around the Z axle of manipulator, again it is revolved around X-axis and turn 90 degrees, and by cushion block the integral ring-shaped tube coupling bed hedgehopping of this grade to desired height, lay by tube coupling that oil cylinder saves second pipe joint and the first segment tube coupling links up;
6. continue to advance shield machine, in three-joint pipe when joint, can be installed with crane three-joint pipe be saved and hang down when being advanced to, rotate the three-joint pipe joint by the 5th one step process, and by cushion block this pipe joint joint bed hedgehopping to desired height, lay that oil cylinder saves three-joint pipe and second pipe joint saves and links up by tube coupling;
7. repeat the 6th one step process the 4th pipe joint joint and three-joint pipe joint are connected, the 5th pipe joint joint and the 4th pipe joint joint connect, distance tube coupling transport with the tube coupling travelling bogie, pursue successively and save connection, until final section, be open to traffic, laying is finished.
The invention has the beneficial effects as follows:
The present invention compares with common shield-tunneling construction, and following advantage is arranged:
1. joint is to use whole tube coupling without pipe sheet assembling, has overcome the shortcoming of the seam seepage between the segment joint, saves many annexes and auxiliary material, has strengthened structural stability, and installation rate is accelerated.
2. the present invention has cancelled the secondary inner lining process in the common shield-tunneling construction, has reduced the construction section of pipeline, has shortened construction period widely, reduces construction cost.
3. joint sealing performance of the present invention is good, to adapt to the soil property scope wide.
