Abstract
The invention relates to the field of civil engineering, in particular to a separate launching construction method of a shield tunneling machine in narrow space. First, second, third and fifth trolleys of the shield tunneling machine are bilaterally separated and separately fitted correspondingly to prefabricated empty trolleys, the trolleys are then lifted sequentially into a well for assembly, remaining auxiliary trolleys are placed on the ground near a launching end well, pipelines among the trolleys are connected, launching is started after the shield tunneling machine is finished, the upper half of a negative ring segment is removed after 40 rings of shield launching are finished, the trolleys are drawn to the launching end well by using a battery vehicle and are lifted to the surface for reassembly according to design drawings, the trolleys are lifted into the well in a sequence of first to seven, and assembly and debugging are then carried in at the bottom hole before launching is carried out again. By modifying the trolleys and re-sequencing the trolleys, at the premise of ensuring smooth launching of the shield tunneling machine, the modification quantity and connection length of various pipelines are reduced as far as possible. The shield tunneling machine is separately launched, a full-ring unearthing construction technique is used, and thus a construction period is greatly shortened.
Description
Technical field
The present invention relates to field of civil engineering, specifically relate to a kind of small space shield machine separate launching construction method.
Background technology
In the subway Line 1 work progress of Hefei, station, Pueraria lobota large shop is an island platform station, and adopt cut and cover tunneling, because first bus station structure clear span is narrow and small, (station side wall is to column clear span only 4.1m, shield machine station clear span 4.5m), vehicle frame entirety cannot pass through station smoothly.
Summary of the invention
For the technical problem existed in prior art, the object of wood invention is to provide a kind of small space shield machine separate launching construction method.
To achieve these goals, the technical solution adopted in the present invention is: a kind of small space shield machine separate launching construction method, it is characterized in that: by shield machine No. 1, No. 2, No. 3, No. 5 chassis left and right sides are taken apart, and correspondingly with the empty station car made in advance respectively to assemble, shield machine frame width is transform as 3.8m by 4.5m, hang in down-hole more in order to assemble, the auxiliary chassis of residue is positioned over ground near starting end head well, then the pipeline between each chassis is connected, shield machine starts after having debugged, complete after 40 rings (60m) until shield launching, remove the first half and bear endless tube sheet, adopt battery truck by chassis traction to starting end head well, winch to ground to re-assembly by plan again, and lift into well according to the order of 1 ~ No. 7 chassis, assemble in down-hole again, debugging, again start.
Small space shield machine separate launching construction method of the present invention, its beneficial effect shows:
1, by transformation chassis, again organize into groups chassis order, ensureing, under the prerequisite that shield machine can start smoothly, to decrease each road pipeline modification quantity and connecting length as much as possible.
2, adopt shield machine separate launching, the construction technology that the domain is unearthed, shorten construction period greatly.
Accompanying drawing explanation
Fig. 1 is the workflow diagram of small space shield machine separate launching construction method of the present invention.
Detailed description of the invention
For further describing small space shield machine separate launching construction method of the present invention, below in conjunction with accompanying drawing, it is described further.
Refer to shown in Fig. 1, a kind of small space shield machine separate launching construction method, by shield machine No. 1, No. 2, No. 3, No. 5 chassis left and right sides are taken apart, and correspondingly with the empty station car made in advance respectively to assemble, shield machine frame width is transform as 3.8m by 4.5m, hang in down-hole more in order to assemble, the auxiliary chassis of residue is positioned over ground near starting end head well, then the pipeline between each chassis is connected, shield machine starts after having debugged, complete after 40 rings (60m) until shield launching, remove the first half and bear endless tube sheet, adopt battery truck by chassis traction to starting end head well, winch to ground to re-assembly by plan again, and lift into well according to the order of 1 ~ No. 7 chassis, assemble in down-hole again, debugging, again start.
The Third Construction Co., Ltd. is in the subway Line 1 work progress of Hefei, technician is by on-the-spot construction technology of being unearthed by shield machine separate launching, the domain under the narrow and small working space of introduction employing, preferably resolve because of the narrow and small problem of station structure clear span, and the operating mode of 4# shield machine separate launching is analyzed, draw the clear superiority of this kind of construction method in duration, economic dispatch: effectively improve construction speed, ensure that construction safety, save construction cost.Under this novel narrow and small working space, shield machine separate launching is marked in station, Pueraria lobota large shop-water Yangjiang way station (right line) shield launching work in November, 2014 for Hefei track traffic Line 15.
Above content is only to design example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
