Abstract
The invention discloses a method for modifying a shield driving system adapting to 22.5-degree duct pieces to adapt to 36-degree duct pieces. An original oil cylinder arrangement of a propulsion oil cylinders adopting evenly distributed 32 oil cylinders and adapting to 22.5-degree duct pieces is divided into four quadrants according to two axes, first, second, third and fourth supporting shoes in the first quadrant of the propulsion oil cylinder are modified to form five sets of new supporting shoes, the modification of the symmetrical positions of the other three quadrants is the same with the first quadrant, and ten adjustment positions in the circumferential direction of 360 degrees are each provided with a set of oil cylinder corresponding to the occurrence position of a top sealing block of a 36-degree duct piece. The method solves the problem that a shield adapting to the 22.5-degree duct pieces can not adapt to the 36-degree duct pieces, the modification time is shortened, the waiting period when the shield equipment stops in the project continuing interval is shortened, and the equipment adaptability is enhanced.
Description
Technical field
The present invention relates to tunnel piercing technical field, specifically relate to a kind of method adapting to 22.5 ° of section of jurisdiction shield propelling system transformations and extremely adapt to 36 ° of sections of jurisdiction.
Background technology
During subway tunnel shield method is constructed at home at present, the preset section of jurisdiction longitudinal bolt calibration that the tunnel of same diameter adopts has two kinds of specifications, that wherein Guangzhou, Shenzhen, Xi'an, Nanchang, Chengdu city underground adopt is external diameter 6000mm, internal diameter 5400mm, longitudinal bolt calibration is the prefabricated pipe section of 36 °; That Beijing, Zhengzhou, Wuhan, Shenyang urban subway adopt is external diameter 6000mm, and internal diameter 5400mm, longitudinal bolt calibration is the prefabricated pipe section of 22.5 °.These two kinds of every closed-loops in section of jurisdiction form by 6 pieces of sections of jurisdiction, and in the order of 6 pieces of pipe sheet assembling Cheng Huan, the section of jurisdiction at two finally assembled end band oblique angles becomes the block that binds, and needs propelling cylinder symmetry to push guarantee pipe sheet assembling quality.But section of jurisdiction ring needs constantly to adjust relative to the attitude of Tunnel Design center line the circumferential position of block in the ring of section of jurisdiction that bind according to shield structure center line in assembled process, the adjustment of circumferential position must follow the integral multiple principle of longitudinal bolt calibration, ensure arranging in the shield structure tens of propelling cylinders manufactured, often adjustment bind any circumferential position of block time all have the oil cylinder correspondence block symmetry that binds to push.The section of jurisdiction of present 22.5 ° assembled, the propelling cylinder of design is arranged only can for 22.5 ° of calibration sections of jurisdiction, only can be applicable to the assembled of 22.5 ° of sections of jurisdiction, the assembled of 36 ° of sections of jurisdiction can not be used for, limit Suporting structure only to use at specific urban subway tunnel, mutually can not adjust use in all cities, cause the waste of social resources.CN201972712, application number 201020509595.0, name is called that being suitable for the shield driving oil cylinder installed two kinds of calibration sections of jurisdiction arranges, this utility model adopts 24 oil cylinders to arrange as the quantity of shield driving oil cylinder, only just can meet the assembled of 22.5 ° and 36 ° sections of jurisdiction when manufacturing and designing, and the shield propelling system transformation being applicable to 22.5 ° of sections of jurisdiction that can not be used for having manufactured is to adapting to 36 ° of sections of jurisdiction.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and be applicable to 22.5 ° of section of jurisdiction shield propelling system transformations to the method adapting to 36 ° of sections of jurisdiction, solve the problem that the shield structure being applicable to 22.5 ° of sections of jurisdiction can not be applicable to 36 ° of pipe sheet assemblings.
In order to achieve the above object, technical scheme of the present invention is:
Arranged by the oil cylinder of the propelling cylinder of equally distributed for former employing 32 oil cylinders adaptation 22.5 ° of sections of jurisdiction and be divided into four quadrants by diaxon, comprise first quartile, the second quadrant, third quadrant, fourth quadrant, the transformation of first quartile comprises the following steps:
Step one: welding on the former No. 1 support boots of propelling cylinder is extended support boots, forms new No. 1 support boots, and install new No. 1 boots plate on new No. 1 support boots, enable propelling support boots and meet block 18 ° of positions assembled directly over departing from of binding;
Step 2: former No. 2, No. 3 of propelling cylinder support boots are divided into two, be respectively 2A and support boots and 2B support boots, 3A support boots and 3B support boots, 2B is supportted boots and 3A to support boots and be combined into new No. 3 support boots, and on new No. 3 support boots, new No. 3 boots plates are installed, enable propelling support boots and meet block 54 ° of positions assembled directly over departing from of binding, 2A is supportted boots and 3B to support boots and be modified as new No. 2 support boots and new No. 4 support boots respectively, and on new No. 2 support boots and new No. 4 support boots, new No. 2 boots plates and new No. 4 boots plates are installed respectively;
Step 3: former No. 4 support boots are not changed, become new No. 5 support boots, enable propelling support boots and meet block 90 ° of positions assembled directly over departing from of binding, the transformation of other three quadrant symmetrical positions is identical with first quartile, now, in circumference 360 ° 10 adjustment positions, all have a group oil cylinder to correspond to 36 ° of sections of jurisdiction to bind the position that block occurs.
Positive beneficial effect of the present invention:
1, solve the problem that the shield structure being applicable to 22.5 ° of sections of jurisdiction can not be applicable to 36 ° of pipe sheet assemblings, shorten the transformation time.
2, the cycle because of engineering continued access Suporting structure interval stopping wait being shortened.
3, the total quantity of domestic Suporting structure is reduced, cost-saving.
