Abstract
The invention relates to an assembled tie for shield construction and a construction method thereof, belonging to the technical field of tie pavement in shield construction. The assembled tie is formed by splicing two trolley ties and a slag car tie; the baseplate of the assembled tie is cambered; and the existing joist steel ties are replaced by a cambered right-angled triangle plate and a trapezoidal plate. The assembled tie has the advantage of light weight and the like, is easy to stack, and can protect shielded duct pieces. In the construction process, the trolley ties at the back of the trolleys, which are not used any more, are continuously disassembled, thus improving the use ratio of construction members and effectively reducing the construction cost. The assembled tie and the construction method thereof can be widely applied to installing mechanical ties in the process of the shield construction.
Description
Technical field
The present invention relates to sleeper and job practices thereof in a kind of shield-tunneling construction.
Background technology
Shield machine is as current state-of-the-art tunnel piercing ultra-large type special equipment, be realize driving, be unearthed, high-tech construction equipment that cavitation is once excavated in supporting etc., be widely used in construction of tunnel such as urban track traffic, railway, highway, municipal administration, water power.
The level transportation is an important step in the shield-tunneling construction process in the tunnel.At present, transport sleeper in the metro shield constructing tunnel in the hole and be mostly H shaped steel, i iron processing and fabricating, spacing is between 1～1.2m, along with the propelling of shield structure is constantly laid, until tunnel holing through.This kind sleeper mode has the steel material of expending big, Heavy Weight, and shortcomings such as difficulty are deposited in carrying inconvenience.
With the immediate prior art of the present invention is to have disclosed the laying method that transports in the tunnel in a kind of shield-tunneling construction with sleeper in the patent of invention " a kind of shield gantry car and electric locomotive are set up the method for sleeper separately " (patent No. 200610024101.8); Be characterized in: the little sleeper that big sleeper that the follow-up chassis of shield structure need be used and flat bed transport vehicle need be used, set up separately respectively and lay; Along with shield-tunneling construction advances, constantly lay the little sleeper that supplies flat bed transport vehicle to use; Remove the left and right paired wheel sleeper of the follow-up chassis of shield structure that supported, place mat is made the follow-up chassis of new shield structure in the shield-tunneling construction direction of advance and is supported.The sleeper of the left and right wheel of supporting chassis is two i iron behind this shield structure, constitutes a unequal-sided right angle triangle, and minor face vertically withstands the tunnel round bottom, and the tunnel side is shelved on long limit.Say that from efficiency of construction this i iron setting is not easy to carrying in the construction; From the finished product protection aspects, this set easily with the shield duct piece damaged surfaces, makes shield duct piece truncation arrisdefect when serious under supporting chassis, level transportation battery truck marshalling weight behind the shield structure; Relatively, the main material of small-sized sleeper is the 8# channel-section steel from the efficiency of construction aspect, owing to be straight, easy deformation under level transportation battery truck marshalling weight causes level transportation battery truck to organize into groups rail, influences construction speed.
Summary of the invention
The purpose of this invention is to provide a kind of shield-tunneling construction with assembling sleeper and job practices thereof, solve existing sleeper inconvenience carrying, damage shield duct piece easily by pressure, the technical problem that efficiency of construction is low.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of shield-tunneling construction is used the assembling sleeper; Be spliced by slag car sleeper and chassis sleeper, said slag car sleeper is formed by two trapezoidal plates, a curved plate B, two top board B and two junction plate B Combination Welding, and the hypotenuse of said trapezoidal plate is an arc; Its symmetry is vertically welded in the two ends central authorities of curved plate B; Said top board B is vertically welded in the end face of trapezoidal plate, has the fixedly bolt hole of the pressing plate connection of slag car rail on it, and said junction plate B is vertically welded on the minor face of trapezoidal plate;
Said chassis sleeper is welded by two right angle triangles, two curved plate A, two top board A and two junction plate A; The hypotenuse of said right angle triangle is an arc; It is vertically welded in the central authorities of curved plate A; Said top board A is vertically welded in the end face of right angle triangle, has the fixedly bolt hole of chassis rail pressing plate on it, and said junction plate A is vertically welded on the right angle minor face of right angle triangle;
Said chassis sleeper is two, splices respectively at the two ends of slag car sleeper, and the junction plate A on the chassis sleeper is connected through bolt with junction plate B on the slag car sleeper.
Said curved plate A and the wide uniform thickness of curved plate, its width is 120mm, and its thickness is 8mm.
The bolt number of a said end is at least two.
Described shield-tunneling construction is with the job practices of assembling sleeper, and construction sequence is following:
Adjacent two assembly units are good in the said step 4 slag car sleeper and the clear distance between the chassis sleeper are 1～1.2m.
Compared with prior art the present invention has following characteristics and beneficial effect:
The present invention is processed into arc with base plate, is close to shield duct piece bottom, can reduce that the slag car falls the rail phenomenon in the shield-tunneling construction, improves efficiency of construction.
This method adopts the assembling sleeper and replaces H shaped steel, i iron to do the construction sleeper with the circular arc steel work, has reduced the stacking place, can reuse, and has reduced construction cost.Because construction weight is lighter, be convenient to carrying in the construction, thereby improved efficiency of construction, shortened the duration.
Pass through in the work progress of the present invention the chassis sleeper of chassis process is removed, recycle, thus the turnover rate of raising constructional materials reduces construction cost.
The present invention can be widely used in sleeper and the job practices thereof in the shield-tunneling construction.
