Abstract
The invention relates to an anti-sidetracking device of a rectangular tunnel boring machine, in particular to an air-cushion-type anti-sidetracking device for construction with a rectangular tunnel boring machine. The device comprises a rectangular tunnel boring machine, and is characterized in that the rectangular tunnel boring machine is internally provided with an air compressor, the air compressor is connected with an air pack in series through a pipeline, the air pack is connected with air cushion inflation inlets distributed on the top and the bottom of the rectangular tunnel boring machine through a pipeline, the number of the air cushion inflation inlet on the two sides of the top and the bottom of the rectangular tunnel boring machine 1 are respectively one, and each air cushion inflation inlet is connected with the air pack through a one-way valve, a pressure control valve and an air pressure meter. The advantages of the invention are that the compressed air produced by the air compressor is conveyed to the air cushion inflation inlet on the top and the bottom of the rectangular tunnel boring machine under the control of the controller, so as to form an air cushion to control the sidetracking of the rectangular tunnel boring machine.
Description
Technical field
The present invention relates to the anti-side rotating device of a kind of rectangular tunnel boring machine, particularly a kind of anti-side rotating device of air-cushion type that is used for the rectangular tunnel boring machine construction.
Background technology
Along with the fast development of urban underground space exploitation, the Rectangular Tunnel circular tunnel of comparing because it has and improve the tunnel cross-section utilization rate, descend the advantage of aspects such as space resources, reduction construction costs frugally, and has obtained increasing use.But in the Rectangular Tunnel work progress;, axis inhomogeneous owing to soil property rectified a deviation, the reasons such as pressure fluctuation of top, back jack, and rectangular tunnel boring machine is prone to lateral deflection takes place, and causes the run-off the straight of Rectangular Tunnel bottom surface; With function of use and the application life after directly influencing Rectangular Tunnel and building up; Therefore, in the rectangular tunnel boring machine work progress, need rectify a deviation, deflection control has also just become one of technological emphasis and difficult point in the rectangular tunnel boring machine construction.
Summary of the invention
The objective of the invention is to solve easy existing the problems referred to above of lateral deflection that take place of rectangular tunnel boring machine in the prior art, a kind of anti-side rotating device of air-cushion type that is used for the rectangular tunnel boring machine construction is provided.The present invention designs a kind of anti-side rotating device of air-cushion type that is used for the rectangular tunnel boring machine construction; Comprise rectangular tunnel boring machine; It is characterized in that: an air compressor is installed in rectangular tunnel boring machine; Air compressor is connected with bellows chamber by pipeline; Bellows chamber by pipeline be distributed in the rectangular tunnel boring machine end face and be connected with air cushion inflation inlet on the bottom surface, the air cushion inflation inlet respectively has 1 at the end face of rectangular tunnel boring machine and the both sides of bottom surface, each air cushion inflation inlet is linked to each other with bellows chamber by one way valve, pressure-control valve and air gauge.It is characterized in that: bellows chamber is provided with safety valve.It is characterized in that: two air cushion inflation inlets of two air cushion inflation inlets of end face and bottom surface are symmetrically distributed.Advantage of the present invention is the compressed air that utilizes air compressor to produce, and under the control of controller, is delivered to the air cushion inflation inlet of rectangular tunnel boring machine end face and bottom surface, forms air cushion, the lateral deflection of control rectangular tunnel boring machine.
Description of drawings
Accompanying drawing 1 is a texture edge cut-away view of the present invention.
Accompanying drawing 2 is the AA sectional drawing of Fig. 1 of the present invention.
The specific embodiment
Comprise rectangular tunnel boring machine among the figure; It is characterized in that: an air compressor 2 is installed in rectangular tunnel boring machine 1; Air compressor 2 is connected with bellows chamber 4 by pipeline 3; Bellows chamber 4 by pipeline 3 be distributed in the rectangular tunnel boring machine end face and be connected with air cushion inflation inlet 6 on the bottom surface, air cushion inflation inlet 6 respectively has 1 at the end face of rectangular tunnel boring machine 1 and the both sides of bottom surface, each air cushion inflation inlet 6 is linked to each other with bellows chamber 4 by one way valve 7, pressure-control valve 8 and air gauge 9.It is characterized in that: bellows chamber 4 is provided with safety valve 5.It is characterized in that: two air cushion inflation inlets 6 of end face and two air cushion inflation inlets of bottom surface 6 are symmetrically distributed.
In rectangular tunnel boring machine 1 construction, start stable gas pressure that air compressor 2 makes bellows chamber 4 in the certain pressure value, when lateral deflection takes place rectangular tunnel boring machine 1; Bellows chamber 4 is delivered to the air cushion inflation inlet 6 of rectangular tunnel boring machine 1 end face and bottom surface with high pressure draught, according to the degree of deflection of rectangular tunnel boring machine, under the control of air cushion inflation inlet 6 pressure-control valves 8; The high pressure draught of certain pressure is sprayed from air cushion inflation inlet 6; Form air cushion, rectangular tunnel boring machine is produced a power, control the ejection of the high pressure draught of air cushion inflation inlet 6 respectively; Also can form a couple, thus the lateral deflection of control rectangular tunnel boring machine 1.
