Description

A kind of balancing earth-pressure shielding machine soil storehouse mud cake detection device
Technical field
The invention belongs to subway tunnel shield technical field;Particularly relate to a kind of balancing earth-pressure shielding machine soil storehouse mud cake detection device.
Background technology
Along with increasing and traffic above-ground facility the load of China's big city population increases the weight of day by day, the exploitation of the underground space have just become vast city planning design personnel's focus of attention, shield method is also widely adopted in city track traffic engineering, but shield machine is at silty clay, when the stratum such as mud stone and argillaceous siltstoue uses, tunneling process usually can run into this difficult problem of cutterhead mud lining, mud cake is the tiny sand grains that shield cutter cuts, semi-consolidated and the blocks of consolidation shape that chip reassembles in soil storehouse, the existence of mud cake has not only increased the weight of the load of cutter head of shield machine and cutter, and usually make boring parameter that sudden change occurs, efficiency of construction is made to be substantially reduced, have influence on the safety of driving to a certain extent, the durability of equipment and the reasonability of construction organization.
Summary of the invention
The goal of the invention of the present invention:
Primarily to solve shield machine to produce cutterhead this technical problem of mud cake capstan winch in tunneling process, it is provided that a kind of driving security performance is high, the shield machine mud cake detection device that equipment persistency is strong.
The technical scheme is that
Provide a kind of balancing earth-pressure shielding machine soil storehouse mud cake detection device, including balance shield machine central partition plate, central partition plate is provided with mud cake sense channel, it is provided with steel pipe in mud cake sense channel, center-pole it is plugged with in steel pipe, the center-pole both ends of steel duct are provided with sealing ring, the rear end of steel pipe is provided with adapter, adapter is socketed with manual ball valve, the rear end of manual ball valve is provided with adpting flange, center-pole is connected fixing by connecting bolt by adpting flange, steel pipe is connected with the central partition plate of shield machine by welding, and on steel pipe, it is provided with support ring, described sealing ring uses O RunddichtringO, the mud cake sense channel arranged on central partition plate is symmetrical two.
The invention has the beneficial effects as follows:
The detection of mud cake in soil storehouse is greatly facilitated, it is also possible to utilize mud cake detection hole that the stratum in cutterhead front is carried out advance reinforcement and aid in treatment boulder, improve drivage efficiency and the production safety performance of shield machine during shield machine driving shield.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation of the mud cake detection device of the present invention.
In figure;1 is steel pipe;Bar centered by 2;3 is adapter;4 is manual ball valve;5 is adpting flange;6 is sealing ring;7 is connecting bolt;8 is support ring;Dividing plate centered by 9;10 is mud cake sense channel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.
nullAs shown in Fig. 1~2,Provide a kind of balancing earth-pressure shielding machine soil storehouse mud cake detection device,Including balance shield machine central partition plate 9,Central partition plate 9 is provided with mud cake sense channel 10,Steel pipe 1 it is provided with in mud cake sense channel 10,Center-pole 2 it is plugged with in steel pipe 1,Center-pole 2 both ends of steel duct are provided with sealing ring 6,The rear end of steel pipe is provided with adapter 3,Adapter 3 is socketed with manual ball valve 4,The rear end of manual ball valve 4 is provided with adpting flange 5,Center-pole 2 is connected fixing by connecting bolt 7 by adpting flange 5,Steel pipe 1 is connected with the central partition plate 9 of shield machine by welding,And on steel pipe, it is provided with support ring 8,Described sealing ring uses O RunddichtringO,The mud cake sense channel arranged on central partition plate is symmetrical two,The present invention is simple and convenient,During concrete shield uses,After when shield machine advance one section,Unscrew connecting bolt,Center-pole is extracted backward,Because being provided with O RunddichtringO on center-pole,The generation of retention of excessive fluid can be effectively prevented at water-enriched layer,When center-pole extracts distance out to manual ball valve position,Manual ball valve is closed,After confirming without gushing,Manual ball valve is opened,Drill rod is squeezed in steel tube pathway,Whether detection shield machine has the generation of mud cake during shield driving,If there being the mud cake of excess,Can be by processing toward measures such as soil storehouse spray water under high pressures,Device is detected by this mud cake,Can effectively improve shield machine production efficiency during shield,Contribute to unit in charge of construction and find the generation of mud cake timely,And use effective safety measure,Protect the safety in production of shield machine simultaneously,It is especially suitable for promoting.
