The drilling bit is internally provided with a sensor and a display screen. The drilling bit has a trapezoidal cross section. The device provided by the utility model ensures construction precision of the long and large pipe shed which is constructed according to a one-time non-excavation pipe paving technique. Supporting effect of the pipe shed can be ensured without introducing structure range. A simple and practical pipe shed construction error-correcting adjusting system is formed. The device provided by the utility model has the functions of: greatly improving construction efficiency, ensuring advanced supporting effect in subway excavation, improving construction quality of advanced supporting pipe shed, and simultaneously reducing risk in excavation construction.
Description
Technical field
The utility model relates to underground structrue engineering technical field, relates in particular to the grow up device of pipe roof construction precision of a kind of raising.
Background technology
For the subway station that adopts the construction of supporting arch hidden digging top-down method, in construction, inevitably disturbed strata causes stratum deformation, and excessive stratum deformation can cause adverse effect to safety and the construction safety of surrounding environment (existing construction of structures, pipeline etc.).Therefore controlling the stratum settlement that shallow burial hidden digging construction causes plays a part very important to the success or failure of engineering.For the subway station of shallow burial hidden digging construction, the measure of controlling stratum deformation mainly contains: improvement formation condition, Optimizing construction engineering method, takes leading reinforcement measure etc.Research shows, ground settlement amount has 30% left and right to occur before Tunnel generation effect.Pipe canopy, as advance support householder method important in constructing tunnel, has positive effect in several respects such as anti-collapse, obstruct sedimentation, even stratum settlement, raising coffer mechanics parameters.
Meanwhile, because pipe roof construction has disguise highly, its work progress cannot be observed, and is also difficult for inspecting for acceptance after pore-forming, in different stratum constructions, has different construction technology control standards.Although this technique is just day by day perfect at present, often because traditional handicraft also can exist defect, causes shrinkage cavity, embrace to bore, disconnected pipe, invade the quality problems such as construction profile and also happen occasionally.In construction, the most common pipe roof construction quality problems are still managed canopy to set angle improper, make to manage that canopy is invaded tunneling excavation range of structures or angle deviating design attitude does not exist the risk of caving in compared with having greatly the effect of advance support.Therefore, analyze the scientific and reasonable technology controlling and process means of summing up, innovation improves technology measure, to guarantee that supporting arch hidden digging top-down method construction safety seems very important.
Utility model content
The purpose of this utility model is to provide a kind of raising device of pipe roof construction precision of growing up.
The technical solution of the utility model is as follows:
Raising is grown up and is managed the device of canopy precision: comprise drilling rod and a drill bit, drilling rod is connected by a reducer union with drill bit, is provided with sensor and display screen in drill bit, and drill bit cross section is trapezoid cross section.
Further, sensor comprises light-emitting device and probe;
Further, sensor is connected with holding wire with drilling rod.
Its technical essential is to adopt new trapezoid cross section pipe canopy drill bit to substitute traditional tapered cross-section pipe canopy drill bit, the monitoring equipment of installing according to drill bit internal, can monitor the angle of the offset design position of drill bit, the difference of drill bit and soil body contact area while then utilizing the direct jacking in trapezoid cross section, be subject to one perpendicular to the power on inclined-plane, thereby make drill bit change the adjustment that its drilling direction can be realized drilling direction angle.
The key point of technique is to improve grow up Real-Time Monitoring that the device of pipe roof construction precision forms and the integral framework of adjustment, this device not only has enough intensity, rigidity and stability, and form of structure simplicity of design, the feature that the difference of the form of structure of use device itself realizes unbalance stress is managed correction and the adjustment of canopy direction and angle.Main design innovation be in drill bit, install can monitor the signalling arrangement of drill bit direction and angle in drilling process, by improving drill bit structure form, realize the angle and direction that real-time adjustment drill bit creeps into.This control valve canopy sets the new equipment of precision, its form of structure simplicity of design, and stress is clear, can fast and effeciently manage the correction that canopy sets angle and direction according to monitoring situation, thereby reaches safe, fast, efficient tunneling construction requirement.
The beneficial effects of the utility model are: the raising of the present utility model features such as the drill bit structure form that the device of pipe canopy precision forms is simple, work progress rectifying effect is obvious of growing up, effectively hold the shortcoming that has overcome conventional tube canopy drill bit, for raising, grow up that the construction of the disposable no-dig laying pipelines technique of pipe canopy sets precision, the pipe roof construction quality of guaranteeing to grow up, guarantee that a tunneling reverse construction plays safely positive role.Facts have proved, the successful implementation of this " a kind of raising is grown up and managed the device of canopy precision ", not only simplicity of design, construction safety, reliable, and than traditional pipe canopy drill bit form, duration can shorten more than 15%, cost savings are more than 10%, and remarkable benefit, has good using value and dissemination.
Accompanying drawing explanation
Fig. 1 is conventional tube canopy drill bit design schematic diagram;
Fig. 2 is drill bit schematic diagram of the present utility model.
Description of reference numerals: 1-display screen; 2-drilling rod; 3-sensor; 4-tapered cross-section drill bit; 5-trapezoid cross section drill bit; 6-bracing frame; 7-holding wire; 8-reducer union.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The grow up device of pipe canopy precision of raising: by changing conventional drill (seeing Fig. 1) conical interface form, redesign the drill bit form at a kind of trapezoidal interface (seeing Fig. 2), utilize front end signal monitor real-time display frame to pipe canopy drill bit direction and adjust more greatly.Special sensor is housed in drill bit, and sensor is directly by 15V direct current supply.Display screen shows the inclination angle (level angle) of drill bit, towards angle (direction of guide strip: guide strip is 12 points upward, as clock face).If set angle on the lower side, drill bit can be transferred to 12 points, upward, directly jacking, now because guide strip bottom board inclined plane area is large for guide strip.Be subject to the power making progress, bit course will move upward.In like manner 6 corrections, can make bit course down, 9 points, 3 are to be respectively left and right correction direction.If angle is suitable, rig is rotary drilling at the uniform velocity, and now drilling rod track is generally straight by designing requirement, thereby reaches the requirement that improves pipe roof construction precision.
