Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shaft auxiliary sinking and posture adjustment, especially a mechanical tunneling type shaft auxiliary sinking and posture control system. BACKGROUND

[0002] With the continuous development of urbanization, ground space resources are increasingly scarce, and how to efficiently and reasonably develop and utilize underground space is increasingly valued. In recent years, mechanical tunneling type sinking well construction technology has begun to be applied to shaft engineering because of its advantages such as fast construction speed, small construction land occupation, wide stratum adaptability, and small influence on the surrounding environment. The use of this method effectively solves the problem that a large area of construction site cannot be provided for foundation pit excavation in the urban core area.

[0003] The mechanical tunneling type sinking well method controls the sinking of the shaft well by steel strands. When the surrounding soil collapses and forms a phenomenon of "wrapping" the well, the frictional resistance increases, and the well cannot sink relying on its own weight, resulting in the well being stuck, thereby affecting the construction progress of the shaft. At the same time, the difference in underground soil layers will cause the asymmetry of soil pressure and the uneven friction of the soil layer on the well, thereby causing the well to tilt, and the posture cannot be adjusted relying on the steel strand pulling, resulting in poor verticality of the shaft, affecting the construction quality, and increasing the construction difficulty of subsequent processes. SUMMARY

[0020] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0021] Example: Figs. 1-3 As shown, this embodiment relates to a mechanical tunneling shaft auxiliary sinking and attitude control system 50. The shaft auxiliary sinking and attitude control system 50 is installed inside the tunneling machine hoist 10. Multiple tunneling machine hoists 10 are provided around the shaft 70 (3 in this embodiment, evenly distributed at 120°). Correspondingly, there are also 3 shaft auxiliary sinking and attitude control systems 50. In addition to the tunneling machine hoist 10, the shaft tunneling supporting equipment also includes a shaft hoist 20 and a pipeline frame 30. The tunneling machine hoist 10, shaft hoist 20 and pipeline frame 30 are all installed on the ring beam 40. The tunneling machine hoist 10 is used to hoist the tunneling machine 60, the shaft hoist 20 is used to hoist the shaft 70, and the pipeline frame 30 is used to extend and place the pipeline system on the tunneling machine 60.

[0022] like Fig. 3As shown, the shaft auxiliary sinking and posture control system 50 comprises a telescopic oil cylinder 5001, a clamp 5002, a guide 5003, a force transmission plate 5004, a vertical plate 5005 and a horizontal plate 5006. The vertical plate 5005 is connected to the heading machine lifter 10 through four positioning pins 5007 and a plurality of bolts. The positioning pins 5007 serve the purpose of positioning. The horizontal plate 5006 is welded on the top of the vertical plate 5005. The cylinder body 50011 of the telescopic oil cylinder 5001 is fixed on the bottom of the horizontal plate 5006. The telescopic rod 50012 is connected to the force transmission plate 5004. The cylinder body 50011 of the telescopic oil cylinder 5001 and the horizontal plate 5006 are bolted through a connecting plate 5011. The telescopic rod 50012 is driven by the telescopic oil cylinder 5001 to move vertically, thereby driving the force transmission plate 5004 to move vertically. The force transmission plate 5004 applies uniform downward pressure or eccentric load to the shaft 70 to realize the auxiliary sinking and posture adjustment of the shaft 70. The clamp 5002 is clamped to the cylinder body 50011 of the telescopic oil cylinder 5001. In this embodiment, two clamps 5002 are provided. Each clamp 5002 is composed of two half-round clamp assemblies. The two half-round clamp assemblies are connected through bolts. One end of each clamp 5002 (i.e. one half-round clamp assembly) is connected to the vertical plate 5005 through a fixing bracket 5013 to fix the cylinder body 50011 of the telescopic oil cylinder 5001.

[0023] One end of the guide 5003 is connected to the horizontal plate 5006 and the other end is connected to the force transmission plate 5004. The top of the horizontal plate 5006 and the vertical plate 5005 are connected through two first reinforcing ribs 5008. The bottom of the horizontal plate 5006 and the vertical plate 5005 are connected through two second reinforcing ribs 5009. The bottom of the horizontal plate 5006 and the second reinforcing rib 5009 are connected through two third reinforcing ribs 5010. The guide 5003 is arranged on one side or both sides of the horizontal plate 5006. In this embodiment, only one guide 5003 is provided and arranged on one side of the horizontal plate 5006. The guide 5003 comprises a guide sleeve 50031, a guide plate 50032 and a guide rod 50033. The top end of the guide sleeve 50031 is connected to the bottom of the horizontal plate 5006. The top end of the guide rod 50033 is installed in the guide sleeve 50031 and the bottom end is connected to the force transmission plate 5004. The guide rod 50033 can move in the guide sleeve 50031. The guide plate 50032 is fixed on the second reinforcing rib 5009. A guide hole is formed in the guide plate 50032 to allow the guide rod 50033 to pass through. When the telescopic rod 50012 is driven by the telescopic oil cylinder 5001 to move vertically, the guide rod 50033 can move in the guide sleeve 50031 and the guide plate 50032, thereby guiding the telescopic oil cylinder 5001.

[0024] The horizontal plate 5006 is provided with lifting lugs 5012 on both sides, facilitating hoisting of the shaft auxiliary sinking and posture control system 50, and further realizing disassembly and assembly of the shaft auxiliary sinking and posture control system 50.

[0025] As shown in the drawings, Figs. 1-3 the embodiment also has the following construction method:

[0026] Step one: as shown in the drawings, Fig. 1 a ring beam 40 is first constructed in the construction site, used for installing shaft boring machine supporting equipment, including a boring machine lifter 10, a shaft lifter 20 and a pipeline rack 30, wherein the boring machine lifter 10 is used for fixing the shaft auxiliary sinking and posture control system 50.

[0027] Step two: as shown in the drawings, Fig. 2 the shaft auxiliary sinking and posture control system 50 is fixed inside the boring machine lifter 10.

[0028] Step three: as shown in the drawings, Fig. 3 a sinking force is applied to the shaft 70 below by the telescopic oil cylinder 5001 on the shaft auxiliary sinking and posture control system 50, so as to assist sinking or adjusting the posture of the shaft 70. In the sinking of the shaft 70, when the shaft 70 cannot sink by relying on the self weight after the steel strand is lowered, the shaft auxiliary sinking and posture control system 50 uniformly distributed above the shaft 70 is used to apply a sinking force to the shaft 70, so as to assist sinking of the shaft 70. In the sinking of the shaft, when the shaft 70 tilts, the adjustment of the posture of the shaft 70 cannot be completed by relying on the lifting of the steel strand, the shaft auxiliary sinking and posture control system 50 close to the offset side is used to apply a biasing force to the shaft 70, so that the shaft 70 tilts to move in the opposite direction, and the posture of the shaft 70 is controlled.

[0029] The beneficial technical effects of the embodiment are:

[0030] (1) A sinking force is provided for the shaft, assisting sinking of the shaft, ensuring smooth construction, and avoiding delay of the construction period;

[0031] (2) The posture of the shaft is controlled, the offset amount of the shaft is reduced, and the perpendicularity of the shaft is improved;

[0032] (3) The construction quality of the shaft is improved, and the construction difficulty of the subsequent process is reduced.

[0033] Although the above embodiment has been described in detail with reference to the drawings, those skilled in the art can recognize that various improvements and changes can be made to the embodiment without departing from the scope of the claims, and therefore, detailed description is not given here.
