[0057] In the embodiment of the present invention, considering the safety of shaft construction, the hanging platform is arranged as a double-layer hanging platform, and the distance between the two hanging platforms is 4m. The main beam of the hanging platform uses I16 I-beam, the secondary beam uses 16 channel steel, the support column uses I16 I-beam, the round beam uses 16 channel steel, the plate surface uses 4mm patterned plate, the support column 16 is connected to the main beam of the upper hanging platform 14 and the lower hanging platform 15 by welding and bolting, and a ladder 17 is welded on one of the support columns to facilitate the construction personnel to go up and down. Angle steel is welded at both ends of the main beam and the secondary beam as the bolt connection part, the main beam and the ring beam are directly welded, and the connection between the ring beam and the main frame must be firm, and welding reinforcement is required after tightening with bolts.

[0058] Among them, the double-layer hanging plate device 1 is converted in time according to the well construction section. After the lower section of the well is converted, the size of the hanging plate becomes larger, and it is necessary to set a movable wing plate 19 on each hanging plate. The movable wing plate 19 should be retracted during the movement of the hanging plate to prevent the accident of the movable wing plate hanging on the side. Four buckles 20 are welded on the four middle steering wheels of the movable wing plate 19. When the hanging plate swings at the construction site, four φ40×3.5mm steel pipes are added to the buckle 20 to fix it to the wall to achieve stability.

[0059] exist Figure 3 and Figure 4 In the illustrated embodiment, the sheave platform 21 includes a sheave base, a main beam and a secondary beam arranged on the sheave base, the main beam and the secondary beam are welded to each other by full welding, and the sheave base is connected to the secondary beam by bolts; the main beam on the sheave base is fixed in the tunnel of the main chute by the anchor rod.

[0060] Specifically, eight anchor rods are constructed at designated locations on both sides of the tunnel in strict accordance with the design height to fix the main beam of the overhead sheave platform. The anchor rods are made of φ36mm round steel, with an anchoring depth of 1.5m and an exposed length of 0.5m. Anchoring agents are used for anchoring. The main beam of the overhead sheave platform 21 is made of I28mm I-beam, and the secondary beam of the overhead sheave platform 21 is made of I28mm I-beam. The main beam of the overhead sheave platform 21 and the anchor rods are welded with 10mm thick steel plates and connected with high-strength bolts. The main beam of the overhead sheave platform 21 and the secondary beam of the overhead sheave platform 21 are fully welded and reinforced with high-strength bolts; and the overhead sheave base and the secondary beam of the overhead sheave platform 21 are connected with high-strength bolts.

[0061] exist Figure 3 and Figure 4 In the illustrated embodiment, the derrick 22 comprises upper columns, lower columns, scissor braces arranged between the upper columns and between the lower columns, and diagonal braces for supporting the upper columns, wherein the angle between the diagonal braces and the upper columns is 3° to 4°; the upper columns and the lower columns are fixed by welding with steel plates; the upper columns are welded to the sheave platform by steel plates; the lower columns are installed in holes reserved at the wellhead, fixed to the ground by round steel anchor rods, and then poured with concrete. Specifically, the columns of the derrick are made of I16mm I-beams with full welding, and the two sections of the columns are firmly welded to the 16mm thick steel plate. The upper section of the column is fully welded to the I28mm I-beam of the sheave platform 21 through the steel plate and then connected with bolts. The lower section of the column is buried in the reserved hole at the wellhead, fixed to the ground with φ36mm round steel anchor rods and poured with concrete. The anchoring depth is 1.5m. [16 channel steel is used as scissor braces between the columns and is firmly welded. In order to ensure the force balance of the derrick, I16 I-beams are used as diagonal braces for the derrick on one side of the winch. The angle between the column and the diagonal brace should not be too large, 3° to 4° is appropriate. The diagonal brace and the column are reinforced by welding φ159mm steel pipes to ensure that the derrick and the sheave platform are firm and reliable as a whole.

[0062] In addition, during the construction process, the fixing method of the well wall pipeline is as follows: the air supply pipe for construction is φ25×3.5mm, the water supply pipe is φ25×2.5mm, and the ash pipe is φ159mm seamless steel pipe. The wellhead uses a 24.5mm steel wire rope to suspend the upper end of the pipeline and fix it through the end wall anchor rod and the column of the well frame. The well uses a Φ36mm round steel anchor rod with a high-strength bolt to support the pipeline flange, with an interval of 6 meters, and the anchor rod anchoring depth is not less than 500mm. The concrete conveying pipeline must be vertical, and the flange of the coupling is perpendicular to the axis of the steel pipe, otherwise it will cause rapid wear of the steel pipe. During the construction process, all pipelines are regularly inspected, and if tilted or damaged, they are immediately corrected and repaired. The upper end of the lighting, signal, and blasting cables are fixed with steel wire ropes. Since it is difficult to replace the pipeline in the wellbore, a screen is set at the uppermost entrance of the conveying pipe to prevent large-sized stones and debris from clogging the pipeline. Among them, hanging anchor rods are constructed at appropriate locations in the wellhead tunnel. The anchor rods are made of φ22 round steel with a length of about 1m. Lighting, signal and blasting cables are also fixed on the wire rope.

The winch 23 and the stabilizing car 24 are respectively fixed to the ground through a base and poured with concrete. Specifically, the winch suspends the bucket as a means of getting people up and down, while lowering steel bars and manganese steel plates to transport construction materials to the hanging plate. The suspended hanging plate is lifted by two JZ-16 / 1000 stabilizing cars. Before installing the winch 23 and the stabilizing vehicle 24, the ground is cleaned to a hard bottom at the designated location, and C25 concrete with a thickness of not less than 500mm is poured as the foundation. The base of the winch 23 and the stabilizing vehicle 24 is made of I16mm I-beam, and is firmly connected to the winch 23 and the stabilizing vehicle 24 by welding and bolting. Anchors are arranged around them for reinforcement and concrete pouring to form a whole. The anchors are made of φ36mm round steel with an anchoring depth of 1.5m. The upper part is made into a hook shape to fix the winch 23 and the stabilizing vehicle 24. The winch wire rope 5 is 18*7-20-1670 non-rotating wire rope, and the stabilizing vehicle wire rope 6 is 18*7-24.5-1670 non-rotating wire rope.
