The invention provides a drilling, loading, transporting and anchoring integrated machine with dual platforms and four arms for a coal roadway, comprising a caterpillar travel part, an engine body platform, four drill arm parts, four hydraulic drilling rig parts, a provisional supporting device, a hydraulic and operation system, a pump station part, a rear support part, a shovel plate part, a first conveyor and a second conveyor and being characterized in that the integrated machine also comprises a lifting platform and a platform lifter; the platform lifter is arranged on the engine body platform, and the lifting platform is connected above the platform lifter; four drill arm parts and four hydraulic drilling rig parts are installed at the rear sides of the upper and lower parts and the left and right sides of the lifting platform; and the provisional supporting part is fixedly installed on the front end of the lifting platform. The integrated machine in the invention can complete all procedures such as drilling, coal loading, coal transporting, anchor bolts and anchor cables construction, provisional supporting and the like, and improves the centrality, flexibility and systematicness of tunneling equipment, thus reducing mechanical handing, installing and dismounting operations on headwork faces, lowering labor intensity for workers and increasing work efficiency of tunneling.

The invention relates to the technical field of civil engineering construction, in particular to a concrete pouring mechanism, which solves the work needs of the prior art that the working radius of concrete pumping cannot be reached, the local construction of civil engineering, and the small amount and temporary concrete pouring, and solves the problem. In construction, it is time-consuming and laborious to rely on workers to mix and run concrete. A concrete pouring mechanism includes a base, a mixing box is fixedly connected to one side of the top of the base, the bottom of the mixing box is fixedly connected to the top of the base, a driving motor is fixedly connected to the top of the mixing box by bolts, and an inner cavity of the mixing box is provided. There is a stirring rod. The invention uses the pushing of the mixing blade and the suction of the piston to push the concrete, and through the universal rotation mechanism of the long discharge nozzle, the flexibility of the conveying direction of the concrete is improved, and the pouring rate of the concrete is improved; the mixing box The uninterrupted operation of the inner mixing blade effectively avoids the segregation of aggregates and ensures the uniformity of the concrete material composition.

The invention discloses a mounting, burying and grouting method for a multi-point displacement meter. According to the mounting, burying and grouting method, holes are drilled in rock stratums of different conditions, and the displacement meter is mounted at multiple points. The mounting, burying and grouting method comprises the steps of rock stratum displacement monitoring in the horizontal direction, in the vertical direction, in the slanted upward direction and in the slanted downward direction. A double grouting method is adopted in the displacement meter, namely, the displacement meter is provided with a vent pipe, a far-end anchor head, a near-end anchor head and double grouting pipes. The mounting, burying and grouting method for the multi-point displacement meter can be applied to displacement safety monitoring in building projects and construction such as water conservancy and hydropower projects, highways and railways, the problem that the grouting of the multi-point displacement meter is insufficient under different rock stratum conditions is solved, the rock mass deformation of the measured part can be reflected truly by the displacement meter, and reliable monitoring data are supplied to the buildings.

The invention belongs to the technical field of water conservancy construction, and relates to a construction method for reconstructing a cofferdam anti-seepage system in an immersed tube tunnel. The construction method comprises the steps that remaining sand-filled long pipe bags and a river bed after an original primary cofferdam is destroyed by rush of river are adopted as a base, and stones are thrown at two sides of the base to form an inner side riprap cofferdam body and an outer side riprap cofferdam body; the space between the inner side riprap cofferdam body and the outer outside riprap cofferdam body is filled with clay to form a first-level clay cofferdam body, the inner side riprap cofferdam body, the outer side riprap cofferdam body and the first-level clay cofferdam body form an earth-rock cofferdam, and after the construction of the earth-rock cofferdam, a second-level clay cofferdam body is constructed above the earth-rock cofferdam through filling; and plastic concrete drilling occlusion piles are constructed in the middle part of the first-level clay cofferdam body as the anti-seepage system of the earth-rock cofferdam. According to the construction method, the cofferdam can be quickly reconstructed on the basis of the remaining sand-filled long pipe bags and the river bed remaining after the original primary cofferdam is destroyed by rush of river, the stable earth-rock cofferdam and the anti-seepage system thereof are formed, and remaining civil engineering in the cofferdam is guaranteed to reach the construction condition of no-water operation.

The present invention belongs to the field of building engineering pile construction technology. The building engineering pile constructing process includes the following steps: 1. making prefabricated spiral concrete pile with middle core hole; 2. setting the core pulling tool inside the core hole; 3. fixing the pile cap to the core pulling tool and the upper end of the prefabricated spiral concrete pile; 4. hoisting and driving the pile cap to drill; and 5. grouting the outside of the prefabricated spiral concrete pile through the core hole. The apparatus for the construction includes prefabricated spiral concrete pile with middle core hole, core pulling tool inside the core hole and pile cap fixed to the core pulling tool and the upper end of the prefabricated spiral concrete pile. The present invention can suit for different soil qualities and has low engineering cost, simple construction and high reliability.
