The invention provides an aluminum alloy superstructure block hoisting method, which comprises the following steps of (1) determining the quantity of multiple hoisting points, positions of multiple hoisting points and an integral hoisting method of an aluminum alloy superstructure block according to the weight of the aluminum alloy superstructure block, a structural form and a gravity core; (2) producing a hoisting bracket for hoisting the aluminum alloy superstructure block; (3) designing and installing temporary reinforcement onto the aluminum superstructure block according to the integral hoisting method; (4) installing one hoisting hanger on each position of multiple hoisting points; and (5) vertically joining the hoisting hangers with the hoisting bracket through a wire cable, and utilizing the hoisting bracket to carry out the multipoint vertical hoisting. According to the hoisting method, not only can the deformation control problem for hoisting the aluminum superstructure block be solved and sectional construction of the aluminum alloy superstructure block be realized, but also the hoisting hangers and the temporary reinforcement for the hoisting are convenient to disassemble, and the block hoisting time can be shortened.

The present invention relates to a method of constructing a band type fiber reinforcement material for a reinforced-soil retaining-wall structure which enables quick and easy connection of a band type fiber reinforcing material, provides various connection methods therefor, and prevents stress from being concentrated in a connection part with a facing member during the sinking of a reinforced soil body, including: inserting a band type fiber reinforcement material into reinforcement material insertion members provided in facing members standing at a front of a reinforced soil mass (G) such that the facing members are adjacent to each other in leftward and rightward directions; spreading the band type fiber reinforcement material on the reinforced soil mass and laying and hardening a backfill material on the band type fiber reinforcement material and the reinforced soil mass; and repeatedly carrying out the first step and the second step until a predetermined height is reached.

PURPOSE: A valve train for an internal combustion engine is provided to prevent the displacement force of the switching element from acting in the axial direction of the valve lifter shaft, thereby reducing abnormal twist and deformation of the valve lifter. CONSTITUTION: A valve train for an internal combustion engine comprises a main valve lifter which rotates around a valve lifter shaft(2) in a rotational direction(D) by a first cam of a cam shaft, and a switching valve lifter(20) which rotates around the valve lifter shaft by a second cam(21) of the cam shaft. The switching valve lifter comprises a switching element with a switching pin(31) and a stopper(32). The stopper is arranged in the main valve lifter or the switching valve lifter. The switching pin is guided to slide in the progress direction from the main valve lifter or the switching valve lifter, where the progress direction is vertical to the valve lifter shaft.
