The invention discloses a full-automatic anti-tipping device of a crane. The full-automatic anti-tipping device comprises supporting legs, hydraulic rods, a supporting mechanism, a fixing rod, a sliding rod, a telescopic spring, a fixing shaft, a clamping block, a rubber block, an abutting spring and an abutting mechanism. The full-automatic anti-tipping device has the advantages that the four supporting legs are detachably and fixedly connected with the four corners of the crane, under cooperation of the four hydraulic rods, the crane can be supported and stabilized, and the crane is prevented from rolling over; meanwhile, by pulling the sliding rod, the bottom of the sliding rod is clamped with the clamping block on the bottom side of the hydraulic rod, and under the action of the fixingshaft and the rubber block, the sliding rod is tightly clamped and is not prone to loosening, then under the action of the abutting mechanism, the sliding rod and the inside of the fixing rod cannotslide, and the supporting and reinforcing effects between the hydraulic rods and the supporting legs are achieved; and when the fixing rod is not used, the abutting mechanism is driven to store the sliding rod, then the fixing rod is rotated, and the fixing rod and the sliding rod are stored.

The invention discloses a steel bridge capable of being used as a supporting and reinforcing structure, comprising an inclined bridge body and steel columns for supporting the bridge body, wherein a bridge head is supported on a crown beam at the top of a supporting structure of a foundation pit; bridge feet are supported at the bottom of the foundation pit; the bottom face of the bridge head is fixedly connected with a force transmission cross beam which extends along the width direction of the bridge body; the front side face of the force transmission cross beam is mutually adhered to the side face of the crown beam; an inclined supporting rod is arranged between the force transmission cross beam and the bottom of the foundation pit; the upper end of the inclined supporting rod is fixedly connected with the force transmission cross beam; and the lower end of the inclined supporting rod is fixedly connected with the foundation pit. According to the steel bridge, the supporting structure of the bridge head can be effectively supported and reinforced, and an independent reinforcing structure or supporting structure does not need to be arranged, so that the engineering cost is greatly reduced.

The invention relates to a three-dimensional compression bag, and belongs to the technical field of vacuum compression storage articles. The three-dimensional compression bag comprises a compression bag body and an extraction valve, wherein the compression bag body is of a cubic structure, each edge of the compression bag body is provided with a supporting edge, and the extraction valve is arranged on the compression bag body; and by adopting the structure, the supporting edges form the cubic structure, all bag faces of the compression bag body are effectively supported, stored objects are prevented from deforming, the bag faces of the compression bag body compress the stored objects under the action of negative pressure in the air exhaust process, the supporting edges have certain stiffness and cannot be pressed to deform, and the peripheries of the bag faces of the compression bag body are evenly pulled by the supporting edges at the corresponding positions, so that the compression bag body can keep flat during compression, stored articles cannot be wrinkled and extruded into a ball, the supporting edges of the three-dimensional compression bag can support and reinforce the three-dimensional compression bag, multiple three-dimensional compression bags can be conveniently stacked and stored, and the space can be saved.

This application relates to the field of foundation pit support, in particular to a foundation pit support structure and its construction method. The side wall of the protective plate is provided with a channel for the support tube to be accommodated. The support tube is detachably connected in the channel, and the end of the support tube protruding to the channel is provided with a plurality of seepage holes. There is an adjustment component for adjusting the water seepage of the seepage hole inside the pipe. Both ends of the support pipe are closed ends. There is a drainage cavity inside the protective plate, and the drainage cavity is located under the channel. The channel is connected to the drainage cavity. One side of the support pipe is provided with a drainage hole, and the drainage hole is connected with the communication hole. A drainage pipe is communicated, and a suction pipe is communicated between the water pump and the drainage chamber.

The present application relates to the field of construction engineering, in particular to a method for reducing the bending damage of pipe piles in soft soil, which includes the following steps: step 1: survey and detection of the soil layer on the construction site; step 2: set the first layer of reinforcement at the position of the design elevation Step3: Set the second reinforcement layer at the design elevation, and the second reinforcement layer is located above the first reinforcement layer; step4: Drive at least two pipe piles into the soil layer, and the pipe piles pass through the second reinforcement layer in turn layer and the first reinforcement layer; step5: test the bearing capacity of the pipe pile; step6: acceptance. In the present application, a first layer of reinforcement layer and a second layer of reinforcement layer are set in the soil layer in advance, and the two reinforcement layers form a restraint body for the pipe pile at the set elevation, which can support and strengthen the pipe pile, thereby reducing the amount of soil The bending damage of the pipe pile by the layer pressure can maximize the bearing capacity of the pipe pile in the soft soil, and at least two pipe piles are arranged in the two reinforcement layers, which can improve the overall bearing capacity of the pipe pile.

The invention discloses a multi-purpose steel structure decorative ceiling and an assembling and construction method thereof, comprising an inner wall and a steel structure roof frame, a limit cylinder is installed at the bottom end of the steel structure roof frame, and the inner wall is on one side of the limit cylinder, and A guide pulley is installed at the bottom end of the steel structure top frame on the other side of the limit cylinder, a top plate is rotatably installed on the upper surface of the inner side wall of the inner wall, and an insertion rod is installed at the top of the top plate through the limit part to limit the movement, and the insertion rod is connected with the rod. A plug-in mechanism is installed between the limit cylinders, the top plate is provided with a multi-purpose half hole on the surface of one end away from the inner wall, and a traction mechanism is installed between the multi-purpose half hole and the guide pulley, and the bottom end of the top plate under the multi-purpose half hole is installed. light frame.
