Abstract

The invention provides a box culvert jacking device which comprises a box culvert, three layers of steel gratings, jet concrete, four rows of pipe curtains and joist steel.The four rows of pipe curtains are arranged to be a hollow cube, every two adjacent upper-row pipe curtains are connected through the corresponding joist steel, every two adjacent left-row pipe curtains are connected through the corresponding joist steel, every two adjacent right-row pipe curtains are connected through the corresponding joist steel, one layer of steel gratings are connected with the row of pipe curtain located on the upper portion in the hollow cube, the other two layers of steel gratings are connected with the two rows of pipe curtains on the two side faces in the hollow cube respectively, each layer of steel gratings are filled with jet concrete, and the box culvert is inserted into the hollow cube.The invention further provides a box culvert jacking method.By means of the box culvert jacking device, difficulty appearing in construction can be overcome, and higher benefits can be created.By means of the box culvert jacking method, subgrade settlement can be effectively controlled, and the method is suitable for box culvert jacking under the hard geological condition.

Description

technical field [0001] The invention relates to a box culvert jacking device. Background technique [0002] The currently known box culvert jacking construction technology is soil jacking. This construction method needs to set up a working pit in the jacking site first, make a slide plate at the bottom of the pit, prefabricate a reinforced concrete box culvert on the slide plate, and make the front end of the box culvert. The protruding edge, then build the back not far from the box culvert, then install a jack between the back and the bottom plate of the box culvert, and at the same time reinforce the road that needs to pass through, and finally the jack will use the reaction force of the back to push the The box culvert goes into the subgrade. When jacking, the edge of the front edge of the box culvert is continuously excavated, and the jacking is followed by digging until the box culvert is completely jacked into the subgrade. [0003] With the rapid development of urba...
