Embodiment Construction
[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] Such as Figure 1-4 As shown, the closed box for drilling piles of the present invention includes: a cavity 1, a rear foot plate 2, an I-beam 5, 3 wire meshes 6 and 3 support plates 3 installed in the cavity 1 and 3 hydraulic cylinders 4. The cavity 1 is in the shape of a cuboid with a length of 800-900mm, a width of 550-650mm, and a height consistent with that of the sheet pile, and an opening is formed on the rear panel. The plurality of support plates 3 are fixedly mounted at intervals from top to bottom. The inner side of the front panel of cavity 1 is used to reinforce the closed box. The cylinder body 8 of each hydraulic cylinder 4 is installed horizontally on a supporting plate 3 respectively, and the piston rods 7 of multiple hydraulic cylinders 4 are all fixedly mounted on the said rear foot plate 2 placed longitudinally. The shape and size of the...

Abstract
The invention discloses a sealing box and a construction method for boring and pile-planting. The sealing box comprises a cavity body, a back foot plate, I-shaped steel, a plurality of steel wire nets, a plurality of supporting plates installed in the cavity body and a plurality of hydraulic cylinders disposed in the cavity body, wherein the cavity body is cuboid-shaped; an opening is formed in the back panel of the cavity body; the plurality of supporting plates are fixed on the inner side of a front panel of the cavity from up to bottom at intervals; a cylinder body of each hydraulic cylinder is horizontally installed on one supporting plate; piston rods of the plurality of hydraulic cylinders are fixed on the back foot plate; the shape and size of the back foot plate are adaptive to the opening in the back panel of the cavity and seal the opening; two I-shaped steel is provided and longitudinally arranged on two sides of cylinder bodies of the plurality of hydraulic cylinders in a symmetric way; and the front panels of the cavity between two adjacent supporting plates are respectively provided with one steel wire net. The invention further discloses a construction method for boring and pile-planting via the above sealing box. Great sheet-pile wall water-resisting effect can be achieved by the use of the sealing box for boring and pile-planting.
Description
technical field [0001] The invention relates to the technical field of construction, in particular to a closed box for drilling piles and a construction method. Background technique [0002] Drilled pile planting method is to use a drilling rig to form a hole on the pile position according to the requirements of the designed aperture and hole depth, and drill through a certain thickness of hard interlayer soil, and remove the soil in the drilled hole through wet or dry row. After being transported out of the construction site, after the hole is formed, the sheet pile is implanted in the hole, and the pile tip is generally driven into the bearing layer level by hammering. However, in the conventional construction process, this technology may cause mud and sediment to enter the gap between the sheet piles during the hole forming process, making the water-stop effect of the sheet pile wall after grouting unsatisfactory. Contents of the invention [0003] An object of the pre...
