SU1216275A1 - Water-protecting arrangement for constructing plate of high pile raft foundation of bridge pier - Google Patents

Description

The invention relates to the field of bridge and hydro technical construction and can be used to construct a high pile grillage plate on deep watercourses.

The purpose of the invention is to reduce the material consumption of the device and ease of production.

FIG. 1 shows the proposed device, a cross section; FIG. 2 shows section A-A in FIG. one.

A device, for example, a circular outline in plan includes a rigid frame with lower 1 and upper 2 along the rigid bond 3 connected to each other, wooden floor 4 cement concrete 5, flexible element 6, which bend around the lower one with 1 rigid frame with external the sides are fixed on the upper cross section of the rigid frame and on the support ring 7. Spacers 8 are installed between the flexible elements b and the sheet pile wall, which deflect the flexible elements inside the device.

The device is mounted on pre-immersed piles x 9 and secured through 6anKfi 10 laid on top of piles 9 on drafts 11. The water walls of the device are made of a tongue 12 mounted on brackets 13 attached to the bottom of a rigid frame 1 and built wooden flooring 14 and a supporting beam 15.

The device works as follows.

When laying cement concrete vertically moving

15 pipes, part of the weight of the laid concrete through the flooring, the flexible elements and the spacers deflecting the flexible elements into the inside of the fence is transmitted to the inside of the waterproof

20- walls. After the cement concrete has set the required strength, water is pumped out of the barrier, and the water pressure is perceived by the joint working waterproof wall, flexible elements and struts.
