Circular open caisson waterproof canopy

Abstract

The invention provides a circular open caisson waterproof canopy. The circular open caisson waterproof canopy comprises rainproof cloth, a plurality of pulleys, two linear-shaped guide rails, a triangular supporting frame and a connecting opening and closing device, wherein the pulleys are fixed to the rainproof cloth, the two linear-shaped guide rails are used for sliding of the multiple pulleys,and the triangular supporting frame is used for fixing the guide rails; the rainproof cloth comprises a first part and two second parts, wherein the first part is positioned in the central area, andthe two second parts are positioned at the peripheral areas of the two sides; the two guide rails are symmetrically fixed on the caisson wall of an open caisson; the connecting opening and closing device comprises connecting pieces and an opening and closing assembly connected with the connecting pieces, and the connecting pieces are used for connecting the rainproof cloth and the pulleys; and thecircular open caisson waterproof canopy further comprises a plurality of steel wire ropes which are arranged at intervals and play a role in supporting. The circular open caisson waterproof canopy can effectively prevent influence of severe weather such as rain and snow on construction of the open caisson, protect construction operation equipment in the caisson, reduce repeated use of labor, guarantee the normal construction operation conditions of the caisson bottom, greatly improve the construction efficiency, and also greatly improve the safety and civilization management effects and levels of the construction.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a circular caisson waterproof canopy. Background technique [0002] The caisson is generally made into a shaft-shaped or rectangular structure on the surface, and then under the maintenance of the well wall, the soil is continuously excavated from the well to make the caisson gradually sink under the action of its own weight. The back cover builds the internal structure. [0003] During the construction of caissons and similar underground spaces, since some small and medium-sized electromechanical equipment, earthwork equipment, and operating tools need to be left in the underground working layer for a long time, some equipment is not suitable for frequent lifting and transportation to the ground when encountering rainy and snowy weather It is not convenient to effectively cover underground; at the same time, the underground space is as dry as possible. Therefore, ...

[0003] During the construction of caissons and similar underground spaces, since some small and medium-sized electromechanical equipment, earthwork equipment, and operating tools need to be left in the underground working layer for a long time, some equipment is not suitable for frequent lifting and transportation to the ground when encountering rainy and snowy weather It is not convenient to effectively cover underground; at the same time, the underground space is as dry as possible. Therefore, in order to ensure that the underground equipment and facilities are not damaged by rain and snow, and to reduce rain and snow falling into caissons and similar underground spaces, it is necessary to take measures overall shielding measures
