Problems solved by technology

[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

Embodiment 1

[0036] The present invention proposes a square caisson waterproof canopy, which is suitable for square caissons, such as square multi-section cast-in-place reinforced concrete caissons and the construction state design of similar wells; the square caisson canopy of the present invention The shed is detachably installed on the inner wall of the square caisson well, which avoids the rise of the groundwater level caused by the infiltration of rainwater from the upper part or reactive labor (clearing snow in the well), and effectively protects the equipment and facilities in the well. figure 1 Shown the plan view of two square caissons 1 arranged side by side, will be illustrated below with the single square caisson 1 that square caisson canopy 2 of the present invention is installed, wherein, the length of square caisson 1 is 7760mm, width 6500mm (see details figure 2 ); take the length direction of the square caisson 1 as the length direction, take the width direction of the sq...

Embodiment 2

[0045] refer to figure 2 with Image 6 , the present invention also provides a method for installing the square caisson waterproof canopy used in embodiment 1. When the concrete reaches more than 50% of the design strength, the waterproof canopy can be installed. The above-mentioned installation method includes:

[0046] To lay out the line, determine the position of the C-shaped guide rails 23, carry out the leveling and lay-out on both sides of the shaft wall 8, and determine the position of the expansion bolt 3, and ensure that the two C-shaped guide rails 23 after installation are in the same horizontal plane;

[0047] Insert a plurality of pulleys 22 into the guide rail 23, and fix the C-shaped guide rail 23 to the inner wall surface of the caisson well wall 8 by using the expansion bolt 3 according to the setting-out positioning;

[0048] Connect and fix the connector 241 with the pulley; the wire rope 243 is connected and fixed by the connector 241 on both sides of th...

Abstract

The invention provides a square caisson waterproof canopy. The square caisson waterproof canopy comprises a raincloth, a plurality of pulleys fixed to the raincloth, a pair of guide rails for the multiple pulleys to slide, and a connection opening and closing device, wherein the guide rails are fixed to the wall of a caisson symmetrically; the connection opening and closing device comprises connectors and an opening and closing component connected to the connectors, and the connectors are used for connecting the raincloth with the pulleys; and the square caisson waterproof canopy comprises a plurality of steel wire ropes arranged at intervals and playing a role in support. According to the square caisson waterproof canopy, the influence of severe weather, such as rain and snow, on the caisson construction can be avoided effectively, and construction equipment in the caisson is protected; the repeated labors are reduced, and the normal construction conditions in a bottom hole are ensured; and the construction efficiency is improved greatly, and the safe and civilized management effect and level of the construction are further improved greatly.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a square 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, in...
