Problems solved by technology

The high-mobility push form of hydraulic jack + tracked small tank is adopted. The "hydraulic continuous jack" increases the dynamic performance of the hanging basket and reduces the frequent conversion of reaction force blocks. The "tracked small tank" changes the traditional hanging basket rowing sliding The walking is crawler rolling walking, which reduces the friction of walking and successfully solves the technical problem of low operating efficiency of the hanging basket

Embodiment Construction

[0028] The main structure of the walking system of the present invention is mainly composed of a walking track 1, a rear pulley 6, a small crawler tank 5, a hydraulic jack 3, front and rear supports of the jack, and a hanging basket. The tracked small tank 5 is also called the crawler type handling small tank under the trade name.

[0029] The hanging basket of the cantilever pouring arch bridge chooses the down-loaded inverted triangle hanging basket. The overall structure of the hanging basket is on the lower side of the concrete structure. A small crawler tank 5 is designed and installed on the hanging leg 7, and the front support 4 of the jack is set on the hanging leg 7 of the hanging basket. and be connected with the hydraulic jack 3, and the rear pulley 6 is set at the rear fulcrum of the main beam of the hanging basket. Utilize the effective combination of the continuous jack and the track to push the tracked small tank to realize the walking of the hanging basket.

Abstract

The invention provides a walking method for a cantilever pouring arch bridge hanging basket push type crawler small tank, which adopts a high mobility pushing form of a hydraulic jack + hanging basket + crawler small tank to realize the construction of a cantilever pouring arch bridge hanging basket. The hanging basket of the cantilever pouring arch bridge is selected as a bottom-loading inverted triangle hanging basket, and the overall structure of the hanging basket is on the lower side of the concrete structure; a small crawler tank is installed on the hanging legs of the hanging basket, and the front support of the jack is set on the hanging legs of the hanging basket and connected with the hydraulic jack, the rear pulley is set at the rear fulcrum of the main beam of the hanging basket. The invention solves the problem of low crawling efficiency of the hanging basket along the arc surface in the suspended cast arch bridge, improves the maneuverability and safety of the hanging basket, and accelerates the walking speed. This technology has the characteristics of safe, reliable, short cycle and convenient operation, etc. It is suitable for hanging baskets to walk on bridges with large slopes such as arch rings.

Description

technical field [0001] The invention relates to a construction technology for a cantilever pouring arch bridge, in particular to a walking method for a cantilever pouring arch bridge hanging basket push-up type crawler small tank. Background technique [0002] The construction technology of suspended cast arch bridges with hanging baskets is still under development in China. Currently, there are only two types of hanging baskets: the regular triangle hanging basket and the inverted triangle hanging basket. The hanging basket is suitable for the construction and crawling of the arch ring. Domestic hanging basket walking is mostly carried out on bridge decks with small slopes, and the technology of crawling on the arc of the arch ring is not mature enough, and the form is mostly borrowed from the walking form (traction type) of hanging baskets on cantilevered beam bridges. According to the walking statistics of various hanging baskets in China, the walking forms include manua...
