Embodiment Construction

[0025] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0026] combine Figure 4 — Figure 7 As shown, a fast and efficient construction method for bridge hollow pier diaphragms without supports, including the following steps:

[0027] Step A, constructing reinforced concrete supporting corbels while constructing bridge hollow piers.

[0028] When binding the reinforcement cage of the hollow pier 1 of the bridge, the reinforcement cage of the reinforced concrete support corbel 3 is bound together, and two left and right opposite reinforced concrete support corbels 3 are arranged at the chamfering position on the top of the bridge hollow pier 1 .

[0029] The reinforcement cage of the reinforced concrete supporting corbel 3 is embedded and tied into the reinforcement cage of the bridge hollow pier 1, and after being integrally bound with the reinforcement cage of the bridge hollow pier 1, it is poured integra...

Abstract

The invention discloses a support-free rapid and efficient construction method for a bridge hollow pier partition plate. The support-free rapid and efficient construction method comprises the following steps that A, a reinforced concrete supporting bracket is constructed while a bridge hollow pier is constructed; B, the reinforced concrete prefabricated slab is hoisted into a pit in the top of the bridge hollow pier; C, mortar filling is performed; and D, the reinforced concrete prefabricated slab serves as a construction platform for construction of the bridge hollow pier partition plate. According to the construction method, during construction of the hollow pier partition plate, support-free construction of the hollow pier partition plate can be achieved, the problem that a hollow pier partition plate supporting system is difficult to erect is effectively solved, the supporting bracket and the prefabricated slab form a whole with the hollow pier after construction is completed, the supporting system does not need to be manually dismantled, and the construction efficiency of the hollow pier partition plate is improved; and meanwhile, the labor and material cost of the supporting system is reduced, and important practical significance is achieved for safe and efficient construction of the hollow pier partition plate.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a support-free rapid construction method for a bridge hollow pier partition. Background technique [0002] The construction of high bridge piers is an important part of bridge construction, and the construction of hollow pier diaphragms is the difficulty and focus in the process of bridge high pier construction. combine figure 1 As shown in -3, the high pier 1 of the bridge adopts a hollow pier, and a hollow pier partition 2 is erected between the upper and lower adjacent hollow pier sections, and a manhole 2a needs to be provided at the center of some hollow pier partitions 2, Some hollow pier partitions 2 do not need to be provided with manholes, and the top of the hollow pier is provided with chamfers 1a corresponding to the left and right ends of the hollow pier partition 2 . [0003] At present, in the construction of hollow pier partitions of bridges in China,...
