Embodiment Construction

[0049] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] like Figure 1 to Figure 8 As shown in the figure, the embodiment of the present invention proposes a non-destructive in vitro dismantling method of a bridge hollow pier top construction support and a formwork, which includes the following steps:

[0051] S1. Surface pretreatment of hollow pier: When constructing the last section of concrete of hollow pier 1, install a rectangular tube welded by four steel plates on its side surface near the top opening of hollow pier 1 to form the first through hole 2, The second through holes 3 and the fourth through holes 20; wherein the first through holes 2 are provided with four pieces, and the four first through holes 2 are paired in pairs and arranged symmetrically with respect to the hollow pier 1; the second through holes 3 is arranged above the first through hole 2, and the ex...

Abstract

The invention relates to the field of bridge pier column construction, in particular to a bridge hollow pier top construction support and formwork lossless in-vitro demolition method.The bridge hollow pier top construction support and formwork lossless in-vitro demolition method comprises a bearing frame arranged on the surface of a hollow pier in a penetrating mode and a supporting plate, the supporting plate is movably arranged on the upper surface of the supporting plate in the vertical direction, and an adjusting piece used for adjusting the height of the supporting plate is arranged on the bearing frame; after the height of the supporting plate is randomly adjusted by the adjusting piece, the bearing frame can support the surface of the supporting plate in the vertical direction; by the adoption of the technical scheme, the problems that in the prior art, cost is high and the construction date is long when a plurality of hollow piers are capped can be solved, use is easy, the manufacturing cost is low, and efficiency can be improved when the hollow piers are capped.

Description

technical field [0001] The invention relates to the field of bridge pier column construction, in particular to a non-destructive in vitro dismantling method of a bridge hollow pier top construction support and a template. Background technique [0002] In order to reduce the self-weight of the pier body, or to ensure that the pier has a small inertial force during earthquakes, or to reduce the load of the pier on the weak foundation, the piers of highway and railway bridges often use hollow piers, and the top of the hollow piers is a solid concrete structure, which needs to be solved. During the construction of the solid section at the top, the vertical support of the hollow part of the hollow section is the problem; the currently commonly used construction methods are roughly divided into the following categories: [0003] 1. Set up a steel pipe frame or scaffolding in the hollow pier, use the erected scaffolding as a load-bearing structure for construction and transportatio...
