Embodiment

[0029] Embodiment: This embodiment specifically relates to a high-level trestle structure arranged on steep bare rock without covering in deep-water rapids. This kind of high-level trestle structure is suitable for deep-water rivers, high flow rates, mountainous rivers with high flood seasons, rivers without covering layers, and riverbeds. It is a steep or inclined hard bare rock hydrogeological condition. This embodiment will take the Qianjiang Super Bridge Project as an example to describe in detail. The Qianjiang River is a mountainous river with a large flow rate and rapid flow. The maximum flow rate reaches 3.21m / s. The riverbed has no cover layer. 80 MPa, extending all the way to the shore, the riverbed within 65m near the shore is steep, the rock face is inclined at 35-53°, and the rock face at the pier in the water is inclined at about 25°, and the river bed is undulating and full of stalagmites. In order to make it easier for construction workers to enter the bridge p...

Abstract

The invention belongs to the field of bridge construction and particularly relates to an overhead trestle structure built on non-covering steep bare rocks in deep rapids. The invention adopts the technical scheme that the overhead trestle specifically comprises a trestle body and steel pipe piles for supporting the trestle body, wherein the steel pipe piles are arranged on the surfaces of the steep bare rocks, bottom cavities of the steel pipe piles are connected and anchored with the steep bare rocks by anchor rods in a connected way, and the steel pipe piles, the steep bare rocks and the anchor rods are fixedly connected into an integral structure by a poured underwater concrete layer. The overhead trestle structure has the advantages that the steel pipe piles are connected with the surfaces of the steep bare rocks by a grouted and rock-socketed anchor rod structure, so that the steel pipe piles are firmly anchored to the surfaces of the steep bare rocks by the holding force of underwater concrete pulp andwith the holding force of the anchor rods, pile bottom concrete and river bed rocks; and the construction has a short period, is at a low cost and is safe and efficient.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a high-level trestle structure arranged on steep bare rock without covering layer in deep-water rapids. Background technique [0002] With the development of social economy, the demand for convenient transportation is becoming more and more intense, and there are more and more bridge projects built on various geology. In the construction of bridge water foundation, trestle bridges are widely used as construction channels for materials, equipment and personnel. Domestic trestle bridges mostly adopt the structural method of steel pipe piles and Belay trusses. However, the trestle bridges in the past were generally built on rivers and lakes with thick covering layers. Under such geological conditions, the foundation construction of the trestle bridge leading to the main project is generally carried out by the traditional "fishing method", that is, to place steel pipe p...
