Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] A three-dimensional space supporting beam lattice structure for restricting the displacement of bank walls and wing walls on both banks of a river, comprising bank walls and wing walls structures 1 on both banks, and a river bed bottom protection structure 2, characterized in that: combined with a river bed bottom protection structure 2 (masonry or Reinforced concrete shielding, etc.), vertical and horizontal reinforced concrete hidden beams are arranged in the middle of the structure, and the two ends of the horizontal hidden beams 3 are supported on the front toe of the bottom plate of the bank wall and wing wall structure 1 on both banks.

[0020] The intersection of the longitudinal concealed beam 4 and the transverse concealed beam 3 is rigidly connected, and short piles 5 are arranged under the intersection to form a vertical constraint and ...

Abstract

The invention relates to a three-dimension support beam structure for limiting the displacements of river bank and wing wall, wherein it combines the riverbed protective structure (masonry or steel bar concrete protector), arranges longitudinal and transverse steel bar concrete hidden beam, while two ends of transverse hidden beam are supported at the front finger of bottom plate, and the cross point of longitudinal and transverse hidden beams has short post below, to form vertical limit, to limit the deformation of compress rod caused by the axial pressure of two side support structures, to form three-dimension steel bar concrete support beam, wherein said bank and wing walls can be light one, suspended arm, held arm or low-rigidity support cam type. The invention can reduce the span of horizontal beam, increase the rigidity of beam, reduce the size of beam, and reduce the number of post foundations.

Description

technical field [0001] The invention relates to the technical field of support structures for bank walls and wing walls on both banks of a river channel, in particular to a three-dimensional space supporting beam lattice structure that limits the displacement of bank walls and wing walls on both sides of a river channel. Background technique [0002] At present, the engineering technical measures to control the displacement of the quay wall and the wing wall on the soft soil foundation are analyzed from the principle point of view, generally increasing the structural stiffness of the quay wall and the wing wall and reducing the earth pressure behind the quay wall and the wing wall. Increasing the stiffness of the quay wall and the wing wall means increasing the structural size of the quay wall and the wing wall, which is very effective for the stability of the quay wall and the wing wall, but the effect of limiting the displacement of the quay wall and the wing wall is not ob...
