Abstract
The utility model provides a fishway structure arrangement structure who combines with the protection of the important building of bank slope sets up the fishway structure at side slope toe, sets up fishway pond room on the major structure of fishway structure, and the major structure of fishway structure backfills stone ballast to fishway crest elevation between the major structure of fishway structure and the side slope after the excavation as side slope toe barricade, increases slope toe ballast. The utility model discloses make the fishway can combine the side slope excavation support construction completion of the important building protection of bank slope in construction preparation phase to become side slope protective structure's partly, reduce side slope excavation support engineering volume, reduce the construction interference, save the time limit for a project.
Description
Technical Field
The utility model relates to a fishway structure arrangement structure that combines with the protection of important building of bank slope. The structure mainly provides a structural arrangement form with good economy, high reliability and small construction interference for the arrangement of the hydroelectric engineering hub, and is suitable for the hydroelectric engineering with important building protection requirements on the hub bank slope.
Background
For hydroelectric junction engineering, protection of construction period and permanent side slope is a content which needs to be considered emphatically in engineering, and during general engineering side slope design, a side slope toe line is determined according to a junction structure, then the width, height and slope ratio of each grade of berm roads are designed according to the topographic and geological conditions of the side slope and the engineering operation requirements, and side slope support measures are made. When the terrain of a junction area is high and steep, or immovable important buildings or main roads and railways exist on a side slope, the side slope excavation is limited more, and only a strong supporting mode can be selected, so that the economy is poor.
The fishway is used as the most main fish passing facility in hydropower engineering, is generally arranged on a bank slope on one side of a hub and limited by fishway slope and upstream and downstream water head difference, usually needs to extend a long distance to upstream and downstream, generally adopts a bent frame type to climb on a side slope, and the arrangement mode has more construction period and site limitation conditions for fishway construction, increases side slope load in the fishway and is not stable and favorable for the side slope.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the fishway structure arrangement structure combined with the protection of the important bank slope building is provided, so that the fishway can be used for finishing the side slope excavation supporting construction combined with the protection of the important bank slope building in the construction preparation period and becomes a part of a side slope protection structure.
The utility model adopts the technical proposal that: a fishway structure arrangement structure combined with the protection of important buildings on bank slopes is characterized in that: the side slope toe is provided with a fishway structure, a fishway pool chamber is arranged on the main structure of the fishway structure, the main structure of the fishway structure is used as a side slope toe retaining wall, and stone slag is backfilled between the main structure of the fishway structure and the excavated side slope to reach the top elevation of the fishway, so that the weight of the side slope toe is increased.
The fishway structure is not built according to a slope, but a foundation is built in front of the slope and is built on the fishway structure, the disturbance to important protection objects on the slope is small, large-scale slope-releasing excavation and supporting on the slope are not needed, the main structure of the built fishway can be used as a bank slope toe retaining wall, a backfill area behind the fishway main structure can also be functionally utilized, and backfill stone slag can be rolled flatly to form a platform and then can be used as traffic in a field.
The major structure of the fishway structure is poured on the slope toe bedrock after the slope toe is temporarily excavated to the bedrock. The utility model discloses a fishway structure arrangement structure, when the basic overburden degree of depth is great, can adopt and pour the bored concrete pile conduct in the overburden the major structure's basis plays the toe of slope simultaneously and prevents the effect of washing.
The utility model discloses, when increasing the ballast bottom the side slope, keep upper portion side slope original state, fishway basis excavation side slope is interim side slope, all keeps original state topography more than the fishway elevation, does not carry out the construction.
The invention has the beneficial effects that: (1) the utility model discloses a fishway is as side slope protection engineering measure, the disturbance of important protection object on the side slope is little, need not to carry out extensive slope excavation and support to the side slope, only need carry out certain clear table excavation to the fishway basis, under the condition of the important building side slope original state of bank slope of keeping as far as possible, combine the fishway to realize the protection of the important building of bank slope that water and electricity engineering pivot district received the influence, carry out the ballast and protect it not by the river washing to the toe, greatly reduced important protection object causes the possibility of destruction because of the engineering construction. And (2) reducing the amount of the slope excavation supporting engineering. (3) Fishway and side slope protection can be completed before the main engineering works, so that construction interference is reduced, and the construction period is shortened. (4) The platform formed by backfilling and weighting the stone slag can be used as traffic in a field, and is convenient for overhauling a fishway in the operation period and the like.
Drawings
Fig. 1 is a schematic diagram of the embodiment of the fishway structure arrangement structure combined with the protection of the important buildings on the bank slope.
Wherein, A represents a protective object such as a railway, a highway or an important building, B represents an original ground, C represents a foundation boundary line, D represents an excavation line, and E represents a river bed.
Detailed Description
Reference is made to the accompanying drawings. A fishway structure arrangement structure that combines with important building protection of bank slope include fishway structure and backfill stone ballast 2, fishway structure includes fishway pond room 3 that sets up on major structure 1 and the major structure 1.
Before the main body engineering construction, the slope foot of the bank slope is temporarily excavated to bedrock or a concrete cast-in-place pile is constructed to form a fishway foundation, a fishway structure is poured on the fishway foundation, and the rear part of the main body structure 1 of the fishway structure is synchronously backfilled with stone slag 2 to form the slope presser foot. The backfill stone slag can be rolled and flattened to form a platform for traffic in a field.
The above description is not right the utility model discloses a restriction, the utility model discloses also not be limited to the above-mentioned example, the ordinary skilled person in this technical field the utility model discloses an within range, the change of making, add or replace, for example adjust fishway concrete and backfill structure or basic processing mode to reach and reduce the side slope and strut the processing engineering volume, reduce side slope protection and fishway structural style to the protection object disturbance, all should belong to the utility model discloses a protection scope.
