Abstract
The utility model discloses a layout structure of a high-water head multi-functional dam on a deep soft foundation. The layout structure comprises a dam body. The dam body is of a lock chamber structure. An open type overflow dam and a gravity dam are arranged in a vertical flow on a lock chamber base plate. Downstream flow length of a lock chamber base plate on an upstream side of the open type overflow dam and the gravity dam is larger than the overall downstream flow length of the integral lock chamber base plate by 2/5-1/2. A downstream section of an open type overflow dam weir surface is connected with an energy dissipation facility through an ogee section. A draining and desilting bottom hole and a power generation aqueduct are arranged from the upstream side to the downstream side in the gravity dam. A downstream section of the draining and desilting bottom hole is connected with the energy dissipation facility. A downstream section of the power generation aqueduct is communicated with a water turbine behind the dam. The layout structure has the advantages that discharging capacity of the open type overflow dam is fully utilized; by the draining and desilting bottom hole, requirements of discharging a reservoir, desilting and generating power with clear water are met; thus safety of the dam body that is of the lock chamber structure and comprehensive development tacks are guaranteed.
Description
Technical field
The utility model relates to the multi-functional dam of deep soft foundation high water head, especially relates to the arrangement on the multi-functional dam of deep soft foundation high water head.
Background technology
On deep soft foundation, build high water head hydraulic structure, the subject matter of existence is that Lack of support and sedimentation and deformation are excessive, thereby affects engineering safety.Therefore, on deep soft foundation, build a dam while highly exceeding 30m and conventionally to adopt earth and rockfill dam dam type, and at bank correct position, flood spillway is set separately and ensures enough flood carrying capacities.In the case of at present suitable landform of building flood spillway and geological conditions reduce day by day, in the urgent need to meeting under deep soft foundation high water head condition, the comprehensive dam type body that the several functions such as dash, sluicing, generating, flood control can be integrated in one.
Summary of the invention
The utility model object is to provide the arrangement on the multi-functional dam of a kind of deep soft foundation high water head.
For achieving the above object, the utility model is taked following technical proposals:
The arrangement on the multi-functional dam of deep soft foundation high water head described in the utility model, comprises the dam body being arranged on riverbed, described dam body both sides respectively by quaywall be arranged in described riverbed two earth and rockfill dam on the bank and be connected; Described dam body is lock chamber structure, and described lock floor basis is drill-pouring pilework, on lock floor, is furnished with open type overfall dam and gravity dam along Transverse to the flow direction; The lock floor that is positioned at described open type overfall dam, gravity dam upstream side flows the 2/5-1/2 that length is greater than lock floor and flows downstream entire length downstream; On the lock floor of described open type overfall dam, both sides, gravity dam upstream, be furnished with respectively abutment pier along Parallel to the flow direction; Described open type weir crest face downstream is connected with energy-dissipating installation by anti-segmental arc; In described gravity dam body, be provided with sluicing bottom hole for sand flushing and generating aqueduct from upstream side to downstream; Described sluicing bottom hole for sand flushing downstream is connected with energy-dissipating installation, and described generating aqueduct downstream is communicated with the hydraulic turbine behind dam.
Be positioned at described dam body upstream and be furnished with respectively aileron and bedding.
The utility model advantage is mainly reflected in following several respects:
1, the dam body both sides of described lock chamber structure are connected with the earth and rockfill dam that is arranged in two sides, riverbed by quaywall respectively, while not only ensureing flood discharge, current are smooth and easy, open excavation amount is few, and take full advantage of the super ability of letting out of open type overfall dam, described sluicing bottom hole for sand flushing can meet reservoir emptying, sand discharge and clear water generating requirement simultaneously, thereby has ensured the safety of lock chamber structure dam body and the realization of comprehensive development task.
2, described dam body adopts sluice structure build, by being arranged in the gravity dam dash on described lock floor, make full use of the water that is positioned at open type overfall dam, gravity dam upstream side lock floor top and heavily meet integral dam stability requirement, reach and significantly save concrete work amount object.
3, by adjusting described gravity dam fundamental triangle position of centre of gravity, reach and meet dam body runtime bearing capacity of foundation soil and differential settlement requirement; Meanwhile, the abutment pier being arranged on open type overfall dam, both sides, gravity dam upstream lock floor along Parallel to the flow direction can be introduced lock chamber by water flow stationary, and sluicing and sand discharge are interference-free, have guaranteed sand discharge effect.
4, described lock floor arranges ater-casting in the construction period, bears construction period dam body vertical load by being arranged in the bored pile on described lock floor basis, reaches and meets dam construction phase bearing capacity of foundation soil and differential settlement requirement; Significantly save Grouting Pile Engineering of Drilling Hole amount simultaneously.
