Description
Technical field
The cofferdam technical field of hydraulic engineering or science of bridge building is the utility model is related to, more particularly to a kind of steel sheet pile encloses
Weir.
Background technology
In hydraulic engineering or science of bridge building, it is often necessary to carry out cofferdam construction, common cofferdam type have earth cofferdam,
Earth-bag cofferdam, steel sheet-pile cofferdam and double-wall cofferdam, wherein steel sheet-pile cofferdam are a kind of the most frequently used sheet-pile cofferdams.Steel sheet pile is band
There is a kind of shaped steel of fore shaft, there are straight panel shape, flute profile and Z-shaped etc. in its section, there is full range of sizes and interlocking form.It common are
Ademilson formula of drawing, clarke Wan Nashi etc..The advantages of steel sheet-pile cofferdam is intensity height, easily squeezes into hard soil layer；It can be applied in deep water
Work, if necessary plus bearing diagonal turns into an inclosure.Water resistance is good；The cofferdam of various profiles can be formed on demand, and can be multiple
Reuse, therefore, it widely used.Before injection steel sheet pile, measurement observation station should be set in cofferdam upstream and downstream and two sides, controlled
The injection positioning of the long and short edge direction in cofferdam.Steel sheet pile can be sunk with the methods of knocking, vibration, jetting, but should not be used in clay
Jetting sinking method.During steel sheet pile injection, it is necessary to when check stake whether position correct, whether pile body vertical, otherwise
It should correct or extract immediately and beat again.This just proposes higher requirement, and this steel sheet pile to the construction technology of workmen
The method of construction also extends the duration.
Utility model content

Strut, interior leading truck and support beam group improve the stability of leading truck into an A-frame.
, so can be with least provided with a bearing diagonal between adjacent steel sheet pile in order to improve the intensity of steel cofferdam
Keep out the impact of current.
Further, the first bearing diagonal, the second bearing diagonal and the 3rd bearing diagonal are provided between adjacent steel sheet pile, it is described
Second bearing diagonal and the 3rd bearing diagonal are arranged on the first bearing diagonal and diameter is less than the first bearing diagonal.It is arranged such, not only
The impact resistance of steel sheet-pile cofferdam can further be strengthened, can also save material, because with the depth shallower of dampening, pressure also becomes
It is small.
Further, show that first bearing diagonal is by force analysisPile tube, described second tiltedly branch
Support and the 3rd bearing diagonal arePile tube when can take into account the requirement of cost and performance.
In order to increase ability of the resistance to water impact in the steel plate relative direction of steel sheet-pile cofferdam, in relative steel sheet pile
Between at least provided with a horizontal support.
Further, the first horizontal support, the second horizontal support and the 3rd horizontal support are provided between relative steel sheet pile, it is described
Second horizontal support and the 3rd horizontal support are arranged on the first horizontal support and thickness is less than the first horizontal support.It is arranged such, not only
Impact resistance of the steel sheet-pile cofferdam in the relative direction of steel sheet pile can further be strengthened, can also save material, because with dampening
Depth shallower, pressure also diminishes.
Further, first horizontal support is at least 3.9 meters apart from the distance of cushion cap, and this is in order to which workmen is easy to
Constructing operation is carried out in cofferdam.
Further, first horizontal support is the shaped steel of H600 × 200, and second horizontal support and the 3rd horizontal support are
The shaped steel of H400 × 200, this is to take into account performance and cost, by the data being calculated.
Compared with prior art, beneficial effects of the present invention：
1. the setting of leading truck, can convenient construction personnel steel sheet pile inserting piling is entered to the position specified exactly, improve and insert
Beat efficiency.
2. the setting of bearing diagonal and horizontal support, the impact capacity of steel sheet-pile cofferdam resistance current can be strengthened.
3. the diameter or variable thickness sample of bearing diagonal and horizontal support, can be cost-effective on the premise of performance is ensured.
