This hydraulic engineering's strenghthened type cofferdam, through the outer loop, mutually support between stainless steel head and the stainless steel section of thick bamboo, reach and increase the fastness after the stainless steel head inserts on the riverbed at the inside filling silt of stainless steel section of thick bamboo, adopt the annular to lay the cofferdam simultaneously, make the cofferdam that compares traditional in bank setting block the dynamics stronger, be difficult for pulling out from the riverbed, it is in bank of nails that adopt the stake in bank that the cofferdam of having solved present hydraulic engineering is more in the riverbed, then pile department stacks article such as stone and form a cofferdam, the problem of rupture appears firmly inadequately and easily in this cofferdam.
Description
Technical Field
The utility model relates to a hydraulic engineering technical field specifically is a hydraulic engineering's strenghthened type cofferdam.
Background
The cofferdam is a temporary enclosure structure constructed for constructing permanent water conservancy facilities in the water conservancy project construction. The cofferdam has the functions of preventing water and soil from entering the building position of the building so as to drain water in the cofferdam, excavate a foundation pit and build the building. The cofferdam is mainly used in hydraulic engineering, except for being used as a part of a formal building, the cofferdam is generally dismantled after being used up, the height of the cofferdam is higher than the highest water level which can appear in the construction period, most of the prior cofferdams of hydraulic engineering adopt wooden piles which are nailed in rows on a riverbed, then stones and other objects are stacked at the wooden piles to form a cofferdam, and the cofferdam is not firm enough and is easy to break, so that the reinforced cofferdam needs to be provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hydraulic engineering's strenghthened type cofferdam, what has solved present hydraulic engineering's cofferdam is more adopts the nail in bank of stake at the riverbed, then stacks article such as stone in stake department and form a cofferdam, and this cofferdam is firm enough and the problem of breaking appears easily.
Technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a hydraulic engineering's strenghthened type cofferdam, includes the outer loop, the inner wall overlap joint of outer loop has a stainless steel section of thick bamboo, the bottom fixedly connected with stainless steel head of a stainless steel section of thick bamboo, the top overlap joint of a stainless steel section of thick bamboo has the holding ring, the lower fixed surface of holding ring is connected with the sealing plug, the surface of sealing plug and the inside joint of a stainless steel section of thick bamboo.
Furthermore, the stainless steel cylinder is filled with silt.
Furthermore, the inner wall of the outer ring is provided with a positioning groove, and a positioning block is clamped inside the positioning groove.
Furthermore, the right side of the positioning block is fixedly connected with the surface of the stainless steel cylinder.
Furthermore, the positioning block is fixedly connected with the outer ring through a fixing pin.
The utility model provides a hydraulic engineering's strenghthened type cofferdam. The method has the following beneficial effects:
1. this hydraulic engineering's strenghthened type cofferdam, through the outer loop, mutually support between stainless steel head and the stainless steel section of thick bamboo, reach and increase the fastness after the stainless steel head inserts on the riverbed at the inside filling silt of stainless steel section of thick bamboo, adopt the annular to lay the cofferdam simultaneously, make the cofferdam that compares traditional in bank setting block the dynamics stronger, be difficult for pulling out from the riverbed, it is in bank of nails that adopt the stake in bank that the cofferdam of having solved present hydraulic engineering is more in the riverbed, then pile department stacks article such as stone and form a cofferdam, the problem of rupture appears firmly inadequately and easily in this cofferdam.
2. This hydraulic engineering's strenghthened type cofferdam through the cooperation of constant head tank, locating piece and locating pin, reaches and to demolish and install every stainless steel section of thick bamboo for it is more convenient during the transportation cofferdam, through the cooperation of holding ring and sealing plug, reaches and consolidates between each stainless steel section of thick bamboo, avoids the stainless steel section of thick bamboo to scatter, avoids the river to wash out the inside silt of stainless steel section of thick bamboo simultaneously.
