Description
Technical field
This utility model is related to river course bridge construction technical field, particularly relates to one kind and is used for river course abrupt slope basement rock
On Main Pier of Bridges cushion cap foundation ditch steel plate pilework.
Background technology
Constantly develop with China's economic society, the city rural volume of traffic is also increasing, strengthen road and bridge
Construction, can preferably meet the requirement of the development to transportation industry for the people, improve the quality of life of people, promote local
Economic development.
Apply man-hour requirement in Main Pier of Bridges cushion cap foundation ditch in the face of complicated geology, hydrology construction, difficulty of construction and requirement
Relatively higher.As steeper sandstone dirt bed riverbank in the gradient constructs brings difficulty to main pier bearing platform construction, and a part of position of cushion cap
On the abrupt slope basement rock on riverbank, another part gos deep into river or river, and side is navigation channel, and its bearing platform construction is necessarily in the face of the water surface
SEA LEVEL VARIATION and river immersion pressure, the side slope construction by navigation channel is unstable, faced by hydraulic pressure larger and pressure becomes
Change and there is uncertainty, a couple of days at least main pier bearing platform engineering time of bridge, the at most several months, as the boundary in flood season and non-flood period
Time, more should pay attention to its working security and quality, but in the construction of prior art, one is that prior art cost is very high
High, two is also undesirable to the effect of foundation ditch inner waterproofing, sealing, so needing one kind more preferably to build in river course abrupt slope base
The foundation pit supporting construction of the Main Pier of Bridges cushion cap on rock.
Content of the invention
In order to overcome the shortcomings of existing technology, this utility model provides the bridge on a kind of basement rock for river course abrupt slope
The steel plate pilework of main pier bearing platform foundation ditch.
Technical solutions of the utility model are as described below:
A kind of steel plate pilework of the Main Pier of Bridges cushion cap foundation ditch on basement rock for river course abrupt slope is it is characterised in that include
Steel sheet pile, the section of described steel sheet pile is in that " c " type constructs, and adjacent described steel sheet pile is relative two-by-two, and side is engaged each other
Connect, described steel sheet pile is on riverbed lithosphere, and described steel sheet pile runs through riverbed cobble cover layer and cofferdam is built island and banketed
Layer.
Further, described steel sheet pile is at 1 meter of described cofferdam Zhu Dao edge.
Further, between described steel sheet pile, junction is provided with rubber.
Further, connected overall structure is curved two-by-two for described steel sheet pile.
Further, described steel sheet pile builds island and the river course water surface higher than described cofferdam.
According to this utility model of such scheme, its advantage is, this utility model can be to Main Pier of Bridges cushion cap
The effective waterproof of foundation ditch, sealing, effectively overcome by the complicated geology in navigation channel side, hydrology construction and feature to Main Pier of Bridges cushion cap
The adverse effect of construction, solves river water level change, river pressure and river and immerses foundation ditch impact Main Pier of Bridges cushion cap
Construction problem, this utility model does not affect river course mid-channel and passes through, and structure is simple, easy to make, cost savings.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that in this utility model, pore cross section figure is drawn in twist bit cutting；
Fig. 3 is top view of the present utility model；
Fig. 4 is embodied as illustration for this utility model.
In in figure, 1, steel sheet pile；2nd, armored concrete arch ring；3rd, auger；4th, island fill stratum is built in cofferdam；5th, stake holes；6、
Riverbed cobble cover layer；7th, riverbed lithosphere；8th, Main Pier of Bridges；9th, urban river water.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment conducts further description to this utility model:
As Figure 1-4, the steel plate pilework of the Main Pier of Bridges cushion cap foundation ditch on a kind of basement rock for river course abrupt slope, including
Steel sheet pile 1, the section of steel sheet pile 1 is in that " c " type constructs, and adjacent steel sheet pile 1 is relative two-by-two, and side is connected each other,
Steel sheet pile 1 is on riverbed lithosphere 7, and steel sheet pile 1 runs through riverbed cobble cover layer 6 and island fill stratum 4 is built in cofferdam.
At 1 meter of cofferdam Zhu Dao edge, between steel sheet pile 1, junction is provided with rubber to steel sheet pile 1, prevents urban river water 9 from oozing
Enter, connected overall structure is curved two-by-two for steel sheet pile 1, Stability Analysis of Structures is conducive to buffering the surge of urban river water 9, steel sheet pile
Build island and urban river water 9 plane higher than cofferdam, prevent from during 9 flood season of urban river water, overflowing cofferdam and build island, impact bridge main pier bearing platform foundation ditch.
This utility model first at 1 meter of the cofferdam Zhu Dao edge by river course side with 3 quarter of auger stake holes 5, stake holes 5 continuously connects
Connect formation arc, then steel sheet pile inserting piling entered stake holes 5, adjacent steel sheet pile 1 is relative two-by-two, and side is connected each other,
Surround Main Pier of Bridges 8 cushion cap foundation ditch by river course side it is ensured that steel sheet pile 1 passes through riverbed cobble cover layer 6 and cofferdam to build island and fill out
Soil layer 4, arrives at riverbed lithosphere 7, is provided with armored concrete arch ring 2, steel sheet pile 1 and armored concrete arch ring inside steel sheet pile 1
2, mutual security Main Pier of Bridges cushion cap foundation ditch, waterproof, sealing.
This utility model can to Main Pier of Bridges cushion cap foundation ditch effective waterproof, sealing, effectively overcome multiple by navigation channel side
Miscellaneous geology, the hydrology construction and feature adverse effect to Main Pier of Bridges bearing platform construction, solve river water level change, river pressure
Power and river immerse foundation ditch and affect the construction problem of Main Pier of Bridges cushion cap, and this utility model does not affect river course mid-channel and leads to
OK, structure is simple, easy to make, cost savings
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
