Description
Technical Field
The application relates to the technical field of building bridges, in particular to a bridge head butt strap structure for hydraulic engineering.
Background
The bump at the bridge head refers to deformation, fracture and even pit of a road surface or a butt strap in the whole area of the connection between a road and a bridge abutment, so that the vehicle is obviously jumped and bumped after being impacted when running through the area, the bump at the bridge head is more and more commonly existed on all levels of roads along with the increasing of traffic flow, the bump of the vehicle caused by the bump phenomenon can not only cause discomfort of personnel in the vehicle, but also can cause the vehicle to be out of control, threaten the safety and seriously affect the road traffic safety, although the problem is solved by the majority of road practitioners from many aspects such as design to construction, the bump at the bridge head is not well solved all the time.
The bridge cover plate mould is also called as a bridge head butt strap and is used for preventing the settlement of the bridge end connecting part. It rests between the abutment or end of the cantilever and the fill and is able to rotate as the fill settles. The vehicle can play a role in buffering when running, and unevenness can not be generated even if the table back is filled with soil and settled.
A novel bridgehead butt strap structure for hydraulic engineering is provided.

By adopting the scheme, the sleeper beam degree is set to support the bridge head butt strap, the bridge head butt strap is prevented from being excessively sunk into the filled soil due to stress in the using process, and the rotating amplitude of the bridge head butt strap is reduced.
The application is further configured to: support columns driven into the filling soil are arranged below the sleeper beams, the support columns are uniformly arranged at intervals along the length direction of the sleeper beams, and the sleeper beams are supported on the support columns.
Through adopting above-mentioned scheme, it supports the sleeper beam to set up the support column, when the support column was being squeezed into in the banket, the banket of support column below is beaten tightly, and the lower extreme of support column supports on harder earth, and not support on soft banket, thereby make the support column be difficult for sinking, and is same, utilize the support column to support the sleeper beam, the sleeper beam is difficult for sinking, has reduced the rotation of bridgehead attachment strap, and make difficult production too big drop between bridgehead attachment strap and the road surface.
The application is further configured to: the bottom of the sleeper beam is provided with a jack, and the upper end of the supporting column is inserted into the jack and supports the sleeper beam.
Through adopting above-mentioned scheme, set up the jack in the bottom of sleeper beam to insert the upper end of support column in the jack, then squeeze into the support column in the filled soil and can carry on spacingly to the sleeper beam, avoid the position of sleeper beam to take place the skew and can't play the support to the bridge head attachment strap.
The application is further configured to: the upper surface of the sleeper beam also extends upwards to form an extension part, and one side surface of the bridge head butt strap back to the abutment is attached to and tightly abutted against the extension part.
Through adopting above-mentioned scheme, set up the extension on the sleeper beam, support the bridgehead attachment plate through the extension for the bridgehead attachment plate is difficult for removing to the one side that deviates from the abutment.
The application is further configured to: and a gravel cushion layer, a gravel surface layer and a concrete pavement are sequentially paved above the bridge head butt strap.
The application is further configured to: and asphalt mastic is filled in a gap between the bridge head butt plate and the abutment.
Through adopting above-mentioned scheme, at the fill pitch mastic between bridgehead attachment strap and abutment, avoid the direct striking abutment of bridgehead attachment strap to can play buffering and sealed effect.
The application is further configured to: the bridge head butt strap with between the bracket, the bridge head butt strap with between the sleeper beam, all cushion between bridge head butt strap and the filling soil and have hot felt.
Through adopting above-mentioned scheme, hot oil felt can play waterproof sealing's effect, avoids the rainwater to permeate the filling layer from the gap and leads to the filling to subside.
In summary, the present application has the following beneficial effects: effectively improving the bump at the bridge head caused by filling settlement.
