Description

Bridge structure arrangement form utilizing sluice piers of river sluice on uneven geological layer

Technical Field

The utility model relates to bridge design technical field, more specifically is an utilize bridge structures arrangement form of river sluice gate mound on inhomogeneous geological stratification.

Background

Geological heterogeneity easily causes the uneven settlement of ground, and the uneven settlement of ground can cause the building above that to produce great additional stress, consequently for avoiding uneven settlement to produce too big stress, the river sluice structure of arranging on uneven geological formation generally can divide into a lot of structure sections along the river is horizontal, sets up the subsiding crack between structure section and the structure section.

The river sluice is provided with gate piers which transversely divide river water into a plurality of overflowing holes, and the vertical settlement difference between all sections is large and often exceeds the limit value specified by the specification of the uneven settlement difference between bridge piers of the bridge structure, so that the bridge structure is dare not to directly utilize the gate piers, and only suitable bridge positions are often found at the upstream or the downstream of the river sluice to arrange the bridge structure.

Additionally arranging a bridge structure requires additionally arranging a large number of piers and foundations, so that the manufacturing cost is greatly increased, a river-passing building is additionally arranged on a river to influence the ecology of the river, the river bed surface is damaged in the construction process, and the pollution to the river is increased.

Therefore, a structure for solving the above problems is urgently needed.

Disclosure of Invention

An object of the utility model is to overcome the weak point of above-mentioned background art, and provide a bridge construction arrangement form that utilizes sluice gate mound on the inhomogeneous geological stratification.

The utility model aims at being implemented through the following technical scheme: a bridge structure arrangement form utilizing river sluice piers on uneven geological layers is arranged on each section of river sluice upper sluice pier and comprises bridge piers, hollow slabs, wet joints, a concrete cast-in-place leveling layer and a bridge deck pavement;

every section the river sluice gate mound on pour the pier, the pier on be provided with the hollow core slab that a plurality of arranged side by side, a plurality of the hollow core slab between be provided with wet seam, the hollow core slab with wet seam on pour and have the cast-in-place levelling layer of concrete, the cast-in-place levelling layer of concrete on be provided with the bridge deck pavement.

In the above technical scheme: each section of the river sluice gate pier and the pier are connected into a whole in a pouring mode.

In the above technical scheme: the hollow slab adopts a simple supporting structure.

In the above technical scheme: the hollow slab and the wet joint are connected into a whole, and the cast-in-place concrete leveling layer arranged above the hollow slab is poured and positioned on the same high layer.

The utility model has the advantages of as follows: 1. the existing gate pier structure of the river sluice is used as a part of the pier structure, so that the cost for additionally arranging piers and foundations on the bridge structure is greatly saved. 2. The utility model discloses avoided construction pier and foundation construction once more to the ecological pollution of river and avoided the riverbed once more because of the advantage of the destruction that construction pier basis caused, avoided looking for the bridge position in addition simultaneously, reduced the building of crossing a river one, reduced the influence to the river flow state.

Drawings

Fig. 1 is a schematic view of the overall arrangement of the present invention.

Fig. 2 is a big picture of the middle pier and the sluice gate pier of the river sluice gate of the present invention.

Fig. 3 is a schematic structural diagram of the present invention.

In the figure: the bridge comprises piers 1, hollow slabs 2, wet joints 3, a concrete cast-in-place leveling layer 4, bridge deck pavement 5 and river sluice gate piers 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, 2 and 3: a bridge structure arrangement form utilizing river sluice gate piers on uneven geological layers is arranged on each section of river sluice gate pier 6 and comprises piers 1, hollow plates 2, wet joints 3, a concrete cast-in-place leveling layer 4 and a bridge deck pavement 5;

every section block floodgate mound 6 on pour gate mound 1, gate mound 1 on be provided with the hollow core slab 2 that a plurality of arranged side by side, a plurality of hollow core slab 2 between be provided with wet seam 3, hollow core slab 2 with wet seam 3 on pour and have concrete cast-in-place leveling layer 4, concrete cast-in-place leveling layer 4 on be provided with the bridge deck pavement 5.

And each section of the river sluice gate pier 6 is integrally cast with the pier 1. The river sluice gate pier 6 and the pier 1 are poured into a whole to be used as a pier of the supporting beam body, so that the bridge beam body directly utilizes the gate pier as a lower structure foundation, the pier foundation does not need to be rearranged, the gate pier 6 is effectively utilized, and the pier foundation engineering quantity is saved.

The hollow slab 2 adopts a simple supporting structure. The hollow slab that simple structure preparation formed when the both ends beam-ends takes place inhomogeneous settlement, can not produce additional internal force, can not cause the influence to the structural security.

The hollow slab 2 and the wet joint 3 are connected into a whole, and the cast-in-place concrete leveling layer 4 arranged above the hollow slab is poured and positioned on the same high layer. The hollow plates 2 are connected into a whole by the wet joint 3, the structural integrity is increased, and the whole structure can be coordinately deformed and stressed together. The leveling layer 4 can be leveled by the concrete cast-in-place leveling layer due to the height difference generated by the uneven settlement of the lower structure.

Referring to fig. 1, 2 and 3: the utility model discloses a following concrete construction steps: firstly, placing a prefabricated hollow slab 2 on a pier 1 in advance, then loading a weight on the erected hollow slab 2, and simultaneously monitoring the settlement condition of the pier 1 in real time;

secondly, when the settlement of the pier 1 is basically stable, pouring wet joints 3 between the hollow plates 2, connecting the hollow plates 2 and the wet joints 3 into a whole, then pouring a concrete cast-in-place leveling layer 4 above the whole of the hollow plates 2 and the wet joints 3, after the concrete cast-in-place leveling layer 4 is leveled, constructing bridge deck structures such as bridge deck pavement 5 and the like above the concrete cast-in-place leveling layer 4, and after the check is finished, enabling the pier to be ready to go on.

The above-mentioned parts not described in detail are prior art.
