Abstract
The invention discloses a novel bridge pier construction process and relates to the field of building construction. The novel bridge pier construction process comprises the following steps: paving a bridge pier base platform, binding a pier body steel bar framework, assembling templates, pouring the pier body and pouring a top cover. An X-shaped pier body is arranged at the top of the base platform of the novel bridge pier; an X-shaped steel bar framework is arranged in the pier body; a rectangular plate-shaped top cover is arranged at the top of the pier body; the pier body, the base platform and the top cover form an upper triangle and a lower triangle; the bearing capacity of the bridge pier is improved by making full use of the stability of the triangles; the overall stability of a bridge is improved.
Description
Technical field
The present invention relates to the realm of building construction, particularly to a kind of new-type bridge pier construction technology.
Background technology
Two across with two in above bridge except the abutment that two ends are connected with embankment remaining medial support structures be called that bridge pier, bridge pier are built in the solid ground place of below bed-silt.Existing traditional bridge pier structure is mostly in simple cylindricality, and weight capacity is general, it is impossible to meet the requirement for the high load-bearing of bridge pier of the modern bridge.
Summary of the invention
The technical problem to be solved is to provide a kind of new-type bridge pier construction technology, by designing the pier shaft of X-shaped, and arranges the framework of steel reinforcement of X-shaped inside pier shaft, improves the weight capacity of bridge pier.
For achieving the above object, the present invention provides following technical scheme: a kind of new-type bridge pier construction technology, it is characterized in that: described new-type bridge pier construction technology includes the base station of rectangular plate-like, base station top is provided with the pier shaft of X-shaped, the framework of steel reinforcement of X-shaped it is provided with inside pier shaft, pier shaft top is provided with the top cap of rectangular plate-like, and the step of this new-type bridge pier construction technology is as follows:
(1) bridge pier base station is laid: use cement mortar to lay base station on bridge foundation, and on base station, lay Steel-bar Pile；
(2) colligation pier shaft framework of steel reinforcement: utilize the Steel-bar Pile on base station, uses screw-thread steel framework of steel reinforcement of colligation X-shaped above base station；
(3) rigging: use the template setting up X-shaped outside lifting machine framework of steel reinforcement above base station；
(4) pier shaft is built: use concrete casting machine to water in template and erect X-shaped pier shaft；
(5) top cap is built: use concrete casting machine to build the head of a nail of rectangular plate-like at pier shaft top.
Preferably, the screw-thread steel colligation that described framework of steel reinforcement adopts the trade mark to be 20MnSiV forms.
Adopting above technical scheme to provide the benefit that: the base station top of this new-type bridge pier is provided with the pier shaft of X-shaped, be provided with the framework of steel reinforcement of X-shaped inside pier shaft, pier shaft top is provided with the top cap of rectangular plate-like.Pier shaft and base station, top cap form upper and lower two trianglees, and the steadiness taking full advantage of triangle adds the weight capacity of this bridge pier, improve the steadiness that bridge is overall.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is the front view of a kind of new-type bridge pier construction technology of the present invention；
Fig. 2 is the sectional view of a kind of new-type bridge pier construction technology of the present invention；
Fig. 3 is the flow chart of a kind of new-type bridge pier construction technology of the present invention.
Wherein, 1-pier shaft, 2-top cap, 3-base station, 4-framework of steel reinforcement.
Detailed description of the invention
The preferred implementation of a kind of new-type bridge pier construction technology of the present invention is described below in conjunction with accompanying drawing.
The detailed description of the invention of a kind of new-type bridge pier construction technology of the present invention is shown: this new-type bridge pier construction technology includes the base station 3 of rectangular plate-like in conjunction with Fig. 1, Fig. 2 and Fig. 3, base station 3 top is provided with the pier shaft 1 of X-shaped, the internal framework of steel reinforcement 4 being provided with X-shaped of pier shaft 1, pier shaft 1 top is provided with the top cap 2 of rectangular plate-like.
As it is shown on figure 3, the step of this new-type bridge pier construction technology is as follows:
(1) bridge pier base station 3 is laid: use cement mortar to lay base station 3 on bridge foundation, and on base station 3, lay Steel-bar Pile；
(2) colligation pier shaft framework of steel reinforcement: utilize the Steel-bar Pile on base station 3, uses the framework of steel reinforcement 4 of screw-thread steel colligation X-shaped above base station 3；
(3) rigging: use the template setting up X-shaped outside lifting machine framework of steel reinforcement 4 above base station 3；
(4) pier shaft 1 is built: use concrete casting machine to water in template and erect X-shaped pier shaft 1；
(5) top cap 2 is built: use concrete casting machine to build the head of a nail 2 of rectangular plate-like at pier shaft 1 top.
In conjunction with Fig. 1 and Fig. 2, the screw-thread steel colligation that framework of steel reinforcement 4 adopts the trade mark to be 20MnSiV forms.
Pier shaft 1 and base station 3, top cap 2 form upper and lower two trianglees, and the steadiness taking full advantage of triangle adds the weight capacity of this bridge pier, improve the steadiness that bridge is overall.
Above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.
