Abstract
The invention provides a construction method for a frame bridge main body adjacent to existing buildings. The method comprises the following steps of determining a contour line of the frame bridge main body between the existing buildings without considering the operation side of construction personnel; determining the position of a protection pile at the external side edge part of the contour line of the frame bridge main body; finishing constructions of the protection pile and a crown beam; carrying out excavation operation of a foundation pit on the internal side of the protection pile; mounting a circle of extrude plastic board on the internal side of the protection pile as an external side template; and carrying out mounting of an internal side template, banding of reinforcing bars and pouring of concrete so as to finish the construction of the whole frame bridge main body. The construction method for the frame bridge main body adjacent to the existing building, provided by the invention, is advantaged in that the distances between the foundation pit and the existing buildings are increased; and the safeties of the existing buildings are preferably protected on the basis of finishing the protection of the foundation pit. As the extrude plastic board is mounted on the internal side of the protection pile as the external side template of a frame bridge, the construction effect of the method has no difference from that of the traditional template. As the area of the foundation pit is reduced, the earth excavation volume and filling volume are reduced, the disturbance to subsurface soil is reduced and the land is preferably protected while the construction cost is reduced.
Description
Technical field
The invention belongs to brick or concrete duct field, particularly relate to a kind of frame bridge main body construction method of being close to existing building.
Background technology
Along with the develop rapidly of infrastructure construction, the recoverable amount of automobile increases year by year, so batchs of city intersection work items is carried out successively, meanwhile, the difficult problem run in construction also gets more and more, and wherein needs the planning road passed through in the middle of two existing buildings also occurring successively.The protection will faced existing building during construction in this case, needs the ability relying on planning and designing department on the one hand, the road of design is avoided existing structure as best one can; Need on the other hand to rely on the construction ability of unit in charge of construction to protect existing structure.But construction effect is often not ideal, especially easily cause being discontented with of neighbouring resident.If the frame bridge on planning road is just between existing building, as Fig. 1, shown in Fig. 2, construction method conventional is at present original position excavation pit method, first the method determines the position of fender pile 2 between existing building 1 according to the needs of constructor's scope of operation, then the construction of a circle fender pile 2 and Guan Liang is completed, the excavation operation of foundation ditch 3 is carried out afterwards inside fender pile 2, finally complete template support, reinforcing bar binding, the construction of concreting, operation is carried out traditionally in this stage on the work plane giving constructor's indwelling, template adopts steel form or wooden form, and then complete the construction of whole frame bridge 4 main body.Wherein be faced with the perturbed problem to existing building 1 basis when fender pile 2 and Guan Liang construction, during foundation ditch 3 excavation construction, then may cause damage to existing building 1.But there is no good measure at present to control these problems.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of frame bridge main body construction method of being close to existing building.
In order to achieve the above object, the frame bridge main body construction method of contiguous existing building provided by the invention comprises the following step carried out in order:
1) carrying out surveying setting-out work according to frame bridge design drawing, between existing building, determining the outline line of frame bridge main body when not considering constructor's scope of operation;
2) position of fender pile is determined at frame bridge body profile line outer ledge position;
3) a circle fender pile and Guan Liang construction is completed;
4) the excavation operation of foundation ditch is carried out in the inner side of fender pile;
5), after excavation of foundation pit completes, a circle extruded sheet is installed as outboard template in the inner side of fender pile;
6) carry out the construction of inner side template installation, reinforcing bar binding, concreting, and then complete the construction of whole frame bridge main body.
Described inner side template adopts steel form or wooden form.
The frame bridge main body construction method of contiguous existing building provided by the invention has following beneficial effect:
(1) this method increases the distance of foundation ditch and existing building, and the basis completing foundation ditch protection protects the safety of existing building well.
(2) extruded sheet is installed inside fender pile as frame bridge outboard template, construction effect and conventional template indifference.
(3) reducing due to foundation ditch area, decreases soil excavation and backfill consumption, decreases the disturbance to underground soil, while reduction construction cost, protect soil better.
(4) reducing due to foundation ditch area, decreases the reinforcing bar of fender pile and Guan Liang, concrete amount, reduces construction cost, and economic benefit is given prominence to.
(5) eliminate the work of the departments such as planning and designing, while guarantee building safety, reduce cost, Social benefit and economic benefit is given prominence to.

Detailed description of the invention
Be described in detail below in conjunction with the frame bridge main body construction method of the drawings and specific embodiments to contiguous existing building provided by the invention.The parts identical with prior art adopt identical drawing reference numeral.
As shown in Figure 3, Figure 4, the frame bridge main body construction method of contiguous existing building provided by the invention comprises the following step carried out in order:
1) carrying out surveying setting-out work according to frame bridge design drawing, between existing building 1, determining the outline line of frame bridge main body 4 when not considering constructor's scope of operation;
2) position of fender pile 2 is determined at frame bridge main body 4 outline line outer ledge position;
3) a circle fender pile 2 and Guan Liang construction is completed;
4) the excavation operation of foundation ditch 5 is carried out in the inner side of fender pile 2, because foundation ditch 5 is distant compared with existing building 1, therefore, it is possible to reduce the disturbance to existing building 1 basis;
5), after foundation ditch 5 has excavated, a circle extruded sheet 6 is installed as outboard template in the inner side of fender pile 2;
6) carry out the construction of inner side template installation, reinforcing bar binding, concreting, and then complete the construction of whole frame bridge main body 4.
Described inner side template adopts steel form or wooden form.
Claims (2)
1. be close to a frame bridge main body construction method for existing building, it is characterized in that: the frame bridge main body construction method of described contiguous existing building comprises the following step carried out in order:
1) carrying out surveying setting-out work according to frame bridge design drawing, between existing building (1), determining the outline line of frame bridge main body (4) when not considering constructor's scope of operation;
