Abstract

A method for leveling the bridge slabs in the maintenance of bridge includes installing a bridge maintaining unit with a supporting beam at the position on bridge to be maintained, putting the easily deforming containers on said supporting beam, pouring concrete in them, pushing up the supporting beam until the concrete is closed to the lower surfaces of bridge slabs, solidifying the concrete, and further pushing up the supporting beam to hold the upper surfaces of bridge in a same level.

Description

A kind of bridge board leveling method that is used for bridge maintenance

Technical field

The present invention relates to the maintenance field of bridge, particularly a kind of bridge board leveling method that is used for bridge maintenance.

Background technology

In the bridge construction process, in order to reduce bump and the vibration that vehicular load causes bridge, simultaneously also in order to satisfy the needs of bridge board different directions displacement, generally at the bent cap of bridge and shelve between the bridge board on it and be provided with bearing, wherein mostly be the rubber material, aging easily, the particularly inflow use of bearing inferior and the appearance of jerry-built project at a low price in recent years, the replacing of bridge maintenance and bearing has market greatly.Traditional method for maintaining is, sets up support from the road under bridge face, will change, keep in repair after the bridge board jack-up, therefore, needs road closure, envelope bridge when maintenance, influence traffic, and this method can't be used for the bridge of bridge pier post at the sea, river.For this reason, it is a kind of with the maintenance unit of bridge pier post as stressed bearing post that " method for maintaining of bridge pad and the device " that No. 00108445.3, my application for a patent for invention formerly provides, it includes anchor ear brake holding and following brake holding on the bridge pier post, and on, following brake holding connects by strut, form whole fixed mount, jack is set thereon, and by embracing fixedly a plate of holder, the many also whole up connecting rod groups that are the umbrella frame shape are set on junction plate again, the upper end of connecting rod group links to each other with joist under being positioned at bridge board, thereby forms the carriage of an integral body.During maintenance, only need jack is upwards pushed up, then joist will hold up bridge board, the bearing on the promptly replaceable bent cap.This patent application initiated with the bridge pier post make stressed bearing post, with joist with the whole method for maintaining that holds up of bridge board, work efficiency is improved greatly, while can construct, be open to traffic, do not influence traffic.But also there is a problem in this design scheme, the thickness that is each bridge board might not be identical, and after bridge construction was finished, the upper surface of each bridge board was equal, and the soffit of bridge board might be to be uneven, therefore, when joist holds up bridge board integral body, because the deadweight of bridge board, the soffit of each bridge board will be equal because of being pressed on the joist, so the upper surface of each bridge board then becomes and is uneven, thereby influence is open to traffic.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of bridge board leveling method that is used for bridge maintenance at above-mentioned prior art present situation, makes each bridge board because of maintenance during by joist jack-up, and it is equal that their upper surface still keeps.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: the bridge board leveling method in this bridge maintenance may further comprise the steps: 1. install the bridge maintenance device that has joist at bridge place to be keeped in repair; The quantity of 2. pressing bridge board is selected the easy deformation material container of respective numbers, in each container, behind the fluid concrete, their compartment of terrains placed on the joist, and relative with each bridge board; 3. utilize the last top function of maintenance unit self to push up on the joist, the concrete in each container all with behind the soffit pressurized of corresponding bridge board is close to, and keeps a period of time, and is dry and hard until concrete; 4. utilize the last top function of maintenance unit self that joist is up pushed up again, promptly still remained original phase level state by each bridge board upper surface of jack-up this moment.

" the bridge maintenance device that has joist " in above-mentioned can adopt as disclosed scheme in No. 00108445.3 application for a patent for invention, also can adopt other prior aries, so long as utilize joist with bridge board jack-up and keep in repair just can adopt the inventive method.

Compared with prior art, the present invention does solid method with the concrete scene dexterously between joist and bridge board, the soffit unification of original and irregular each bridge board is filled up smooth, thereby guarantee that the upper surface of each bridge board (being bridge floor) still keeps equal when joist flattens and does concrete block after consolidating in by container in advance and holds up each bridge board.

Description of drawings

Fig. 1 is the structural representation of the embodiment of the invention.

Structural representation when Fig. 2 all pastes with the soffit of corresponding bridge board mutually for the concrete in each container of back, top on the joist.

Fig. 3 is an application examples schematic diagram of the inventive method.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 3, the bridge board leveling method in the bridge maintenance may further comprise the steps:

1. install the bridge maintenance device that has joist at bridge place to be keeped in repair, adopt Z font carriage of linking up with on the bent cap of bridge 6 and the scheme (this scheme is applied for a patent separately) that jack 5 is set in the present embodiment thereon, referring to Fig. 3;

The quantity of 2. pressing bridge board is selected the easy deformation material container 1 of respective numbers, as iron sheet container, rubber and plastic container etc., in each container 1, behind the fluid concrete 3, their compartment of terrains placed on the joist 2, and relative with each bridge board 4, referring to Fig. 1;

3. utilize the last top function (in example shown in Figure 3 promptly by jack on push up) of maintenance unit self will be on the joist 2 top, concrete 3 in each container 1 all pastes mutually with the soffit of corresponding bridge board 4, keep a period of time, dry and hard until concrete 3, referring to Fig. 2;

4. the last top function (in example shown in Figure 3 promptly by jack on push up) of utilizing maintenance unit self is with joist 2 top up again, and promptly still remained original phase level state by each bridge board 4 upper surface of jack-up this moment.

Claims

1, the bridge board leveling method in a kind of bridge maintenance is characterized in that may further comprise the steps:

1. install the bridge maintenance device that has joist at bridge place to be keeped in repair;

The quantity of 2. pressing bridge board is selected the easy deformation material container of respective numbers, in each container, behind the fluid concrete, their compartment of terrains placed on the joist, and relative with each bridge board;

3. utilize the last top function of maintenance unit self to push up on the joist, the concrete in each container all pastes mutually with the soffit of corresponding bridge board, keeps a period of time, and is dry and hard until concrete;

4. utilize the last top function of maintenance unit self that joist is up pushed up again, promptly still remained original phase level state by each bridge board upper surface of jack-up this moment.
