City also builds bus rapid transit in succession, and in order to guarantee pedestrian's street crossing safety and public transport operation speed, matched overline bridge or mistake
Channel is just essential under street.Because construction section is mostly the heavy section of traffic, be not suitable for the open-cut of close traffic, so
It generally selects and uses prefabricated box culvert, then the mode of jacking construction.And during such section jacking construction, guarantee jacking side
To becoming in order to must solve the problems, such as.
Utility model content
The utility model provides a kind of box culvert jacking construction support device, by support plate surface setting limit
Slot and guide chute improve the controllability in jacking direction.
To achieve the above object, the utility model uses the following technical solution：
A kind of box culvert jacking construction support device, including support plate, the two opposite long lateral edge jackings of upper end face of support plate
Direction is provided with limiting slot, and the both ends port of limiting slot is located on two opposite short side end faces of support plate, two limiting slots it
Between support plate on be provided with the multiple guide chutes parallel with the limiting slot；It is very heavy that one end of support plate is equipped with receiving support
The supporting section on top, supporting section are equipped with rear back beam far from one end of support plate, and the support plate, supporting section and rear back beam are integrated into
Type.
Compared with the prior art, the utility model has the advantages that：
The guide chute of the receiving top pillar of support plate surface setting plays the role of limit to top pillar, guarantees that top pillar is same
Axis, makes box culvert uniform force, and direction is controllable；And such mode also reduces the contact area of support plate and box culvert, certain journey
Frictional resistance is reduced on degree；The limiting slot of support plate two sides setting not only plays the role of cross spacing to box culvert, also gives
Box culvert has reserved the space of prefabricated drainage ditch, reduces the difficulty of construction in underpass later period.
The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through
Research and practice of the invention are understood by the person skilled in the art.

Specific embodiment
In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to
Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：
Combined with Figure 1 and Figure 2, the utility model proposes a kind of box culvert jacking construction support device, including support plate 1,
The two opposite long lateral edge jacking directions in 1 upper surface of support plate are provided with limiting slot 3, and the both ends port of limiting slot 3 is located at support
On two opposite short side end faces of plate 1, it is provided in the support plate 1 between two limiting slots 3 parallel with the limiting slot 3 multiple
Guide chute 4；One end of support plate 1 is equipped with the supporting section 6 for accommodating support jack, and supporting section 6 is set far from one end of support plate 1
There is rear back beam 2, the support plate 1, supporting section 6 and rear back beam 2 are integrally formed.
In use, first carrying out necessary reinforcing to construction road surface, working pit then is excavated in road surface side, uses reinforced concrete
Soil pours the utility model box culvert jacking construction support device.In jacking construction, the one end jack A is supported in rear back beam 2,
The other end of jack A discontinuously exerts a force to box culvert C, and excavator is arranged inside box culvert C, opens simultaneously with the progress that jacking works
It digs, then with the progress that jacking works, top pillar B is added into guide chute 4, make a reservation under construction road surface until box culvert C reaches
Position.
The guide chute 4 of the receiving top pillar B of 1 surface of support plate setting plays the role of limit to top pillar B, guarantees top pillar
