Description
Technical field
The present invention relates to a kind of grouting equipment, especially a kind of squeezing trolley, belong to equipment for bridge construction field.
Background technology
Pre-stressed bridge is very universal in bridge construction is constructed, and the grouting quality of the prestress pipe in pre-stressed bridge is one of mostly important factor determining bridge quality.The grouting quality reaching design requirement can make prestress wire play one's part to the full, there will be anchor head stress collection when there is grouting quality defect and neutralize the loss of prestress phenomenon elapsed in time, and the design stress of beam body can be changed, reduce the bearing capacity of bridge, and then affect service life of bridge, and bring use potential safety hazard.According to statistics, owing to mud jacking leakiness causes steel strand wires corrosion in prestress pipe, prestressing force is lost in advance, and bridge actual life can be caused to foreshorten to 1/10th of projected life.Therefore the grouting quality of prestress pipe is the critical process that bridge construction quality controls.
The grouting equipment of prestress pipe is mainly by squeezing trolley.Current squeezing trolley mainly includes a base being welded by hollow steel, base lower end is provided with the pulley of convenient slip, overlap on base for by the agitator tank of mud jacking raw material mix homogeneously and the slurry can of storage cement mortar, agitator tank lower end arranges one and leads the slurry pipe top towards slurry can.Slurry can lower end is provided with for providing output power mud jacking screw pump for cement mortar, connect on mud jacking screw pump and have grout pipe line, grout pipe line connects with one end of prestress pipe, and on grout pipe line, it is provided with the control valve that grout pipe line can be opened and closed, grout pipe line for will the cement transportation being stored in slurry can that be stirred in prestress pipe, the other end of prestress pipe connects pulp pipeline, the pulp pipeline other end is divided into two pipelines, article one, pipeline leads to slurry can, another pipeline leads to useless slurry cylinder, article two, pipeline is both provided with the control valve that can open and close.Meet design requirement in order to the cement mortar entered in prestress pipe is carried out real-time monitoring, pulp pipeline and grout pipe line are fitted with Pressure gauge and effusion meter.
The cement mortar quality of the prestress pipe in pre-stressed bridge is one of key factor determining bridge quality.Feeding is the source factor determining cement mortar quality, and therefore feeding is also the critical process that bridge construction quality controls.If opinion is artificial loading or machinery feeding, the order of feeding and the size of amount have strict requirements, reality to be that unfamiliar operator often cannot hold accurately, thus affect the quality of cement mortar.In existing squeezing trolley, agitator tank is the most all significantly larger than slurry can, when the press mortar in agitator tank all stir qualified after cement mortar can deadweight effect under along lead slurry pipe be flowed in slurry can storage.But higher agitator tank needs feeding personnel to bear heavy press mortar ascends a height and just can complete feeding operation, brings a lot of inconvenience to artificial loading.
Prior art is cannot normally to measure force value in pipeline owing to the medium in grout pipe line is that the most common Pressure gauge of cement mortar is directly installed on grout pipe line, manometric internal structure can be caused damage, also bring inconvenience to cleaning simultaneously；Grout pipe line and the pulp pipeline of generally installing effusion meter are all horizontal positioned, being arranged on pipeline of effusion meter level, in use, there is not the inaccurate problem of metering in cement mortar flow measurement when grout pipe line and pulp pipeline are filled with cement mortar, but when grouting procedure starts, in pipeline, cement mortar is according to by without to having again to full pipeline, when not being full of cement mortar in pipeline, effusion meter is not the most accurate to the metering of cement mortar flow, and cement mortar level pass through effusion meter, between cement mortar, space is bigger, loosely, metering for flow also can produce error；Squeezing trolley is required for being rinsed program in time after use completes simultaneously, especially it is easier to shelter evil people and countenance evil practices with grout pipe line and pulp line connection at effusion meter, these joints simultaneously local cleans also tend to not have smooth pipeline to clear up clean, in the course of time the cement slurry sets of joint and more and more, the flow measurement of cement mortar can be more and more inaccurate.Therefore in practical work process, the mounting means of Pressure gauge and effusion meter all can affect the quality of pre-stressed bridge.
