Pretreatment equipment for steel bridge deck pavement

Abstract

The invention discloses a pre-processing equipment for steel bridge deck paving, which relates to the technical field of infrastructure for bridge engineering, and comprises a frame, a base, a cleaning mechanism and a dust-absorbing mechanism. , the jet device is connected with a vortex tube through the air inlet pipe, the interior of the base is provided with a chamber 1 and a chamber 2, the base is installed on the inner bottom wall of the frame, and the lower end of the frame is also installed with Two symmetrically arranged power rollers are provided with scrapers parallel to the sides of the power rollers. The invention ensures that the bridge deck can be completely cleaned in the cracks before paving by arranging the cleaning mechanism in the base; the dust blown out from the cracks spreads to both sides along the axis direction of the power roller under the frame. A vacuuming mechanism is installed on the rack, and the dust is collected by the vacuum head and the vacuum pump into the corresponding collection box, so as to realize the automatic collection of dust and other sundries, and prevent the dust from being deposited into the surrounding cracks again.

Description

technical field [0001] The invention relates to the technical field of infrastructure for bridge engineering, in particular to a pretreatment device for steel bridge deck pavement. Background technique [0002] After cracks appear on the steel bridge deck, it needs to be repaired in time to prevent the cracks from continuing to expand. Usually, the way of sealing and potting is used for paving. For the dust inside the crack and the stubborn accumulation inside, the prior art usually uses a high-pressure air pump to blow from the initial section to the end section on one side of the crack. [0003] During the long-term repair of bridge deck pavement, our company found that there are still some deficiencies in the existing technology: 1. The high-pressure air pump can only blow out the dust attached to the inner surface of the crack and the dust deposited at the bottom, but for some stubborn attachments. It is not easy to blow out effectively, and because the cracks are not a...

Problems solved by technology

[0003] During the long-term repair of bridge deck pavement, our company found that there are still some deficiencies in the existing technology: 1. The high-pressure air pump can only blow out the dust attached to the inner surface of the crack and the dust deposited at the bottom, but for some stubborn attachments. It is not easy to blow out effectively, and because the cracks are not all vertical cracks or oblique straight cracks in the vertical direction, for the pavement layer with internal curved cracks, there are often debris such as stones larger than the bottom of the cracks (usually the size (2cm to 5cm) stuck in the middle of the crack, the high-speed airflow will bypass the stuck deposit, making it impossible to blow out, and once it remains inside the crack and the potting glue is poured, since the glue is not directly connected to the inner wall of the crack Contact, the weakening of the suction force will make it impossible to prevent the crack from continuing to expand, or a cavity will appear in the crack after the sediment is loosened, and it will need to be paved and repaired again after a period of time; 2. The dust blown from the crack will spread rapidly outside the crack, The working environment of the operator will become worse and worse with the progress of the cleaning work, and the diffused dust will be deposited in the remaining cracks, which will increase the difficulty of the subsequent cleaning work
