Description

Accurate injection device of gluing agent

Technical Field

The application relates to the field of chemical anchor bolt construction, in particular to an accurate adhesive injection device.

Background

At present, the overhead line system hanging post in the domestic tunnel generally adopts two fixing modes of a reserved channel and a post channel. The two modes have respective advantages and disadvantages, wherein the construction of the rear-mounted channel is simple and convenient, and the cost is greatly reduced compared with that of the pre-buried channel. The post-channel construction mostly adopts the installation form of embedding the chemical anchor bolt, and the construction process comprises positioning measurement, drilling, embedding the chemical anchor bolt, drawing test, installation of a channel and the like.

After positioning measurement is carried out on a construction site, a percussion drill is used for drilling, loose concrete scraps on the inner wall of a hole are brushed away by a steel brush, then floating ash and scraps in the hole are blown out by an air cylinder, chemical anchor bolt glue is injected according to construction experience and is buried into the chemical anchor bolt, the chemical anchor bolt glue is waited to be completely cured according to the temperature and time required by a product, the chemical anchor bolt is strictly forbidden to be triggered within the glue curing time so as to prevent curing failure, a detection instrument is used for carrying out a drawing test on the chemical anchor bolt after curing, and a contact net channel is installed after meeting the design requirement.

In the construction process of the contact net in the tunnel, because the demand of the chemical anchor bolt is large, the cost of the chemical anchor bolt and the glue is high, the situation that the chemical anchor bolt is unqualified in the drawing test of the chemical anchor bolt due to the insufficient glue injection is easy to occur when the chemical anchor bolt glue is injected by the traditional construction experience value method, the drilling operation needs to be carried out again and the chemical anchor bolt needs to be embedded, lead to doing over again or even delay time limit for a project, also appear glue to pour into excessively and cause the condition of glue outflow or drippage easily, lead to the waste of glue, to outflow or drippage to the glue that chemical anchor bolt exposes screw thread department, must in time clear up, avoid glue solidification back influence chemical anchor bolt screw thread's normal use, these two kinds of circumstances all can increase construction cost.
