Description
Technical field
Road engineering testing equipment field is the utility model is related to, specifically a kind of glue injection type coring tube.
Background technology
Pavement detection corning machine is one of detection device being most widely used in road engineering detection, mainly for detection of
The parameter such as road surface, Laminate construction thickness, intensity.Conventional pav detects coring model machine, by motor driven coring bit rotary coring,
Need manual operation column to move up and down motor and drill bit coring, drill through depth and manually control, do not measure accurately
Control core sample thickness；After the completion of coring, the pit-hole left on road surface then continues by manually filling up, can not accurate measurement compacting journey
Degree, larger so as to cause benefit hole error, general effect is bad.
Coring tube in the prior art be present, in some ground location of the coring procedure are carried out, easily crush the rubble in ground,
Cause the core body of taking-up sufficiently complete.
Utility model content
The utility model purpose there is provided a kind of simple in construction, can quickly be bonded together broken foundation stone, really
The glue injection type coring tube of the integrality of the core of the taking-up of guarantor.
The utility model solves technical problem and provides following scheme：
A kind of glue injection type coring tube, including cylinder, it is characterised in that：The side wall of the cylinder is provided with hollow cavity, described
The inwall of hollow cavity is provided with multiple hole for injecting glue, and the top connection injecting glue pipeline of the hollow cavity, the inside of the cylinder is provided with
Core body room, the top sidewall of the core body room are provided with passage, and the core body indoor top is provided with die pad.
Die pad edge in the coring tube is provided with the bending edges inwardly dug.
The utility model is provided with hollow cavity, and the top connection injecting glue pipeline of hollow cavity in cylinder inboard wall, and in cylinder
Side wall is provided with hole for injecting glue, so when carrying out foundation drilling coring, while carries out injecting glue operation, and the foundation stone being broken is bonded
Together, and in cylinder die pad is provided with, by being provided with passage in the top of die pad, is easy to blow out core material.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
