Concrete permeation detecting device

Abstract

The invention discloses a concrete permeation detecting device. The device comprises an extruding mechanism, a tray mechanism, a box, a drive mechanism, a support and a partition, wherein the box is arranged in the support, the tray mechanism is connected with the support through the box, and the extruding mechanism is arranged at the upper part of the support and connected with the drive mechanism; the partition is arranged in the middle of the box, and a water collecting module is arranged at the lower part of the partition. Water flow is generated in a gap of a roadbed material during extrusion and washes the roadbed material, the extruding time is controlled through a controller, tens of thousands of extrusion in the true environment are simulated in very short time, the amount of permeated water is observed after a test ends, the most real permeation information is acquired, and the phenomenon of data inaccuracy due to natural permeation is avoided. The concrete permeation detecting device is simple in structure, simple and convenient to operate and worth popularization and application.

Description

technical field [0001] The invention belongs to the technical field of road base material test devices, and in particular relates to a concrete penetration detection device. technical background [0002] With the progress and development of social civilization, the road network is expanding rapidly, and the traffic volume is also increasing geometrically. Especially in the transportation of goods, the phenomenon of vehicle overloading and exceeding the limit is serious. In the case of continuous extrusion of the road, the road surface is damaged. Especially in the process of continuous extrusion of high-grade pavement, if the concrete material seeps, it will easily lead to water ingress in the base layer, which will aggravate the damage of the roadbed. Under the action of the load, the vehicle rolls the watery road surface to generate high-strength water flow, which scours the top layer of the roadbed, causing some materials to separate from the whole, creating gaps and holl...

Problems solved by technology

First, start the water pump motor to spray high-pressure water with adjustable pressure from the nozzle. When the main motor runs continuously, the slider moves left and right on the guide rail, driving the high-pressure water sprayed from the nozzle to repeatedly wash the surface of the test piece; although it has a certain practical effect Simulation, but it does not really simulate when the car rolls the road surface, because the high-pressure water flow is generated in the gap when the road surface is squeezed by the road surface, so that the water flow is pressurized downward, thereby accelerating into the concrete, and the water flow of this device is only in the concrete. Surface, so the measured data is still not real enough, and its structure is complex, so a test device that can truly simulate the real data of concrete road response is needed
