Embodiment 1

[0048] This embodiment provides a pavement water seepage meter for road construction monitoring. Figure 1-Figure 6 As shown, it includes a base 1, the inner bottom of the base 1 has a cavity 13, the cavity 13 communicates with a measuring cylinder 6 through a first shut-off valve 7 arranged on the upper surface of the base 1, and the base 1 is also installed with a The air pump 9, the air outlet of the air pump 9 is connected with a second shut-off valve 8 through a hose, which communicates with the cavity 13, and the cavity 13 is also arranged on the base 1 for displaying the internal pressure of the cavity 13. The pressure gauge 10, the lower part of the base 1 can also be detachably clamped with a snap ring 3, and a three-dimensional silicone gasket 2 installed in the base 1 and located outside the edge of the cavity 13. The three-dimensional silicone gasket 2 at least includes an integral molding The horizontal ring 21 and the vertical ring 22 are used to fit the surface ...

Embodiment 2

[0052] As a preferred embodiment of the present application, this embodiment is further optimized and improved on the basis of Embodiment 1, and further, combined with figure 1 and figure 2As shown, in order to facilitate the installation of the base 1, the base 1 has an annular structure nested with the snap ring 3, and at least three snap pins 11 are evenly distributed on the circumferential side wall of the annular structure. The inner side wall of the vertical ring 31 of the ring 3 is provided with a plurality of notch grooves 33 for correspondingly snapping the bayonet 11. The notch groove 33 has a notch for the bayonet 11 to slide in, and the notch is connected smoothly. There is a straight groove extending horizontally along the inner wall of the vertical ring 31 , and the width of the straight groove is adapted to the outer diameter of the bayonet 11 . When installing the base 1, it is only necessary to hold the base 1 and apply downward pressure to rotate. When the ...

Embodiment 3

[0057] This embodiment provides a pavement water seepage detection method for road construction monitoring, which is realized by using the pavement water seepage meter described in the above-mentioned embodiment 2. Figure 1-Figure 9 The structure and schematic shown, specifically include the following steps:

[0058] Step STP100, site selection and measurement, select the position of the road surface to be measured, and measure the maximum outer diameter R and the minimum inner diameter r of the retaining ring 3 equipped with the road water seepage meter used;

[0059] Step STP200, groove depth measurement, use a cylindrical hole drill at the selected road surface position to open an annular groove vertically downward on the road surface for accommodating the snap ring 3, and the inner diameter of the annular groove is greater than the minimum inner diameter r of the snap ring 3 1-2mm smaller, the outer diameter of the annular groove is larger than the maximum outer diameter ...

Abstract

The invention discloses a pavement water seepage instrument for road construction monitoring and a detection method.The pavement water seepage instrument comprises a base, a cavity is formed in the bottom in the base, the cavity communicates with a measuring cylinder through a first shut-off valve arranged on the upper surface of the base, an air pump is further installed on the base, and an air outlet of the air pump is connected with a second shut-off valve communicating with the cavity through a hose; the cavity is further connected with a pressure gauge which is arranged on the base and used for displaying the internal pressure of the cavity, and the lower portion of the base is further detachably connected with a clamping ring in a clamped mode and a three-dimensional silica gel gasket which is installed in the base and located on the outer side of the edge of the cavity. According to the invention, the stress extrusion state of the three-dimensional silica gel gasket can be adjusted in a self-adaptive manner by adopting a detachable clamping mode of the clamping ring and the base, so that the sealing anti-pressure capability of the three-dimensional silica gel gasket can be adjusted to adapt to detected road bodies with different roughness; a plurality of sealing layers can be formed by adopting the three-dimensional silica gel gasket, so that the sealing between the water seepage instrument and the road surface is further improved, and the problem of abnormal leakage in the testing process is avoided.

Description

technical field [0001] The invention relates to the technical field of detecting the permeability of porous materials, in particular to the technical field of a detection device and method for the water seepage of a road body after road construction, and in particular to a road water seepage meter and a detection method for road construction monitoring. Background technique [0002] The road water seepage test is a method of detecting the quality of road construction. The water seepage test is carried out in accordance with the regulations stipulated in JJG (traffic) 104-2015 of the Ministry of Transport's dose verification regulations, and the road density is judged according to the time required for the detected water seepage. performance, so as to calculate the water seepage, load-bearing, settlement and other indicators of the road. [0003] Since only a simple structure is required according to the verification regulations, the existing water seepage meters have very si...
