Method for judging leakage of waterproof curtain of foundation pit by using artificial heat source and temperature tracing of underground water

The invention relates to a method for judging leakage of a waterproof curtain of a foundation pit by using an artificial heat source and the temperature tracing of underground water. The method comprises the following specific steps of: 1) performing geological exploration of geotechnical engineering and field survey to determine the relative hydrogeology parameters of a targeted foundation pit, wherein the relative hydrogeology parameters comprise an osmotic coefficient, a thermal coefficient, a water storage coefficient and the like; 2) reasonably arranging observation wells inside and outside the pit by using the original well site to ensure that two sides of the waterproof curtain covering the foundation pit are not leaked; 3) measuring the initial temperature field parameters of drilled holes inside and outside the targeted foundation pit on site to obtain the distribution characteristic, the normal value and the like of the foundation pit; 4) applying the heat source to the drilled hole outside the foundation pit to ensure that the temperature in the drilled hole outside the foundation pit is raised; and 5) measuring the temperature in the drilled hole inside the foundation pit, analyzing and judging according to the obtained initial temperature field value, reasoning by combining knowledge of thermodynamics, and judging and positioning the possibly leaked points. The method is definite in principle and high in adaptability; under the condition that the original observation well is utilized, the observation well can be increased appropriately; the leakage of the foundation pit is judged by applying the heat source into the drilled hole outside the pit actively; and the temperature field of the underground water of the observation wells is analyzed and judged by combing the knowledge of thermodynamics, so that the double aims of judging and positioning the leakage of the foundation pit can be fulfilled quickly and conveniently.

Building decoration equipment with ceramic tile seam beautifying automatic treatment function

The invention relates to building decoration equipment with a ceramic tile seam beautifying automatic treatment function. The building decoration equipment comprises a grooving device, an ash cleaningdevice and a wiping-drying device. The ash cleaning device is mounted in the middle of the grooving device, and the wire-drying device is mounted at the rear end of the grooving device. According tothe building decoration equipment, the difficult problems that in traditional seam beautifying, ceramic tile seam grooving, ash cleaning and ceramic tile face wiping-drying need to be manually conducted, in grooving, personnel need to conduct grooving on the ceramic tile seams by means of tools, manpower is wasted, deflect grooving is prone to occurring, the tools scratch the work personnel to cause the potential hazards in the grooving process due to excessive strength, in ash cleaning, the ceramic face is wiped and washed manually, manual ash cleaning is uneven and prone to causing omittingof the position needing to be subjected to ash cleaning, in wiping-drying, the personnel usually only wipe the ceramic tile face once by means of tools and then wipe the next position, and thus wiping-drying is incomplete can be solved, and the functions of automatic grooving, wiping-washing and wiping-drying can be achieved for the ceramic tile seams.
