[0121] Loading capacity test calculation example of pipe joints of prefabricated double warehouse circular arch comprehensive pipe gallery:
[0122] The pipe section of the comprehensive pipe gallery is a double-cabin circular arch section, and the size is mm, crack load is less than 0.2mm crack width, vertical test load Values refer to individual concentrated force vertical test load values. The distribution curve of horizontal earth pressure along the depth of the pipe joint embedded in the comprehensive pipe gallery , that is, the distribution curve of the horizontal earth pressure along the depth is linear. The bulk density of cohesive soil is 14 , the coefficient of earth pressure on the stationary side , crowd 5 , ground cover 10 , the height of the crowd and ground covering soil converted into equal-thickness soil column is , the height of the pipe section of the comprehensive pipe gallery It is divided into 4 sections, each section is 0.8m, and the r...

The invention discloses a testing device for a carrying capacity of a comprehensive pipe gallery and pipe joint and an application method, and relates to a device for testing the carrying capacity of the urban underground comprehensive pipe gallery and pipe joint and an application method. The main structure of the testing device is composed of the comprehensive pipe gallery and pipe joint, a test rack, a vertical bearing plate, a vertical jack, a vertical slide groove, a horizontal bearing plate, a horizontal jack and a horizontal slide groove and the like; the device can be used for simultaneously performing a vertical load test and a horizontal load test of the comprehensive pipe gallery and pipe joint; the horizontal load test can reasonably and accurately simulate horizontal soil pressure and meets an actual stress condition of the comprehensive pipe gallery and pipe joint; the detection accuracy of testing the carrying capacity of the comprehensive pipe gallery and pipe joint is improved, and reasonable and correct utilization and structure safety of the comprehensive pipe gallery and pipe joint are ensured; the corresponding application method is combined so that assembling and utilization of the testing device can be finished very well; and therefore, the testing device has the advantages of simple structure, convenient utilization, reasonable method, reliable data and the like, and has relatively high economic benefits and social benefits.
Description
technical field [0001] The invention relates to the field of testing the bearing capacity of pipe joints of urban underground comprehensive pipe gallery, in particular to a test device for the bearing capacity of pipe joints of urban underground comprehensive pipe gallery and a method for using it. Background technique [0002] There are nearly 30 types of pipelines in the seven major categories of water supply, heat, gas, electricity, telecommunications, rainwater, and sewage underground in cities in my country, which are managed by different departments. There is no accurate comprehensive map or database of pipelines at the national level, which leads to the fragmentation of construction units, which is inevitable. Pipeline "fighting" and repeated excavation of roads and other problems. Recently, the country has begun to pay attention to and comprehensively start the construction of urban underground comprehensive pipe corridors, that is, all pipelines will be concentrated ...
