It is started from an evaluation of gas pipe protective building at oblique position accross the river bend with high discharge and dynamic flow contained trees, sand sediment, gravels up to boulder. The results of the failure analysis and evaluation on the previous building as follows: The structure is located on incorrect installation it is in oblique position exactly on the sharp curve of the river. The building is in such an alarming condition for the sub grade is eroded, saddle weight and anchor do not work properly due to erosion, upper flow and seepage flow. Gabions do not work properly they are tilted and lifted by the washed away by flood with its drift material. Due to the oblique position accross the river bend, an additional construction will be necessary.

This gas pipe requires a protective building to return it to its former condition that is buried in two meters deep. Therefore, a check dam construction is required. Due to the oblique position accross the river bend, an additional construction will be necessary as crib that will direct the flow with such combination of cribs and check dam. The aim and goal of gas pipe protection can be achieved, accordingly. The results of gas pipe protective building evaluation are as follows: All components of the substitute building shall work simultaneously and they are quite reliable as proven by the good physical condition until the building construction is completed and once flood occured. After ones time flooding, the structure stability remains in good condition, does not break, does not slide, and does not roll. The sedimentation is seen at the upstream of the cribs during the construction of main building and afterwards. The main building works properly as required and it is proven by sedimentation that already occurs at the upstream of the check dam.

它是从评估在整个河弯处倾斜位置的燃气管道保护建筑物开始的，该建筑物有高流量和动态流动，其中包含树木，沙子沉积物，砾石直至巨石。对先前建筑物的故障分析和评估的结果如下：该结构位于错误的安装位置，正好在河流的陡峭曲线上处于倾斜位置。由于路基被侵蚀，鞍座重物和锚因腐蚀，上流和渗流而无法正常工作，因此该建筑物处于这样的警报状态。石笼无法正常工作，它们会被冲刷的漂流材料冲走而倾斜和抬起。由于横跨河弯的倾斜位置，将需要额外的构造。

该煤气管需要保护建筑，以使其恢复到原来的状态，该状态被埋在两米深的地方。因此，需要建造止水坝。由于河弯处的倾斜位置，婴儿床将需要额外的构造，以这种婴儿床和止回坝的组合来引导水流。因此，可以达到保护气体管道的目的和目的。煤气管道防护建筑物评估的结果如下：替代建筑物的所有组件应同时工作，并且由良好的物理条件证明它们是相当可靠的，直到建筑物建造完成并且一旦发生洪水。经过一段时间的注水后，结构稳定性保持良好状态，不会破裂，不会滑动和不会滚动。在建造主体建筑期间及之后，在婴儿床的上游可以看到沉淀物。主楼可按要求正常运行，并已通过检查坝上游已发生的沉淀证明。
