Description

Submerged line boundary pile for measuring construction sign land and immigration engineering Technical Field The utility model relates to engineering boundary piles, in particular to a submerged line boundary pile for construction land and civil engineering measurement. Background The submerged line boundary pile for measuring the construction sign land and the immigration engineering is an important basis of the reservoir immigration physical index investigation stage after the construction stop notification of the hydropower engineering project is issued to the approval stage, and is an important content of the immigration arrangement planning design. In the physical index investigation stage, different types of boundary piles (such as population piles, land piles and horizontal piles) respectively correspond to different submerged objects, are used for the work of boundary confirmation, clear weight, index registration, planning design and the like of various objects in the physical index investigation stage, and are important achievements before the approval construction of the hydropower engineering. The submerged boundary pile for traditional hydroelectric engineering measurement mainly comprises reinforced concrete piles, wooden piles, exposed rock carving marks and the like. The most common concrete boundary piles in the permanent boundary piles have the greatest problems of large weight and inconvenience in carrying, meanwhile, the boundary piles have the defects of easily weathered surface and inconvenience in long-term use, the surface of the concrete boundary piles is not attractive, the concrete boundary piles are difficult to observe and find in a remote place during use, the concrete boundary piles are large in operation surface, large in concrete consumption, large in workload and the like in the field burying process, the universality and the boundary pile testing working efficiency are reduced, and the energy conservation and the environment friendliness are not facilitated. Disclosure of utility model The utility model aims to solve the technical problem that the existing concrete submerged boundary pile is large in weight and inconvenient to carry, and one of the purposes of the utility model is to provide a submerged boundary pile for construction sign land and immigration engineering measurement, which is convenient to carry. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a construction sign land and immigration engineering measurement are with inundating line boundary stake, includes the pile body, the top surface of pile body sets up to the standard face, its structural feature lies in: the pile body comprises a first cylinder body and a second cylinder body, the cross section area of the first cylinder body is larger than that of the second cylinder body, the lower end of the first cylinder body is connected with the upper end of the second cylinder body, concrete is filled in the first cylinder body, a mortar filling opening is formed in the upper portion of the second cylinder body, and mortar overflow holes are distributed in the cylinder body of the second cylinder body. Preferably, the first cylinder and the second cylinder are respectively made of stainless steel materials, fixing steel bars are distributed at different height positions of the second cylinder, the fixing steel bars traverse the second cylinder, and the end parts of the fixing steel bars extend out of the second cylinder. Preferably, the first cylinder and the second cylinder are made of 304 stainless steel material with the thickness of 1-3 mm. Preferably, the diameter of the first cylinder is phi 140mm so as to meet the requirement of 100mm of the side length of the square mark surface at the upper part of the concrete boundary pile in the specification, and meanwhile, mark surface lettering can be reasonably arranged and clearly visible, and the diameter of the second cylinder is phi 60mm so as to facilitate the transportation of the boundary pile. Preferably, when the submerged line boundary pile is used, cement mortar is injected into the second cylinder, and the cement mortar overflows from the mortar overflow hole to wrap surrounding soil and the second cylinder. Preferably, the back of the mark surface is provided with a back plate so as to avoid laser lettering and surface penetration damage when the back of the mark surface is welded with the surrounding pile body. Preferably, the whole length of the pile body is 1-1.4m, and the whole weight is 5-10kg. Preferably, the diameter of the mortar overflow hole is phi 20mm and is uniformly distributed, so that cement mortar poured into the second cylinder can fully flow out of the mortar overflow hole when the pile is buried, and the stability of the boundary pile is enhanced.
