Guide car for piling construction of embankment project

Abstract

The invention relates to a guide vehicle for piling construction of river embankment engineering. The guide vehicle for piling construction of river embankment engineering is characterized in that the guide vehicle comprises a front vehicle frame and a rear vehicle frame, and the front vehicle frame and the rear vehicle frame are detachably locked to pile bodies inserted in soil; the front vehicle frame and the rear vehicle frame are connected through a driving structure, and the driving structure is used for driving the front vehicle frame and the rear vehicle frame to slide relative to the arrangement direction of the pile bodies; and a guide frame provided with a guide space allowing the lower sections of the pile bodies to be inserted therein is arranged on the front portion of the front vehicle frame, and the guide space of the guide frame can extent out to the position in front of the pile body at the headmost end so as to allow the lower sections of the pile bodies to be inserted therein. The guide vehicle for piling construction of river embankment engineering is reasonable in structural design, and positioning of the pile bodies is accurate; and the guide vehicle can move forwards step by step, so that the pile bodies to be inserted in soil are guided conveniently.

Description

technical field [0001] The invention relates to a river, lake and river coast embankment project, in particular to a guide vehicle for piling construction of the river, lake and river coast embankment project. Background technique [0002] In the current coastal embankment projects of rivers and lakes, when concrete piles and other components are used to build embankment protection walls, piling construction needs to be carried out on the embankments of rivers, lakes and seas. In practice, the piling guide equipment often used in embankment construction is simple Rectangular frame structure, during the construction operation, the frame structure is first set on the fixed member at the starting point of the project, then the pile body is inserted into the frame structure and driven into the soil, and then the adjacent pile bodies are driven side by side into the soil to Splicing together, but when using this frame structure guided piling construction, the single pile body is ...

Problems solved by technology

[0002] In the current coastal embankment projects of rivers and lakes, when concrete piles and other components are used to build embankment protection walls, piling construction needs to be carried out on the embankments of rivers, lakes and seas. In practice, the piling guide equipment often used in embankment construction is simple Rectangular frame structure, during the construction operation, the frame structure is first set on the fixed member at the starting point of the project, then the pile body is inserted into the frame structure and driven into the soil, and then the adjacent pile bodies are driven side by side into the soil to Splicing together, but when using this frame structure guided piling construction, the single pile body is easy to deviate left and right, and it is difficult to locate accurately, which makes it difficult to splice the piles, so the construction efficiency is very low, and the progress of the project is slow. The most important thing is to affect the quality of the embankment project; moreover, the guiding device is simple and heavy, and it is difficult to move by itself during construction, and it needs to be hoisted again with the help of a crane, which further affects the construction progress

At present, there is a kind of construction of river bank revetment works using special engineering ships, such as a Chinese utility model patent "special engineering ship for river channel and lake bank construction" with a patent number of ZL201420439985.3 (announcement number is CN204078022U) discloses such a construction device , including the hull, the brackets and piling devices installed on the hull. Although this type of engineering ship has lower requirements for the roads on both sides of the river, and there is no need to set up cofferdams during construction, because the ship is in the water, it will inevitably shake. During the piling process, the support on the ship is easy to shake and difficult to locate, and the pile body is difficult to locate and splice, so it still has the defects of slow construction progress and low piling accuracy

In engineering practice, there is currently no guiding mechanism that can accurately locate piles to facilitate splicing of piles and improve engineering quality.
