A kind of propelling embankment machine and its embankment method

Abstract

The invention provides a push type diker and a diking method thereof. According to the push type diker and the diking method thereof, the diker is positioned to the position where diking needs to be conducted, and the diker is made to sink into silt gradually under the action of a jetting hole; then stones are thrown into a forming cabin of the diker, a piston rod of a pushing oil cylinder stretches out backwards to push the stones after the height of the stones is larger than that of the pushing oil cylinder on the diker, and forward counter-acting force can be provided for the whole diker by the stones due to the fact that firm silt behind the stones cannot be squeezed open by the stones; the jetting hole works all the time to activate and push open the silt in front and below, so that the diker advances to squeeze open the silt in front, and stones are thrown by the diker continuously when the diker advances, so that the lower portion of a sea dike is dump-filled; then the upper portion of the sea dike is dump-filled through a conventional method, so that construction of a dike body of the whole sea dike is completed. By the adoption of the push type diker and the diking method thereof, the constructed dike body can be well matched with a construction drawing, and stones can be saved; meanwhile, diking can be conducted under complicated geological conditions, and thus the push type diker and the diking method thereof are highly practical.

Description

technical field [0001] The invention relates to the field of seawall construction engineering, in particular to a push-type embankment machine and an embankment method thereof. Background technique [0002] Seawalls are embankments built in estuaries or coastal areas. The seawall directly bears the wind, waves, tide, and rapids. Generally, it is used as the main part of the sea reclamation project to control the water level of the enclosed area and meet the protection requirements of salt production, aquaculture, industrial land, transportation and shipping. [0003] In the seawall construction project, when the water depth is large, the silt layer is deep, and the water flow is relatively fast, the embankment is built around the sea. In the past, the controlled loading explosive silting displacement method, referred to as the explosive silting displacement method, was used. The Chinese patent with the patent publication number CN1477271A discloses a "Controlled Loading Exp...

AI Technical Summary

Problems solved by technology

Although the seawall can be built by the explosion-squeezed silt replacement method, there are many shortcomings: 1. The explosion is instantaneous, the explosion process is uncontrollable, and the result of the explosion is random. Silt replacement cannot guarantee that the external dimensions of the seawall and the elevation of the bottom surface of the seawall are consistent with the drawings; 2. It is difficult to adapt to complex geological conditions; 3. Explosion vibration will activate the bottom of the seawall and the surrounding silt, which may appear on the slope during actual construction. The silt and embankment slipped, causing serious quality accidents; 4. There are potential safety hazards in explosion operations
