Description

High moisture content peat soil foundation assembled reinforcing apparatus

Technical Field

The invention belongs to the technical field of foundation treatment devices, and particularly relates to an assembled type reinforcing device for a high-moisture-content peat soil foundation.

Background

Peat soil is a type of soft soil, and the cause of the peat soil determines that the peat soil is generally distributed in areas with luxuriant vegetation, such as seas, drowning valleys and the like. The artificial turf soil has the obvious characteristics of high compressibility, high water content, low strength, high sensitivity and the like, and southeast Asia countries such as Malaysia and the like have the disadvantages of abundant annual rainfall, dense vegetation, wider peat soil distribution and high natural water content of over 200 percent in some areas due to the fact that the countries are in the tropical zone, so that the roads constructed on the peat soil foundation are easy to generate the hazards of unstable subgrade, large post-construction settlement and the like. The current common methods for processing peat soil foundations mainly comprise the following methods: excavation and filling, overload prepressing, gravel piles, sand piles, tubular piles, jet grouting piles, stirring piles and the like. Because the peat soil is widely distributed, sufficient earthwork is not available for replacement and pre-pressing. Chinese patent CN204875753U discloses a foundation stabilization modular structure, including a plurality of module frame body, the frame body of module frame body for having well cavity, the frame body of module frame for having well cavity, embedding convex body, rear end are equipped with the back embedded groove before the front end of module frame body is equipped with, and the left end is equipped with left embedding convex body, right-hand member and is equipped with the right embedded groove, and the preceding embedding convex body of back side module frame body cooperates with the back embedded groove of front side module frame body, and the left embedding convex body of right side module frame body cooperates with the right embedded groove of left module frame body, adopts the embedded structure of four positions all around promptly in order to form a firm overall structure to closely cooperate with the ground stake to strengthen soft soil layer's cohesion. However, the reinforcement modular structure needs to be matched with a ground pile, and when pile foundation construction is adopted, the required manpower and material resources are high in cost, and the risk that the pile foundation sinks or the pile foundation is toppled over can occur when the ground pile is used in peat soil with high water content.

The right triangle body has stable structure and can stabilize the balance board to a horizontal state.

Preferably, the upper plate has a length of 20m, a width of 5m, and a thickness of 2 m.

Compared with the prior art, the invention has the beneficial effects that:

(1) be equipped with rotatable balance plate on the device's the curb plate, not only be convenient for transfer this reinforcing apparatus to the peat soil in, when being fixed to the horizontality with the balance plate in addition, usable high moisture content peat soil is to the buoyancy of balance plate and the stability of balance plate self in order to guarantee this reinforcing apparatus, avoids sinking.

(2) The side of last board is equipped with the slot and the lug of looks adaptation to be equipped with the same screw hole on slot and the lug, thereby can splice a plurality of reinforcing apparatus and make up the use, the assembly process is convenient quick.
