Convenient prefabricated equipment has the characteristics of energy saving and high efficiency, green environmental protection, excellent quality, and high construction precision.

[0003] The existing temporary earth dams for fill roadbeds are mostly constructed by on-site workers and mortared. There are shortcomings in on-site construction, such as long construction time, low efficiency, and high labor costs. In addition, it is easy to cause human-caused accidents during on-site construction, which can easily lead to low construction quality and construction accidents. In addition, when temporary earth dams are constructed by on-site workers or machinery such as excavators, they are generally unable to be effectively vibrated and compacted, and the construction quality is low, which does not meet the quality requirements, and the construction gap is large and unsightly. Mortaring is also a manual process, and manual mortaring is inefficient and of poor quality. Utility Model Content

The earth dam construction module and the earth dam surface mortar finishing module are integrated into one by an inverted groove-type casing, thereby realizing the continuous operation of earth dam construction and mortar finishing. The casing is mainly made of steel structure material, which has the characteristics of high strength and good durability. While playing a supporting role, it can also play a good protective role for the other components. In addition, a group of traction mechanical arms are also arranged at the front end of the casing. The traction mechanical arms are also composed of steel structures. The main function is to be mechanically connected to the assembled vehicle to provide traction support for the earth dam paving device for the fill roadbed. The connection method is reliable and convenient.

[0024] In the utility model, the soil feeding mechanism includes a soil adding funnel and a material leakage channel. The soil adding funnel is connected to the mold cavity of the dam-building mold through the material leakage channel. The external soil enters the material leakage channel through the soil adding funnel, and finally enters the mold cavity of the dam-building mold to form a target-shaped earth dam through the molding action of the dam-building mold. In a preferred embodiment, a first booster pump is also arranged between the soil adding funnel and the material leakage channel. The first booster pump mainly pressurizes the soil entering the material leakage channel, so that it quickly passes through the material leakage channel and enters the mold cavity of the dam-building mold and fills the mold cavity of the dam-building mold with soil. Further, a vibration screening plate is also arranged inside the soil adding funnel. The vibration screening plate is mainly composed of a rigid screen plate, a rigid spring and a micro vibration motor (by directly purchasing a mature product with a vibration screening function on the market). It mainly screens the soil entering the soil adding funnel and screens out larger objects or longer objects to avoid damage to the first booster pump.

[0025] In the utility model, the dam-building mold includes a dam-building top plate and a dam-building side plate. The dam-building top plate is horizontally arranged and a pair of dam-building side plates are symmetrically arranged on both sides of the dam-building top plate in the width direction (the width direction of the earth dam) to form an inverted groove-shaped mold cavity (similar to the inner cavity structure of the casing), and the outer side (referring to the outer side of the mold cavity) of the dam-building top plate and the dam-building side plate are connected to the inner wall of the casing through an independent front connecting rod. In a preferred embodiment, the leakage channel is a folding and retracting elastic channel (similar to the structure of a foldable and retractable straw), and the front connecting rod is a telescopic connecting rod (mainly including a power cylinder and a sleeve-type telescopic rod, such as a hydraulic telescopic rod, an electric telescopic rod, which is a mature product that can be directly purchased on the market), and a front annular slide rail extending along its circumference is also arranged on the inner wall of the casing. Each front connecting rod is connected to the front annular slide rail through an independent slide seat (the front connecting rod and the slide seat can be hinged through a universal joint). That is to say, the front connecting rod can be adjusted by telescopic adjustment and can also move semicircularly along the front annular slide rail. A horizontal slide rail extending along the width direction is arranged on the lower plate surface of the damming top plate, and the upper ends of the two damming side plates are respectively connected to the horizontal slide rail through independent slide seats, and the upper ends of the two damming side plates are hinged to the slide seats (for example, hinges are used for hinge connection). The relative position relationship between the damming top plate and the damming side plates can be adjusted by the telescopic and circular movement of the front connecting rod, thereby achieving the purpose of adjusting the shape and size of the mold cavity inside the damming mold, thereby improving the application range of the device and improving its applicability and practicality. It should be noted that the front end opening of the groove-shaped cavity of the dam-building mold is an outward-expanding opening, and the soil from the leakage channel mainly enters the range of the outward-expanding opening for accumulation, and then when it moves forward with the random shell, the soil inside can enter the rear earth dam compaction template. Because the unit volume of the earth dam compaction template is small, the soil will be compacted once, and the vibration mechanism (such as a vibration motor) will work at the same time, using a certain frequency for vibration compaction. Make the interior of the soil further filled and more dense. It should be noted that in the present utility model, the vibration mechanism can be directly set on the dam top plate and dam side plate of the dam-building mold, or it can be set on the front connecting rod (the vibration mechanism on the plastering mold can also be set in this way).

[0026] In the present invention, the overall structure of the plastering mold is similar to that of the dam-building mold (but without the outward-expanding opening), but during use, it is necessary to adjust its size so that the internal groove-shaped plastering cavity is one size larger than the groove-shaped mold cavity, mainly to leave space for grouting plastering. For example, if the thickness of the mortar plastering is 3 cm, the overall diameter of the plastering cavity (diameter in the radial plane) needs to be adjusted to be 3 cm larger than the diameter of the mold cavity.

[0027] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0028] 1: The earth dam paving device for fill roadbed of the utility model can quickly build and plaster the temporary earth dam for fill roadbed, can operate continuously, has high construction efficiency, uniform mortar plastering, and stable and reliable structural strength of the earth dam (even a temporary structure can be realized to replace a permanent structure). In addition, the device adopts an assembled structure, and can change the construction and size according to the on-site conditions, and can adapt to various working conditions.

[0029] 2: The earth dam paving device for fill roadbed of the utility model has the advantages of simple overall structure, easy operation, low investment cost, low labor intensity, high production efficiency and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
