Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway infrastructure technology, and in particular to a soft foundation reinforcement device for highway engineering construction. Background Technology
[0002] Soft soil layers with low strength and high compressibility often contain a certain amount of organic matter. Due to their low strength and large settlement, soft soil often poses a great threat to road engineering. If not handled properly, it can have a significant impact on the construction and use of highways.
[0003] To mitigate the impact of soft soil foundations on highway construction, existing technologies often utilize cement or lime as the main solidifying agent. Specialized deep-mixing machinery forces the soft soil and solidifying agent (slurry or powder) deep within the foundation, utilizing a series of physical and chemical reactions between the solidifying agent and the soft soil to solidify it into a foundation with integrity, water stability, and a certain strength. For example, the soft soil foundation reinforcement structure disclosed in CN219793493U uses a rotating connecting plate, which is connected and fixed to the connecting ring via a locking assembly. Each reinforcing pile is inserted into a pile hole, and adjacent first and second connecting plates are connected by the connecting assembly. This can reduce the differential settlement between the reinforcing piles. However, the reinforcement structure uses a single connection method with extremely limited contact area. Furthermore, the soft soil foundation itself is porous, and under the combined action of the highway substrate and external pressure, the reinforcement structure can easily sink deep into the soft soil, severely impacting the safety of highway construction and use. Utility Model Content

A through hole is provided at the middle of the load-bearing base, and an extended base plate placed horizontally on the soft soil foundation is fixedly fitted onto the load-bearing base through the through hole. Countersunk holes are provided at the four corners of the load-bearing base, and embedded columns inserted vertically into the soft soil foundation are fixedly fitted onto the load-bearing base through the countersunk holes. A load-bearing plate for laying highway substrate is provided on the load-bearing base through the embedded columns.
[0007] Preferably, the load-bearing base is a rectangular frame structure, and the upper end of the load-bearing base is provided with a through hole for fixing the extension base plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figures 1-6 A soft soil foundation reinforcement device for highway construction includes a load-bearing base 1 placed on a soft soil foundation, as detailed in the attached instruction manual. Figure 2 With appendix Figure 3 The load-bearing base 1 is a rectangular frame structure. By placing the flat load-bearing base 1 horizontally on the soft soil foundation, the contact area between it and the soft soil foundation is increased, thereby reducing the pressure effect.
[0029] The load-bearing base 1 has a through hole 2 at the middle position, and the load-bearing base 1 is fixedly fitted with an extension base plate 4 that is placed horizontally on the soft soil foundation through the through hole 2. The upper end of the load-bearing base 1 has a locking hole that connects to the through hole 2 and is used to fix the extension base plate 4. The load-bearing base 1 and the extension base plate 4 can be flexibly disassembled and assembled to realize the flexible use of the reinforcement equipment.
[0030] The load-bearing base 1 has countersunk holes 3 at each of its four corners, and the load-bearing base 1 is fixedly fitted with embedded columns 7 vertically inserted into the soft soil foundation through the countersunk holes 3. The load-bearing base 1 is provided with load-bearing plates 11 for laying road base material through the embedded columns 7. By setting the embedded columns 7 at the four corners of the load-bearing base 1, the balance of the load-bearing base 1 on the soft soil foundation can be maintained, and the load-bearing base 1 can be prevented from tilting on the soft soil foundation.
[0031] The extended base plate 4 has symmetrically opened storage cavities 5 at its ends, and a horizontally abutting plate 6 is rotatably installed in the storage cavity 5. The overall structure of the extended base plate 4 is flexible and adjustable, making it easy to disassemble and store. The unfolded extended base plate 4 can further increase the contact area between the load-bearing base 1 and the soft soil foundation.
[0032] The embedded column 7 is a hollow cylindrical structure with an open top, and the embedded column 7 has a seepage hole 8. The seepage holes 8 are distributed in a straight line in the vertical direction at equal intervals to form a multi-layered reinforcing bolt 1002.
[0033] The top opening of the embedded column 7 is fixedly fitted with a feeding hopper 9 placed horizontally on the soft soil foundation, and the embedded column 7 is filled with concrete reinforcing bars 10 through the feeding hopper 9. The load-bearing plate 11 and the concrete reinforcing bars 10 are provided with corresponding fixing through holes 12.
[0034] The hopper 9 consists of a hopper body 901 and a plate body 902. The hopper body 901 is vertically fitted into the opening at the top of the embedded column 7, and the plate body 902 is horizontally in contact with the soft soil foundation, so as to fill the embedded column 7 with concrete material mixed with curing agent.
[0035] The concrete reinforcing bar 10 is composed of a column 1001 and a reinforcing bolt 1002. The column 1001 is vertically fitted into the bucket body 901 and the embedded column 7, and the reinforcing bolt 1002 extends into the soft soil foundation through the seepage hole 8. The concrete material forms a divergent shape through the seepage hole 8, and after solidification, it forms the concrete reinforcing bar 10, so that the embedded column 7 is fixedly embedded in the soft soil foundation.
[0036] It should be noted that the specific model and specifications of the embedded column 7 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.
[0037] The functional principle of this utility model can be explained through the following operation methods:
[0038] Place the load-bearing base 1 horizontally on the soft soil foundation;
[0039] The base plate 4 is extended horizontally through the perforation 2, and the tension plate 6 is unfolded from the storage cavity 5, so that the extended base plate 4 and the tension plate 6 are placed horizontally on the soft soil foundation.
[0040] The ground-embedded column 7 is vertically installed through the countersunk hole 3, and the feeding hopper 9 is installed in the ground-embedded column 7, so that the feeding hopper 9 is placed horizontally on the soft soil foundation.
[0041] Concrete material is filled into the embedded column 7 through the hopper 9, and the concrete material extends from the seepage hole 8 into the soft soil foundation, and then solidifies into concrete reinforcing bar 10.
[0042] The load-bearing plate 11 is fixed on the concrete reinforcing bar 10, and the highway substrate is laid on the load-bearing plate 11.
