Problems solved by technology
[0005] In order to solve the above-mentioned technical problems, the present invention provides an anti-settlement structure at the junction of soft soil roadbed and normal roadbed to solve the problem that settlement is prone to occur at the junction of soft soil roadbed and normal roadbed. Settlement blocks, which have no anti-settlement structure in contact with soft soil subgrades and normal subgrades, have poor anti-settlement effects and are prone to settlement problems

Embodiment
[0032] as attached figure 1 to attach Figure 9 Shown:
[0033] The present invention provides an anti-subsidence structure at the junction of soft soil roadbed and normal roadbed, including: soft soil roadbed 1, anti-settling mechanisms 5 whose number can be increased or decreased are placed at the junction of soft soil roadbed 1 and normal roadbed 2, and the uppermost anti-settling mechanism 5 The top of the settlement mechanism 5 is fastened with a top pressing block 4; a set of extrusion mechanisms 6 is arranged between each adjacent two groups of anti-settling mechanisms 5; the top surface of the top pressing block 4 is in the The same level, and the soft soil subgrade 1, the normal subgrade 2 and the top surface of the top pressure block 4 are jointly laid with a layer of covering layer 3; the anti-subsidence mechanism 5 includes an embedded mechanism 5010, and a set of embedded components is slidingly installed inside the circular sliding cavity 506. Mechanism 5010, and...

The invention provides an anti-settlement structure at the junction of a soft soil subgrade and a normal subgrade, relates to the technical field of anti-subsidence structures, and solves the problem that subsidence is prone to occur at the junction of the existing soft soil subgrade and the normal subgrade, but the currently used anti-subsidence structure is only a single superimposed placement The anti-settlement block has no anti-settlement structure contact with the soft soil subgrade and normal subgrade, and the anti-subsidence effect it plays is not good, and the problem of settlement is still prone to occur. The anti-settlement structure at the junction of the soft soil subgrade and the normal subgrade includes the soft soil subgrade, and the anti-subsidence mechanism whose number can be increased or decreased is placed at the junction of the soft soil subgrade and the normal subgrade. During installation, the corresponding number of anti-settlement mechanisms can be selected according to the depth of the groove dug at the junction of the soft soil subgrade and the normal subgrade. In the installed anti-settling mechanism, the cylinders B are respectively embedded and inserted inside the soft soil roadbed or normal roadbed to further enhance the anti-settling effect of the anti-settling mechanism.
Description
technical field [0001] The invention belongs to the technical field of anti-subsidence structures, and more specifically relates to an anti-subsidence structure at the junction of a soft soil roadbed and a normal roadbed. Background technique [0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management with roads as the object and the engineering entities involved. Like any other civil engineering, road engineering has obvious technical, economic and The characteristics of management, the subgrade is the foundation of the track or road surface, and it is a geotechnical structure formed by excavation or filling. The static load and dynamic load of vehicles or road surfaces and traffic loads, and at the same time transmit and spread the load to the depth of the foundation. In road engineering, the junction point between the soft soil subgrade and the normal subgrade is the weakest part of the entire road. During the proce...
