The invention relates to the technical field of cable trenches, discloses a prefabricated cable trench, and solves the problem that a related prefabricated cable trench is prone to stress damage due to settlement deformation of a foundation. The prefabricated cable trench comprises a plurality of trench bodies mounted in a foundation pit, and the trench bodies are mutually inserted in the length direction; a plug-in assembly and a locking assembly which enables the plug-in assembly to be plugged more tightly are arranged between every two adjacent trench bodies; a gravel layer is laid in the foundation pit, a hollow pipe is fixed to the lower surface of the trench body, the hollow pipe is inserted into the gravel layer and is connected with the gravel layer in a penetrating mode, a communicating channel connected with the hollow pipe in a penetrating mode is formed in the trench body, and quick-setting mortar is injected into the communicating channel, so that the stress damage phenomenon of the cable trench is reduced, and the service life of the cable trench is prolonged. And the protection capability of the prefabricated cable trench on the underground cable is improved.
本申请涉及电缆沟的技术领域，其公开了一种预制装配式电缆沟，解决相关的装配式电缆沟容易受到地基的沉降变形而出现应力损伤的问题，其包括安装在基坑内的多个沟本体，多个所述沟本体沿长度方向相互插接，相邻的两个沟本体之间均设有插接组件和使插接组件插接更加紧密的锁紧组件；所述基坑内铺设有砾石层，所述沟本体的下表面固定有空心管，所述空心管插入砾石层内且与砾石层贯通连接，所述沟本体内开设有与空心管贯通连接的连通道，所述连通道内注有速凝砂浆，由此减少电缆沟出现应力损伤的现象，提高预制电缆沟对地下电缆的保护能力。
