摘要：【中文】本发明提供了一种T梁中梁有限空间内负弯矩施工吊篮及使用方法，包括支撑座,支撑座两侧设有多个螺杆,螺杆与支撑座螺纹连接,所述支撑座上方两侧设有可折叠的第三护栏与第二护栏,所述第三护栏与第二护栏上设有多个钢丝绳,钢丝绳端部设有吊钩，采用折叠式护栏便于吊篮能进入T梁中梁有限空间，采用螺杆支撑在T型梁的梁靴上，吊钩挂在T型梁的箍筋上，上吊下撑式结构，吊篮整体更加稳固，调节螺杆使用不同宽度的T型梁的梁靴适用范围广，两侧的护栏高度不同，方便张拉设备进出，多重保护，稳固牢靠，成本低，适合推广使用。 【EN】The invention provides a hogging moment construction hanging basket in a limited space of a middle beam of a T-shaped beam and a using method thereof, wherein the hanging basket comprises a supporting seat, a plurality of screw rods are arranged on two sides of the supporting seat and are in threaded connection with the supporting seat, a foldable third guardrail and a foldable second guardrail are arranged on two sides above the supporting seat, a plurality of steel wire ropes are arranged on the third guardrail and the second guardrail, lifting hooks are arranged at the end parts of the steel wire ropes, the hanging basket can conveniently enter the limited space of the middle beam of the T-shaped beam by adopting the foldable guardrails, the hanging hooks are supported on beam shoes of the T-shaped beam by adopting the screw rods and are hung on stirrups of the T-shaped beam, an up-hanging and down-supporting structure is adopted, the hanging basket is integrally more stable, the application range of the T-shaped beam shoes with different widths for adjusting the screw rods.

摘要：【中文】本发明公开了一种泡沫混凝土及采用其进行路面沉陷修复的方法，该泡沫混凝土包括按重量份计的以下原料：水泥40~70份、铜尾矿粉10~30份、石粉10~20份、外加剂1~5份、发泡剂1~12份和水15~35份。具体路面沉陷修复时，通过压注式将其注入到待修复的部位，该泡沫混凝土与原路基填料性能相近，伍配性好，处理后可有效改良路基强度，减少因前后材料差异大，产生集中荷载，从而继续出现不均匀沉降的现象；而且压注式工艺能够借助填充压力顶托已沉降的路面面层，达到自适应恢复沉降面层的功效。 【EN】The invention discloses foam concrete and a method for repairing pavement subsidence by adopting the same, wherein the foam concrete comprises the following raw materials in parts by weight: 40-70 parts of cement, 10-30 parts of copper tailing powder, 10-20 parts of stone powder, 1-5 parts of an additive, 1-12 parts of a foaming agent and 15-35 parts of water. When the concrete pavement is used for settlement repair, the foam concrete is injected to a part to be repaired in a pressure injection mode, the foam concrete has similar performance to the original roadbed filler, the compatibility is good, the roadbed strength can be effectively improved after treatment, and the phenomenon of uneven settlement caused by concentrated load due to large difference between the front material and the rear material is reduced; and the pressure injection type process can support the settled pavement surface layer by means of filling pressure, so that the effect of self-adaptively recovering the settled surface layer is achieved.
