Ultrahigh pressure water jet precast slab ballast bed self-compacting concrete crushing method
The invention relates to the technical field of urban rail transit engineering, in particular to an ultrahigh-pressure water jet precast slab ballast bed self-compacting concrete crushing method which comprises a high-pressure water pump, a handheld water gun and a water tank. The crushing method specifically comprises the following steps: S1, pressurizing water by adopting an ultrahigh-pressure pump to achieve the pressure for breaking concrete; s2, forcible entry parameters are controlled through a control mechanism for forcible entry; s3, selective and accurate forcible entry is carried out according to the concrete disease position; s4, detecting a forcible entry result: after the self-compacting concrete is crushed, detecting whether the forcible entry is qualified or not by utilizing a micro detection head; and S5, re-pouring is conducted, and when concrete is poured after forcible entry, concrete is injected from the precast slab ballast bed pouring holes. Compared with the prior art, the crusher has the advantage that the crushing depth and range can be accurately controlled. Dust and vibration are completely avoided in the hydraulic crushing process, the noise is low, used wastewater can be recycled and purified in time through a sewage treater, and environmental friendliness is achieved. And the rapid construction requirement is met.
本发明涉及城市轨道交通工程技术领域，具体来说是一种超高压水射流预制板道床自密实混凝土破碎方法，包括高压水泵、手持水枪和水箱所述破碎方法具体如下：S1.采用超高压泵对水进行增压，以达到破除混凝土的压力；S2.通过控制机构控制破拆参数进行破拆；S3.根据混凝土病害位置进行选择性精确破拆；S4.破拆结果检测，在对自密实混凝土破碎完成后，利用微型探测头检测破拆是否合格；S5.重新浇筑，破拆后浇筑混凝土时，采用混泥土从预制板道床浇筑孔注入。本发明同现有技术相比，其优点在于：可精确控制破碎的深度和范围。水力破碎过程中完全无粉尘、无振动、噪音小，使用后的废水可以通过污水处理器及时回收净化，绿色环保。符合快速化施工要求。
