Description

一种既有建筑物注浆加固抬升智能监控方法、装置、系统及计算机可读存介质 技术领域
本申请涉及建筑物注浆加固抬升技术领域，尤其是涉及一种既有建筑物注浆加固抬升智能监控方法及系统。
背景技术
目前在发展中国家，由于地质勘察原因或建筑施工及管理的不规范、或在未保证工程质量和安全的情况下赶工期，建成的楼体容易出现下沉现象。
为了解决上述技术问题，应用于高层既有建筑结构的注浆加固纠偏方法应运而生，即通过注浆泵将注浆液通过注浆管注入到建筑物下方，以实现建筑物的加固抬升。当需要对建筑物进行加固抬升时，首先要选定多个注浆加固抬升点，通过多点注浆完成建筑物的加固纠偏。一般的，施工人员需要依据加固抬升现场的具体状况对加固抬升过程中多项细节进行调节，如数据的测量、注浆泵的调节、注浆液的调节、注浆管的钻孔深度、不同注浆加固抬升点的不同操作等等，以保证注浆加固抬升的施工质量。由于影响注浆加固抬升施工质量的因素有很多，同时每种因素的影响又存在各种各样的差别，导致难以实现施工现场的统一监测和管理。
发明内容
为了提高既有建筑物注浆加固抬升施工现场的自动化监控水平，本申请目的是提供一种既有建筑物注浆加固抬升智能监控方法、装置、系统及计算机可读存介质。
第一方面，本申请目的是提供一种既有建筑物注浆加固抬升智能监控方法，包括：

通过采用上述技术方案，建筑物注浆加固抬升一般都是多个点同时注浆，对建筑物多点同时抬升，同时每一加固抬升点都需要配置注浆管和多个注浆泵，这就需要考虑到多点抬升过程中每一点之间的注浆压力的平衡性问题、建筑物的整体抬升速率问题以及每一点的注浆加固抬升控制问题等等，从而造成加固抬升现场需要不同人员对不同的数据进行采集并分析的现象，不同人员之间的沟通与计算造成了加固抬升现场各方面控制的延迟或误差，严重影响了建筑物加固抬升的质量和安全性。本方案中，通过实时的采集高度和注浆压力数据，实现了对加固抬升现场各种注浆泵的自动化智能控制，极大的简化了加固抬升现场的控制复杂性以及迟滞性，助力建筑物注浆加固抬升的高安全及高质量施工。

具体实施方式
以下结合附图对本申请作进一步详细说明。
本具体实施例仅仅是对本申请的解释，其并不是对本申请的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本申请的权利要求范围内都受到专利法的保护。
参照图1，建筑工程注浆是指用适当的方法将某些能固化的浆液注入岩土地基中，通过置换、填充、挤压等方式以改善其物理力学性质的方法。建筑物注浆加固抬升是指在建筑物四周预先设定的多个注浆加固抬升点对建筑物进行注浆加固抬升。对于不同的建筑物来说，其预先设定的注浆加固抬升点均有不同，但是在同一加固抬升工程中，每一加固抬升点的加固抬升需保持同步，应避免某一或某一区域的加固抬升点对建筑物的支持力过大。本申请提供的注浆加固抬升智能监控方法及系统是为了在既有建筑物注浆加固抬升过程中实现对加固抬升过程数据的检测以及进一步的对注浆速度的自动化智能调节。
实施例一：
参照图2，实施例所述的建筑物注浆加固抬升是采用注浆泵2将注浆池中的注浆液通过注浆管1注入到指定的加固抬升点下方，注入到加固抬升点下方的注浆液凝固后起到对建筑物的支撑作用。本实施例中的注浆液为单浆液或双浆液，优选为双浆液，双浆液的组成至少包括水泥和水玻璃，施工现场可依据地质状况添加一些其余原料以改变双浆液本身的特性，在此不做唯一限定；注浆池作为料源3，是用于暂存注浆液原料的存储结构，且一般配置有搅拌装置，以实现对注浆池中浆液的搅拌，防止浆液凝固，由于具有该功能的存储结构已为现有技术中常规的设计，故在本申请中对注浆池的具体结构不做唯一限定，只要能够暂存液态的注浆液即在本实施例的说明范围内。注浆池，即料源3的数量与注浆液的原料数量对应。本实施例中，抬升点与注浆孔和注浆管1一一对应。
参照图2和图3，基于既有建筑物的注浆过程，本实施例提供一种注浆加固抬升智能监控方法，发方法为针对建筑物整体加固抬升的实时监控方法。具体包括：
获取注浆加固抬升过程中各加固抬升点的高度以及注浆压力数据；
依据所述高度计算所述建筑物的抬升高度变化速度；
若所述高度处在减小趋势下，则向注浆泵2输出停止信号，使得注浆泵2停止工作；
若所述高度处在上升趋势下，且所述高度低于预设高度，则依据所述高度、抬升高度变化速度和注浆压力数据向注浆泵2输出速度调节信号以改变注入注浆液的速度，和/或依 据所述高度、高度变化速度及注浆压力数据向注浆泵2输出配比调节信号以改变注浆液配比，从而改变注浆液的凝固速度；
若所述高度的数值等于或大于所述预设高度，则向注浆泵2输出停止信号，使得注浆泵2停止工作。
通过实时的采集高度和各加固抬升点的注浆压力数据，实现了对加固抬升现场各加固抬升点位置的注浆泵2的自动化智能控制，极大的简化了加固抬升现场的检测和控制的复杂性以及迟滞性。
获得加固抬升点高度的方法包括但不限定于人工测定和自动获取。人工测定的过程一般为工人依据水平高度测量工具，如水平仪等，测量加固抬升点的实时高度，然后将测量出的高度进行人工录入；自动获取的过程一般为通过自动化的定位实现对加固抬升点的实时高度测量。本实施例中采用自动获取的方式测量加固抬升点的水平高度，具体的，在每一加固抬升点固定安装北斗监测站，采用北斗定位技术实现对北斗监测站的高度测量，进而实现对每一加固抬升点的高度测量，从而获得加固抬升点的高度。需要理解的是，由于建筑物为一整体结构，一般的，建筑物注浆加固抬升过程中，其本身结构不会发生变化，故在另外一个示例中，也可以通过直接测定建筑物的高度，进而通过建筑物的高度计算每一加固抬升点的高度。如对于筏板基础为矩形的建筑物来说，其高度可以是建筑物四个角的高度，进而通过建筑物四个角的高度计算出每一个加固抬升点的高度。
注浆压力数据可以是直接采集注浆泵2上的压力表数据获得。
注浆加固抬升过程包括多个注浆阶段，每一注浆阶段均包括注浆时段和稳定时段，注浆时段内向注浆孔内注浆，稳定时段内停止注浆。在开始注浆阶段，由于注入注浆孔的注浆液与注浆位置的土层相互作用，会有注浆时段加固抬升点高度下降的状况发生，即高度处在减小趋势，一般这种状况发生后会引发安全隐患，并不适合再进行自动化的注浆调节，此时向注浆泵2输出停止信号，使得注浆泵2停止工作，之后再转由现场工作人员对注浆泵2、注浆液或注浆孔位置做人工的调节，以确保注浆加固抬升过程的安全。
参照图3和图4，在经过开始的注浆阶段后，再次注浆，则在注浆时段内，加固抬升点的高度将处在上升趋势，通过改变注浆泵2的输出功率以改变注浆时段的注浆速度，改变注浆泵2输出功率所依据的速度调节信号包括有速度增加信号和速度减小信号。
在一个示例中，如果建筑物的抬升高度变化速度大于预设加固抬升速度的最大值，说明建筑物抬升的速度超过了预设的速度，向注浆泵2同步输出速度减小信号，以同步降低注浆泵2的输出功率，即同步降低注浆泵2输送注浆液的速度；如果高度变化速度小于预设加固抬升速度的最小值，说明建筑物抬升速度低于预设的速度，向注浆泵2同步输出速 度增加信号，以同步提高注浆泵2的输出功率，即同步增加注浆泵2输送浆液的速度。本示例表达的“同步”是指对注浆泵2的如下调节方式：在建筑物抬升过程中，位于不同加固抬升点的注浆泵2注入的浆液，能够填补因建筑物抬升而留出的地基空缺。如加固抬升过程中包含的三个加固抬升点为等间距且共线的A、B和C，加固抬升过程中A点高度不变，B点抬高h，C点抬高2h，则同步增加的B点和C点的注浆泵2输送浆液的速度分别为v和2v，以使得B点和C点因增加注浆泵2功率而多注入的注浆液量的比值为1/2。故此，当加固抬升点设定好之后，则同步改变注浆泵2注浆速度时，如选定其中一个加固抬升点为基点，则另外的加固抬升点的速度变化因子都将是一个可以计算的值，即每一个加固抬升点都会有同步加固抬升建筑物过程中的一个已知的变化因子。
预设加固抬升速度的最大值与预设加固抬升速度的最小值组成预设加固抬升速度的范围，且预设加固抬升速度的最大值不小于预设加固抬升速度的最小值；预设加固抬升速度的范围为依据建筑物所处实地状况预先测算得出。
将加固抬升点的注浆压力数值与相应加固抬升点的标准注浆压力数值进行比较，依据比较结果以及相应加固抬升点的变化因子改变注浆泵2的输出功率，通过改变注浆泵2的输出功率以改变注浆时段的注浆速度，改变注浆泵2输出功率所依据的速度调节信号同样包括在速度增加信号和速度减小信号内。
其中，标准注浆压力数值为依据每一注浆加固抬升点的高度、抬升点高度变化速度数值以及注浆压力数据数值实时计算得到。其中，在注浆加固抬升过程中，建筑物抬升到一定高度后，加固抬升点所需要施加给建筑物的支撑力一般是通过高度和抬升点高度变化速度查表获得，这个查表所获得的数据为标准数据，但是注浆液对建筑物的抬升都会受到地底土壤应力、组成和结构的影响，当注浆压力数据的数值与查表所获得的标准数据相差过大时，如果直接将注浆泵2注浆的压力变更到标准数据，会使因为注浆压力短时间的过大突变导致后期的加固抬升反复变化，故在本申请实施例中，标准注浆压力数值为单独计算得出，不会直接将标准数据直接赋值给标准注浆压力数值。
具体的，标准注浆压力数据采用以下方式计算：
Fv＝Fn-k*(Fn-Fc)，其中：Fv为标准注浆压力，Fn为标准数据，Fc为采集到的注浆压力，k为常数且小于1。
在一个优选的示例中，注浆泵2输出功率的数值改变的大小与注浆压力数据的数值和标准注浆压力数值的差值符合二值曲线变化规律，其变化关系为一个预存的速度调节变化曲线，从而依据变化曲线以及注浆压力数据的数值和标准注浆压力数值的差值计算得到最终的速度增加信号或速度减小信号。当加固抬升点的注浆压力数值小于所述标准注浆压力 数值时，说明相应加固抬升点对建筑物的支撑力度小，向注浆泵2输出速度增加信号以提高注浆泵2注入注浆液的速度，从而提高加固抬升点对建筑物的支撑力度；当加固抬升点的注浆压力数值大于所述标准注浆压力数值时，说明相应加固抬升点对建筑物的支撑力度过大，则向注浆泵2输出速度减小信号以降低注浆泵2注入注浆液的速度，从而降低加固抬升点对建筑物的支撑力度。
在另一个示例中，注浆泵2的输出功率预设有多个不同的呈线性变化的值，在依据速度增加信号或速度减小信号调节注浆泵2的输出功率的方式为给定注浆泵2的功率在不同值之间跳变，且以高度变化速度的变化速率以及注浆压力数据的数值和标准注浆压力数值的差值为设定跳变大小的依据。如注浆泵2的输出功率由小到大依次为η1、η2、η3…ηn，注浆泵22的起始功率为ηk，则在高度变化速度大于预设加固抬升速度的最小值和/或加固抬升点的注浆压力数值大于所述标准注浆压力数值时，可依据高度变化速度与预设加固抬升速度的差值以及加固抬升点的注浆压力数值与所述标准注浆压力数值的差值给定注浆泵2输出功率为ηk-1、ηk-2或ηk-5等，此处的n和k均为自然数。
高度的数值等于或大于预设高度，则向注浆泵2输出停止信号。此处所述的预设高度包括预设阶段高度和预设最终高度，预设阶段高度和预设最终高度分别对应单个注浆阶段内建筑物抬升的目标高度，和整体加固抬升工程的建筑物抬升目标高度。在单个注浆阶段的注浆时段内，若高度的数值等于或大于预设阶段高度，则说明单个注浆阶段内注浆过程中，建筑物的高度超标，此时，向注浆泵2输出停止信号，以使得注浆泵2停止工作；若高度的数值大于预设最终高度，则向注浆泵2输入停止信号，且在输出停止信号后的预设监测时间内高度下降幅度超出预设稳定范围，则控制模块向注浆泵2输出启动信号，再次启动注浆，直至预设监测时间内高度下降幅度位于预设稳定范围内。
参照图5，本申请还提供一种既有建筑物注浆加固抬升智能监控装置，该系统包括：
数据获取模块，用于获取注浆加固抬升过程中各加固抬升点的高度以及注浆压力数据；
变化速度计算模块，用于依据所述高度计算所述建筑物的抬升高度变化速度；
以及控制模块，用于

在所述高度的数值等于或大于所述预设高度时，向注浆泵2输出停止信号，使得注浆泵2停止工作。
控制模块依据高度、抬升高度变化速度和注浆压力数据向注浆泵2输出速度调节信号以改变注浆泵2注入浆液的速度的方式，可参照上述的既有建筑物注浆加固抬升智能监控方法，在此不再赘述。
在注浆加固抬升过程中通过在加固抬升点固定安装北斗监测站，以实现通过北斗定位技术实时测量加固抬升点的高度，通过读取注浆泵2的压力表数据，实时获取所述的注浆压力数据。
优选的，数据获取模块、变化速度计算模块和控制模块集成于一个具有集成控制功能的中央控制器中，如电脑、工控机等。中央控制器通过有线或无线的方式连接附加设备和云数据库，附加设备至少包括移动手机和报警装置，当然，具备移动通信功能、电子显示和数据处理功能的电子设备均可作为附加设备，本实施例描述的移动手机并非对附加设备的唯一限定。在一个优选的示例中，中央控制器通过4G网络连接移动手机，并通过现场总线的有线连接方式连接报警装置。
一方面，中央控制器通过北斗定位网络获取北斗监测站检测到的高度；另一方面，工作人员可通过附加设备获取到中央控制器接收到的高度、注浆压力数据以及高度变化速度等数据，并通过附加设备变更中央控制器实施既有建筑物注浆加固抬升智能监控方法过程中应用到的预设加固抬升速度的范围、预设高度、变化曲线等预设数据的数值。
在高度处在减小趋势下的状况，以及所述高度的数值等于或大于所述预设高度的状况中的任意一种状况存在时，中央控制器同时向移动手机和报警装置输出报警驱动信号，以通过移动手机和报警装置报警。报警装置中产生报警信号的报警器件优选为蜂鸣器。
通过以上描述可以获知：在建筑物注浆加固抬升过程中，由于通过中央控制器自动采集了高度以及每个加固抬升点的注浆压力数据，并自动计算和控制每一加固抬升点的注浆泵2的注浆速度，实现了整个注浆加固抬升过程中的自动化监控，不但提高了注浆加固抬升工程的自动化性能，同时极大的简化了加固抬升现场的控制复杂性以及迟滞性，助力建筑物注浆加固抬升的高安全及高质量施工。

实施例二：
本实施例与实施例一的区别之处在于，本实施例所述的建筑物注浆加固抬升过程中，是通过调节注浆液的凝固速度调节每一加固抬升点对建筑物的支撑力度或整体调节建筑物的加固抬升速度。
以下仅以既有建筑物注浆加固抬升智能监控方法的角度描述本实施例与实施例一之间的不同。
参照图6，若高度处在上升趋势下，且高度低于预设高度，依据所述高度、高 度变化速度及注浆压力数据向注浆泵2输出配比调节信号以改变注浆液配比，从而改变注浆液的凝固速度。若所述高度的数值等于或大于所述预设高度，则向注浆泵2输出停止信号，使得注浆泵2停止工作。
优选的，每一加固抬升点均设置有一个注浆管1，每一注浆管1连接有多种料源，每一料源与注浆管1之间均通过注浆泵2连接，料源内的浆液在进入注浆管1后，在注浆管1内部混合形成注浆液。通过调节注浆泵2的输出功率即可调节注浆液的配比，从而改变注浆液的凝固速度。
在经过开始的注浆阶段后，再次注浆，则在注浆时段内，高度将处在上升趋势，在不改变注浆泵2注浆速度的前提下，通过改变注浆液的水灰比改变注浆液的凝固速度。
若抬升高度变化速度大于预设加固抬升速度的最大值，则向注浆泵2输出水灰比降低信号，以同步降低注浆液的凝固速度；若所述抬升高度变化速度小于预设加固抬升速度的最小值，则向注浆泵2同步输出水灰比提高信号，以同步提高注浆液的凝固速度。
将加固抬升点的注浆压力数值与相应加固抬升点的标准注浆压力数值进行比较，依据比较结果以及相应加固抬升点的变化因子改变注浆液的配比，通过改变注浆液的配比以改变注浆时段加固抬升点对建筑物的支撑力度，改变注浆液配比所依据的配比调节信号同样包括在速度增加信号和速度减小信号内。
其中，配比调节信号包括水灰比提高信号和水灰比降低信号。若所述加固抬升点的注浆压力数值小于所述标准注浆压力数值，则向注浆泵2输出水灰比提高信号，以提高注浆液的凝固速度；若所述加固抬升点的注浆压力数值大于所述标准注浆压力数值，则向注浆泵2输出水灰比降低信号，以降低注浆液的凝固速度。
在一个优选的示例中，水灰比提高信号和水灰比降低信号的数值与所述注浆压力数值和标准注浆压力数值的差值符合二值曲线变化规律，其变化关系为一个预存的水灰比变化曲线，从而依据变化曲线以及注浆压力数据的数值和标准注浆压力数值的差值计算得到最终的水灰比提高信号或水灰比降低信号。
本实施例所提供的既有建筑物注浆加固抬升智能监控装置中，控制模块依据高度、抬升高度变化速度和注浆压力数据输出配比调节信号以调节注浆液的凝固速度的方式，可参照本实施例中的既有建筑物注浆加固抬升智能监控方法，在此不再赘述。
通过以上描述可以获知：在建筑物注浆加固抬升过程中，由于通过中央控制器自动采集了高度以及每个加固抬升点的注浆压力数据，并自动计算和控制每一加固抬升点注浆液的凝固速度，实现了整个注浆加固抬升过程中的自动化监控，不但提高了注浆加固抬升工程的自动化性能，同时极大的简化了加固抬升现场的控制复杂性以及迟滞性，助力建筑物 注浆加固抬升的高安全及高质量施工。
实施例三：
以既有建筑物注浆加固抬升智能监控方法的角度描述本实施例与实施例一和实施例二的不同：在注浆阶段，若高度处在上升趋势下，且高度低于预设高度，依据高度、抬升高度变化速度和注浆压力数据向注浆泵2输出速度调节信号以及配比调节信号，以改变每一注浆泵2的输出功率。
若抬升高度变化速度大于预设加固抬升速度的最大值，则向注浆泵2同步输出速度减小信号以同步降低注浆泵2注入注浆液的速度，并向注浆泵2输出水灰比降低信号，以同步降低注浆液的凝固速度；若所述抬升高度变化速度小于预设加固抬升速度的最小值，则向注浆泵2同步输出速度增加信号以同步提高注浆泵2注入注浆液的速度，并向注浆泵2输出水灰比提高信号，以同步提高注浆液的凝固速度。
以上具体实施方式的实施例均为本申请的较佳实施例，并非依此限制本申请的保护范围，故：凡依本申请的结构、形状、原理所做的等效变化，均应涵盖于本申请的保护范围之内。
