Description

一种用于拼装井身墙体的预制砌块 技术领域
本发明涉及一种井，特别涉及一种用于拼装井身墙体的预制砌块。本发明为修筑地下构筑物井身墙体的砌筑构件。本发明属于建筑材料制造加工技术领域。
背景技术
在建筑材料领域，地下构筑物检查井等各种井的井身截面有矩形、方形、圆弧形状等多种形状，但目前普遍采用的井身截面形状是圆弧形，即形成井身的内壁和外壁为圆柱体井身。井身最初是采用砖块修砌，但这种砖块修砌的井身存在着井体强度低、抗渗漏性差、需要粉刷、易脱皮、修砌时间长等缺陷，特别是操作人员在修砌和粉刷井身时存在着很大的安全问题，因而逐渐被圆弧形的预制砌块所取代，预制砌块一般由混凝土制作而成，多块预制砌块的配合安装组成一层圆柱体井身，然后通过上下相邻层的预制砌块将井身修砌拼装起来，形成具有一定深度的具有内外圆弧面的、整体为圆柱体的井身。在预制砌块的加强连筋两侧具有预留孔，预留孔为可灌装混凝土等的通孔，在修砌拼装预制砌块时，每当拼装一定层数后，就需在预留孔内及各空隙处灌装混凝土等，并通过机器对灌装进预制砌块预留孔内及各空隙处的混凝土等进行震动捣实形成密实的填充体，从而使预制砌块拼装成的井身墙体更加牢靠。现有用于拼装井身墙体的预制砌块品种繁多。
公开号为CN1431375A的中国发明专利申请公开了一种“井壁墙体模块以及采用该模块构筑井壁墙体的方法”。该发明申请所述的模块通过设置在所述模块表面上的凹凸结构来实现所述模块在砌筑过程中相互对齐和卡紧，并通过向在所述模块上预留的孔、槽中浇注混凝土浆料和/或插入加强来将所述井壁墙体构筑成具有不同承载性能的整体，来提高所述井壁墙体的强度。
公开号为CN101748846A的中国发明专利申请公开了一种“井壁墙体模块”。该发明申请的包括同轴圆弧形的前模板和后模板以及第一肋和第二肋，中部有通孔，两端有半孔。模块连接时，相邻模块端部的半孔形成拼接孔。通孔和拼接孔的两个竖直侧面之间的圆心夹角相等。通过优化模块的尺度关系，使前模板和后模板突出第一肋和第二肋的部分不至于延长，避免模板断裂和损伤现象。采用该模块压缝构筑墙体时，同一层上相邻模块端部的拼接孔与相邻模块中部的通孔形成形状和尺寸均匀的浇注孔，浇入其中的混凝土在浇注孔内形成形状和尺寸均匀的强度构件，使墙体强度均匀。
公开号为CN19994361A的中国发明专利申请公开了“一种井身预制砌块”。该发明申请包括有圆弧形内筒壁和圆弧形外筒壁，圆弧形内筒壁和圆弧形外筒壁之间设置有加强连筋，圆弧形内筒壁上表面的内侧和圆弧形外筒壁上表面的内侧均具有凹槽，圆弧形内筒壁下表面的内侧和圆弧形外筒壁下表面的内侧均具有与凹槽相匹配的凸起，加强连筋的上端面低于圆弧形内筒壁的上表面，加强连筋的下端面低于圆弧形内筒壁的下表面。
上述公开号为CN1431375A的中国发明专利申请的目的在于提供一种施工便捷的模块，模块轻便、便于搬运和安装，后由该种模块拼装的井壁墙体牢固。上述公开号为CN101748846A的中国发明专利申请的目的在于通过改进和优化井壁墙体模块结构和尺寸关系，提供避免在模板端部断裂和操作的井壁墙体模块，使采用该种模块构筑井壁墙体时，浇注在墙体内部的混凝土或者灰浆能形成密实的填充体，使墙体强度均匀。公开号为CN19994361A的中国发明专利申请的目的在于提供不渗漏、强度高、具有足够浇注空隙、修砌质量好、安装操作方便的一种井身预制砌块。
上述公开的中国专利申请及现有的各种用于拼装井身墙体的预制砌块，其主旨是使预制砌块的结构更加合理，从而使模块既轻便、便于搬运和安装，又能保证良好的强度，一方面是模块的拼装端部等处不易断裂，且预制砌块整体强度好，另一方面预制砌块构筑拼装后的井身墙体的强度好，填充的混凝土等填充体紧实，不出现渗漏等。但是现有技术的用于拼装井身墙体的预制砌块都还存在着严重的缺陷，根本无法从根本上解决上述这些问题。其严重缺陷如下：（1）结构不合理，在修砌拼装预制砌块时，每当拼装一定层数后向预留孔内及各空隙处灌装混凝土等，并通过机器对灌装进预制砌块预留孔内及各空隙处的混凝土等进行震动捣实时，都存在着严重的跑浆现象，跑浆造成现有的预制砌块拼装构筑的井身墙体内根本无法形成密实的填充体，内部出现空洞，填充均匀性差，使预制砌块拼装成的井身墙体的牢固强度和防渗漏能力无法得到根本性的改善。在公开号为CN19994361A的中国发明专利申请中所述在混凝土浇注和进行震实的过程中不会从砌块之间缝隙中跑漏出来，不会出现跑浆、漏浆现象，但该砌块由于结构上为台阶式直角结构，且砌块宽度减半，因此在生产、运输、施工过程中十分容易破损、缺角，破损、缺角后又无法修补，使预想达到的防跑浆功能大打折扣，而这一缺陷又无法用增大砌块宽度的方式解决，因此该专利申请的结构也不能从根本上解决跑浆的问题。避免跑浆现象的发生一直是人们急需解决，但却一直无法解决的技术难题。（2）由于跑浆严重，大量混凝土或灰浆等浆液的外泄，影响井身墙体的牢固强度以及出现渗漏。
 技术问题
本发明的目的是针对上述技术中存在的不足，提供一种结构合理简单、强度高、不渗漏、具有足够浇注空隙、轻便、且能解决制作井身墙体过程中跑浆这一根本问题的一种用于拼装井身墙体的预制砌块。
技术解决方案
一种用于拼装井身墙体的预制砌块，砌块为具有上表面、下表面、左侧表面、右侧表面、内圆弧面和外圆弧面的圆弧形砌块，圆弧形砌块包括有同轴的圆弧形内筒壁和圆弧形外筒壁，还包括有设置在圆弧形内筒壁和圆弧形外筒壁之间并将二者连接起来的加强连筋，加强连筋左右两侧具有预留孔。所述圆弧形砌块的上表面上开有上止水槽，下表面上开有下止水槽，圆弧形内筒壁上表面上的上止水槽与圆弧形内筒壁下表面上的下止水槽相匹配，圆弧形外筒壁上表面上的上止水槽与圆弧形外筒壁下表面上的下止水槽相匹配。
进一步，所述上表面的上止水槽内嵌装有与上止水槽相匹配的止水带，止水带上部露出上止水槽的上沿。
进一步，所述圆弧形外筒壁上表面上的上止水槽外侧上沿至圆弧形外筒壁上表面的外沿为水平直面，圆弧形外筒壁上表面上的上止水槽内侧上沿至圆弧形外筒壁上表面的中间侧上沿为斜坡直面或者为中间水平直面和斜坡直面形成的组合面；且圆弧形内筒壁上表面、圆弧形内筒壁下表面和圆弧形外筒壁下表面三者均与圆弧形外筒壁上表面具有相同的表面形状。
进一步，所述圆弧形砌块的左侧表面上具有凸起部，圆弧形砌块的右侧表面上具有与凸起部互相匹配插接形成圆柱形井身的凹陷部。
进一步，所述圆弧形内筒壁上表面、圆弧形外筒壁上表面、圆弧形内筒壁下表面或圆弧形外筒壁下表面四者的表面宽度相等，且该表面宽度等于圆弧形砌块的总厚度的1/4～1/3。
进一步，所述圆弧形砌块的总厚度为180mm～250mm，圆弧形砌块的总高度为150 mm～250mm，加强连筋最薄处的高度为圆弧形砌块的总高度的1/2～2/3，加强连筋左右两垂直面之间的最小水平距离为50mm～70mm。
进一步，所述上表面的上止水槽的深度为10mm～15mm，下表面的下止水槽的深度为10mm～20mm，所述上止水槽和下止水槽的宽度相等，且宽度均为3 mm～5mm。
更进一步，所述止水带采用制作材料为塑料、铁板或橡胶。
更进一步，所述圆弧形外筒壁上表面、圆弧形内筒壁上表面、圆弧形内筒壁下表面和圆弧形外筒壁下表面四者的水平直面的直面宽度均相等，水平直面的直面宽度等于圆弧形外筒壁上表面表面宽度的1/2～1/3。
更进一步，所述斜坡直面的坡角为小于20°。
 有益效果
本发明在所述上表面上开有上止水槽，下表面上开有下止水槽，圆弧形内筒壁上表面上的上止水槽与圆弧形内筒壁下表面上的下止水槽相匹配，即圆弧形内筒壁上表面上的上止水槽与圆弧形内筒壁下表面上的下止水槽在垂直方向上的投影相重合，二者具有相同的圆弧形、相同的槽宽和上下相应的相同位置。圆弧形外筒壁上表面上的上止水槽与圆弧形外筒壁下表面上的下止水槽相匹配，即圆弧形外筒壁上表面上的上止水槽与圆弧形外筒壁下表面上的下止水槽在垂直方向上的投影相重合，二者具有相同的圆弧形、相同的槽宽和上下相应的相同位置。本发明结构合理简单，设计巧妙，通过圆弧形砌块的上表面上开有的上止水槽和下表面上开有的下止水槽的设置，一改现有传统砌块的结构，做了突破性的改进创新，在使用本发明拼装构筑井身墙体时，在上止水槽内嵌装与上止水槽相匹配的止水带，止水带上部露出上止水槽的上沿，露出上止水槽上沿的止水带上部则嵌装在上面相邻层圆弧形砌块的下表面的下止水槽内。本发明的这种结构具有超强止浆功能，有效防止跑浆现象的发生。在修砌拼装预制砌块时，当通过机器对灌装进预制砌块预留孔内及各空隙处的混凝土等进行震动捣实时，不会出现跑浆现象，因此拼装的井身墙体内形成密实的填充体，内部不会出现空洞等缺陷，填充体均匀统一，使预制砌块拼装成的井身墙体的牢固强度高，防渗漏能力得到根本性的改善。本发明用这一合理简单、但十分巧妙的结构解决了人们急需解决，但却一直无法解决的技术难题。本发明强度高，不渗漏，具有足够浇注空隙，轻便，且解决了制作井身墙体过程中跑浆这一根本问题。
由于本发明解决了跑浆问题，避免了混凝土或灰浆等浆液的外泄现象，因此修砌好的井身墙体的牢固强度高，不会出现渗水现象。
本发明上止水槽和下止槽的设置还具有定位的作用，使得本发明拼装使用时通过上止水槽和下止槽定位即可用止水带迅速安装上面相邻层圆弧形砌块。本发明定位效果好，定位准确，安装快捷方便，使相邻层圆弧形砌块之间固定的牢固度也进一步得以加强。

本发明所述止水带10优选塑料、铁板或橡胶材料制作。所述圆弧形外筒壁上表面1-1-2、圆弧形内筒壁上表面1-1-1、圆弧形内筒壁下表面1-2-1和圆弧形外筒壁下表面1-2-2四者的水平直面的直面宽度均相等，水平直面的直面宽度等于圆弧形外筒壁上表面1-1-2表面宽度的1/2～1/3为优选。而且其中所述斜坡直面的坡角α优选为小于20°。所述圆弧形内筒壁上表面1-1-1、圆弧形外筒壁上表面1-1-2、圆弧形内筒壁下表面1-2-1或圆弧形外筒壁下表面1-2-2四者的表面宽度M相等，且该表面宽度M等于圆弧形砌块1的总厚度L的1/4～1/3为优选。所述圆弧形砌块1的总厚度L优选180mm～250mm，圆弧形砌块1的总高度H优选150mm～250 mm，加强连筋4最薄处的高度H3优选为圆弧形砌块1的总高度H的1/2～2/3，加强连筋4左右两垂直面之间的最小水平距离优选为50mm～70mm。所述上表面1-1的上止水槽8的深度H1优选10mm～15mm，下表面1-2的下止水槽9的深度H2优选10mm～20mm，所述上止水槽8和下止水槽9的宽度N1均优选3 mm～5mm。所述止水带10的厚度小于上止水槽8、下止水槽9的宽度N1，止水带10的厚度优选为2 mm～3.5mm。本发明斜坡直面的坡角α的设置，使得本发明拼装后上下相邻层圆弧形砌块1之间形成的填充空隙在止水带10内侧处为两坡面围成的填充空隙，这样便于机器震动捣实混凝土等浆液，使在这一处关键的填充空隙处震动捣实混凝土等浆液的效果非常好。防止出现跑浆、漏浆等现象，增加井身墙体的牢固强度，使本发明达到更加理想的最佳状态。
本发明使用时，参见图7，O点为井身墙体的圆心。每块圆弧形砌块1的左侧表面1-3上具有的凸起部6与侧面相邻一块圆弧形砌块1右侧表面1-4上的凹陷部7互相匹配插接形成一层圆柱形井身墙体，每层圆柱形井身墙体依靠上止水槽8和下止水槽9处的止水带10进行上下相邻层的连接，形成整体井身墙体。安装时，相邻层的接缝错开，使本发明修砌拼装的圆柱形井身的纵向接缝全部交错开，各层之间不易发生错动、胀开和渗漏。
本发明设置规格为：拼装圆柱体井身墙体的内径为φ700mm（即圆弧形内筒壁2的半径为R350mm）、φ900mm（即圆弧形内筒壁2的半径为R450mm）、φ1100mm（即圆弧形内筒壁2的半径为R550mm）、φ1300mm（即圆弧形内筒壁2的半径为R650mm）、φ1500mm（即圆弧形内筒壁2的半径为R750mm），拼装成上述五种规格的井身墙体相对应使用的预制砌块块数分别为7块、9块、11块、13块、15块（即由本发明7块圆弧形砌块1拼装成内径为φ700mm的井身墙体，由本发明9块圆弧形砌块1拼装成内径为φ900mm的井身墙体，由本发明11块圆弧形砌块1拼装成内径为φ1100mm的井身墙体，由本发明13块圆弧形砌块1拼装成内径为φ1300mm的井身墙体，由本发明15块圆弧形砌块1拼装成内径为φ1500mm的井身墙体）。
本发明不限于上述实施例，凡采用等同替换或等效替换形成的技术方案均属于本发明要求保护的范围。
