地下室工程畢業(yè)論文

摘     要
隨著城市化進(jìn)程的加快,城市建設(shè)的地下室越來越大,越來越深,這是城市建筑大型化、高層化以及充分利用地下室空間帶來的結(jié)果,然而地下室屬于隱蔽工程,如果在今后使用過程中出現(xiàn)漏水現(xiàn)象,后果將不堪設(shè)想,因而地下室的防水工程就顯得尤為重要和突出。
雖然造成滲漏的原因有很多種，但其中比較重要的有這幾種：設(shè)計、施工以及混凝土受溫度等原因造成的變形裂縫等主要方面。本方案主要研究地下室以及在對地下室施工過程中所常見的問題，例如地下室墻體產(chǎn)生裂縫，地下室發(fā)生滲漏，地下室超長混凝土結(jié)構(gòu)施工中如何防止混凝土產(chǎn)生裂縫和混凝土的變形等等。經(jīng)過研究本方案提出了如下解決辦法： 設(shè)置后澆帶。設(shè)置后澆帶是為了釋放變形產(chǎn)生的約束應(yīng)力，所以是目前運(yùn)用比較廣泛的防止溫度收縮變形產(chǎn)生裂縫的一種方法，并且是擴(kuò)大伸縮縫間距或者取消伸縮縫的有效措施；提高混凝土的抗?jié)B能力。在混凝土中添加摻量為0.6～0.8kg/m3的聚丙烯纖維，有效地抑制混凝土早期干縮微裂及離析裂紋的產(chǎn)生及發(fā)展，極大減少混凝土的收縮裂縫，尤其是有效抑制了連通裂縫的產(chǎn)生；均勻分布在混凝土中彼此相粘連的大量纖維起著“承托”骨料的作用，降低了混凝土表面的析水與骨料的離析，從而使混凝土中的孔隙含量大大降低，可以極大地提高抗?jié)B能力。

ABSTRACT
Along with urbanized advancement quickening, the urban construction basement is more and more big, more and more deep, this is the city construction large scale, the high stratification as well as fully the result which brings using the basement space, however the basement belongs to the concealed work, if will appear the water leakage phenomenon in the next use process, the consequence will be inconceivable, thus the basement waterproof project will appear especially is important and is prominent.
Although creates the leakage the reason to have very many kinds, but quite important has these kinds: The design, the construction as well as the concrete the strain crack which reasons and so on temperature is created and so on the principal aspect.Do this plan main research basements as well as in to the basement construction process in the common question, for example the basement wall produce the crack, the basement have the leakage, how in the basement ultra long concrete structure construction prevented the coagulation local product seams with concrete distortion and so on.After studied this plan to propose the following solution: 1 establishment the pouring belt.
  establishment the pouring belt is in order to release the restraint stress which the distortion produces, therefore is at present utilizes quite widely prevented the temperature shrinkage strain has the crack one method, and is expands the expansion joint spacing or cancels the expansion joint the effective action. 2  enhances the concrete impervious ability to increase in the concrete mixes the quantity is the 0.6~0.8kg/m3 polypropylene textile fiber, suppresses the concrete early time air shrinkage checking and the segregation crack production and the development effectively, reduces the concrete enormously the contraction crack, effectively has suppressed the connect crack production in particular; The uniform distribution each other adhesion massive textile fibers plays in the concrete;is supporting; the aggregate role, reduced the concrete surface bleeding and the aggregate segregation, thus causes in the concrete the void content to reduce greatly, may sharpen the impervious ability enormously.
Keywords：Basement ， waterproof， crack
