300*4EVA塑料止水帶多少錢
可應用在任何地面或地下建筑，形成一道長久而堅固的隔水屏障，特別適用于儲水和擋水的結構，例如水庫、污水池、水壩、地鐵、隧道擋水墻等.
The utility model can be applied to any ground or underground building, forming a long and strong barrier for water storage, especially for the structure of water storage and water retaining, such as reservoirs, sewage pools, dams, subways, tunnel retaining walls, etc.
防水板采用空鋪法固定在噴射混凝土的基面上，防水板與后澆混凝土之間無法密貼。而防水板鋪設時很容易出現破損部位，一旦破損部位未發(fā)現并且進行修補，就會造成滲漏水進入防水板和二襯結構之間．在結構不密實或開裂部位滲出。產生竄水現象，給后期堵漏維修工作帶來很大困難．這就是防水板全包防水層的缺陷。為解決這一難題，就需要在防水層表面設置分區(qū)注漿系統(tǒng)。
The waterproof board is fixed on the base surface of the Shotcrete by the empty paving method, and the waterproof board and the post pouring concrete can not be densely pasted. The waterproof board laying easily damaged parts, once damaged parts were found and repaired, it will cause water leakage into the waterproof board and two lining structure. In the structure is dense or cracking site exudation. The phenomenon of water channeling brings great difficulties to the later plugging and maintenance work, which is the defect of the waterproof layer of the waterproof board. In order to solve this problem, it is necessary to set the district grouting system on the surface of waterproof layer.
分區(qū)系統(tǒng)是通過一定的手段，將防水區(qū)域分隔開，這樣如果個別區(qū)域內一旦出現滲漏，滲漏水不會竄入其它防水區(qū)域內，減少后期的注漿堵漏工作量。這樣的分區(qū)系統(tǒng)就靠背貼止水帶來實現。背貼式止水帶是防水板后的第一道防水層．對于隧道滲水的預防至關重要。為保證后灌注的混凝土與止水帶之間咬合密實．減少出現竄水的現象，需要在背貼式止水帶兩側的齒條間設置注漿花管，一旦出現不實現象可以通過注漿花管進行注漿。

The partition system is to separate the waterproof area through some means, so if there is leakage in the individual area, the leakage will not be channeling into other waterproof areas, so as to reduce the late grouting plugging work. This partition system enables the backrest to be watertight. The back waterproof belt is the first waterproof layer after the waterproof board, which is very important for the prevention of the tunnel seepage. In order to ensure the concrete and water perfusion zone between the occlusal density. To reduce the water channeling phenomenon, need to set the rack mounted in the sealing grouting back belt on both sides of the flower tube, once the false phenomenon by grouting pipe grouting.

Application range:
EVA背貼式止水帶作為防水板的輔材，可廣泛應用于地下室、地鐵隧道、公路和鐵路隧道工程的防水，水壩、人工湖、水池、污水處理場、垃圾掩埋場等工程的防水及防滲。另外， EVA背貼式止水帶也可單獨作為止水帶使用，應用于混凝土現澆時變形縫、施工縫內與混凝土結構成為一體的基礎工程中，決縫隙處的滲漏水問題。技術現象我公司可生產不同口型、不同規(guī)格尺寸．不同斷面的背貼式止水帶，不同材料的止水帶符合不同的標準。
EVA back stick type waterstop waterproof board as the auxiliary material, can be widely used in the basement, metro tunnel, highway and railway tunnel waterproofing, dams, artificial lakes, ponds, sewage treatment plant, landfill, waterproof and anti-seepage engineering. In addition, EVA back stick type waterstop can be used as sealing strip, applied to cast-in-place concrete deformation and construction joint and concrete structure has become one of the basic engineering, no crevice water leakage problem. Technical phenomenon, our company can produce different mouth shape, different sizes, different sections of back type water stop belt, different materials of water stop belt meet the different standards.
EVA塑料止水帶的施工方法及注意事項
Construction methods and matters needing attention of EVA plastic water stop belt
EVA塑料止水帶它由PVC聚氯乙烯樹脂及各種填加劑，經混合、造粒、擠出等工序而制成的止水材料。此產品利用彈性體材料具有的彈性變形特性在建筑構造接縫中起到防漏、防滲作用，并且具有耐腐蝕、耐久性好的特點。

EVA plastic water stop belt is made of PVC polyvinyl chloride resin and various filling agent. It is made up of mixing, granulating and extruding process. This product uses elastic deformation characteristics of elastomer material to play a role of leak prevention and seepage prevention in building structural joints, and has the characteristics of corrosion resistance and durability.
EVA塑料止水帶主要用于混凝土澆注時設置在施工縫及變形縫內與混凝土構成為一體的基礎工程。如隧道、涵洞、引水渡槽、攔水壩、貯液構筑物、地下設施等。PVC塑料止水帶施工方法與普通的橡膠止水帶相同。在澆埋時要使其與混凝土界面貼合平整，接頭部分粘接緊固，澆埋過程中要以適當的力充分震搗混凝土，使其與混凝土結合良好，以獲得最佳的止水效果。PVC塑料止水帶施工注意中要注意一些問題，由于混凝土中有許多尖角的石子和鋼筋，操作是要注意避免對止水帶造成機械損傷。在定位塑料止水帶時，要使其與混凝土界面貼合平整，不能出現止水帶翻轉、扭曲等現象，否則應及時進行調正在澆筑固定止水帶時，應防止止水帶發(fā)生偏移，影響止水效果。此種塑料止水帶接頭可利用粘接、熱焊接等方法，保證接頭牢固。澆注混凝土過程中要注意充分震搗，以達到止水帶和混凝土充分結合。
EVA plastic water stop belt is mainly used for concrete pouring, set up in the construction joints and deformation joints and concrete as one of the basic engineering. Such as tunnel, culvert, aqueduct, dam, reservoir structures, underground facilities, etc.. The construction method of PVC plastic water stop belt is the same as that of common rubber water stop belt. In the pouring buried to make it smooth and fit the concrete interface, the joint part of the adhesive fastening, pouring process to buried in an appropriate capacity of fully vibrating concrete, the good combination with concrete, in order to obtain the best sealing effect. PVC plastic water stop construction should pay attention to some problems, because there are many sharp stones and steel reinforcement in the concrete, the operation should pay attention to avoid mechanical damage to the water stop belt. In the positioning of the plastic waterstop, to make it smooth and fit the concrete interface, can not appear waterstop flip, twist phenomenon, otherwise should be timely adjusted is pouring fixed sealing strip, should prevent the waterstop shift, affecting sealing effect. The joint of the plastic water stop belt can be bonded by using heat welding method to ensure the joint firmly. In the process of pouring concrete, attention should be paid to fully tamping to achieve the full combination of water stop belt and concrete.
