The application fields of grouting materials are various, such as equipment foundation, structural reinforcement, steel structure column base, prefabricated components, prefabricated building, water conservancy, electricity and wind power. In addition to the product itself, improper construction is likely to lead to problems in the use of high-strength non shrink grouting materials. How to quickly find the problems and solve them quickly to save the whole construction period. The following is a summary of common problems in grouting material construction that Jinan putty powder manufacturer has explained to you.

缺棱掉角

Missing edges and corners

（1）模板設(shè)計(jì)未考慮防止拆模掉角因素状堰；

(1) The template design did not consider the factor of preventing the removal of formwork from falling corners;

（2）木模未提前濕潤(rùn)蓝鹿，澆注后木模膨脹造成高強(qiáng)無(wú)收縮灌漿料角拉裂；

(2) The wooden mold was not moistened in advance, and the expansion of the mold after pouring caused the high-strength non-shrinkage grouting material corner to crack;

（3）模板縫不嚴(yán)糯驯，漏漿贰往；

(3) Loose formwork joints and grout leakage;

（4）模板未涂刷隔離劑或涂刷不佳，造成拆模粘連耙福；

(4) The template is not coated with isolation agent or poorly coated, resulting in adhesion during mold removal;

（5）拆模過(guò)早過(guò)猛伊厉，拆模方法及程序不當(dāng)；

(5) Premature and excessive demolding, improper demolding methods and procedures;

（6）養(yǎng)護(hù)不好坦冠。

(6) Poor maintenance.

洞口變形

Deformation of the opening

（1）模內(nèi)頂撐間太大形耗，斷面太小；

(1) The top support space inside the mold is too large and the cross-section is too small;

（2）模內(nèi)無(wú)斜頂撐激涤，剛度不足拟糕，不能保持方正；

(2) There is no diagonal support inside the mold, and the stiffness is insufficient to maintain squareness;

（3）高強(qiáng)無(wú)收縮灌漿料不對(duì)稱澆注將模擠偏昔期；

(3) Asymmetric pouring of high-strength non shrinkage grouting material will cause the mold to deviate;

（4）洞口模板與主體模板固定不好已卸，造成相對(duì)移動(dòng)。

(4) The fixing of the opening template and the main template is not good, causing relative movement.

錯(cuò)臺(tái)

Wrong platform

(1)放線誤差過(guò)大硼一；

(1) Excessive setting out error;

(2)模板位移變形累澡，支模時(shí)無(wú)須直找正措施;

(2) The displacement and deformation of the formwork do not require direct alignment measures during formwork support;

(3)下層模板頂部?jī)A斜或漲模，上層模板糾正復(fù)位形成錯(cuò)臺(tái);

(3) The top of the lower formwork is tilted or expanded, and the upper formwork is corrected and reset to form a wrong platform;

板縫高強(qiáng)無(wú)收縮灌漿料澆筑不實(shí)

Inadequate pouring of high-strength non-shrinkage grouting material for plate joints

(1)板縫太小般贼，石子過(guò)大;放線誤差過(guò)大愧哟；

(1) The seam of the board is too small, and the stones are too large; Excessive setting out error;

(2)縫模板支吊不牢、變形哼蛆、漏漿蕊梧；

(2) Inadequate support, deformation, and leakage of joint formwork;

(3)縫內(nèi)雜物未清，或縫內(nèi)布管沮念；

(3) Unclear debris inside the seam, or laying pipes inside the seam;

(4)無(wú)小振動(dòng)棒插搗或不振搗或振搗不好配亮。

(4) No small vibrating rod inserted or not vibrated or poorly vibrated.
