Description

Technical Field

[0001] The invention relates to the field of construction engineering management, and in particular to a quality supervision method and system for cast-in-place pile concealed engineering. Background Art

[0002] In the hidden project of bored piles (rebar cage), raw steel bar is one of the important building materials that affects the quality of project construction. According to the requirements of the quality supervision specifications for bored pile construction, the model and specifications of the raw steel bar actually used on site must meet the requirements of the construction design drawings, and the amount of steel bars of the corresponding model and specifications must also meet the design requirements. In addition, the raw steel bar materials entering the site for bored pile construction must be submitted to a third-party testing agency for quality inspection before they are used in construction. Only when the quality is qualified can they be used in construction. There is currently a lack of effective supervision measures for the construction and use of raw steel bar materials in the construction of hidden bored pile projects (rebar cages), resulting in quality problems such as inconsistency between construction and design, use of steel bars without inspection, and cutting corners at the construction site.

[0003] At present, there are digital management methods and systems for the entire process of bored pile construction, which can digitally collect and manage the construction process data of each bored pile, and also cover hidden projects (rebar cages). Therefore, based on the existing data of the entire process of bored pile construction, a quality supervision method and system for the hidden project (rebar cage) of bored piles can be constructed. For the use of steel raw materials in the construction process of the hidden project (rebar cage) of bored piles, the whole process quality supervision is carried out from material planning, material receipt, material inspection, material inspection and material use. All-round quality supervision is carried out from the time dimension, model specifications and usage, which can better meet the quality supervision specification requirements of the hidden project (rebar cage) of bored piles. Summary of the invention

[0004] In view of the shortcomings of the prior art and the actual demand for construction quality supervision of cast-in-place pile concealed engineering (reinforcing cage), the present invention proposes a quality supervision method and system for cast-in-place pile concealed engineering.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] According to a first aspect of the present specification, a quality supervision method for cast-in-place pile concealed engineering is provided, the method comprising the following steps:

[0007] Step 1: Digitally define the parameters of the reinforced cage of the bored pile, and register the design parameters of the reinforced cage of each bored pile, including the main reinforcement, spiral stirrups, and stiffening stirrups, in accordance with the requirements of the bored pile concealed engineering-reinforced cage construction design drawings;

[0008] Step 2: Register and manage the receipt of steel bar raw materials during the construction of the cast-in-place pile concealed project - steel cage, record the arrival time, furnace batch number and receipt quantity of each steel bar model and specification, and upload the corresponding steel bar raw material quality certificate and receipt documents;

[0009] Step 3: Register and manage the steel bar raw materials delivered to the site for the cast-in-place pile concealed project - steel cage construction, record the inspection time and inspection results of each steel bar model and specification, upload the inspection report, and associate the inspection submission record with the receipt record, and record the number of inspection representatives.

[0012] Step 6: According to the inspection time of the steel bar raw material inspection report associated with each cast-in-place pile, the time of lowering the cast-in-place pile steel bar cage is verified and supervised. If the inspection time of the steel bar raw material is later than the lowering time of the cast-in-place pile steel bar cage, it means that the cast-in-place pile has an abnormal situation that the steel bar raw material is used before inspection;

[0013] Step 7: Based on the construction data of the steel cage lowering registered during the construction of the cast-in-place pile concealed project - steel cage, including the data of spiral stirrups, stiffening stirrups and each section of main reinforcement, the steel bar usage of each cast-in-place pile is summarized and counted according to the steel bar model and specifications;

[0014] Step 8: For the cast-in-place piles associated with the steel bar raw material inspection report, sort them in chronological order according to the time of pile construction, combine the calculated and statistical steel bar usage of each cast-in-place pile corresponding to the steel bar model and specification, and compare it with the number of inspection representatives of the steel bar model and specification corresponding to the associated steel bar raw material inspection report, supervise the steel bar usage of the cast-in-place piles corresponding to the steel bar model and specification, and identify the cast-in-place piles with abnormal steel bar usage.

[0023] Step 5.1 compares the model and specification data of the main reinforcement of each section of the reinforced cage of each cast-in-place pile registered when the reinforced cage is lowered with the model and specification design data of the main reinforcement of the reinforced cage of the corresponding section. If the model and specification are lower than the design data, it is determined that the main reinforcement of the reinforced cage of the cast-in-place pile has abnormal use;

[0024] Step 5.2 compares the corresponding model and specifications of the spiral stirrups / reinforcing stirrups of the steel cage registered when the steel cage of each cast-in-place pile is lowered with the design data of the corresponding model and specifications of the spiral stirrups / reinforcing stirrups of the steel cage registered for the cast-in-place pile. If the model and specifications are lower than the design data, it is determined that there is an abnormal use of the spiral stirrups / reinforcing stirrups of the steel cage of the cast-in-place pile.

[0035] The steel bar amount S 加劲箍筋 The calculation formula is: 加劲箍筋 =(total cage length / spacing+1)×weight per meter×circumference, where circumference=3.1416×(pile diameter-2×thickness of steel cage protective layer) / 1000+10D, D is the diameter of the reinforcing stirrups registered when the steel cage is lowered, and the weight per meter is calculated according to "square of the main reinforcement steel specification×0.617 / 100".

[0036] Furthermore, the step eight specifically includes:

[0037] Assume that the representative number of steel bar model specification X in the steel bar raw material inspection report is R x , detect the number of remaining representatives R x剩余 =R x , the ordered n-tuple (B1, B2, ..., B n ), where B i represents the pile number of the i-th pile, B i+1 The pile formation time is later than B i Pile time;

[0038] For B i , i is initialized to 1, get B i The amount of steel bars S for the pile corresponding to the steel bar type and specification X x-i , and R x剩余 contrast:

[0039] If S x-i >R x剩余 , then it means B i The amount of steel bars corresponding to the steel bar model specification X of the pile has exceeded the representative number of the test, B i There is an abnormality in the amount of steel bars used in the pile on the steel bar model specification X. i+1 To B n The piles all had the same abnormal condition;

[0040] If S x-i ≦R x剩余 , then it means B i The amount of steel bars used for the pile corresponding to the steel bar model specification X has not exceeded the number of representative tests, B i If there is no abnormality in the amount of steel bars used in the pile on the steel bar model specification X, then the remaining representative quantity R is recorded. x剩余 =R x剩余 -S x-i , and execute i=i+1 to detect the steel bar usage of the next pile corresponding to the steel bar model specification X.

[0057] Figure 2 It is a structural block diagram of the system of the present invention. DETAILED DESCRIPTION

[0058] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and Examples.

[0059] like Figure 1 As shown, an embodiment of the present invention provides a quality supervision method for cast-in-place pile concealed engineering, the method comprising the following steps:

[0060] Step 1: Define the complex cast-in-place pile reinforcement cage parameters digitally, and configure and manage the reinforcement cage design parameters of each cast-in-place pile in accordance with the requirements of the cast-in-place pile hidden project-reinforcement cage construction design drawings, including: spiral stirrup configuration, stiffening stirrup configuration, and each section of main reinforcement configuration.

[0061] Step 1.1 Digitally define the parameters of the steel cage of the cast-in-place pile, which can be represented by a four-tuple (P, B, G, D), where P represents the cast-in-place pile project; B represents the pile number; G represents the overall design parameters of the steel cage; and D represents the main reinforcement design parameters of each section of the steel cage. G can be represented by a six-tuple (LC, LJ, MGCD, BHCHD, LXGJ, JJGJ), where LC represents the length of the steel cage; LJ represents the diameter of the steel cage; MGCD represents the anchorage length; BHCHD represents the thickness of the protective layer; LXGJ represents the design parameters of the spiral stirrup, including the length of the reinforced area, the spacing of the reinforced area, the length of the non-reinforced area, the spacing of the non-reinforced area, and the steel bar model specifications; JJGJ represents the design parameters of the stiffening stirrup, including the diameter, spacing, and steel bar model specifications. D can be represented by a triple (Di, DLC, ZJ), where Di represents the i-th section of the steel cage; DLC represents the length of the steel cage of this section; and ZJ represents the main reinforcement design parameters, including the number of main reinforcements and the steel bar model specifications.

[0062] Step 1.2: According to the requirements of the bored pile construction design drawings, the design parameter values ​​of the reinforcement cage of each bored pile shall be registered according to the digital requirements.

[0063] Step 2: Register and manage the receipt of steel bar raw materials during the construction of the cast-in-place pile concealed project - steel cage, record the arrival time, furnace batch number and receipt quantity of each steel bar model and specification, and upload the corresponding steel bar raw material quality certificate and receipt documents to ensure the authenticity of the steel bar raw material receipt data.

[0064] Step 3: Register and manage the steel bar raw materials delivered to the construction site for the cast-in-place pile concealed project - steel cage construction, record the inspection time and results of each steel bar model and specification, upload the inspection report, and associate the inspection submission record with the receipt record, and record the number of inspection representatives. It is also necessary to ensure that all receipt records are associated with the corresponding inspection submission record, and ensure that the receipt quantity is consistent with the number of inspection representatives.

[0065] Step 4: Register and manage the lowering of the steel cage during the construction of the hidden project of cast-in-place piles - steel cage, record the construction data of each section of each steel cage, register and manage the overall construction data of the steel cage of the cast-in-place pile when the steel cage is lowered, and associate it with the corresponding steel raw material inspection report to ensure that each cast-in-place pile used steel raw material has a corresponding steel raw material inspection report.

[0066] Step 4.1 During the construction of the cast-in-place pile concealed project - steel cage, register the construction data of each steel cage lowering section, and record the lowering time, section, length, number of main bars and steel model specifications of the steel cage section.

[0067] Step 4.2 When the cast-in-place pile reinforcement cage is lowered, the overall construction data of the cast-in-place pile reinforcement cage shall be registered, including: reinforcement cage length, reinforcement cage diameter, anchorage length, protective layer thickness, spiral stirrup construction data (such as: length and spacing of the reinforced area / non-reinforced area, reinforcement model specifications), and stiffening stirrup construction data (such as: diameter, spacing, reinforcement model specifications).

[0068] Step 4.3 For each cast-in-place pile, associate the corresponding steel bar raw material inspection report according to the steel bar model and specifications used (including: main bars, spiral stirrups, and reinforcing stirrups).

[0069] Step 5: Compare the construction data of the steel bar model and specifications registered during the lowering construction of each cast-in-place pile reinforcement cage with the design parameter values ​​of the corresponding steel bar models and specifications of the main bars, spiral stirrups, and stiffening stirrups registered for the cast-in-place pile to identify cast-in-place piles with abnormal steel bar use.

[0070] Step 5.1 compares the model and specification data of the main reinforcement of each section of the reinforced cage of each cast-in-place pile registered when the reinforced cage is lowered with the model and specification design data of the main reinforcement of the reinforced cage of the corresponding section. If the model and specification are lower than the design data, it is determined that there is an abnormal use of the main reinforcement of the reinforced cage of the cast-in-place pile.

[0071] Step 5.2 compares the corresponding model and specifications of the spiral stirrups / reinforcing stirrups of the steel cage registered when the steel cage of each cast-in-place pile is lowered with the design data of the corresponding model and specifications of the spiral stirrups / reinforcing stirrups of the steel cage registered for the cast-in-place pile. If the model and specifications are lower than the design data, it is determined that there is an abnormal use of the spiral stirrups / reinforcing stirrups of the steel cage of the cast-in-place pile.

[0072] Step six: According to the inspection time of the steel raw material inspection report associated with each bored pile, the lowering time of the bored pile steel cage is verified and supervised. If the inspection time of the steel raw material is later than the lowering time of the bored pile steel cage, it means that the bored pile has an abnormal situation of "using the steel raw material before inspection".

[0073] Step 7: Based on the construction data of the steel cage lowering registered during the construction of the cast-in-place pile hidden project - steel cage, including the data of spiral stirrups, reinforcing stirrups and each section of main reinforcement, the steel consumption of each cast-in-place pile is summarized and counted according to the steel model and specifications.

[0074] Step 7.1 For each cast-in-place pile, the amount of steel bars corresponding to the steel bar model and specification of each steel cage main bar can be calculated based on the construction data of each steel cage section. The specific calculation method is as follows (assuming that the number of steel cage sections is k):

[0075] (1) Calculate the steel consumption S of each main reinforcement of the 1st to k-1th reinforcement cage i (1≦i≦k-1), the calculation formula is: S i = (length of the i-th section + length of the joint) × number of main bars in the i-th section × weight per meter, where the joint length is related to the main reinforcement model and specifications of the steel cage in this section, and is calculated according to "main reinforcement diameter × 10 / 1000"; the weight per meter is calculated according to "square of the main reinforcement specification × 0.617 / 100";

[0076] (2) Calculate the steel consumption S of the main reinforcement of the kth section of the reinforcement cage k , the calculation formula is: S k = (length of section k + anchorage length + joint length) × number of main bars in section k × weight per meter, where the joint length is still calculated according to "main bar diameter × 10 / 1000"; the weight per meter is still calculated according to "square of main bar specification × 0.617 / 100";

[0077] (3) According to the steel bar model and specifications, calculate the steel bar consumption S of each cast-in-place pile reinforcement cage main bar 主筋 =∑S i +S k , 1≦i≦k-1.

[0078] Step 7.2 For each cast-in-place pile, the steel bar consumption of the spiral stirrups and stiffening stirrups corresponding to the steel bar model and specifications of the cast-in-place pile can be calculated based on the overall construction data of the steel cage registered when the steel cage is lowered. The specific calculation method is as follows:

[0079] (1) Calculate the amount of steel bars S in the spiral stirrup reinforcement area 加密区 , the calculation formula is: S 加密区 = (length of the densified area × 1000 / densified area spacing + 1) × perimeter × weight per meter, where perimeter = 3.1416 × (pile diameter - 2 × thickness of the steel cage protective layer) / 1000, and the weight per meter is still calculated according to "square of the main reinforcement specification × 0.617 / 100";

[0080] (2) Calculate the steel quantity S in the non-reinforced area of ​​spiral stirrups 非加密区, the calculation formula is: S 非加密区 = (length of non-reinforced area × 1000 / spacing of non-reinforced area + 1) × perimeter × weight per meter, where perimeter = 3.1416 × (pile diameter - 2 × thickness of steel cage protective layer) / 1000, and weight per meter is still calculated according to "square of main reinforcement steel bar specification × 0.617 / 100";

[0081] (3) Calculate the amount of steel bars S for reinforcing stirrups 加劲箍筋 , the calculation formula is: S 加劲箍筋 =(total cage length / spacing+1)×weight per meter×circumference, where circumference=3.1416×(pile diameter-2×thickness of steel cage protective layer) / 1000+10D, D is the diameter of the reinforcing stirrups registered when the steel cage is lowered, and the weight per meter is still calculated according to "square of the main reinforcement steel bar specification×0.617 / 100".

[0082] Step 7.3 For each cast-in-place pile, the steel consumption S of the main reinforcement, spiral stirrups and reinforcing stirrups can be summarized according to the steel bar model specification X. x =S 主筋 +S 加密区 +S 非加密区 +S 加劲箍筋 .

[0083] Step 8: For the cast-in-place piles associated with the steel bar raw material inspection report of the associated cast-in-place piles (one steel bar raw material inspection report can be associated with multiple cast-in-place piles), sort them in order of pile construction time, combine the calculated and statistical steel bar usage of each cast-in-place pile corresponding to the steel bar model and specification, and check it with the number of inspection representatives corresponding to the steel bar model and specification of the associated steel bar raw material inspection report, supervise the steel bar usage of the cast-in-place pile corresponding to the steel bar model and specification, and identify the cast-in-place piles with abnormal steel bar usage. The specific algorithm is as follows:
