Description

Technical Field

[0001] The utility model belongs to the technical field of rockfill concrete test piece processing, in particular to a rockfill concrete super-large test piece processing device. Background Art

[0002] At present, rockfill concrete construction technology is a new large-volume concrete construction technology that utilizes a large amount of rockfill. The volume ratio of rockfill in concrete can generally reach 50%-55%, which can make full use of primary mined stones or large stones in excavated materials, and greatly reduce the amount of cementitious materials. Among them, the conventional method for the performance index of rockfill concrete is to use a 150mm cubic test mold to make a self-compacting concrete specimen, and characterize the strength of rockfill concrete after the experiment, which cannot fully reflect the actual situation. This device needs to make an extra-large specimen, a cube with a size of 450mm. The large specimen made by this method is close to the prototype, which can reflect the actual performance index of rockfill concrete to a certain extent. Utility Model Content

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] Example:

[0021] like Figures 1 to 4 As shown, a processing device for a super-large specimen of rockfill concrete includes a chamber 1, a pipe A2 and a cutter 5. A material 3 is arranged in the chamber 1. The chamber 1 is a cubic structure with an opening upward. The pipe A2 is arranged in the chamber 1. The pipe A2 is a drainage pipe. The cutter 5 is arranged on the material 3. The material 3 is rockfill concrete. The cutter 5 is a rope cutter. According to the site conditions, the chamber 1 can be L, H or other shapes. The pipe A2 and the pipe B6 can be made into L, H or other shapes according to the conditions of the chamber 1 and arranged reasonably, so as to obtain more types of data and be closer to the actual construction conditions.

[0022] The material part 3 comprises a test piece 4, and the test piece 4 is a cube. The test piece 4 can be made into a prism or other shapes according to the test index requirements, so as to obtain more types of data and be closer to the actual construction situation.

[0023] The chamber 1 is provided with a through hole 101 and a pipe B6, and the pipe B6 passes through the chamber 1 through the through hole 101. A plurality of through holes 101 are symmetrically arranged linearly at the bottom of the side of the chamber 1, and both ends of the pipe B6 pass through the chamber 1 through the through holes 101 respectively.

[0024] The pipe A2 is disposed through the pipe B6.

[0025] The four corners on the top of the chamber 1 are respectively provided with positioning grooves 7, which are arranged in an arc shape, and a support frame 8 is arranged at the bottom of the chamber 1. The support frame 8 is arranged in a shape corresponding to the positioning groove 7, so that the chambers 1 can be stably stuck through the positioning groove 7 when stacked, which is convenient for reducing the floor space when multiple chambers 1 are used.

[0026] The sealing member 10 is disposed on the through hole 101 to seal the unused through hole 101 . After the sealing member 10 is placed in the through hole 101 , the end thereof is flush with the inner wall of the chamber 1 .

[0027] The processing method of the rockfill concrete specimen processing device of the utility model comprises the following steps:

[0028] Step 1: Cast chamber 1 with rockfill concrete using the same conditions, process and materials as the project at the construction site;

[0029] Step 2: burying pipes B6 along the short sides at the bottom of the chamber 1, the pipes B6 being pipe materials such as PVC pipes or steel pipes, and pouring rockfill and / or concrete to obtain rockfill concrete material pieces 3;

[0030] Step 3: Use the rope cutter 5 to penetrate the buried pipe B6;

[0031] Step 4: cutting the rockfill concrete material 3 by a rope cutter 5 to form a rockfill concrete specimen block 4;

[0032] Step 5: Conduct relevant tests on the rockfill concrete specimen block 4.

[0033] In step 1, the rockfill concrete material 3 is the same as the corresponding engineering project material, and is cured under the same conditions after pouring.

[0034] In step 2, pipe B6 is buried first. After the material 3 is laid, pipe A2 is inserted into the inside of pipe B6, and then pipe B6 is pulled out from chamber 1; this facilitates the reuse of pipe B6 and saves costs, and at the same time prevents pipe A2 from being crushed and damaged during the laying of material 3.

[0035] In step 3, the chamber 1 uses a rope cutter 5 to penetrate the buried pipe B6 for cutting to obtain a rockfill concrete specimen block 4; after curing to the age, it is convenient to pass through a rope saw for cutting to carry out cutting.

[0036] In step 5, the rockfill concrete specimen block 4 is transported to a processing plant with a higher precision for large specimens, and is processed with precision while ensuring the requirements of flatness, verticality, etc. The rockfill concrete specimen block 4 can be subjected to relevant tests.
