Description

Conical sprayer for slope concrete

Technical Field

The utility model discloses the technique belongs to the building engineering construction technology field, in particular to solve collection and running device of technical problem and slope concrete resilience material such as slope concrete vibration is not closely knit, the porosity is big, easy percolating water.

Background

In the traditional construction method of slope concrete such as slope roofs and silos, because of the existence of natural slopes, the concrete can be integrally glidingly piled up due to vibration in a normal vibrating rod mode, the thickness can not be guaranteed, the concrete can not be vibrated compactly, and defects can be left in final forming. In reality: 1 or make upper and lower double-deck template, open the hole of vibrating according to the certain interval at upper template and vibrate, nevertheless because can not see the condition of vibrating often appear excessively vibrating and leak and shake and can't guarantee structural strength and easy percolating water. 2 or manually divide the small bins on the upper layer steel bars of the double-layer steel bar mesh, and pour the small bins in sequence, so that the concrete below the upper layer steel bars can still slide downwards, and the problem cannot be solved fundamentally although the concrete can be slightly relieved. 3, the method of beating by adopting simple tools such as shovels and the like slightly compacts the surface of the newly poured concrete, and the concrete can not be really compacted. The traditional method is not sufficient, the phenomena of incompact concrete, large porosity and uneven thickness can occur, and the adverse effects on the durability, strength and waterproofness of the concrete are generated, so that the defect exists up to now.

according to the detection method, the same batch of C30 concrete is subjected to contrast detection, a detection object is made into test blocks with the areas of 1.5m multiplied by 1.5m and the thicknesses of 150 mm, 300 mm and 450 mm respectively, sampling is carried out in a core drilling sampling mode with the diameter of phi 100, and the sampled product is subjected to compactness contrast test. The method is specifically divided into three groups: the first group is a detection group; the second group is a reference group; the third group is a control group:

and (3) detection group:

the detection group is a detection object formed by adopting the technical scheme of 'method and device for improving compactness by spraying concrete on a slope' in a patent application, namely the detection object is formed by adopting a process technology of wet spraying concrete on the slope and adding a vibrator for vibrating; as shown in examples 1-3, the slope was 30 °, 60 °, 75 °.

The detection method of the detection group comprises the following steps: the bottom opening of the conical spraying cover corresponds to a surface to be sprayed; starting the jet pump to make the concrete sprayed from the concrete spray opening pass through the conical spray cover and then be sprayed on the surface to be sprayed, and starting the vibrating device of the conical spray cover to make the conical spray cover vibrate while assisting in spraying; the bottom opening of the conical spraying cover is always contacted with the surface to be sprayed for vibration in the process of starting to move the conical spraying cover after the concrete is tamped from the observation opening, the flat edge is always contacted with the vibrating surface,

reference group:

the reference group is a detection object formed by using a traditional vibrating rod vibrating process on a horizontal plane;

comparison group:

the contrast group is a detection object formed by using a current common spade to flap and form on a slope structure; the slope is 30 degrees, 60 degrees and 75 degrees;

the following table specifically shows:

in the table, a first test block is 30 degrees, a second test block is 60 degrees, and a third test block is 75 degrees;

in the table, a first test block is 30 degrees, a second test block is 60 degrees, and a third test block is 75 degrees;

in the table, a first test block is 30 degrees, a second test block is 60 degrees, and a third test block is 75 degrees;

from the macroscopic view of the formed concrete: the detection group and the reference group have no obvious visible holes or bubbles, and the comparison group has obvious visible holes or bubbles. In conclusion, the technology fills the defects of incompact vibration, large porosity, poor durability, low structural strength, easy water leakage and the like of the concrete structure of the slope.
