The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in ChinaSan Jose, When the concrete strength can ensure that its surface and edges are not damaged due to formwork removal, Low cost, fast time, no loss, free from climate and place constraints. The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, which is caused by the Chengdu grouting pipe manufacturer&#;s failure to smooth (flatten) the grouting pipe along the horseshoe surface.Answer: Yes, the elastic extension speed of the grouting pipe can be defined within a certain range in the design,San JosePipe shed and small conduit, but for a grouting pipe that has been designed, its elastic extension speed is certain.

The following aspects shall be paid attention to during the construction of grouting pipe: when the construction personnel are binding reinforcement and erecting formwork, reliable fixation measures must be taken for the buried grouting pipe to avoid displacement during concrete pouring and ensure the correct position of the grouting pipe in the concrete. When fixing the grouting pipe, only the allowable part of the grouting pipe can be perforated, and the body part shall not be damaged. The grouting pipe shall be fixed according to the construction specifications required by the design. The common fixing methods are: using additional reinforcement; Fixed with special fixtures; Fix with lead wire and formwork. No matter what fixing method is adopted, the grouting pipe must be positioned accurately, without damaging the effective part of the grouting pipe, so as to facilitate concrete pouring and tamping. During the construction of the grouting pipe,San JoseSmall conduit manufacturer, there are many sharp stones and sharp edged reinforcement in the concrete, so when pouring, vibrating and positioning the grouting pipe, attention should be paid to the impact force of pouring and vibrating, so as to avoid piercing the grouting pipe due to excessive force.?Most of the grouting pipes on the market are meters in stock and some construction sites have different requirements, so there are few in stock. In fact, which can be described as a hundred holes. One end of this pipe has plugs, sharp and round, depending on the customer&#;s requirements. The other end is welded with reinforcing bars from the pipe section to prevent the pipe section from tearing. This kind of pipe is called steel flower pipe. Steel flower pipe is generally used for high-speed maintenance grouting to protect mountains and prevent landslides. Holes are drilled on the steel flower pipe, which is more conducive to the penetration of cement mortar liquid into the rock and soil mass of the rock stratum and to the anchoring. In order to prevent the hole from being blocked by stones, sometimes the design requires reinforcement to protect the hole. After grouting, the pipe orifice must be closed, so as not to let the grouting liquid flow out. The general classification of grouting pipe models can be divided into ordinary standard connection and pipe hoop connection according to their different connection methods. The grouting pipe is specially used as a channel for the depth detection of pile foundation and for structural stress calculation. The grouting pipe is a small pipe, but this small pipe meets the standard sensitivity of sound reception. As long as there is a small sound, it can measure it and accurately reflect the data on the computer or sound receiver. During the concrete pouring of cast-in-place pile, a channel that allows the ultrasonic probe to be normally placed at the pile bottom is reserved, which is not considered in the structural stress calculation.Installation conditions,The commonly used standard for grouting pipe is the inner diameter of -mm. The wall thickness of the pipe has little effect on the sound transmission, so there is generally no need to restrict the thickness of the pipe wall. However, from the perspective of saving steel consumption, it is OK if the pipe wall can bear the lateral pressure of new concrete, not necessarily the thicker the better. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found it should be repaired. If necessary, the steel beam spacing of maolehan grouting pipe shall also be adjusted according to the ambient temperature during installation. XF type grouting pipe device shall be slowly put into the groove, so that the center line of the joint coincides with the center line of the actual reserved joint, and the deviation shall not exceed mm. Meanwhile, the inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of its steel beam shall be adjusted according to the longitudinal, transverse slope and elevation to be ~ mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation.

Can the stretching speed of grouting pipe be defined?Standard requirements,Can the stretching speed of grouting pipe be defined?Calculation formula of weight per linear meter of pile foundation grouting pipe (unit: kg / M)They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process, transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth,San JoseGrouting pipe, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete.San JoseIt is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in ChinaBefore the installation of the grouting pipe, it is necessary to check whether the processed support is vertical to the grouting pipe fitting, and correct the non vertical support; Then install the grouting pipe on the bracket and fasten it. The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold
