Изобретение относитс к технике испыта .ни грунтов методом динамического зондировани п|ри инженерно-геологических изыскани х .The invention relates to a technique for testing soils using the method of dynamic sounding of engineering geological surveys.

Известны устройства дл диналгического зондировани , вклю чающие съемный конический наконечник и колонну цилиндрических штанг.Devices for dynamic sensing are known, including a removable conical tip and a column of cylindrical rods.

Наиболее близким техническим решением вл етс наконечник дл дкиамического зондировани грунтов, включающий корпус с вружииным фиксаторюм.The closest technical solution is a tip for dyamic soil sounding, including a housing with an external lock.

Недостатки известных наконечников дл динамиче-ского зондировани заключаютс в одноразовом использовании наконечника, в отсутствии иравильной конической поверхности наконечника, в невозможности уменьшить диаметр наконечника в местах соединени .шарниров с поворотными полукольцами.The disadvantages of the known tips for dynamic sounding consist in the single use of the tip, in the absence of the etching conical surface of the tip, in the impossibility to reduce the diameter of the tip at the joints of the hinges with the rotary half rings.

Целью изобретени вл ете повышение производительности устройства.The aim of the invention is to increase the productivity of the device.

Это достигаетс тем, что в наконечннке дл динамического зондировани грунтов, включаюшем корпус с прул :инньш фиксатором, корпус выполнен с парными выточками и парны:ми ок1нами и снабжен установленным на нем с помощью фиксатора кольцом, а также сегментами , размещенными в окнах, и щечками, расиоложенными в выточках, причем сегмен1У и щечкн зафиксированы на корпусе посредством кольцевой пружины, а щечки соединены с кольцом посредством плоского пружинного фиксатора.This is achieved by the fact that in the tip for dynamic sounding of soils, including the case with prul: inn clamp, the case is made with a pair of undercuts and paired: windows and equipped with a ring mounted on it with the help of a clamp, as well as segments placed in the windows and cheeks , located in the recesses, with the segmen1U and cheeks fixed to the housing by means of an annular spring, and the cheeks are connected to the ring by means of a flat spring retainer.

На фиг. 1 показан наконечник, общий вид;FIG. 1 shows a tip, a general view;

на фиг. 2 дан разрез А-А на фиг. 1: на фпг. 3 - разрез Б-Б на фиг. 2.in fig. 2 shows section A-A in FIG. 1: on fpg. 3 shows a section BB in FIG. 2

Наконечник дл динамического зоидированн грунтов состоит из корпуса 1 с пружииным фиксатором 2, причем корпус 1 выполпен с парньгми выточками 3 и парными окнами 4 и снабжен установлеппьп на нем с помощью фиксат-ора 2 кольцом 5, а также закрепленными кольцевой пружиной 6 сегментами 7, размеще-нными в окнах 4, и щечками 8,The tip for dynamic zoidirovany soil consists of a housing 1 with a spring clamp 2, and the housing 1 is made with a pair of recesses 3 and paired windows 4 and is equipped with a ring 5 installed on it using a fixing-2 2, as well as fixed 7 annular spring 6 segments -nn in windows 4, and cheeks 8,

расположенными в выточках 3 и соедпиог:нымИ с кольцом 5 иосредством илоско1о пружинного фиксатора 9.located in the recesses 3 and connecting with the ring 5 by means of a spring retainer 9.

Работа наконечника дл динамического зондировани грунтов производитс в следующей последовательности.The work of the tip for the dynamic sensing of soils is performed in the following sequence.

Claims

Using a surface hammer, the tip is immersed with a rod (column shtang). Since the diameter of the eyepick is larger than the diameter of the staple, the ground resistance to the tip loading is perceived by the lower conical surface of the housing 1, the cheeks 8 and the segments 7. The cheeks 8 fit snugly to the housing 1. § connected to the ring 5 Fixed latch 2 fixed in the initial polysolation. Segments 7 fit snugly to the cheeks 8 and are also held in the 4 ring harulny windows 6. When the probe is lifted from the well, the body 1 of the tip segments 7, rings and the spring 6 and the spring retainer 2 move upwards. Due to the compressive effect of the soil, the cheeks 8, the spring clips 9 and the ring 5 do not move at first, and the spring clamp acts

2. When the length of the vertical movement of the housing 1 is greater than the height of the segment 7, the released segments 7 under the action of the annular spring 6 are displaced in a horizontal direction to the axis of the spring. Then the ring 5 (after contact of its lower end with the housing 1) also begins to move upward, dragging the cheeks 8 with spring clips 9. With the further lifting of the probe from the well, the segments 7 are held in the windows 4 by the ring spring 6, and the cheeks 8 are occupied by the bottom spring The position is below the housing 1 and moves upwards with it. After the probe is lifted from the well, the tip is cleared of soil, all parts of the tip are returned to their original position. The soil test at the new sensing point is performed by the same tip. Claim for dynamic probing of soils, including a housing with a spring lock, characterized in that, in order to improve the performance of the device, the housing is made with small grooves and twin windows and is equipped with a ring, as well as segments, placed in the windows and cheeks located in the recesses, with the segments and cheeks fixed to the housing by means of an annular spring, and the cheeks are connected to the ring by means of a plane of the spring retainer.
